US supermajor ExxonMobil has submitted environmental plans calling for the drilling of up to 35 new wells in the prolific Stabroek block offshore Guyana.

The proposed campaign is expected to begin in the third quarter of 2023 and be completed in late 2028, as the company plans to search for additional hydrocarbons on top of the 11 billion barrels of oil equivalent in recoverable resources discovered so far in Stabroek.

“While some of the 35 wells will be drilled for exploration purposes, it is also possible that some of the wells may be drilled as appraisal wells within the proximity of previously drilled exploration areas,” ExxonMobil said in the 41-page plan.
