CNOOC Limited
China's dominant offshore oil and gas producer, holder of exclusive state E&P rights in Chinese waters.
CNOOC's oil and gas keeps flowing under a state monopoly no company can touch, but its US-listed shares stay exposed to sanctions politics that already cost it a New York listing once.
CNOOC drills for oil and gas in waters off China under exclusive government permission that no other company can challenge. The real threat is not from business rivals like Shell or ExxonMobil, but from US and international sanctions that could make the stock impossible to own or trade, which already happened when it was kicked off the New York Stock Exchange in 2021. The one thing that could change everything is a major shift in US-China relations or a peace deal that reduces sanctions pressure, though current tensions in the South China Sea make that unlikely soon.
H1 2026 interim results (expected around August 2026) show whether Q1 profit rebound holds. Would show if higher oil prices are offsetting cost and capex pressure into mid-2026.
South China Sea clashes reported in July 2026 disrupt or halt CNOOC's offshore production blocks. Would show geopolitical conflict is starting to hit actual output, not just sentiment.
- FY2025 net profit RMB122.1bn, down 11.5% YoY
- Record output: 777.3M BOE in 2025, up 7% YoY
- All-in cost $27.9/BOE, down 2.2% YoY
- US sanction or SDN-style designation directly against CNOOC Limited restricting equity access.
- South China Sea escalation disrupting offshore operations or exploration rights.
- Oil price volatility from Middle East conflict undercutting 2026 profit.
- Capex execution shortfall against RMB112 to 122bn 2026 plan and production target.
- Geopolitical designation risk from parent group's Russia-linked business ties.
| Rival | Direction | Evidence |
|---|---|---|
| PetroChina | contesting | Legally barred from offshore E&P in China; onshore rival with reserves reportedly shrinking as of Dec 2025 |
| Sinopec | contesting | Focused on downstream refining and onshore upstream, roughly 600,000 b/d production in 2025, no offshore claim |
| ExxonMobil | contesting | Co-participant in Guyana's Stabroek block where CNOOC holds a non-operated stake as of March 2026 |
| Petrobras | contesting | Shares Brazil's Buzios and Mero fields with CNOOC, which has 7 of 11 planned projects producing as of March 2026 |
- Is CNOOC profitable in 2026?
- Yes. CNOOC's Q1 2026 net profit rose to RMB39.14 billion as oil prices climbed, reported April 28, 2026, reversing part of the FY2025 decline when profit fell 11.5% YoY to RMB122.1 billion on lower realized oil prices.
- Could AI replace CNOOC?
- No. CNOOC's business is physical offshore oil and gas extraction under exclusive state-granted rights in Chinese waters. AI, including a Huawei smart-oilfield pilot completed in 2025, is used only as an internal efficiency tool, not a substitute for its drilling and reserves assets.
- Who owns CNOOC Limited?
- CNOOC Limited is majority state-owned, held via CNOOC (BVI) Limited, a vehicle of parent China National Offshore Oil Corporation. It trades on the Hong Kong (00883) and Shanghai (600938) exchanges, and was delisted from the NYSE and Toronto Stock Exchange in 2021 under a US executive order.
- Is CNOOC's biggest competitor PetroChina or Sinopec?
- Neither directly. PetroChina and Sinopec are legally barred from offshore exploration in Chinese waters, so CNOOC holds a near-monopoly there. Its real exposure as of March 2026 comes from oil price cycles and geopolitics, not domestic rivals taking share.
- Is it safe to hold CNOOC stock given US sanctions risk?
- There is latent risk. CNOOC Limited was forced off the NYSE and Toronto Stock Exchange in 2021 under Executive Order 13959. As of July 2026 no fresh direct US sanction targets the listed entity itself, but ongoing US-China tensions and South China Sea clashes keep this risk active.
- Is CNOOC growing its oil and gas production?
- Yes. CNOOC reported record net production of 777.3 million BOE in 2025, up 7% YoY, and record proved reserves of 7.77 billion BOE, up 6.9% YoY, announced March 26, 2026, with 2026 guidance targeting 780 to 800 million BOE.
