Guyana EPA Waives EIA for TotalEnergies’ US$25mn Offshore Exploration

French energy major TotalEnergies has received a significant regulatory green light to proceed with a US$25 million exploration campaign offshore Guyana, marking a key step in expanding its footprint in one of the world’s premier oil basins.

The Environmental Protection Agency (EPA) has determined that the proposed 3D seismic survey project in the shallow-water Block S4 will not significantly affect the environment and is therefore exempt from the requirement to conduct a full Environmental Impact Assessment (EIA). This decision clears a major hurdle for the consortium led by TotalEnergies.

The project, scheduled to commence around August 2026, involves a comprehensive 3D seismic data acquisition program over the 1,788 square kilometer block. The survey is expected to last approximately 70 days. While exempt from an EIA, the project’s final approval is contingent upon the submission and acceptance of a project-specific Environmental Management Plan (EMP) to manage potential impacts like underwater noise and waste.

TotalEnergies operates Block S4 with a 40% interest, partnered with QatarEnergy (35%) and Petronas (25%). The consortium was awarded the block during Guyana’s competitive 2022 licensing round and signed the production sharing agreement in late 2025, paying a US$15 million signing bonus to the government.

Block S4 is located between 50 and 100 kilometers off the Guyanese coast in water depths ranging from 30 to 100 meters. This venture represents a strategic move for TotalEnergies to explore for “material, low-cost, and low-emission resources” in a prolific basin currently dominated by an ExxonMobil-led group.

The entry of TotalEnergies and its partners aligns with the Guyanese government’s goal of diversifying the players in its booming petroleum sector, which has seen production soar from zero to over 600,000 barrels per day in under five years. The initial exploration activities are expected to employ between 50 to 60 highly skilled personnel onboard the seismic vessel.
