Interpretation of 3D Seismic Data of Kaikang Area, Block6 Muglad Basin Sudan. (MUGLAD BASIN)

Abstract

Abstract Seismic interpretation is an art and sense mixing with high scientific knowledge. A complete interpretation requires the integration of geological, geophysical and engineering data and concepts. Consensus growing that the interpretation truly starts at the survey design phase, and continues up through processing. The main objective of this study is to look for drillable structure trap candidate to find out additional reservoir in Kaikang north throw the 3D seismic interpretation and make analysis of dry holes in Naha area, further more to investigate the main question why no oil in Bentiu formation in this area. Kaikang north located in North West of Muglad basin and to the South of the Fula sub basin in block 6 Sudan .The study area cover NAHA-3D466 km² within Kaikang North. Interpretation technique covers all the survey area, beside the analysis of some dry hole wells drilled by Petro Energy oil Company. The seismic data quality various from fair to poor, also there are 5 wells drilled in this area (Naha-1,Naha-2, Naha-3, Naha C-2, Kaikang 2 and Maha-1), the analysis of these wells show that the oil discovered in Aradiba formation, which is not consider as the main reservoir in Muglad basin. Naha-S-1produced Carbone dioxide (CO¬2), kang-1and kang-3, were failed due to non effective lateral sealing for Bentiu formation. Furthermore, the geological condition of Kaikang north is complicated, many faults were developed, Aradiba formation is deep and reservoir is poor but is consider as main target in this area. Up to now no oil was found in Bentiu formation which was an important play zone in Muglad basin and consider as main reservoir. So the Kaikang area was affected by tertiary strong movement, and three rifting phases, so that this problem made Buntiu formation too deep and must of deposition environment is lacustrine, and the reservoir property very poor so this is the main reason of no oil in Bintiu formation.
