Murdi, Kufra & Basins, Onshore, Northern West Sudan
Opportunity to invest in under-explored basin
- Block 12 is located in the northwestern Sudan and covers an area of 128780.21 km2. The northwestern part of the Block lies over the southeastern flank of the Al Kufra Basin.
- The Block lies in the remote northwest Sudan, approximately 600km far from Khartoum the capital city. The block can be reached from the Nile at Ed Debba (760 km) or through Dongola International Airport (640 km).
- The Precambrian and Paleozoic geology of North Africa is remarkably consistent, reflecting its common geological history during most of the Phanerozoic period (e.g. Craig et al, 2006).
- The basins in Block 12 comprise a Paleozoic Basin represent the southeastern extension of the intra-cratonic sag basin referred to as the Kufra and Murdi Basins in Libya & Chad respectively and an undetermined basin in the southern part of the block (mostly in block 19).
- Many exploration activities have been done in the Block e.g Magnetic & Gravity survey, Surface Geological survey and 5204 km 2D seismic in addition to three wells were drilled in the block most of them located in the northern part, two wells encountered oil shows.
- Block 12 proved to be prospective with the encouraging results of fluid inclusions stratigraphy (FIS) in Sahara Well-1 & Tariq-001 and the oil extracted from Hadi-001 well (from fluid samples and cutting as well).
- Stratigraphic model and the petroleum system validated by the result of the three drilled wildcat wells.
- TOC and Rock Eval analysis indicates the presence of a very good source rock within the Early Devonian (Tadrart Fm), probably with a lacustrine origin. Silurian hot shale was not encountered in the three wells, as expected, because the wells are located on a paleo-high.
