Abstract:
Minwal block lies in the southeastern part of Potwar sub-basin. 2D seismic
data has been used for the delineation of the subsurface structure of Minwal block and
for the reservoir rock analysis, wireline log data of two wells have been utilized.
Tectonically the area lies in the compressional regime which is the result of Indian
and Eurasian plate collision. The well and the seismic data are tied for picking the
reflectors on the seismic. These reflectors are displaced by two reverse faults. Time
and depth structure maps have been created for picked horizon. The depth structure
map constructed shows triangular structure. The orientation of this triangular structure
is from SE to NW. Reverse faulting and triangular structure are providing the
structural trap for the accumulation of hydrocarbons. Attribute analysis confirms the
presence of sweet spots which is the indication for the presence of hydrocarbons. In
order to determine the potential of hydrocarbons in the Sakesar Limestone which is
acting as a reservoir in the study area, petrophysical analysis has been done which
showed 60.55% hydrocarbon saturation. It indicates that the formation has good
reservoir potential.
