This study pertains
to the evaluation of shale gas and rock physics properties of this area with
respect to its total organic content of Sember Formation, Khiproarea, Pakistan.
We use well logs data for this study. The Khipro area is prominent in the Lower
Indus Basin for its hydrocarbon (oil and gas) structural traps. In shale gas
evaluation, TOC of Sember Formation is estimated. The analysis has been done
with the help of the wire line data of the well Bilal North-01. The presence of
shale gas in the study area is analyzed with the help of different techniques.
Rock physics and petrophysical analysis have been done in order to get the
properties of the area related to the shale gas evaluation.
