Abstract: The Albertine Graben is a promising petroleum area in Democratic Republic of Congo and probably for the neighboring countries, with a length of several kilometers and a width nearly equal 60 km. Geological surface mapping has indicated that mature source rocks are guaranteed, hydrocarbons have been generated and migration has taken place as proved by several substantial oil seeps in the graben. Geological and geophysical mapping have demonstrated typical rift basin block faulting with sequences of reservoir quality sandstones exposed in the graben. The Albertine Graben is a Mesozoic-Cenozoic rift basin formed and developed on the Precambrian orogenic belts of the African Craton. The graben trends NE-SW through most of its length and forms the northern most part of the western branch of the East African Rift System. The effect of isostatic compensation of topography was calculated assuming the local compensation model of Airy-Heiskanen with the following parameters: crustal density, 2.67gcm 3 ; mantle density 3.19 gcm 3 ; water density 1.02 gcm 3 ; crustal thickness to sea level, 40 km.
