Abstract:
The main objective of the study is to evaluate the petrophysical properties of
Sonro-04, Southern Indus Basin, Pakistan. This is located in Hyderabad district, Sindh
about 1395 km south of Islamabad having coordinates longitude 68° 41’ 56.46” E and
latitude 25° 07’ 38.32” N. The well under study lies in Thar platform which is bounded in
north east by Jacobabad and Mari Kandhok highs, in south by Arabian Sea, in west by
Karachi trough and in northwest by Kirthar depression.
Petrophysical evaluation of Sonro-04 was carried out to highlight the reservoir
area which included the selection of zone of interest followed by log interpretation. The
volume of shale, porosity, water saturation and hydrocarbon saturation were interpreted
by using different tools like gamma ray tool, porosity tool, density tool, resistivity tool.
On the basis of petrophysical evaluation Lower Goru Formation (B Sand) is acting as a
reservoir, which has volume of shale, effect porosity and saturation of hydrocarbon is
29.56%, 16.36% and 51.47% respectively.
