Abstract:
The main purpose of this dissertation is to evaluate the structureand
hydrocarbon potential using seismic and well log data of Missa Keswal area
lying above soan syncline in North Potwar Deformed Zone, Upper Indus
Basin, Pakistan.The major tectonic structures in the Eastern Potwar include
anticlinal pop-up structures, synclines and overthrusted fault blocks. The
overall stratigraphy in the Potwar sub-basin ranges between Pre-Cambrian to
Pliestocene.The targeted Formations are of Eocene age. For structural
enhancement, five migrated seismic lines, 994-GNA-09, 994-GNA-10, 994-
GNA-14, 994-GNA-16 (dip lines) and 994-GNA-11 (Strike line) have been
used. Time and depth contour maps of two Eocene horizons, Chorgali
Formation and Sakesar Formation are generated which confirm the anticlinal
pop-up structure in the sub-surface. For petrophysical analysis one zone has
been marked at the level of Chorgali formation which infers that effective
porosity is 9% , Vsh is 22% and Sw is <45%.The full log data of Chorgali and
Sakesar Formation was not provided, if provided then good interpretation and
accurate reserve estimation could be done.
