2D Seismic Data Interpretation and Petrophysical Analysis of Dhulian Field, Upper Indus Basin, Pakistan (P-1172) (MFN 5555)

Abstract

The main purpose of the dissertation is to evaluate the structure and hydrocarbon potential using seismic and well log data of Dhulian area, Pakistan. Dhulian area lies in district Attock, near PindiGheb, Upper Indus Basin Pakistan. The Potwar sub-basin is situated at the northern margin of the Pakistan in the western foothills of Himalayas. It comprises of the Potwar plateau, the Jhelum plain and the Salt Range. The Dhulian structure is thought to be enriched by potential hydrocarbon, trapped up dip from the depo-centre of Soan depression. The targeted formations were of Eocene, Paleocene and Permian age. For structural enhancement, five migrated seismic lines i.e. PDK-102, PDK-103, PDK 104 (dip lines) and PDK-112, PDK-113 (strike line) were used. Time and depth contour maps of four horizons, Chorgali Formation, Sakesar Formation, Lockhart Formation, Datta Formation were generated which confirmed the Scissor anticline structures in the subsurface. For Petrophysical analysis one zone has been marked at the level of Sakesar Formation whereas one zone has been marked at the level of Lockhart Formation.
