CGG GeoConsulting’s NPA Satellite Mapping group has launched the multi-client EARS BasinMap for exploration de-risking across East Africa, from regional-to-prospect or play scale

The EARS BasinMap provides an entirely new 1:200,000 scale geological map and database of the East African Rift System (EARS) and integrates structural history, drainage analysis and sediment provenance of the region. Compiled by interpretation of satellite optical imagery and topographic data, the database extends across approximately 2.5mn sq km of East Africa including Kenya, Uganda, Tanzania, Rwanda, Burundi, Malawi and parts of Ethiopia, Mozambique, Zambia and the Democratic Republic of Congo.

The application allows new ventures and exploration teams to perform regional screening to rapidly gauge and understand the structural dynamics of ongoing rifting, and predict the location of favourable sediment sequences with high reservoir potential.

Across the under- and unexplored rift basins, where exploration data quality and quantity are limited, the EARS BasinMap provides a regional analysis of the timing and history of regional fault movement, uplift and erosion, which control sedimentation and accommodation space within the basins. The combined elevation data and map data provide valuable insight on geological evolution, source-to sink depositional systems and reservoir quality.

The EARS BasinMap’s geological database can be accessed through NPA Satellite Mapping’s proprietary ArcGIS Onshore Analyst Tool (OAT), which allows user-driven queries of thematic datasets, encompassing fully referenced lithologies, local names, stratigraphic age, and type and timing of structures. The EARS BasinMap is available for licensing for either the entire East Africa region or cropped large sub-regions.
