Source Rock Palynological Model for Exploration of Fossil Fuels in Krishna-Godavari Basin
Subscribe/Renew Journal
Exploration for hydrocarbon depends largely upon integration of surface and subsurface geological, geophysical and geochemical data. The vast majority of fossil hydrocarbons was formed by the alteration of sedimentary organic matter which originate from a variety of different source materials including aquatic and terrestrial biotas. Better understanding of the petroleum system (which includes source, migration and accumulation) in any basin is necessary for hydrocarbon exploration. Assessment of source rock is based upon parameters like organic matter types, richness of organic matter, maturation and paleoenvironrnent. The various geochemical and source rock palynological parameters are also considered synergistically to decipher source rock potential sequences in Cretaceous and Pre-Cretaceous sediments of Krishna-Godavari Basin.
Source rock palynological model is prepared for various formations viz., Pennar Shale, Krishna Formation, Golapalli Formation, Gajulapadu Shale, Raghavapuram Shale and Tirupati Sandstone to depict spatial and temporal distribution of source rock facies.
