EARS BasinMap

Contiguous geology for frontier explorationThe EARS BasinMap delivers a unified view of the structural and sedimentary evolution of East Africa’s rift basins, for exploration de-risking from regional-to-prospect or play scale, enabling Exploration and New Ventures teams to make informed decisions about where to focus.

What is EARS BasinMap?•The first contiguous, unified 1:200,000 scale geological map and

database of East Africa (covering Kenya, Uganda, Tanzania, Rwanda, Burundi, Malawi and parts of Ethiopia, Mozambique, Zambia and the Democratic Republic of Congo)

•Compiled through expert interpretation of optical satellite imagery and topographic data

•Integrated overview of structural history and drainage analysis (source-to-sink)

Benefits•Provides a consistent overview of the geology of the East African

Rift System, a region where exploration data consistency, quality and quantity are a significant challenge

•Enables regional screening by New Ventures and Exploration teams to rapidly gauge and understand structural dynamics of ongoing rifting

•Supports efforts to identify locations of favourable sediment sequences with high reservoir potential

•When coupled with Seep Explorer, CGG’s highly rated on- and offshore seepage database, clients can decrease structural, reservoir and source risk in this developing hydrocarbon province

The EARS BasinMap builds on a thorough geological understanding of East Africa gained by our team of structural geologists after a decade of working in the region (including field campaigns and integration of satellite data with seismic and potential field data).
