2D SEISMIC DATA INTERPRETATION OF SINJHORO AREA AND PETROPHYSICAL ANALYSIS OF CHAK 66-01 WELL, LOWER INDUS BASIN, PAKISTAN

Abstract

This research paper focuses on implementing seismic interpretation and petrophysical analysis to determine the Sinjhoro region's subsurface structural analysis and hydrocarbon potential in Southern part of Lower Indus basin. The data used in the study include three dip lines and two strike lines. The well log data was also acquired as part of the petrophysical evaluation. On the seismic data interpretation, the horizon on the formation tops labelled Lower Guru Formation, Basal sand, and Massive sand was identified, and faults were discovered. Normal faults with horst and graben structures were extremely obvious in the seismic interpretation, indicating that the area has undergone deformation and is in the extensional regime. The subsurface structures of the research region were identified using time, velocity, and depth contour maps. Based on the results of a petrophysical analysis of the Chak 66-01 well, the hydrocarbon bearing zone, average hydrocarbon, and water saturation, the hydrocarbon potential of the study region was determined; this was then cross-checked and the same conclusion was reached.
