2D SEISMIC INTERPRETATION AND PETROPHYSICAL ANALYSIS OF MINWAL OIL FIELD, UPPER INDUS BASIN, PAKISTAN

Abstract

Minwal block resides in the southeastern part of the Potwar sub-basin i.e., the area under study. With reference to tectonics, the area lies in the compressional regime. The Sakesar Limestone in this area is acting as a reservoir for hydrocarbons. Aiming to determine the hydrocarbon potential of Sakesar Limestone, we utilized wireline log data of two wells for reservoir rock analysis. Furthermore, for the representation of subsurface structure of Minwal block, we used 2D seismic data. Afterwards, the well and the seismic data were tied in order to pick reflectors on the seismic, which are displaced by frontal and back thrust. Structure maps for the picked area were constructed, with respect to time and depth. We observed the triangular structure from the depth structure map, oriented from NW to SE.
