ExxonMobil Guyana Limited will continue its Ocean Bottom Node Seismic Surveying operations in Guyana’s Exclusive Economic Zone until December 31, 2025. The activities are being conducted at the Stabroek Block where the company is the operator.
According to a notice issued by the Maritime Administration Department (MARAD), the operation will involve four vessels, each displaying the international signal for ships engaged in seismic activities: the Seismographic Research Vessel Amazon Warrior, Seismographic Research Support Vessel Astra-G, Seismographic Research Support Vessel Mariska-G, and the OCV Island Pride.

The survey area lies approximately 78.76 nautical miles (145.87 kilometres) from Guyana’s coast and spans 1550.89 square nautical miles (5,319.40 square kilometres). It is defined by ten coordinates, all referenced to WGS 84 (Zone 21).
ExxonMobil awarded Norwegian seismic company Shearwater GeoServices a contract to conduct a six-month 4D ocean bottom node survey offshore in the Stabroek Block. The 4D survey complements ExxonMobil’s development drilling efforts in the Stabroek Block and improves understanding of offshore hydrocarbon reservoirs by capturing time-lapse changes in geophysical properties.
ExxonMobil has already contracted PGS for a previous 4D seismic survey in Guyana. The company is advancing plans for five more development projects in the country, aiming for a production capacity exceeding 1.7 million barrels per day by 2030.
