Abstract:
The main purpose of the dissertation is to evaluate the structure and
hydrocarbon potential using seismic and well log data of Meyal area, Potwar subbasin,
Upper Indus Basin, Pakistan. Due to the collision of Indian plate and Eurasian
plate compressional forces are quite dominant in the Upper Indus Basin. As a result of
these compressional forces Meyal area thus consists of a pop-up structure which
facilitates the entrapment of hydrocarbons. The targeted formations were of Eocene
age. The horizons were marked after the generation of a synthetic seismogram on the
basis of their reflectivity coefficients. For structural enhancement, four migrated
seismic lines i.e. 97-MYL-04, 97-MYL-05, 97-MYL-07 (dip lines) and 97-MYL-13
(strike line), were used. Time and depth contour maps of three horizons, Kohat
Formation, Chorgali Formation and Sakesar Formation were generated which
confirmed the presence of a pop-up structure. Using the Allen diagram it has been
confirmed that the faults in the area are acting as a lateral seal for the reservoir.
Chorgali Formation has been evaluated for its hydrocarbon potential using the log
data which confirmed that it has good hydrocarbon potential. Reserves calculation
also revealed that there is sufficient amount of oil in place.
