ExxonMobil Guyana Limited plans to establish a services agreement for offshore geotechnical investigations and environmental baseline surveys in Guyana’s deepwater acreage.
The operator is seeking suppliers capable of delivering a full suite of geotechnical and environmental services across prospective project sites. The scope includes borehole drilling to acquire 30 m to 40 m of geotechnical definition with in situ testing, shallow coring ranging from 0.5 m to 9 m, and box coring of up to 1.0 m.
The public request for information (RFI) said the work will be carried out offshore Guyana in water depths of up to 3,000 metres (m).

Environmental sampling and measurements form part of the scope, alongside the development of operations and field reports based on acquisition results.
Suppliers are also expected to manage logistics for exporting and transporting samples to designated laboratories and to develop and execute laboratory testing programs.
The RFI outlines requirements for processing and interpreting geotechnical data and laboratory results, as well as producing geotechnical interpretation reports. These include pipe–soil interaction and riser–soil interaction studies, slope stability analyses, environmental baseline survey reports, and an integrated site characterization report.

ExxonMobil has already contracted Norway-based Shearwater GeoServices to conduct a six-month 4D ocean bottom node survey in the Stabroek Block. The program is designed to capture time-lapse changes in geophysical properties to support development drilling.
That survey followed an earlier 4D seismic contract with PGS.
The company is progressing plans for five additional offshore oil developments, with total production capacity expected to exceed 1.7 million barrels per day by 2030.
