Seismic interpretation, petrophysical analysis and seismic inversion of Qadirpur area, central Indus basin, Pakistan (T-1553) (MFN 7083)

Abstract

Qadirpur area is located in province Sindh and this area of concession is operated by OGDCL. The area lies in Central Indus Basin. Sargodha High is present in north of area, Indian Shield is in the east, on west side is the marginal zone of Indian Plate and Sukkar Rift is in the south (Fig. 1.1). Upper Indus Basin is separated by Sargodha High and Pezu Uplift separates the basin in north (Kazmi and Jan, 1997). Area is approximately 820 sq. kilometers and the latitude and longitude of the area are of 27° 55’ to 28° 09’ N and 69° 11’ to 69° 31’ E respectively. In Sindh the area is in the districts of Ghotki and Jacobabad. When seen with geological prospect this area lies with Mari Kandkot High and some part of Middle Indus Basin of Pakistan. The total area is about 364 sq km that is intended for the detailed study by using 3D seismic data acquisition and processing. In past years of 1990, 1992 and 1998 round about 420 2D seismic lines of were acquired out by OGDCL. In 1990, gas was discovered in Eocene Limestone in Qadirpur area. Until today about 25 wells have been drilled for extensive development of the field. Sui Main Limestone is the main producer of gas in Qadirpur Gas-field area; hence most of the wellswere bottomed up to this Formation. On the other hand, Qadirpur-1 and QadirpurX-2 were drilled to Pab/Ranikot (Cretaceous /Paleocene) formations (Aamir et al., 2005).
