PETROPHYSICAL ANALYSIS OF BALKASAR WELL OXY 1, UPPER INDUS BASIN PAKISTAN

Abstract

The main objective of this study is to find the hydro carbon potential of Balkasar Oxy 1 well, Upper Indus Basin Pakistan. About 105 kilometers southwest of Islamabad, in the Chakwal District, is where you'll find this well. Balkassar is situated in the Himalayan foreland fold-and-thrust belt's Potwar sub-basin. Its latitude is N 32° 55' 49.0008" and Longitude is E 72° 51' 20.0016". The OXY 1 well is drilled from Pliocene to Precambrian. Tectonically Balkasar Oxy 1 well lies at the south of MBT and north of SRT in Upper Indus basin. Sakesar limestone (Eocene) and Chorgali formation (Eocene) are the proven reservoirs of Balkasar Oxy 1 well. To evaluate the potential of these two reservoirs physical properties were calculated and analyzed using petrophysical analysis. Log data in this study used Gamma ray log, Neutron prosity log, Resistivity log, Caliper log, SP log. Five reservoir interval zones, three at the level of Sakesar limestone and two at the Chorgali formation were marked.
