2-D seismic interpretation of Gujar Khan area and petrophysical analysis of Kal - 01 well (P-1134) (MFN 3998)

Abstract

Migrated seismic lines O-942-GJN-37, O-932-GJN-38, O-942-GJN-39, O-942-GJN-40 and O-952-GJN-53 of Gujar Khan area were obtained from Directorate General of Petroleum Concessions(DGPC) for seismic interpretation and Well Logs of well KAL-01 were obtained for petrophysical evaluation. The information required was given within the time section, which was helpful in the conversion of the time section into depth section. These calculations helped in subsurface interpretation of the area, which was the basic purpose of this project Three reflectors were marked ChorgaliFormation, Lockhart Formation and Khewra Sandstone. Faults were marked, and then time contour maps were generated. The major cause have been the thrust faults in the area thatform pop up structure. Petrophysical evaluation of KAL-01was carried out to highlight the reservoir area which included the selection of zone of interest followed by Log interpretation. The volume of shale, sand, porosity was interpreted. On the basis of Petrophysical evaluation it was noted that hydrocarbons and the reservoir of Cambrian (Khewra Sandstone) is of good porosity and is hydrocarbon bearing.
