Abstract:
Generally the aim was to understand the tectonics and geology of the Sujawal block along with the
interpretation procedure of migrated seismic sections and to check out the subsurface structures.
As the area is an extensional regime so faults were marked according to their type and structure
they are making. Formations were marked with the help of Well Dari-01. Interpretation was done
on the migrated seismic lines ASP88-232, ASP88-230, ASP88-228, ASP88-251 and ASP88-249 of
Sujawal block ,District Thatta, Sindh. This data was obtained from Land Mark Resources (LMKR)
by the permission of Directorate General of Petroleum Concession (DGPC) Islamabad. The
general dip direction in the project area of lines ASP88-232, ASP88-230, ASP88-228, is W -E and
hence the lines ASP88-251, ASP88-249, oriented NW-SE are regarded as strike lines. The
required information was in time domain which was helpful in the conversion of time into depth.
These calculations helped in subsurface interpretation of the area, which was the basic purpose of
this project. Two reflectors were marked named Top Near Lower Goru Formation and Top Near
Chiltan Limestone. Time and depth contour maps were generated which helped us to know the
basic mechanism of tectonic settings in the area. Furthermore various rock attributes were studied
at Top Near Lower Goru Formation to get hold of the reservoir potential.
