2-D Seismic Interpretation Of Kadanwari Area, Khairpur District, Sindh, Pakistan

Abstract

This dissertation involves the study of 2D seismic interpretation of the area lies in the Kadanwari Gas discovery which is located in the Lower Indus Basin, Pakistan. The key objective includes the delineation of subsurface structure suitable for Hydrocarbon accumulation. This part of the basin has a well-known exploration history from 1989 to 1992. The well and the seismic data reveal the presence of Mesozoic-Cenozoic sedimentary cover which has been involved through extensional and then transtensional episodes of Indo-Pakistani plate related to Cretaceous rifting and drifting, the present work reveals the presence of structure style which shows the geometry of negative flower structures. The seismic lines for this dissertation were provided by LMK Resources by permission from the Directorate General of Petroleum Concession (DGPC). A total of 11 seismic lines were for seismic interpretation in which 6 horizons were picked by well correlation. The fault trend is marked according to the regional geology and the effect of regional geology on the study area was analyzed. Three Reflectors (Yellow, Green, and Purple) represented by Pirkoh, Lower Goru E sand, and Albian Aptian Formation are marked by a check shot survey of the available Kadanwari well -1 and its reflection prominence. Two-way travel time from the seismic section was used to create time contour maps of Pirkoh, Lower Goru E sandstone, and Albian-Aptian. Finally, constructions of contour maps provided the structural highs suitable for accumulation of hydrocarbon were identified
