Abstract
Hydrocarbon exploration over the Ugandan side of the Albert Graben is still within main operators’ program. The 2019 second Ugandan Bid Round reoffered several blocks that requires further evaluation of the proven petroleum system. In these areas, exploration is mainly driven by potential fields methods and sparse 2D seismic data, locally complemented with precious 3D seismic data. Hence, integrating of surface and subsurface data at regional-scale in an overall source-to-sink study remains crucial (i.e. detrital geochemical studies, tectono-stratigraphic analyses associated to an age model built up by combining sedimentological and biostratigraphical outcrop studies). This work illustrates an integrated update of the sedimentary basin infill of Albert Graben developed thanks to multi-disciplinary regional synthesis. The results can be used for defining the reservoir-presence risk as well as the distribution of the source rock-type (terrigenous to lacustrine end-members) expected in the deepest and potentially matured part of the basin for petroleum system modelling.
