Southeast Asia’s Oil and Gas M&A Market Is Heating Up

Southeast Asia's upstream oil and gas M&A market has shifted from IOC exits to buyers targeting growth, with Rystad Energy identifying about $9.6 billion of upstream assets likely to be marketed through the rest of this year and in 2027. In 2025 roughly $6.7 billion of assets changed hands driven by strategic entry rather than the non-core disposals that dominated 2020–2024.

Why It Matters

The change in deal intent signals a competitive buying cycle that could push valuations higher for producing and near‑development assets, reshaping regional portfolios as majors, independents and national oil companies pursue different growth strategies.

Key Facts

  • Total assets on offer (rest of year + 2027): $9.6 billion
  • Assets sold under growth intent in 2025: ~$6.7 billion
  • Split of the $9.6 billion by buyer type: Majors $3.6B; Independents $3.7B; NOCs $1.4B; others remainder
  • Recent transaction multiples (development assets): $9.8 per boe (recent) vs $6–7 per boe six‑year average
  • Recent transaction multiples (pre‑FID resources): Over $3 per boe (recent) vs $1.5 per boe six‑year average for pre‑FID resources

Rystad Energy says Southeast Asia’s upstream M&A market has turned from a period of majors exiting late‑life positions to one in which buyers are actively pursuing growth. The consultancy estimates about $9.6 billion of upstream assets will be offered across the remainder of this year and in 2027, with roughly $6.7 billion of assets having traded in 2025 under this new strategic intent. That marks a departure from 2020–2024, when dealflow was driven largely by non‑core sales tied to production sharing contract expiries and portfolio pruning. Transaction metrics have risen as competition increases. Development assets in recent deals reached around $9.8 per barrel of oil equivalent (boe), and pre‑FID resource transactions exceeded $3 per boe — both above six‑year averages (about $6–7 per boe for development assets and $1.5 per boe for pre‑FID resources). Rystad highlights that winning future bids will require more than capital; bidders will need credible value‑creation plans to justify higher premiums. The $9.6 billion pipeline of assets is split nearly evenly between majors and independents, with national oil companies (NOCs) holding a smaller share. According to Rystad, majors are reshaping portfolios to concentrate on core basins while pursuing frontier acreage through partnerships, independents are seeking outside capital to progress pre‑FID discoveries to final investment decisions, and NOCs are selectively rationalizing domestic late‑life assets as they eye strategic entries abroad. Opportunity is concentrated in a limited set of basins and PSCs. Rystad identifies nearly 45 PSCs across 12 provinces holding about 2.8 billion boe of net resources and roughly 145,000 boepd of production, with 72% of resources in pre‑FID status and 18% producing. Notable assets include Vietnam’s Ken Bau (about 3.7 Tcf recoverable) and pre‑FID gas positions in Sarawak, the Andaman Sea, and the Kutei Basin. The producing tranche, though smaller in volume, is highly contested and has recently commanded premiums near $8 per boe, with Chevron’s North Malay Basin stake singled out as a major opportunity.
