Abstract:
The study area Zamzama belongs to BHP. The research area is about 120 sq. Kms includes the well logs of Zamzama well 3. The area has been identified as a compressional regime and is characterized by a major Kirthar Fold Belt (KFB). A study was carried out to highlight the reservoir area of the Zamzama well which included the selection of the zone of interest followed by well log interpretation. The volume of shale, sand, porosity, and saturation of water were interpreted followed by the preparation of isopach maps and well correlation between different wells. The porosity map of Pab Formation was also generated in the study area. A field study was also included in this dissertation in the Mughal Kot area in order to observe different features of the source Sembar Formation and Reservoir Pab Formation. On the basis of the Petrophysical Evaluation, it was noted that the reservoir has a mud-dominated facie having porosity but low permeability. The hydrocarbon saturation is also low which further makes the well uneconomical and hence it was abandoned. On the basis of the Petrophysical Evaluation, it was suggested that the well may be drilled further for possible hydrocarbon exploration as in the surrounding area deeper horizon i-e Goru Formation is producing hydrocarbons.
