SEISMIC INTERPRETATION OF KADANWARI AREA AND PETROPHYSICAL ANALYSIS OF ADIANI 01, LOWER INDUS BASIN, PAKISTAN

Abstract

The document discusses the geology and tectonics of study area that lies in Kadanwari fields which is a Horst and Graben structure. Geographically, this lies in Tajjal area, Khairpur district, Sindh, Pakistan. Tectonically, the area lies in eastern Jacobabad – Kirthar Horst of Lower Indus Basin Pakistan. The document focuses on the 2D seismic interpretation of the study area to investigate for the petroleum system and the structures capable of hydrocarbon accumulation with the help of available seismic lines. The subsurface image of the area confirms and showsstructures of Horst and Graben. The results are further elaborated in terms of time and depth maps of the study area. The document also discusses the petrophysical analysis of the study area on the basis of well log data available for Adiani-01 well drilled in that area. The main focus of petrophysical analysis is the evaluation of the primary reservoirs in the study area namely Lower Goru Formation and Sui Main Limestone of late Eocene age in terms of three main reservoir characteristics namely characteristics i.e. porosity, saturation of hydrocarbons and shale content of the reservoirs in the study area. The whole interpretation is expressed in terms of graphs that depict good effective porosity conditions, less shale content and considerable hydrocarbon saturation in that area.
