Petro-physical Analysis and Reservoir Characterization of Sara West-01 Well, Southern Indus Basin, Pakistan

Abstract

The purpose of entire study is to evaluate the
hydrocarbon potential via petro physical analysis and reservoir
characterization by utilizing well log data of Sara West-01,
Ghotki, Southern Indus Basin, Pakistan. The mentioned well is
exploratory and the Tullow Pakistan is the operator on this well.
For the evaluation of the potential of reservoir, different
equations have been used for the interpretation of different well
logs. Habib Rahi Formation and Sui Main Limestone reservoirs
of Cretaceous age of the area have been selected for the
evaluation of their respective petrophysical parameters and for
more distant computations by retaining the fact that they have
favorable ranges for saturation of water, porosities, and volume
of shale. Density porosity, Neutron porosity, and resistivity logs
do not show any direct identification for the presence of
hydrocarbons. Different suits of wireline logs have calculated
various petrophysical properties like porosity, resistivity, volume
of shale and fluid saturation. Although the formations have clean
lithologies with very little shaly content and good effective
porosity but the fluid saturation plots depicts Sara West-01 as
water wet well.
