Petrophysical Analysis of Kadanwari Well No 10 & 11, Middle Indus Basin, Pakistan

Abstract

The main objective of research is to evaluate possible reservoirs in Well # 10 & 11 of Kadanwari gas field, which lies in Middle Indus basin, Pakistan. The said objective has been achieved by the petrophysical characterization of reservoir zones using wireline logs. The methodology adopted to achieve the goal includes; Quality Check of the data set (complete suite of wireline logs), correlation of curves of different logs to demark the possible reservoir zones , measurement and computation of shale volume using gamma ray log, Resistivity of water using SP log, Porosity measurement by all porosity tools "neutron, Density and Sonic", Resistivity of invaded as well as un-invaded zones for the calculations and derivation of true resistivity and the saturation measurements using Archie's saturation equation. The results of above mentioned analytical work done answered in positive, the zones marked through correlation of data show very good to fair hydrocarbon potential on the basis of evaluated clay volume, porosity and saturation component.
