Abstract:
The basic objective of the study is to get preliminary understanding and knowledge of
the subsurface structures trend and stratigraphy of the cited area. Seismic interpretation
eventually resulted in outcomes as time and depth contour maps, which assisted to understand
the subsurface structures for further exploration.
Migrated seismic lines and Well logs of well AMIRPUR-01 of CHAKWAL area were
obtained from Bahria University, Islamabad.This dissertation contains the study of 2D
seismic reflection data interpretation of selected seismic lines of Chakwal, Northern Indus
Basin, Pakistan, for delineation of subsurface structures favorable for hydrocarbon
accumulation. Amirpur is situated in the Chakwal district of Punjab province. The data
comprised eight seismic lines, base map, and well tops of well Amirpur-01.
Four prominent reflectors (Blue, Red, Green and Purple) were marked on the basis of
their reflection, which represent Sakesar/Chorgali Formation and Khewra Formation
respectively. Reflectors were identified with the help of well top data, after conversion of
time to depth with the help of average velocity. Two-way time (TWT) from the seismic
sections and average velocities were used to create TWT and Depth Contour maps of Sakesar
and Khewra. In the end, by the examination of the maps, more study of the area is suggested
especially on the down thrown side, and for Khewra Formation.
