India’s Hydrocarbon Outlook 2024 77 A Report on Exploration & Production Activities 7. PRANHITA-GODAVARI (PG) BASIN Pranhita-Godavari (PG) is a Category III basin, implying that the basin has entirely undiscovered inplace, that calls for intense exploration for a potential discovery. The geographical area of the basin partially overlaps with the state(s) of Andhra Pradesh, Chhattisgarh, Madhya Pradesh, Maharashtra and Telangana. Source: DGH Internal Source: DGH Internal The basin is a NW-SE trending intracratonic rift, located over Peninsular India and bounded by metamorphic rocks of Bastar to its northeast and Dharwar cratons to its southwest. Potential plays are envisaged in Talchir, Barakar, Lower, Middle and Upper Kamthi Formations. Geological data indicates presence of about 4 to 5 Km of sediments. The oldest sediments known from surface exposures are the Lower Proterozoic overlain by Gondwana sediments. The basin has the close analogy withMandapeta area of the KG Basin. Lower Gondwana Barakar and the Barren sediments are rich in organic carbon content with source rock characteristics, with TOC 1.98-30.4%. Development of reservoir facies is expected both in Barakar and Kamthi Formations. Structural entrapment is envisaged in the Sironcha block.
