CNOOC H1 profit jumps 23% to record RMB85.8bn as output hits new high

CNOOC Limited (SEHK: 00883; SSE: 600938) reported record first-half 2026 net profit attributable to shareholders of RMB85.8 billion, up 23.4% year on year, as higher realised oil prices combined with another increase in offshore production. Net production reached a record 398.7 million barrels of oil equivalent, increasing 3.7%, while oil and gas sales revenue rose 20% to RMB206.1 billion.

The combination highlights the operating leverage embedded in CNOOC Limited’s cost structure. The company kept all-in costs at approximately US$29.70 per barrel of oil equivalent while Reuters reported that its average realised oil price increased 23.6% to US$85.49 per barrel. With production also rising, a substantial portion of the improvement in realised pricing could flow through to earnings rather than being consumed by sharply higher unit costs.

What drove CNOOC Limited’s record first-half profit?

Production growth remained broad-based. CNOOC Limited brought five projects on stream during the half, including developments in offshore China and the Buzios 8 project in Brazil, while reservoir management, adjustment wells and workovers helped offset natural decline across mature producing fields. Domestic and overseas production both increased.

The company also continued replenishing its upstream inventory. Four discoveries were announced during the first half and 16 oil- and gas-bearing structures were successfully appraised. Exploration progress included Luda 16-1 and Qinhuangdao 30-3 in Bohai Bay, Enping 11-1 in the South China Sea and additional appraisal work, while CNOOC Limited entered three exploration blocks in Brazil and Indonesia.

The Brazilian expansion is strategically notable because CNOOC Limited acquired operatorship of a pre-salt Santos Basin exploration block for the first time. That adds another layer to an international portfolio where Brazil has already become an important source of production growth.

Can CNOOC Limited keep production growing after reaching 398.7 million boe?

Management retained its 2026 production target of 780–800 million boe. At the midpoint, approximately 790 million boe, the first-half result of 398.7 million boe represents just over half of the implied annual volume, putting CNOOC Limited broadly on the run rate required to achieve guidance if second-half operations remain stable.

The production target is backed by a RMB112–122 billion full-year capital-expenditure budget. First-half expenditure was approximately RMB62 billion, according to Reuters, placing spending around the midpoint of the annual programme on a simple half-year basis.

The bigger long-term issue is decline replacement. Offshore oilfields naturally lose output over time, meaning even a company reporting record production must continuously add projects, drill new wells and improve recovery from existing reservoirs simply to maintain the base before growth begins.

CNOOC Limited’s ability to hold all-in costs below US$30 per boe provides a considerable buffer. Low-cost barrels are economically resilient during weaker commodity cycles and become exceptionally cash generative when realised prices approach the levels reported during the first half.

How much of the record profit is being returned to shareholders?

The board declared a record interim dividend of HK$0.94 per share, implying an aggregate distribution of approximately RMB38.8 billion and a payout ratio of 45.2%. The distribution increased alongside earnings rather than forcing the company to choose between shareholder returns and its upstream investment programme.

That balance is central to the investment case. Oil producers can generate extraordinary cash during elevated commodity-price periods, but investors ultimately judge how much is returned, how much is reinvested and whether reinvested capital produces sufficient new reserves and production.

For CNOOC Limited, the current strategy remains expansionary. New offshore China discoveries, Brazil exposure, Indonesian acreage and multiple development projects suggest that management continues to favour production growth alongside distributions rather than shifting into a harvest-only model.

What is the latest CNOOC Limited share-price sentiment?

CNOOC Limited’s Hong Kong-listed shares closed at HK$25.12 on August 27, up 0.8% for the session. The stock was roughly 1.8% above its August 20 close of HK$24.66 and Reuters reported that the shares had gained about 17% during 2026, materially outperforming a broadly stagnant Hang Seng Index over the period cited.

The reaction around the results was not explosive, which is understandable because oil prices themselves contributed substantially to the earnings increase. Investors generally assign greater value to structural production growth and sustainable cost improvements than to profits generated purely by commodity-price movements.

CNOOC Limited nevertheless enters the second half with an unusually strong combination: record production, record interim profit, competitive unit costs and a record interim dividend. The principal variables are now external oil prices and internal execution against the 780–800 million boe production target.

If crude prices remain supportive while CNOOC Limited continues expanding volumes without materially increasing its US$29.70-per-boe cost base, earnings leverage could remain powerful. If oil prices retreat, the same low-cost structure becomes the defence mechanism that determines how much of today’s record profitability survives the cycle.
