2D Seismic Interpretation and Reservoir Retimation of Zamzama Block Lower Indus Basin Pakistan

Abstract

A seismic final stack section HPK98A-31, HPK98A-32, HPK98A-33, HPK98A-34, HPK98A- 36 ZAMZAMA Block of Dadu Area was provided to me by the Earth and Environmental Sciences department of Bahria University Islamabad. The lines that were provided to me are dip and strike lines. The direction of the dip lines is East-West and the direction of strike lines is North-South. The root mean square velocity, Dix interval velocity, at different times was given. Five prominent reflectors are marked on the seismic sections on the basis of observed reflection events. The marked horizons show deformation in the area caused by compressional tectonics. ZAMZAMA thrust fault is marked in my portion of lines. A time section is produced from the seismic section using the SP points and the two-way-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 project the Well data of ZAMZAMA 02 was obtained from DGPC located in the Lower Indus Basin Sonic Log, Neutron Porosity Log, Density Log, Gamma-ray Log, and SP Log, were analyzed. These logs were used to determine Lithology, Volume of Shale, Petrophysical, and Seismic parameters, for Reservoir estimation.
