Regulatory documents in Guyana indicate that Exxon Mobil is seeking environmental approval for a significant offshore drilling program that could deepen its presence in one of the world’s most closely watched oil frontiers.

According to the country’s environmental authorities, the company has submitted an application for authorization covering a 35-well exploration campaign in the Stabroek Block, located roughly 120 miles (193 km) off Guyana’s Atlantic coastline. The filing is currently under review by the national environmental regulator.

The plan, as outlined in official documentation, sets out a multi-year operational window. A project summary published by the Environmental Protection Agency (Guyana) on June 14 states:
The campaign is expected to run from 2028 through 2033, according to a project summary published by the EPA dated June 14.

If approved, the exploration activity would span five years, reflecting the scale and long-term nature of offshore development in the deepwater basin. The Stabroek Block itself has become a major focus of global energy investment in recent years, with multiple discoveries already transforming Guyana into one of the fastest-growing oil-producing regions.

The proposed 35-well program suggests continued appraisal and exploration efforts aimed at identifying additional reserves and supporting future production planning. Environmental authorization is a mandatory step before any offshore drilling campaign can proceed, particularly in sensitive marine zones such as those off Guyana’s Atlantic coast.
