Attributes of potential hydrocarbon reservoir sandstones in the sokoto sector of the iullemmeden basin: An outcrop analogue study
The Sokoto area of Nigeria is the southeastern margin of the very extensive (ca. 1 million km2) Iullemmeden Basin – an intracratonic depression in the Precambrian Basement Complex. The basin fill succession consists of the Late Jurassic continental facies and Cretaceous marine deposits topped by Mid-Paleogene continental facies. Impressive outcrops had spurred the search for petroleum in early colonial time but the poor showing of the earliest boreholes discouraged the efforts.
