CNOOC LNG Supply Strategy, 1 MTPA Petronas Deal, and 9 South China Sea Projects (2021-2025)

LNG Supply Security, CNOOC 9 Domestic Projects and 2 Major Deals

In 2025, CNOOC executed a strategic pivot, shifting from a balanced import portfolio to an aggressive dual strategy of boosting domestic gas production and diversifying long-term international supply contracts to secure China’s energy supply ahead of an anticipated global LNG surplus. This proactive realignment aims to insulate China from geopolitical volatility and price shocks while positioning CNOOC to capitalize on the expected buyer’s market beginning in 2026.

• Before 2025, CNOOC‘s strategy involved a diversified mix of international suppliers and significant exposure to the LNG spot market. The U.S.-China tariff war, however, exposed the vulnerability of this approach, prompting a strategic shift toward more reliable, non-U.S. supply chains.
• The first pillar of the new strategy was a surge in domestic production. In 2025, CNOOC brought a record nine projects on stream in the South China Sea, including the major Shenhai-1 Phase II project, which is set to increase the field’s annual output to over 4.5 billion cubic meters.
• The second pillar involved securing long-term supply from new partners. This was validated by a long-term agreement with Malaysia’s Petronas for 1 million tonnes per annum (MTPA) and a five-year deal with the UAE’s ADNOC for 0.5 MTPA starting in 2026.
• This dual approach provides CNOOC with critical operational flexibility, enabling it to reduce reliance on imports during periods of high prices while using its expanded infrastructure to absorb cheap cargoes when the market is oversupplied.

China Dominates Global Natural Gas Demand Growth

This chart provides the fundamental context for CNOOC’s focus on supply security.

CNOOC 1 Major Cancellation, Upstream and Midstream Investments (2025)

CNOOC demonstrated strong capital discipline in 2025, prioritizing high-return domestic upstream and midstream projects while canceling a major, high-cost international decarbonization initiative that did not meet investment criteria. This focused allocation of capital underscores a strategy centered on immediate energy security and domestic infrastructure build-out rather than speculative or non-core ventures.

• A key investment was the completion of the Zhuhai LNG terminal Phase 2 project. The expansion added five 270, 000 cubic meter LNG storage tanks, one of the largest regasification capacity additions globally in 2025, significantly enhancing China’s ability to import and store LNG.
• Upstream investment was concentrated on bringing domestic fields online, most notably the Shenhai-1 Phase II natural gas project and the Xijiang Oilfields 24 Block Development Project, both located in the South China Sea.
• In a clear sign of its disciplined approach, CNOOC cancelled its investment in the Buzzard electrification project in the UK North Sea in August 2025. The company cited an inability to find an “investible solution, ” redirecting capital toward more certain, strategic domestic priorities.

North American LNG Export Capacity Set to Surge

The anticipated surge in North American LNG export capacity creates a more competitive, buyer-friendly global market. This market shift provides context for CNOOC’s strategic decisions, including cancelling less favorable contracts and re-evaluating its upstream and midstream investment portfolio to capitalize on new supply dynamics.

Asia and Middle East, CNOOC Secures Petronas and ADNOC LNG Deals

In 2025, CNOOC‘s partnership strategy centered on securing long-term LNG supply from politically stable, non-U.S. partners in Asia and the Middle East, directly mitigating geopolitical risk from trade wars and diversifying its sourcing portfolio. These agreements lock in crucial supply volumes ahead of an expected tightening of long-term contract availability, even as the spot market is projected to soften.

• The most significant agreement was a long-term deal signed in December 2025 with Malaysia’s Petronas for the supply of 1 million tonnes per annum (MTPA) of LNG, reinforcing a critical regional energy partnership.
• In April 2025, CNOOC‘s Gas and Power Group signed a five-year agreement to purchase 0.5 MTPA of LNG from the Abu Dhabi National Oil Corp (ADNOC) of the UAE, with deliveries scheduled to begin in 2026.
• These deals represent a deliberate pivot away from U.S. LNG, which is subject to tariffs and geopolitical friction, toward suppliers in Asia and the Middle East that offer greater long-term stability.
• Alongside these new agreements, CNOOC maintained its downstream petrochemical joint venture with Shell, signaling a continued, albeit selective, collaboration with Western energy majors in areas of mutual interest within China.

9 Projects in South China Sea, CNOOC’s Domestic Production Focus

CNOOC‘s geographic focus in 2025 decisively shifted inward to the South China Sea for production, while its procurement efforts targeted Southeast Asia and the Middle East, marking a significant strategic realignment away from reliance on U.S. and other less certain markets. This regional concentration enhances supply chain resilience by shortening delivery routes and reducing exposure to distant geopolitical flashpoints.

• The 2021-2024 period featured a more globally distributed sourcing strategy, with significant volumes coming from a wide array of countries including Australia, Qatar, and the United States.
• In 2025, domestic activity was heavily concentrated in the South China Sea, where CNOOC brought nine new production projects on stream, including the Dongfang gas fields and the Xijiang Oilfields 24 Block.
• Simultaneously, international procurement efforts were focused on securing deals with regional neighbors. The agreements with Malaysia (Petronas) and the UAE (ADNOC) exemplify this near-shoring trend for long-term contracts.
• This combination of a domestic production surge and regionalized procurement creates a strategic buffer, giving CNOOC greater control over its primary supply and reducing its dependence on long-haul LNG from the Atlantic Basin.

Commercial Scale, CNOOC’s Focus on Proven LNG Infrastructure

In 2025, CNOOC‘s initiatives did not involve new or pilot-stage LNG technologies; instead, the company focused exclusively on the commercial-scale deployment of proven upstream gas production and midstream regasification and storage infrastructure. This de-risked approach prioritizes rapid, reliable capacity expansion to meet pressing national energy security objectives over longer-term technological exploration.

• Throughout 2021-2024, while the global industry saw investments in emerging technologies, CNOOC remained focused on scaling existing capabilities. This strategy reached its apex in 2025.
• The completion of the Zhuhai LNG terminal Phase 2, featuring massive 270, 000 cubic meter storage tanks, represents an expansion of existing, proven regasification and cryogenic storage technology, not an adoption of a new one.
• Similarly, the successful development of deepwater gas fields like Shenhai-1 Phase II leverages established offshore drilling and production techniques that are well-understood and reliable, ensuring production targets are met without technological risk.
• This focus on mature, at-scale technology demonstrates that CNOOC‘s primary objective for the period was achieving immediate, large-scale increases in gas supply and import capacity, a tactical decision to favor volume and reliability over innovation.

CNOOC LNG Strategy SWOT Analysis (2021-2025)

CNOOC‘s 2025 strategy leveraged its strengths in domestic production and state backing to secure long-term energy supply, but it also increased the company’s exposure to geopolitical risks from its Russian dealings and potential market risks if spot prices fall dramatically below its new contract prices.

• The company’s core strength remains its government mandate and deep technical expertise in offshore exploration and production, which enabled the successful launch of nine domestic projects in 2025.
• A key weakness is the trade-off between securing long-term supply and exposure to a falling spot market, which could make its new contracts with Petronas and ADNOC appear expensive post-2026.
• The primary opportunity lies in using its expanded infrastructure and diversified contracts to become a dominant buyer and price-setter in the anticipated LNG glut.
• The most significant threat is the potential for Western sanctions or diplomatic pressure resulting from its continued offtake of sanctioned LNG from Russia’s Arctic LNG 2 project.

Post-2025 Outlook, CNOOC’s Balancing Act with New LNG Contracts

Looking ahead, CNOOC‘s primary strategic challenge will be to balance its new long-term supply commitments with the opportunistic procurement of cheaper spot cargoes expected in the post-2026 oversupplied market. Its success will depend on its ability to leverage its vast new storage infrastructure to optimize its portfolio.

• If global LNG spot prices fall significantly below its new contract prices from Petronas and ADNOC, watch for CNOOC to use its massive storage capacity at the Zhuhai terminal to absorb cheap spot cargoes for strategic reserves, which could impact its scheduled offtake of contracted volumes.
• If Western sanctions tighten on entities dealing with Russian LNG, these could be happening: CNOOC may face restrictions on its access to international finance or technology, which could complicate its joint ventures and partnerships with Western majors.
• The smooth commencement of the ADNOC supply in 2026 will be a key signal to watch. A successful start will validate CNOOC‘s strategy of diversifying into the Middle East and will likely encourage similar deals with other regional producers.
• Watch for further investment in domestic natural gas production and infrastructure, as the 2025 strategy proved highly effective in bolstering China’s energy security, making it a repeatable model for the company.
