Simba holds a 100 % interest in the Production Sharing Contract (PSC) for Block 2A, onshore Kenya. Block 2A (7,801.72 km2) overlies the southern tip of the Mandera Basin while the southwest corner of the block extends into the Anza Basin. Block 2A also has excellent potential for significant oil and gas discoveries.
Simba Block 2A, Passive Seismic Results, Kenya
The original undertaking was to investigate and ascertain the hydrocarbon potential at the Company’s three targets (P1, P2, P3) by first employing a block survey using passive seismic to confirm or identify areas of hydrocarbon potential to be followed up with 2D seismic for structure definition.
This first phase of passive seismic has confirmed P1 to be comprised of two distinct and sizeable leads with excellent hydrocarbon response lying east and SSE of the city of Wajir. The first lead in P1 with an area of 29km² demonstrates the highest level of hydrocarbon seismic energy interpreted amongst all seven potential leads identified by the survey; the second and likely related lead is over 100km² in size with good response for hydrocarbon potential and lies from 8km to 20km+ to the SW.
The Mandera Basin is Permo-Triassic to Tertiary in age with a sediment thickness of 10,000 meters. Potential source rock interval is mid Jurassic-Lower Cretaceous and comparable with the larger Mandera-Lugh basin in Ethiopia and Somalia
Only four wells have been drilled in the Mandera basin with oil shows encountered at 40-44m in the Tarbaj stratigraphic well drilled by Total
In the Anza basin lower Cretaceous reef structures have been mapped with a potential reservoir thickness of 300m-500m. Source rock is likely Lower Cretaceous. The eleven wells drilled in the Anza Basin have encountered oil shows and/or gas shows
Present 2D seismic coverage, although regional in nature, identified numerous structures and a major stratigraphic pinch-out. The limited seismic coverage available indicates a stable stratigraphic sequence with some very good exploration leads
Remaining of exploration interest to the Company is the flank of the basement high structure where two AMOCO wells drilled in 1987 (ELGAL#1 to 1,280 meters in Permian Karroo and ELGAL#2 to 1,908 meters in Triassic Karroo) were plugged and abandoned as no reservoir rocks were encountered
The area of the block overlying the Mandera basin is of particular interest as the analysis of the oil from the seeps at Tarbaj although severely biodegraded indicate a source rock maturity for the Mandera basin which is well within the oil window
The Company will immediately begin re-interpretation of all available existing data, as well as initiate baseline environmental work, to support the design and planning of a new seismic acquisition program.
