2D Seismic Interpretation of Fazilpur Area, Central Indus Basin, Pakistan

Abstract

Structural analysis has been done using the 2D seismic data of the Fazilpur area, central Indus Basin Pakistan. Bahria University and the Directorate General of Petroleum Concession (DGPC) provided 2D seismic reflection data of well Choti-01 that was required for conducting this research. The Fazilpur area lies in the Punjab platform, Central Indus Basin, which is bounded by Sulaiman Depression on the east, Sargodha high on the north and Jaccobabad high in the south. The Punjab Platform dips westwards towards into the Sulaiman Fore deep. The field was established by OGDCL. For structural enhancement, four seismic migrated lines i.e. 954-FZP-05, 954-FZP-06, 954-FZP-09 and 954-FZP-10 were used. Time and Depth contour maps of the two horizons i.e. Habib Rahi Limestone and Sui Main Limestone were generated as both are reservoirs that identifies the structure of the area is regional monocline. Ghazij Formation was source for Habib Rahi while was seal for Sui Main Limestone. Sembar Formation act as a regional source rock in study area.
