Petroleum activities both in the Joint Development Area (JPDA) and Exclusive Area (TLEA) are conducted according to Production Sharing Contracts (PSCs) signed between the oil companies and the National Petroleum and Minerals Authority (ANPM), or its predecessor the Timor Sea Designated Authority (TSDA). Under Article 30.1(a)(i) of Timor-Leste's 2005 Petroleum Act and Article 20.1(a) the Interim Petroleum Mining Code for the JPDA, all PSCs signed after that date are public documents. The 2005 legislation also included model PSCs for the TLEA and JPDA, which serve as templates for the PSCs for each specific area.

In 2016, Timor-Leste enacted Decree-Law 32/2016 (also Portuguese) to regulate offshore Petroleum Operations in the TLEA. Decree-Law 18/2020 (Port.) was enacted in 2020 to cover petroleum operations onshore.

With the entry into force of the Australia-Timor-Leste Maritime Boundary Treaty in August 2019, the Joint Petroleum Development Area ceased to exist, although Greater Sunrise will continue to be under a bi-national special regime. New contracts had to be signed for each project. (See map below.)

Annual reports from the TSDA are no longer on an official website, but you can get them here for 2003, 2004, 2005, 2006 and 2007.

Additional information about petroleum activities through 2022 is in Timor-Leste's reports to the Extractive Industries Transparency Initiative (EITI), available here.

Bidding round in 2019-2022

At the Timor-Leste Oil and Gas Summit in October 2019, the country opened its first public bidding round for new contract areas in 13 years. As shown on the map at right, virtually the entire country, both onshore and in the Timor Sea, is available, except for the north coast and a few areas with existing contracts.

The Covid-19 pandemic has caused many countries to extend or postpone bidding rounds for new petroleum exploration, and in July 2020 Timor-Leste extended theirs by one year, with bids due by October 2021. A few weeks before the deadline it was extended for four months more.

On 3 June 2020, the government published Resolution 3/2020 reserving up to 20% of each new contract for TimorGAP.

On 17 June 2020, the Norwegian seismic company TGS announced that it had begun a project with ANPM to combine all available data on offshore Timor-Leste into a single database to "impart confidence in [companies'] license round decision-making processes."

The organizers of the 2019 Summit held another (virtually) in July 2020, including a presentation by ANPM's Mateus da Costa on the bidding round. In December, they published an interview with him. A third (virtual) Summit was held in March 2021.

When the bidder pre-qualification period ended on 14 January 2022, nine companies had been qualified and four were still being reviewed. Bids were opened (FB video) on 5 March, with seven companies bidding for six of the 18 blocks, as follows:

On 12 April 2022, ANPM informed bidders and the public that the announcement would be delayed a week due to Easter and the election. Winners were announced on 22 April (see table and map at right):

EnergyVoice called the results "disappointing."

The winning bidders had until 29 June to sign the contracts, but on 8 November ANPM announced that the process was taking longer than expected, and would be finished by February 2023, although no announcement had been made by June.

Contract TL-OT-22-18 with TimorGAP for Block A ("Rarahana"), was signed on 22 December 2022; details below. A year later, Contract TL-SO-22-23 was signed with Eni for Block P; details below. In March 2024, Contract TL-OT-22-22 was signed with HTS for Block F; details below,

Santos withdrew from Block R for hydrocarbon exploration, preferring to look into its potential for future Carbon Capture and Storage. In April 2025, ANP accepted Santos' withdrawal, and the company will pay $150,000.

Onshore PSCs TL-OT-17-08 and 09 awarded without tender in 2017

On 7 April 2017, the ANPM awarded two contracts for onshore oil and gas exploration to a joint venture equally owned by Timor Resources and TimorGAP.  Timor Resources, which is part of the Australian Nepean Group of companies, will be the operator for PSC TL-OT-17-08 (Covalima and Bobonaro municipalities, area A on map at right) and PSC TL-OT-17-09 (Manufahi and Ainaro municipalities, Area C), totalling 2,000 square kilometers.
   The contracts were celebrated by Timor-Leste's government (also 7 MB video), ANPM, TimorGAP and Timor Resources (also Technical press release). Although Timor-Leste's project proponents hoped for "maximum benefits for Timor," Australian news coverage in NT News and the Financial Review expected Darwin to benefit economically by providing logistical supply, as well as a possible refinery.
   In 2017, Timor-Leste held public consultations on draft regulations for onshore petroleum operations, and La'o Hamutuk made a submission.
    In August 2018, Timor Resources announced the award of a seismic exploration contract to BGP Indonesia. Seismic exploration began in October 2018.
    In September 2019 environmental assessment for drilling started, and drilling was expected to begin in March 2020.  Links to draft EIA and draft EMP from February 2020, which also include appendices on Waste mgmt (A), Rehabilitation (B), Redress (C), Oil spill response (D), Traffic mgmt (E), Noise mgmt (G), Incident reporting (H), Community consultation (I) and Air quality (J). Newer environmental documents for this project have been updated in La'o Hamutuk's environmental registry.
   On 16 January 2020, amendments were issued to the two PSCs, extending their areas by several km into the sea, modifying the decommissioning contract and adding specificity to the Local Content projects. Download addenda to PSC17-08 and PSC17-09 (also English).
   In April 2020, due to Covid-19 and the drop in worldwide oil prices, Timor Resources decided to suspend the project for 4-7 months until the situation changes. Initial drilling will not happen before October, if then. In July, Lusa reported that they hope to start drilling in late 2020 or early 2021.
   After years of deliberation and delays, Decree-Law 18/2020 regulating onshore petroleum operations was officially published in May 2020.
   A revised Environmental Management Plan for area -08/A was approved in December 2020, with appendices covering Waste management, Rehabilitation, Redress, Oil spill response, Traffic management, Inspection schedule, Noise management, Incident reporting, Community consultation and Air quality.
   In January 2021, Timor Resources announced that they plan to drill the first of five wells in Covalima (area -08/A, see map) in July, but they were later delayed. The ANPM granted an environmental license in July, and drilling the first well is scheduled for 21 September.
  ANPM held public hearings on the environmental license for the Rusa-1 test well near Betano (area -09/C, see map) in August and September in Manufahi and Ainaro, and relevant documents are in La'o Hamutuk's environmental registry. On 13 September, La'o Hamutuk wrote a 7-page submission to this process, with the following main points, as well as a blog: Onshore oil drilling imminent despite serious concerns:

• The consultant and proponents of this project have no experience with oil drilling, so special caution must be taken.

• This assessment should include the entire project cycle, including production if significant oil is found.

• Climate change should be taken more seriously.

• The analysis of impacts is insufficient and biased, and local communities have not been informed.

• Decommissioning and restoration plans are incomplete.

• Economic benefits are exaggerated.

• This process has several conflicts of interest that make it hard to protect the public interest.

• Public consultation should include listening to the people, and be well-informed and without intimidation.

• Timor Resources' corporate culture obstructs public participation.

On 1 February 2022, ANPM issued an environmental license for the Rusa-1 test well in Ainaro.
  Timor Resources drilled the first test well in Covalima (called Feto Kmaus or Karau-1), in October-November 2021, but the results were discouraging. A gas kick caused oil-contaminated mud to spill over into nearby areas, prompting an emergency response.
  They drilled a second Covalima well (Kumbili-1) in January-February 2022. On 15 March, Timor Resources announced that they found "hydrocarbon shows of significance" at Feto Kmaus and, as data evaluation proceeds, intend "to raise additional capital". Energy Voice reported that "there are no firm figures yet, but plenty of hope."   In April 2022, Timor Resources began withdrawing from the area including the Feto Kmaus test well, as they did not plan any further exploration there. They informed the landowner that they are terminating the lease early. In December, La'o Hamutuk's Bulletin included an article Konsultasaun iha perfurasaun mina no gás iha Covalima, sharing observations on the pre-drilling consultation.
   In March 2023, joint venture partners Timor Resources and TimorGAP engaged in a public squabble about whether TimorGAP should pay part of the exploration costs. TimorGAP denied any obligation, but Timor Resources reasserted in May that TimorGAP should reimburse some of the $68 million it has invested in the project to date. In mid-2023 the new government pledged to settle the dispute; the Council of Ministers approved a resolution in March 2024 and the two companies signed revised commercial agreements in May.
   Exploratory drilling at the Lafaek well in Labarai, Covalima was completed in April 2023, and TR was waiting for analysis by an Indonesian laboratory. In October 2023, Timor Resources claimed to have found 32 million barrels of contingent resources, as reported in the trade press and by ANP. In February 2024, ANP told Tatoli that Timor Resources would drill another test well to see if the discovery was worth developing.

   In July 2023, La'o Hamutuk researcher Jonathan Gonsalves presented Entre Esperansa ho Realidade ba Perfurasaun Mina Rai iha Covalima (mós PDF) to the Timor-Leste Studies Association conference, as well as in an article in the December 2023 LH Bulletin.
  In March 2024, Timor Resources announced the publication of a Competent Persons Report on the oil prospects of seven contracted areas which it hopes could be up to "20,000 barrels/day for twenty years".
  In anticipation of more drilling, Timor Resources met with community leaders around Feto Kmaus in April 2024, with further discussions in July and November. In May, Timor Resources sought a drilling company and supervisor. TR extended the search in September and invited expressions of interest in February 2025.
  In June 2025, Timor Resources shared a summary of an independent resource audit that Molyneaux and associates had conducted for them, which found 20mmBOE of (2C) contingent resources and 800mmBOE of (2U) prospective resources in their contract areas.

Estimates from Timor Resources' consultant, June 2025

On 7 December 2021, ANPM awarded PSC TL-OT-21-17 (summary in Portuguese) to TimorGAP without open bidding. The seven-year contract covers a 1,575 km² area in three municipalities: Viqueque, Manufahi and Manatuto.

La'o Hamutuk attended a socialization event for this project on 24 June 2022, and wrote a blog TimorGAP begins exploring Pualaca Block by itself. Two months later, ANPM issued an environmental license for a gravity survey.

In May 2023, TimorGAP invited bids for a 2D seismic survey, and in November 2024 they awarded the $7.4 million job to BGP from China. Link to relevant environmental documents. On 11 January 2025 Prime Minister Gusmao formally launched the survey in Natarbora, and it will begin in March.

The third contract, PSC TL-OT-22-22 (also Portuguese) from the 2019-2022 bid round was for Block F, 844 km² in the southern part of Viqueque municipality. ANP signed the contract with the company HTS from Kazakhstan on 8 March 2024, as reported by Tatoli and the Government. ANP posted the PSC to its website six weeks later.
   In September 2024, ANP announced that the PSC had just become effective.
   In May 2025, HTS looked for a consultant to provide environmental licenses support services for the project.

Contract SO-15-01 awarded to TimorGAP without tender

SO-15-01: On 22 December 2015, Resolution 44/2015 (Portuguese original) came into force, awarding one block in the Timor-Leste Exclusive offshore area and one onshore block to TimorGAP to conduct 3D seismic studies and sign Production Sharing Contracts by direct award, without a public tender. ANPM announced the offshore award in January 2016 and later published a summary and eventually the text of PSC SO-15-01 on its website.
  The Chinese company BGP started offshore seismic research the next day and handed the results over to TimorGAP and ANP on 10 March 2016. TimorGAP will pay BGP $11.4 million over the next three years for the study.
   In November 2016, the Jornal da Republica published a Portuguese summary and maps for both the onshore and offshore PSC.  The onshore area was later divided into PSCs TL-OT-17-08 and OT-17-09, described above.
   On 5 July 2017, TimorGAP announced that it had identified "world-class prospectivity" in the offshore block, based on initial analysis of old seismic data.

The second contract PSC TL-SO-22-23 (also Portuguese) from the 2019-2022 bid round was for Block P, a 3,998 km² offshore area just south of Greater Sunrise. ANP signed it with the Italian company Eni on 14 December 2023.
   In February 2025, Eni began preliminary consultations on their seismic exploration planned for 3q2025, including meetings with La'o Hamutuk and the NGO Forum.
   On 24 February, the ANP announced that TimorGAP is taking a 12.5% interest in the project, exercising the state’s legal right of participation.
   In May 2025, Eni announced a public consultation on their draft EIA and EMP for seismic exploration.

Chuditch contract TL-SO-19-16 awarded to Sunda Energy (formerly Baron Oil) and TimorGAP

In the first new contract signed after the Boundary Treaty came into effect, on 8 November 2019 ANPM awarded a no-tender contract to Singapore-based SundaGas (75%, operator) and TimorGAP (25%) for a 3,571 km² area in the former Joint Development Area. It is part of former Minza contract area JPDA 06-101A, which includes the Chuditch gas prospect. PSC TL-SO-19-16 (Portuguese)
  One-third of SundaGas is owned by the British company Baron Oil Plc., which described the project on its website based on Shell's 1998 test well. In April 2020, Baron Oil reinforced its ownership.
  On 9 July 2020, SundaGas VP Colin Murray presented to an online conference about the project, and he made a similar presentation on 25 March 2021.
  In January 2021, citing Covid-19 and problems with data access, SundaGas asked ANPM to extend the time by one year, until December 2022, for them to analyze seismic data and decide whether to drill a test well. Baron Oil updated investors on the project in April, and acquired the remainder of SundaGas's share of Chuditch in June.
  A January 2022 presentation by Baron Oil described why "This year is going to be important for Chuditch & Baron", which was echoed in the trade press two months later. In September, SundaGas presented an update to an industry conference in Perth.  The following month, ANPM granted the company's request to delay the decision on drilling until June 2023.
  In February 2023, Baron Oil released a Competent Person's Report estimating the potential Chuditch reserve. In early June, Baron Oil announced that ANPM had granted a six-month extension to "contract year two" to 18 December 2023, giving the operator until then to decide whether to drill a test well. In October, Baron Oil presented information about their possible appraisal well, which they considered their "priority this year" in their previous six-month results statement. According to a media report, Baron is considering a floating LNG plant for the field.
  Chuditch optimism increased in November 2023, reinforced by an Operational Planning Update from the company. Baron subsidiary SundaGas asked for Expressions of Interest for their offshore drilling operations, expected to begin in the last quarter of 2024. In early December, the ANP granted another six-month extension of "year two" until 18 June 2024.
  In mid-December 2023, SundaGas signed an MOU with TimorGAP, which will increase TG's share of the project from 25% to 40%. TimorGAP will now be responsible for 20% of all costs, and TG's obligation during 2024 is estimated at $7.5 million, in addition to $1 million for "back costs."  The farm-up agreement was signed on 24 January 2024 and approved by the ANP the following week. Baron Oil is proceeding with a site survey.
  In February 2024, Baron Oil issued new shares to raise money for the Chuditch test well. The following month, CEO Andy Yeo and another director resigned from Baron's board. Yeo was replaced by Andy Butler, who had been director for Asia-Pacific.
  In March, Baron Oil subsidiary SundaGas completed their geophysical site survey, and decided to move the planned Chuditch-2 appraisal well 286 meters. They are discussing drilling plans with potential subcontractors.
  Baron Oil continues to promote the project with potential investors, including presentations to the Association of International Energy Negotiators and the Proactive One2One Investor Forum. Baron Oil's 2023 Annual Report also highlights their plans for Chuditch.
  In May, following their withdrawal from the North Sea and Peru, Baron Oil changed their name to Sunda Energy to reflect its focus on Southeast Asia. Chuditch is now their only project, for which they continue to seek investors.
  In June, Sunda Energy and the ANP circulated Terms of Reference for the process of getting a Timor-Leste environmental license for their appraisal (exploratory) well, which they hope to drill in 2025. Link to relevant environmental documents.
  In October and November, Sunda released an Operational Update and fact sheet, following on their video promotion in September.
  On 3 December 2024, Sunda made a webinar presentation Building an Asian Gas Champion. A week later, they made a non-binding agreement with an unnamed drilling company for a test well to be drilled in the second quarter of 2025. On 12 December, Sunda, the Government and TimorGAP signed a non-binding MOU to evaluate a Chuditch development concept which would tie into the proposed LNG plant in Natarbora.

Kuda Tasi/Jahal contract signed in 2013 in the Joint Petroleum Development Area

JPDA 11-106 with Eni (40.53%), Inpex (35.47%) and TimorGAP (24%) was signed on 13 April 2013 without an open bidding process. It covers 662 square km of relinquished acreage from JPDA 06-105, near the Kitan field, and was expected to tie into Kitan if a commercial discovery is made while Kitan is in production. Operator Eni committed to drill two exploration wells in the area, which includes the Kuda-Tasi and Jahal oil reservoirs, within two years.
   The signing was announced by ANP. This was the first exploration contract for Timor-Leste's state-owned oil company TimorGAP, and it was celebrated by TimorGAP, INPEX and Timor-Leste's government. ANP published the PSC (12 MB) text to their website seven months later (scanned text), after the Jornal da Republica published a summary.
    In August 2014 Eni announced plans to drill two wells in this contract area in 2015, and details about these plans became available in October 2014. However, due to low world market prices for oil, the drilling was repeatedly delayed, and in 2016 the ANPM agreed to extend the term of the PSC until 2018.
    Kitan ended production in the second half of 2015, and its processing ship departed the area before this block was ready.
    In October 2018, Eni signed a contract with Maersk Drilling to drill one well in March 2019. The well, known as Kanase-1, did not find commercial quantities of oil.
   After the Maritime Boundary Treaty came into force, this contract was replaced by PSC TL-SO-T-19-11.
   In August 2024, the Australian company Finder Energy Holdings Ltd announced (also presentation) that it is purchasing 76% of this PSC from Eni and Inpex for $2 million (plus more money if Finder develops the field). TimorGAP still owns the remaining 24%. Having obtained ANP approval, the two companies signed the revised PSC on 6 September (ASX announcement, corporate presentation). Finder is seeking investors, and then will design the Field Development Plan, with the intention of making a Final Investment Decision for Kuda Tasi/Jahal in 2026. In November, Finder published an update, and MST Access and Stockhead helped promote the project.
  In January 2025, Finder told oil industry media it was leaning toward an FPSO development model. They issued an upbeat update on their 3D Seismic Reprocessing Project in mid-February and another on their dynamic modelling, and appointed Luis Pereira as their representative in TL. Stockhead and GeoExPro continued to publish Finder's upbeat thoughts.
  In May, Finder presented the Kuda Tasi and Jahal Oil Development Opportunity at a conference in Singapore. They also looked for companies to provide integrated Drilling Management Services (DMS), FPSO Production Management Services (PMS) and Development Subsea, Umbilical, Riser and Flowline (SURF) services. Finder announced the completion of their Ikan 3D data reprocessing project.
  In June, Finder updated its presentation. After brief confusion, they signed a strategic alliance with SLB (formerly Schlumberger) to devlop the FEED for Kuda Tasi/Jahal, promoting it in the trade press.

At the end of 2014, Minza announced that the company was in liquidation. ANPM announced the termination of the contract in January 2016.
   A new contract for part of this area was awarded to SundaGas and TimorGAP in October 2019 -- see above.

Contracted and relinquished areas over time

The map above is from 2010. By the start of 2015, many of these contract areas had  been completely or partially relinquished as unproductive, except for the areas shown below:

By 2017, the Oilex and Minza contracts were terminated, and TimorGAP had received a new TLEA area and, with Timor Resources, two new onshore areas. Green lines show where offshore seismic exploration has been conducted:

The Maritime Boundary Treaty came into effect in August 2019. Existing PSCs were adapted, and TimorGAP was awarded one new contract, as shown in the following maps:

In 2022 and 2023, the first contracts were signed from the recently-completed bidding round:

JPDA 06-102 with Petronas (50%), Korea Gas (30%), Samsung (10%) and LG (10%). (summary)

JPDA 06-105 (replaced part of JPDA 03-01) with Woodside (40%), INPEX (35%), Talisman Resources (25%).
In September 2007 Woodside sold its share to Eni, although it avoided taxes on the deal. This area contains the Kitan field which began production in October 2012 and is estimated to contain 34.6 million barrels of oil.
  In April 2013, Eni (with TimorGap and INPEX) signed PSC 11-106 (above) to explore further in the relinquished parts of this contract area.
  In April 2014, Talisman said that it wanted to sell its share of this project, and in June, Malaysian company Hibiscus Petroleum announced it would purchase Talisman's share of Kitan for $18 million, but Hibiscus cancelled the sale on 1 June 2015. The entire Talisman company, including this 25% share, was acquired by the Spanish company Repsol in May 2015.  Kitan revenues dropped sharply in 2014 to less than one-sixth of their 2013 levels, largely because the field is nearly depleted. At the beginning of September 2015, Eni announced it will terminate its contract with the processing platform ten months early. Kitan stopped production in December 2015, and in 2018 Timor-Leste repaid $63 million in profit oil tax revenues that had been overestimated in the past.
   After the Maritime Boundary Treaty came into force in 2019, this contract was replaced by PSC TL-SO-T-19-10.

Contracts signed before 2006 in the JPDA

Contracts signed before the 2005 laws went into effect are not legally obligated to be published. La'o Hamutuk and others have repeatedly asked the oil companies and relevant authorities to give permission for them to be made available. These contracts will be replaced by new ones after the 2018  comes into force.

Bayu-Undan

   The partners in the Bayu-Undan joint venture have agreed to publish parts of the contracts, although many paragraphs have been censored. Bayu-Undan is the only currently producing field providing revenue to Timor-Leste. These contracts also include the Elang-Kakatua field which ceased production in 2007. From 2009-2020, partners in Bayu-Undan were ConocoPhillips (57%), Santos (11%), Inpex (11%), Eni (11%), Tokyo Electric(later JERA)/Tokyo Gas (9%).

• JPDA 03-12 (Public Information Notice) with ConocoPhillips, Santos, Inpex, Petroz and Emet (signed on 2 April 2003 to replace an occupation-era contract) was amended in May 2003.

• JPDA 03-13 (Public Information Notice) with ConocoPhillips (signed on 2 April 2003 to replace an occupation-era contract) was amended in May 2003.

 As Bayu-Undan neared depletion, three more wells were drilled in 2018 to extract as much oil as possible. However, production is still expected to end by 2022.
   On 30 August 2019, the Maritime Boundary Treaty between Timor-Leste and Australia entered into force. Two days earlier, the PSCs for Bayu-Undan were replaced by ones which recognize that the JPDA no longer exists, and the entire field is now in Timor-Leste's territory. Under the Treaty, 'conditions equivalent' prevail for ConocoPhillips, Santos, Inpex and the other partners. Timor-Leste published summaries of the new PSCs TL-SO-T 19-12 and TL-SO-T 19-13.
   On 14 October 2019, ConocoPhillips announced that it is selling its entire 57% share in Bayu-Undan and Darwin LNG, as well as its shares in Barossa and other fields, to Santos for $1.4 billion. In March 2020, Santos announced that it will on-sell 25% of B-U and DLNG to SK E&S for $390 million. After approval from partners and regulators in both countries, the CP-Santos deal became operational on 28 May 2020, as announced by Santos and ConocoPhillips. After the transactions are complete, partners in Bayu-Undan and Darwin LNG joint ventures will be Santos (Australia, 43.4%), SK E&S (Korea, 25%, as of 30 April 2021), Inpex (Japan, 11.4%), Eni (Italy, 11.0%) and JERA/Tokyo Gas (Japan, 9.2%).
   At the end of May 2020, about 19 million barrels equivalent of proved oil and gas reserves remained  in the Bayu-Undan field; about 3% of the amount that has already been extracted and sold.
   On 9 July 2020, Santos Bayu-Undan Development Team Leader Michel Buoniauto presented to an online conference. As later reported by Upstream, he said that Santos is considering drilling three more wells to suck up the last drops from the field.
   Like all companies, Santos (which owned more than 2/3 of Bayu-Undan and Darwin LNG) struggled in the Covid economy, and wrote down the value of some of its assets. The company's second quarter 2020 report showed significant drops in Bayu-Undan production (see table at right) and pointed out that the field has higher production costs than other Santos assets.
   Production picked up in the third quarter, as Santos explained: "spot cargo sales which partially offset customers exercising contractual flexibility on LNG cargoes. The two spot cargoes loaded in August and September 2020 were the first to be marketed by Santos on behalf of Darwin LNG since Santos assumed operatorship and were the two largest cargoes ever loaded at DLNG. Evaluation of a further phase of infill drilling in Bayu-Undan continues to be progressed in order to optimise field recovery and extend field life and Darwin LNG production. The planned program consists of an additional three development wells..."
   On 5 January 2021, Santos announced the Final Decision to Invest $235 million to drill three more production wells at Bayu-Undan in mid-2021, which are expected to recover an additional 20 million barrels and extend the life of the field. The additional costs will  be recoverable from revenues which would have gone to Timor-Leste. Following support from Timor-Leste authorities, Santos started drilling the new wells on 25 May, with better-than-expected results. Year-end 2021 production reports show a slight increase in gas production compared with the previous two years, although liquids production has dropped relative to 2019.
   World LNG prices surged in late 2021 and early 2022, and gas production from Bayu-Undan (running at half-capacity) was lucrative for Timor-Leste. Timor-Leste is preparing to clean up the Bayu-Undan floating platform at the new port at Tibar as part of decommissioning, and has begun an environmental licensing process. Santos shipped the last liquefied gas extracted from Bayu-Undan in November 2023, and decommissioning has begun. Although the Darwin LNG plant is no longer operating, Santos continues to provide small amounts of gas from Bayu-Undan to Darwin to sell to the domestic NT market. Santos' quarterly report for 4q2024: "The facility shut down for maintenance in mid-September and restarted late November 2024.  Bayu-Undan will continue to support the Northern Territory by supplying domestic gas into this market, provided it remains economic."
   As the Bayu-Undan PSC neared expiration in August 2024, Timor-Leste pressured Santos to give part of the nearly-empty project to TimorGAP, and Santos and its JV partners agreed to transfer 16% ownership in return for extending the contract through June 2026. Under the extended PSC, which was signed on 16 September, the shares are now held by Santos (Australia, 36.5%), SK E&S (Korea, 21%), TimorGAP (TL, 16%), Inpex (Japan, 9.6%), Eni (Italy, 9.2%) and JERA/Tokyo Gas (Japan, 7.6%). TimorGAP has no obligation for decommissioning costs, and will not receive part of the surplus if some of the $1.3 billion in reserve for decommissioning is not needed.
   In early 2025 Weststar-GAP (an aviation company jointly owned by TimorGAP and a Malaysian company) signed an agreement to provide helicopter services to the Bayu-Undan offshore platform.
   In May 2025, MPRM and TimorGAP agreed to form a PPP with the Swiss company Streamtec to explore designing a gas pipeline from Bayu-Undan to Natarbora.
   Bayu-Undan production ceased on 4 June 2025, notwithstanding plans for future activities there. Upstream called it a setback for Timor-Leste, coming simultaneously with delays in the Chuditch test well.

Carbon Capture and Storage (CCS) in Bayu-Undan

On 3 May 2021, Santos and Eni agreed to look into using the Bayu-Undan field, which will soon be exhausted, to store carbon dioxide underground in an effort to reduce their contribution to climate change. As described in La'o Hamutuk's blog Carbon Capture and Storage under the Timor Sea: Climate Change Prevention or Carbon Colonialism?, this controversial project could allow the companies to develop carbon-intensive gas fields in Australian territory, including Barossa and Evans Shoal, without increasing the companies' overall carbon footprint. The proposal, which will require approval from Timor-Leste, would allow Santos to delay decommissioning the Bayu-Undan project, will make Timor-Leste responsible for Australia's waste, and is likely, overall, to accelerate the negative impacts of climate change.
   Although Santos has great expectations for CCS technology, some shareholders are doubtful. On 13 September 2021, Santos and the ANPM signed an MOU (also Tetum) to discuss moving ahead with this project. At the end of October, notwithstanding serious expert concerns, Santos' CEO Kevin Gallagher lauded it to an industry conference in Darwin. The following week, Gallagher met with ANPM officials on the margins of the climate change conference in Glasgow.
   In November, La'o Hamutuk presented on the CCS project to an Australian environmental webinar (video).

  In February 2022, the Northern Territory Environment Protection Authority held a consultation on Santos' proposed Darwin Pipeline Duplication Project which would enable CO2 to be separated from Barossa gas in Darwin and piped to Bayu-Undan. La'o Hamutuk made a submission, which was reported by Energy Voice and described in a press release. Expert analysis indicates that the project may not reduce the amount of CO2 released into the atmosphere.

  In June 2022, three Japanese companies indicated their interest in joining the project, and a Final Investment Decision was planned for 2023. In July 2022, Santos contracted Worley to prepare a Front End Engineering Design for the CCS project.

  In December, LH gave a presentation Carbon Capture and Storage (CCS) at Bayu-Undan (also PDF).

  Although the Barossa project has been delayed by Australian regulators, Santos and ANPM continue to promote CCS at Bayu-Undan.

   In June 2023, LH made a second submission to the Northern Territory Environment Protection Authority.
   The Australian Parliament is considering new Sea Dumping legislation to allow carbon dioxide waste produced in Australia to be pumped into international waters, which independent MPs consider a "colossal attempt at greenwashing" and "a key enabler of gas expansion, granting social licence for new and highly polluting greenwashed fossil fuel projects."
   On 7 August 2023, Santos announced that the Bayu-Undan joint venture partners had signed an MOU with TimorGAP to share information and explore partnership opportunities for a CCS project at Bayu-Undan. The Korean company SK E&S is also interested in storing CO₂ in Bayu-Undan, In November, Australia revised its Sea Dumping law, a concept questioned by the Center for International Environmental Law, Energy Tracker, the IEA and the IEEFA (page 9).
   On 23 January 2024, relevant Ministers from Timor-Leste and Australia discussed the project. Although the Timor-Leste government has yet to enact legislation to enable this project, IFC is supporting it. Despite many legal challenges, Santos is proceeding with the Barossa/CCS project, and the company is going after civil society groups who question it. They hope to start Barossa operation in the third quarter of 2025.
   In October 2024, Santos' Quarterly Update on Barossa did not mention the CCS project, although Santos' Third Quarter report to ASX said "Bayu-Undan CCS project FEED (technical engineering activities) is over 90% complete and expected to conclude in the coming months. Focus is now on working with Timor-Leste government regarding implementation of required regulatory and fiscal frameworks, approvals, government to government agreements (with Australia) and commercial agreements to make the project FID ready."
   Also in October, the Institute for Energy Economics and Financial Analysis (IEEFA) published Bayu-Undan: A test bed for carbon trading or a distraction? with these key findings:

• Greater transparency is needed about Santos’s proposed Bayu-Undan CCS project, including the costs and quantity of CO2 likely to be sequestered, and whether Santos will need to buy additional carbon credits to offset emissions from its Barossa gas project.

• Santos should provide a decommissioning plan for existing infrastructure at Bayu-Undan, including the costs and the timeline.

• Santos must demonstrate how it will meet its targets given CCS’s history  of underperformance, including at Chevron’s Gorgon project, and  provide the cost implications of any underperformance of the Bayu-Undan CCS project.

• Investors will require transparency on the liability issues associated with any potential CO2 leaks from the Bayu-Undan CCS project. Australia and Timor-Leste will need to reach an agreement on liability provisions given the project is in Timor-Leste waters.

Peter Sainsbury then published Carbon capture and storage – what’s the real goal? to explain "deception" by the fossil fuel companies.
   At the end of November, Santos persuaded an Australian judge to order the Environmental Defenders Office to pay them nearly USD $6 million because EDO's failed legal challenge to the undersea pipeline linking Barossa to Bayu-Undan had delayed the project.
   In February 2025, Santos' Climate Transition Action Plan 2024 reported that "The Bayu-Undan CCS technical engineering activities are nearing completion..." They also promoted the project in their 2024 Full-year results presentation. In their first quarter 2025 report, Santos wrote: "Bayu-Undan CCS project FEED (technical engineering activities) is 97 per cent complete. Efforts remain centred on working with the Timor Leste government to establish the necessary regulatory and fiscal frameworks, approvals, government-to-government agreements (with Australia), and commercial agreements to advance the project toward FID readiness."
  In May, Santos tried again to advance the project with President José Ramos-Horta.  Energy Intelligence reported that the project seems  stalled, but Timor-Leste's leaders continue to promote it, especially after Bayu-Undan production ended on 4 June.
  Notwithstanding some environmental and safety hiccups, Santos expects Barossa production to begin in the third quarter of 2025. CCS, if it happens, will come later.

Buffalo (terminated)

The Buffalo oil field sits just west of the JPDA, in territory that became Timor-Leste's when the Maritime Boundary Treaty with Australia entered into force in 2019. Discovered in 1996, it had previously been occupied by Australia. Buffalo produced 20 million barrels of oil for BHP from 1999 until it was decommissioned in 2005, and Australia is keeping those revenues. In May 2016, Australia signed a new Buffalo contract with the Carnarvon company, which believes that it can extract about 31 million more barrels with new technology, by drilling smarter and deeper than the earlier wells.

   After the Treaty was signed in 2018, Carnarvon reported "that Carnarvon and Timor-Leste are in agreement on achieving first oil as soon as possible. Special legislation is to be enacted to ensure the Buffalo redevelopment will continue under equivalent fiscal terms previously in place with Australia." In May 2018, Carnarvon described the project, after which Carnarvon announced that it had raised investor capital for its first well. In August, Carnarvon updated its information, planning to drill 1-3 wells beginning in Q2 2020. Although it was clear that the field would be in Timor-Leste's sovereign territory before any test wells were drilled, in September 2018 Carnarvon asked Australian regulator NOPSEMA for environmental approval, and NOPSEMA requested changes and then accepted their plan in May 2019. Timor-Leste told Carnarvon that they would not have to comply with Timor-Leste environmental licensing laws, and Carnarvon told their investors that "the approval of the Environmental Plan to drill three wells into the Buffalo field by NOPSEMA will be accepted by the regulator in Timor-Leste."

   When the Treaty came into force on 30 August 2019, Carnarvon explained the new regime under PSC TL-SO-19-14 (Port., also English).  They hired Angelo Lay, former Commercial Director for ANPM, as their country manager. In Timor-Leste, Decree-Law 26/2019 detailed the transition of Buffalo from Australia to Timor-Leste. In its reports to shareholders in June and September 2020, Carnarvon indicated that the wells would be delayed, due to Covid-19 and the reluctance of any other companies to invest in the field. However, on 14 December 2020, Carnarvon announced that Advance Energy will fund drilling in return for a 25-50% share of the PSC. Advance Energy commissioned a Competent Person Report to validate their investment.

   Carnarvon issued a project update on 15 February 2021, and began looking for a drilling company. However, some oil industry experts are skeptical about the project, while others believe it could provide up to $600 million in revenues for Timor-Leste. In May, Carnarvon announced that Petrofac will drill the well, financed with $20 million from Advance Energy. In September, they contracted a drilling rig from Valaris and hoped to drill in November.

   After further delays, the rig was mobilized on 22 December, and drilling began on 31 December 2021. The first week went as planned, and the companies issued another update on 14 January. However, the update on 19 January was less promising, leading to reports that the project would be terminated. Five days later, Carnarvon and Advance Energy announced that the project is "uncommercial" which was reported in the trade press. The CEO of Advance Energy resigned a few days later. In October 2022, Carnarvon's 2022 Annual Report recognized that the company had lost $30 million on the now-abandoned Buffalo project. In July 2023, Carnarvon confirmed that it was giving up on the project. In January 2025, ANP announced that the PSC was terminated on 16 December 2024.

Timor-Leste's oil stolen by Australia: Laminaria-Corallina

The Laminaria and Corallina oil fields, just outside the JPDA, are closer to Timor-Leste than to any other country and should belong to Timor-Leste under international legal principles. Since operator Woodside began production in 1999, Laminaria-Corallina has paid more than $2 billion in taxes to the Australian government and not one penny to Dili.

The project spreads over two contract areas:
 * Laminaria was owned 59.9% by Woodside and 40.1% by Talisman
 * Corallina was owned 66.7% by Woodside and 33.3% by Talisman.

   In April 2014, Talisman said it wanted to sell its share of the Laminaria-Corallina project. In May 2015, the entire Talisman company was acquired by Repsol.
   Another deal to sell the field was announced (also Tetum) in May 2016, with both Woodside and Talisman selling their holdings to Northern Oil & Gas Australia, a new company created by former WestSide founder Angus Karoll, and the transfer was finalized in February 2017. Because NOGA is not publicly traded, it is much less transparent than companies listed on stock exchanges.
   Australian authorities repeatedly cited NOGA for environmental violations, and ordered NOGA to cease Laminaria operations in July 2019, after which the company went into 'voluntary administration'.  NOGA went into liquidation in February 2020, and Australia may have to pay $200 million or more in clean-up costs. Australia hired Woodside, the former owner who reaped billions from the field, to provide advice on decommissioning, as analyzed by Callum Foote. In December 2020, the Australian Government announced that it "will now start the process of decommissioning and remediating the fields." By May 2021, it became clearer that Australia will assess oil companies to cover the decommissioning costs. In July, Australia sought a company to decommission the Northern Endeavour FPSO. In November 2021, an Australian Senate committee conducted an inquiry on cost recovery legislation and issued a report. Ongoing developments in Australia are not discussed on this web page.
   The 2018 Boundary Treaty entered into force on 30 August 2019. It says that after Laminaria-Corallina has no recoverable oil left, it may become part of Timor-Leste's territory. We hope it is in a clean, safe and stable condition by then.
   During its 15 years of production, Laminaria-Corallina generated about $6.8 billion in sales for Woodside and its partners, of which about $2.2 billion was paid to the Australian government. Timor-Leste got nothing. Under the Maritime Boundary Treaty, Timor-Leste's government relinquished its claim to this money, but La'o Hamutuk and others continue to remind Australia that it has a moral obligation to repay it.
  In August 2014, NOGA's CEO told President Ramos-Horta that he was interest to invest in Timor-Leste's petroleum sector.

The future

Although results to date have not been very promising, the Government remains optimistic, as shown by their bidding round, conducted in 2019 after a decade of promises and postponement.

In June 2014, the National Petroleum Authority held public consultations on new regulations and model PSCs for the TLEA and onshore areas, and La'o Hamutuk made a submission.

In April 2015, La'o Hamutuk analyzed how much of Timor-Leste's oil and gas wealth is remaining to be exploited, and published Timor-Leste's oil and gas are going fast (also blog and Tetum). In June, we responded (also Tetum) to allegations that our information was unfounded.

This debate continues. On 10 March 2016, La'o Hamutuk explained Santos' report that Bayu-Undan is 93% depleted in Indicators have Consequences.

In June 2017, La'o Hamutuk presented As Bayu-Undan dries up: challenges and opportunities (also PowerPoint and paper). Our 2019 paper After the oil runs dry: Timor-Leste economics and government finances includes additional information about the implications of petroleum dependency.

The Boundary Treaty that took effect in August 2019 opened the way further development of Buffalo, Chuditch, Sunrise and other areas. During 2020, the Covid-19 pandemic and simultaneous fall in global oil and gas prices made many companies and investors more cautious about continuing financially marginal projects, such as those in Timor-Leste.

In 2021 , Charles Scheiner of La'o Hamutuk wrote Timor-Leste: 2021 economic survey: The end of petroleum income (updated version), and the following month the IMF published an Article IV report on Timor-Leste. Both conclude that it would be unwise to expect significant oil and gas revenues to continue for very long, which was confirmed by the Ministry of Finance in Book 1 of the 2022 State Budget (pages 58-61). More recently, the Ministry and others have warned that Timor-Leste may fall over a "fiscal cliff" before 2035 if the economy is not diversified.
