A correlative maturity study integrated with seismic attributes for determining the shale gas potential of Ghazij Formation is carried out. Analysis of post-stack seismic attributes has been frequently used to identify areas of high exploration potential within shale resource plays. Seismic and well data have been utilized for the analysis of maturity trends in the shale facies of Ghazij Formation. Total organic carbon content (TOC), burial history, Vitrinite Reflectance (Ro), thermal history and porosity values have been computed at Pirkoh-01 well, which are laterally compared with the maturity results in Bambor and Sui areas. In addition, analysis is carried out to detect the bright spots using the seismic attributes, which depicts positive results for the presence of the sweet spots around 1100–1350 ms in the southern synclinal part of the study area. | Turkish Journal of Earth Sciences Turkish J Earth Sci 2022 31 1-19 http earth TÜBİTAK Research Article doi yer-2105-36 Exploring the untapped gas potential of Ghazij shale in Pirkoh area Pakistan Integrated approach of attribute analysis and maturity modeling 1 2 3 1 4 Muhammad Raiees AMJAD Sarfraz KHAN Umair Bin NISAR Urooj SHAKIR Khawar Ashfaq AHMED 1 Department of Earth and Environmental Sciences Bahria University Islamabad Pakistan 2 NCE in Geology University of Peshawar KP Pakistan 3 Centre for Climate Research and Development CCRD COMSATS University Islamabad Islamabad Pakistan 4 Department of Meteorology COMSATS University Islamabad Islamabad Pakistan Received Accepted Published Online Final Version Abstract A correlative maturity study integrated with seismic attributes for determining the shale gas potential of Ghazij Formation is carried out. Analysis of post-stack seismic attributes has been frequently used to identify areas of high exploration potential within shale resource plays. Seismic and well data have been utilized for the analysis of maturity trends in the shale facies of Ghazij Formation. Total organic carbon content TOC burial history Vitrinite Reflectance Ro thermal history and porosity values have been computed at Pirkoh-01 well which are laterally compared with the maturity results in Bambor and Sui areas. In addition analysis is carried out to detect the bright spots using the seismic attributes which depicts positive results for the presence of the sweet spots around 1100 1350 ms in the southern synclinal part of the study area. The computed results showed that Ghazij shales lie within the oil and gas generation window having temperature values ranging between 90 150 C with Ro. This correlative maturity study declares Ghazij Formation as a potential shale gas reservoir. After analyzing all these facts it can be concluded that the shales of the Ghazij Formation do .
