Abstract:
The main purpose of the study is to evaluate hydrocarbon potential of the study area, in a part of Upper Indus Basin for delineation of potential leads for prospects. This has to be done by the analysis of 2D seismic data, which have been provided by Landmark, Pakistan with the permission of Directorate General of Petroleum Concessions, Islamabad, Pakistan. This data set comprises with 5 seismic lines. This dissertation presents the 2D seismic interpretation of Khushalgarh area in Upper Indus Basin. The Area is related to the North Postwar Deformed Zone (NP DZ) as a part of active fold and thrust belt formed by the Indo-Eurasian plate collision. The aim of this study is to re-evaluate the area to estimate the potential for discovery of hydrocarbons. Data used for seismic interpretation consists of five seismic lines 86-K h-16, 86-K h-17, 86-K h-18,86-K h-19 and 86-K h-96. The tops of two reflectors have been marked on seismic section, namely Kohat and Kuldana Formations. As the study area lies in the compressional tectonic regime hence the interpreted faults were marked as thrust faults. So, Seismic analysis in this area shows the presence of pop-up anticline, which can act as a trap for hydrocarbon in this area, as it is underlain by a source and overlain by a seal as well as shown by borehole stratigraphy of Jaywalk-01 well. The well was also drilled over this structure proving this pop-up structure a good structural trap.
