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%).
