Petrophysical Analysis Of Kadanwari-04 & Kadanwari-07, Lower Indus Basin, Pakistan

Abstract

In the current study, the main goal was to identify reservoir zones and to delineate the hydrocarbon potential for Kadanwari-04 and Kadanwari-07 wells. Kadanwari-04 and Kadanwari-07 wells are located at 69 27’88.83” E, 27 05’10.47” N and 69 25’74.95” E, 27 4’27.48” N respectively, in the Khairpur District of Sindh. Geologically, the research area is located in the extensional regime of the Lower Indus Basin, in the southeastern part of the Jacobabad and Khairpur highs, together known as Sukkur rift system. It has the Ornach-Nal fault and Aravalli range in the west and east, respectively. The features present are Mari Kandkot high and the Suleiman fold belt in the North. (Shah, MS., Stratigraphy of Pakistan) With previous consent from the Directorate General of Petroleum Concession (DGPC), the well logs of Kadanwari-04 and Kadanwari-07 wells were acquired from Landmark Resources (LMKR). Petrophysical evaluation of well Kadanwari-04 and Kadanwari-07 was carried out to highlight the reservoir area which included the selection of zone of interest followed by Log interpretation. The zones of interest in our study were marked in Lower Goru Formation in both wells. The petrophysical analysis of two marked zones of kadanwari-04 and kadanwari-07 respectively showed that there is 31.51%, 51.52%, 48.28% and 42.42% Vsh, 84.48%, 59.01%, 53.48% and 56.98% Sw and 17.51%, 48.74%, 46.51% and 43.02% saturation of hydrocarbons in Zones 1 and 2 in Kadanwari-04 and Kadanwari- 07 wells respectively.
