Abstract:
This dissertation is based on the interpretation of 2D seismic data and the
petrophysical analysis of seismic lines in Ratana-03 well in the Upper Indus Basin,
Pakistan. Ratana is located in Pindighep Tehsil, one of the Tehsils in the district of
Attock. The data sets provided by DGPC include GR data sets, resistivity, SP and Sonic
data sets. Four reflectors (red, yellow, blue, orange) are marked, which represent the
Murree Group, Chorgali group, the Sakesar group and Salt Range. Reflectors were
identified by using well top data. After that converting the time into depth with the help
of average velocity. Afterwards petrophysical analysis was performed for
determination of average porosity, effective porosity, saturation of hydrocarbons and
saturation of water etc. Sakesar Limestone is considered as potential reservoir in the
area. Pop-up anticlinal structures were observed from time and depth surfaces of all the
four marked formations. The reflectors marked were of early Eocene, early Paleocene
and Jurassic age respectively.
