Petrophysical analysis of Zamzama well-05, southern Indus basin, Pakistan (P-1577) (MFN 3990)

Abstract

The main purpose of the study is to evaluate hydrocarbon potential of well Zamzama-05, which is located in Zamzama gas field, District Dadu Sindh province Pakistan. Zamzama-05 is a production well producing gas at a level of Dunghan Limestone, which is lying at a depth of 2773m having 406 m thickness. For detail delineation of reservoir, petrophysical analysis is carried out to evaluate the physical properties of Dunghan Limestone, which is further divided into three zones ranging from (2778m-2800m) zone1, (3030m-3040m) zone2, (3090m-3100m) zone3 respectively. Out of three zones, zone 3(10m) is consider as a potential zone having total Porosity (4.7%), effective porosity (3.9%), water saturation (12.565%), hydrocarbon saturation (87.434%).
