Longer Leads, Increasing Complexity in Oil and Gas Field Development

Analysis of the Global Oil and Gas Extraction Tracker (GOGET) reveals that oil and gas fields now take significantly longer to come online than in the 1960–1980 period, with 2025 startups averaging 15.1 years. This increase is driven by the depletion of easily accessible fields, forcing companies to target technically challenging 'hard-to-recover' reserves, such as ultra-high pressure '20K technology' fields in the U.S. Gulf of Mexico and remote Arctic projects in Russia. Additional delays stem from reservoir compositions (e.g., sour gas), ecological risks in protected areas, and more stringent environmental regulations, such as the UK's 2025 guidance on scope three emissions. The report argues that these long lead times increase the risk of creating stranded assets and locking in production that contradicts global climate targets to limit warming to 1.5°C.

• The time required for oil and gas fields to begin production has increased dramatically, with 2025 startups averaging 15.1 years from discovery, compared to an average of 4.9 years during the 1960–1980 period.
• Increasing technical complexity is a primary driver of longer lead times, as companies move toward 'hard-to-recover' reserves, including ultra-deepwater, remote locations, and ultra-high pressure reservoirs.
• Reservoir composition and ecological sensitivities further delay projects; sour gas reservoirs present health and equipment risks, while projects in protected areas face biodiversity concerns and civil society opposition.
• Regulatory environments are becoming more stringent, specifically regarding environmental impact assessments, which can extend permitting periods and lead to legal challenges.
• Infrastructure scarcity in frontier basins like Cyprus and Namibia slows development, whereas established regions like Guyana have seen faster turnarounds due to rapid project deployment.
• The long development timelines create a high risk of 'stranded assets' and lock in fossil fuel production that is incompatible with the 1.5°C warming limit.
