Stratigraphy and tectonic evolution of the oil producing horizons of Muglad basin, Sudan

Abstract EN

Muglad Basin is recognized to be a major part of Sudanese interior rift basins.

It trends northwest-southeast covering an area of over 1200km long and in excess of 300km wide.

The major segment of the faulted strata in this basin lies beneath the Late Tertiary sediments.

Rift tectonic phases have controlled the geological settings of the African rift basins and their associated sedimentary cycles.

Fractures of South African plate in early Mesozoic era was led to creation of deep troughs, this, together with sediment accumulations and faulting across the successively deposited beds formed structural and sedimentary conditions ideal for trapping of oil.Muglad trough was filled with non-marine sediments of upper Jurassic [1] derived from North African plate.

A generalized stratigraphic column and a modified map of Muglad basins illustrate: (1) The principal lihologies, maximum formation thickness, and producing formation of selected horizons from the Precambrian through Tertiary.

(2) The evolution history.
