Southeast Asia's $9.6 Billion Upstream Oil and Gas Sale Spree Heats Up

Southeast Asia's upstream oil and gas sector is witnessing a significant shift, with $9.6 billion in assets set for sale through 2027. Research from Rystad Energy highlights a competitive M&A cycle, driven by strategic entries rather than exits by international oil companies (IOCs). This marks a departure from 2020-2024, when majors primarily divested late-life assets and production sharing contracts (PSCs). Transaction values have surged, with development assets fetching $9.8 per barrel of oil equivalent (boe) and pre-final investment decision (FID) resources exceeding $3 per boe.

The $9.6 billion in assets is nearly evenly split between energy majors ($3.6 billion), independents ($3.7 billion), and national oil companies (NOCs) ($1.4 billion). Majors are selling assets with limited upside to focus on core basins, while independents seek capital to advance discoveries like Harbor Energy's Andaman portfolio. NOCs are rationalizing late-life assets domestically to explore new opportunities abroad. Growth ambitions are concentrated in key basins, with nearly 45 PSCs across 12 provinces holding 2.8 billion boe of net resources.

The next 18 months will be shaped by the conversion of pre-FID opportunities into mega M&A deals, the trajectory of premiums on producing assets, and the evolution of deal structures into strategic partnerships. Buyers will need more than capital to win; the value creation plan behind their offers will be crucial. Notable opportunities include Chevron's stake in the North Malay Basin and Vietnam's Ken Bau field, which holds 3.7 trillion cubic feet of recoverable resources.

While optimism is growing, not all assets are progressing as planned. Eni's Vietnamese portfolio faced setbacks with dry wells, increasing the likelihood of a farm-out for the Ken Bau field. Similarly, Inpex may seek to farm down part of its interest in Abadi LNG to spread development capital, adding to the region's crowded buyer list.
