ExxonMobil Guyana Limited (EMGL) is pressing ahead with environmental and geophysical survey activities in the Stabroek Block as part of its long-term development plans.
According to the Maritime Administration Department, EMGL’s Environmental Sampling Survey will continue until December 31, 2025. The operation will utilize the Offshore Support Vessel (OSV) Doña Jose II.

The sampling zone is located approximately 95.99 nautical miles (177.89 kilometers) off Guyana’s coast and covers an area of 515.81 square nautical miles (1,769.17 square kilometers).
Separately, ExxonMobil began Autonomous Underwater Vehicle (AUV) survey operations on August 20, 2025. That exercise, using the vessel ARMADA 7807, is expected to conclude on September 30, 2025.
In addition, ExxonMobil has contracted Norwegian seismic company Shearwater GeoServices to conduct a six-month 4D ocean bottom node survey in the block. The survey is designed to capture time-lapse changes in geophysical properties, enhancing understanding of hydrocarbon reservoirs and supporting ongoing development drilling.

The new award follows an earlier 4D seismic contract with PGS, underscoring the operator’s push to deploy advanced imaging technologies offshore Guyana.
ExxonMobil is simultaneously advancing plans for five additional oil developments in the country, targeting a combined production capacity of over 1.7 million barrels per day by 2030.
