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.
