SOURCE ROCK EVALUATION OF ABU GABRA FORMATION IN AZRAG AREA –MUGLAD BASIN, KHARTOUM, SUDAN

Abstract

The Muglad basin is a large rift basin located in southwestern Sudan. At its nearest point, it lies approximately about 600km southwest of the city of Khartoum. It trends northwest-southeast and consist of a thick Mesozoic and tertiary continental syn-rift sequence buried by a Miocene-Recent post-rift sedimentary cover. These continental sediments comprise fluvial and lacustrine facies. Data from three boreholes, A1, B1, and C1 have been taken up for the present study. The geological associations, the Total Organic Content (TOC) and hydrocarbon generating potential values were studied to evaluate the source rock potential.   The evaluation revealed two wells; A1 and C1 to be potential as a source rock in oil and gas generation while the B1 well to be a poor source rock. Abu Gabra1 formation and Intra Abu Gabra formations of A1 well and Intra Abu Gabra 1formation and intra Abu Gabra 2 of C1 well are the most promising
