Abstract:
Seismic data interpretation and petrophysical analysis are the main tools in
petroleum exploration which are used to delineate subsurface geology and structural
geometries and to carry out hydrocarbon bearing capacity of the formations present in the
subsurface.
The main objective of this study is to delineate subsurface structural geometry and
to carry out petrophysical analysis of the selected zones. To achieve this objective six
seismic lines and well data were obtained from LMKR with the help of Kingdom Software.
Selection of control line, marking of horizons and their correlation as well as marking of
faults, followed by preparation of TWT contour maps and depth maps based on structural
interpretation, the overall structural geometry is a triangular zone with two positive
structures on both sides.
From the perspective of petro-physical interpretation, one reservoir zone have been
marked from Chiltan Limestone by using the data from ZIARAT-01 well. Zone of Chiltan
Limestone showed the 60% of hydrocarbon saturation, 18% volume of shale and 3-4%
effective porosity.
