TGS has completed the first phase of a project studying the geology and hydrocarbon systems of the East Russian Arctic. The project involved field studies and sample collection along the coastal areas of the Laptev Sea to better understand the petroleum geology of offshore sedimentary basins in the region. Over 1,000 samples were collected and will undergo laboratory analysis to provide new insights into topics like the tectonic evolution of basins, petroleum systems, source rocks, and depositional environments in this underexplored region. The results will be reported and used to improve assessments of hydrocarbon potential for the Siberian Arctic shelf. Future phases will expand fieldwork to other areas.
