Abstract EN
Southern Indus Basin is one of the promising regions in Pakistan as a commercially producing oil and gas perspective.
The current research presents the geochemical characterization of the Ranikot Formation shales from Southern Indus Basin based on total organic carbon (TOC), Rock-Eval (RE) pyrolysis, organic petrography, gas chromatography-mass spectrometry (GC-MS), and x-ray diffraction (XRD) analyses.
The average TOC of Ranikot shale is 4.6 wt.
%, indicating very good hydrocarbon potential.
Types III/IV kerogens were identified in the Ranikot shale.
The maceral data also suggest that the Type of kerogen present in the Ranikot shale is dominantly Types II-III, with the minor occurrence of Type IV.
The vitrinite reflectance, pyrolysis Tmax and methylphenanthrene indices values specify immature levels of the shales.
The normal alkane data reflect that marine macrophyte, algae, and land plants were contributed to the organic matter of Ranikot shales.
Dibenzothiophene/phenanthrene ratio (0.11), phytane/n-C18 ratio (0.53), pyrite, and glauconite elucidate that the depositional environment of the Ranikot shale is marine.
The XRD analysis of the shale from the Ranikot Formation revealed that it is brittle shale and dominated by 39.5 to 50.9 wt.
% quartz.
The present study, integration with the US EIA report demarcated the Ranikot Formation influential horizon as a shale gas resource
