Our Business

PTTEP conducts business in petroleum exploration, development, and production. We are applying advanced innovation and technology to enhance efficiency across our operations. Furthermore, the company is actively studying clean and emerging energy solutions to develop new energy sources for the future and foster long-term sustainable growth.

PTTEP operates over 50 petroleum exploration, development and production projects in more than 10 countries across several regions with the primary focus on Southeast Asia and the Middle East as well as other petroleum-prolific areas displaying investment opportunities.

In Thailand, we are the operator of major petroleum fields, including G1/61, G2/61, Arthit and S1 projects. We also partner in several joint venture projects in both onshore and offshore areas in the Gulf of Thailand.

Overseas, PTTEP invests in many key projects as the operator including the Algeria Hassi Bir Rekaiz Project, a vital oil field of PTTEP in Africa; Block H Project, a gas field in Malaysia; and the SK410B Project in Malaysia where we made our largest-ever gas discovery at Lang Lebah field. The latter is currently in the development phase. Our joint venture projects include the Oman Block 61 Project, a sizable onshore gas block that is crucial for Oman’s domestic market; the Abu Dhabi Offshore 2 Project, where a substantial natural gas reserve was discovered; and the Mozambique Area 1 Project, a large-scale liquefied natural gas (LNG) facility in Africa.

To further support exploration and production business, PTTEP also invest in midstream businesses such as Oman LNG (OLNG), the only LNG facility in Oman; and ADNOC Gas Processing (AGP), the largest onshore gas processing facility in Abu Dhabi, the United Arab Emirates.

Beyond petroleum exploration and production business, PTTEP has diversified into new businesses embracing renewable energy such as offshore wind farm in Scotland, UK and help other industries, apart from energy, in their operations such as agriculture and healthcare industries. Driving these initiatives, we have established subsidiaries including AI and Robotics Ventures Company Limited (ARV), FutureTech Energy Ventures Company Limited (FTEV), as well as Xplor Ventures Company Limited. The latter of which is a corporate venture capital setting up to invest in emerging technology startups.

Among key technologies for future that PTTEP is focusing on is the Carbon Capture and Storage (CCS). PTTEP is studying CCS project development in Thailand and overseas, with an aim to capture carbon emissions from petroleum and other industries. We have initiated Thailand’s first CCS project at Arthit field in the Gulf of Thailand.

Gulf of Thailand Model: Unique E&P expertise for complex geological structure

The Gulf of Thailand Model embodies practical E&P knowledge that PTTEP attained from decades of experience in the Gulf of Thailand. The model enables maximizing hydrocarbons resources from the Gulf of Thailand’s challenging subsurface structure where hydrocarbon reservoirs are scattered over small, dispersed fields, and coupled with high temperature and pressure uncertainties. PTTEP learned and practiced exploration and drilling techniques and optimized the development of complex discoveries at a competitive cost. Known as the “Gulf of Thailand Model”, the knowledge becomes a standard practice that is also applicable to similar regions.

Our Major Discovery

Following multiple gas discoveries in Thailand and various other countries, PTTEP achieved a historic milestone in 2021 with the largest-ever gas discovery and gas reserves in our company’s history at the Lang Lebah-2 well located in the Malaysia SK410B Project the Lang Lebah field is estimated to hold 5–6 trillion cubic feet of gas in place. The project is currently in the planning stage for gas field development.

Carbon Capture and Storage (CCS)

In 2021, PTTEP initiated the research and development of Thailand’s inaugural Carbon Capture and Storage (CCS) project at the Arthit gas field in the Gulf of Thailand. The company has reached the Final Investment Decision (FID), marking the Thailand’s first CCS development and paving the way for the technology to play a significant role in advancing the country’s Net Zero goal. A parallel project is currently underway at Lang Lebah field in Block SK410B, Malaysia. Collaborating closely with fellow members of the PTT Group, we are also actively conducting the feasibility study on the implementation of CCS technology in PTT Group’s operational sites in Rayong and Chonburi provinces in Thailand (Eastern Thailand CCS Hub). Furthermore, PTTEP has engaged in fruitful partnerships with experienced collaborators to assess the feasibility of CCS implementation in various locations within Thailand and other regions of the world.

Large-scale onshore LNG (Liquefied Natural Gas) project in Africa

PTTEP participates in the Mozambique Area 1 Project, the first onshore LNG facilities in Mozambique and a large-scale LNG project in Africa. The project’s first LNG cargo is expected to commence in 2028 from Golfinho-Atum field consisting of initial two onshore liquefaction trains with a combined annual capacity of 13.1 million tons.

The Ghasha Concession

In 2024, PTTEP acquired a 10% participating interest in the Ghasha Concession, one of the largest natural gas fields offshore Abu Dhabi, United Arab Emirates (UAE). This investment expands PTTEP’s footprint in the Middle East and strengthens collaboration with globally experienced partners to drive the project's success.

The Ghasha Concession is located near Abu Dhabi Offshore 2, and Abu Dhabi Offshore 3, where PTTEP already has joint investments, enabling efficient project management. The Concession is expected to produce over 1,500 MMSCFD of natural gas by 2030. Moreover, the project will capture approximately 1.5 million metric tons per annum (MMtpa) of carbon dioxide, making it a net-zero greenhouse gas emissions gas production project.
