Reservoir quality and facies modeling of the early Eocene carbonate stratigraphic unit of the Middle Indus Basin, Pakistan

Abstract: The early Eocene carbonate reservoir, Sui Main Limestone (SML), is the largest gas reservoir in Pakistan. In the Qadirpur area, more than 30 wells have been drilled, some of which have been declared dry or abandoned due to poor reservoir characteristics or facies variation. The aim of this work is to re-evaluate the reservoir characteristics and facies identification of Sui Main Limestone by using petrophysical analysis and rock physics modeling in the Qadirpur field in the Middle Indus Basin of Pakistan.

“…The petrophysical characterization of these carbonate rocks was extremely difficult due to heterogeneity and it exhibited a complex pore network. Based on the data obtained from well logs, these limestone reservoirs exhibited great variations in porosities ranging from 2-36%, with an average porosity of 22% [41]. In some places, these carbonates indicated microfractures and vugs, which resulted in high porosity values.…”

“…In some places, these carbonates indicated microfractures and vugs, which resulted in high porosity values. These microcracks were interconnected well, thus allowing the fluid to be produced more effectively [40,41].…”
