Petrophysical analysis of Qadirpur well-03, central Indus basin, Pakistan (P-0889) (MFN 3981)

Abstract

The main objective of this dessertation is to evaluate the hydrocarbon potential of the well Qadirpur-03 of Qadirpur Gas field. Geographically Qadirpur-03 well is located at 28° 05" 15.10' N and 69°20"40.28' E at at a distance of 8 km from Ghotki in Sindh Province. Tectonically Qadirpur Gas field lies at the South Eastern boundary of Sulaiman foredeep in Central Indus basin. Sulaiman sub-basin contains 14 gas and condensate fields with proven reservoirs of Eocene carbonates. Habib Rahi limestone of Kirthar Formation (middle to late Eocene) and Sui Upper limestone (lower Eocene) are the proven reservoirs of Qadirpur well-03 which is producing 526 MMscf gas per day.Toevaluate the potential of these two reserviors physical properties were calculated and analysed using petrophysical analysis. Four zones, two at the level of Habib Rahi limestone and two at Sui Upper limestone were marked. Out of four zones, zone 3 ranging from 1222-1225m of Sui Upper limestone comes out to be potential zone with good effective porosity 23.22% due to presence of vuggs. Although total thickness of this zone is less than other zones but it is showing high hydrocarbon saturation of 72.2% which is economical.
