2D SEISMIC DATA INTERPRETATION AND RESERVOIR EVALUATION OF MISSAKESWAL AREA USING PETROPHYSICS

Abstract

Two dimensional seismic interpretations have been carried out in MissaKeswal area located in Chakwal district of Punjab province, Pakistan to reveal the subsurface geology. The data used for this study was provided by department of Earth Sciences, the main purpose of this dissertation is the seismic structural interpretation of the MissaKeswal area in order to demarcate the probable zone for the accumulation of hydrocarbons. Seismic structural interpretation includes marking of reflector with the help of synthetic seismogram, fault picking, generation of polygon and time and depth contour map. To complete this dissertation SMT Kingdom 8.8 were used. The study area is located in Potwar Basin, popup anticline is major structure. Three seismic lines are been used:  994-GNA-09.sgy  994-GNA-11.sgy  994-GNA-15.sgy And the well-used is MissaKeswal-03. Prospect evaluation (including gridding, Time and Depth contouring and identification of structural traps) has been carried out using Kingdom suit of Software. Structural interpretation has identified pop-up and anticlinal structures favorable for hydrocarbon accumulation and is marked on seismic sections and time contour maps. The horizons are identified and named on the basis of well and generalized stratigraphic data.
