Petrophysical Analysis Of Qadirpur-03 & Qadirpur-11, Lower Indus Basin, Pakistan

Abstract

Qadirpur Gas Field, located in Pakistan, has been a significant contributor to the country's natural gas production. This thesis presents a comparative analysis of two key wells in the field, namely Qadirpur-03 and Qadirpur-11 located at 28°2'49” N 69°21'47” E, with a focus on reservoir characterization and production optimization. By utilizing well logs, production data, and geological information, this study aims to evaluate and compare the reservoir properties for both wells. The well logs of the Qadirpur-03 and Qadirpur-11 wells were acquired from the Directorate General of Petroleum Concessions (DGPC). Petrophysical evaluation of these wells was carried out to mark the reservoir area which included the selection of zone of interest followed by Log interpretation. The zones of interest of the study area were marked in Sui main limestone in both wells. Petrophysical analysis of two marked zones of Qadirpur-03 showed that there is 33.4% and 16.56% Vsh, 21.62% and 19% Sw 78.38% and 80.8% Sh and in Qadirpur-11 there is 64.1% and 16.01% Vsh,33.36% and 17.58% Sw 66.60% and 79.23% Sh in Zones 1 and 2 in Qadirpur-03 and Qadirpur-11 wells respectively. The value of Vsh is low and porosity is high which indicate it being producing wells.
