ExxonMobil has applied for environmental authorisation for a new 35-well exploration programme in Guyana’s Stabroek Block, signalling that exploration in the country’s main offshore oil province could continue well into the next decade.
According to Reuters, the application was submitted to Guyana’s Environmental Protection Agency (EPA), with the proposed campaign located about 193 kilometres, off Guyana’s Atlantic coast. The drilling programme is expected to run from 2028 to 2033, based on a project summary published by the EPA on June 14.
The proposed campaign would add to ongoing activity in the Stabroek Block and could help identify additional resources to support future development plans.
ExxonMobil’s Guyana portfolio already includes major developments such as Liza Phase 1, Payara, Yellowtail and later projects designed to lift production capacity from the block. The company’s own project overview shows how the Stabroek Block has moved from early exploration into a large-scale production base, supported by continued appraisal and development drilling.
A new 35-well campaign would extend that activity beyond the current wave of producing and sanctioned projects. It also suggests that ExxonMobil and its partners continue to see exploration potential in the block, even after years of discoveries and development.
The proposal would keep exploration activity moving alongside Guyana’s expanding oil production sector, as the country continues to balance development goals with environmental and regulatory considerations.
The application is still part of the environmental review process. Any drilling would depend on regulatory approval and the outcome of the assessment. For now, the filing gives a clear indication that offshore Guyana remains central to ExxonMobil’s exploration plans in the region.
