PETROPHYSICAL ANALYSIS OF WELL NARA-01, LOWER INDUS BASIN, PAKISTAN

Abstract

The objective of this study is to determine the hydrocarbon potential of Nara- 01 well using wireline logs. Nara-01 well is located in Miano gas field block 2. Miano Gas field is located in the Thar Desert, in the Sukkur region. Log data used in this study includes the Gamma-ray log, Gamma ray Neutron tool, Resistivity log, Caliper log, and SP log. The borehole profile of the zones of interest was good. Lower Goru acting as a reservoir. There were four zones had been marked. One zone in B sand, two zones in C sand, and one in D sand. The present study showed that the volume of clean was about 67.13% in D sand, 59.57% in C sand, 70.27% in C sand, and 69.41% in B interval. The total porosity in D sand was 12%, 14.68% in C sand, 11.71% in C sand, and 9.09% in B sand while effective porosity was 4.20% in D sand, 5.36% in C sand, 4.06% in C sand, and 6.03% in B sand. Saturation of water was 59.64% in D sand, 59.55% and 52.85% in C sand, and 73.85% in B sand which showed that the zone of interest is a hydrocarbon-bearing zone as compared to water. Petrophysical analysis showed that prospect zone has clean lithology and good effective porosity. Therefore, petrophysical analysis reveal that in Nara-01 well, Lower Guru Formation is the best zone regarding hydrocarbon potential.
