Petrophysical Analysis of Sonro-04 well, Southern Indus Basin, Pakistan (P-0947) (MFN 4840)

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.
