Abstract:
A seismic final stack section comprising of HPK98A-30, HPK98A-31, HPK98A-32,
HPK98A-33, HPK98A-34and HPK98A-36 of ZAMZAMA Block of Dadu Area was provided
for this research by the Department of Earth and Environmental Sciences, Bahria University
Islamabad through Directorate General of Petroleum Concessions (DGPC). The lines provided
are dip and strike lines respectively which trend East-West and North-South. The root mean
square and Dix interval velocities at different times were given. Five prominent reflectors were
marked on the seismic sections on the basis of observed reflection events. The marked horizons
show deformation in the area caused by compression. Based on the reflectors trend, a thrust fault
is marked within the dip lines.
A time section is produced from the seismic section using the CDP points and the twoway-
times (TWT) of the reflectors and fault. These average velocities are then used to find the
depths of the formations for the Depth Section.
In this research study the Well data of ZAMZAMA 03 was obtained from DGPC located
in Lower Indus Basin. Sonic Log, Neutron Porosity Log, Density Log, Gamma ray Log, SP Log
and PEF were analyzed for petrophysical analysis. The logs were used to determine lithology,
volume of shale, petrophysical and seismic parameters for reservoir estimation.
