Abstract:
The objective of this study is to find the hydrocarbon potential of Missa Keswal- 03 well. Upper Indus Basin, Pakistan. In Missa Keswal-03, drilling has been done up to Khewra Sandstone of Early Cambrian age.
Missa Keswal oil field is situated around 60km from Islamabad in the eastern side of Potwar basin. On surface, it is an anticline thrusting in SW-NE direction.
Data which is used in this study are LAS files and well tops of well-03 of Missa Keswal. LAS files of this wells only contain the complete log curves of Chorgali, Sakesar and Nammal respectively.
Log used are Gamma ray log, SP log, Caliper log, Resistivity logs, Neutronporosity log. Methodology adopted for petrophysical analysis included interpretation of log curves, calculation of volume of shale, estimation of porosities, and computation of resistivity of water by Pickett plot and hydrocarbon saturations by utilizing Archie’s equation.
Two prospect zones in each of formations i.e., Chorgali Formation and Sakesar Limestone have been marked. Petrophysical analysis indicated that Chorgali and Sakesar have fair hydrocarbon potential.
