Abstract

Mesozoic exploration is being carried out in Indian Sedimentary basins for exploration of oil & gas reservoirs. It has gained lot of importance worldwide in terms of huge reserves of oil& gas. Much of Tertiary resources are being exhausted and to meet demands of oil & gas requirements of India, much focus is required for exploration of Mesozoic sediments. The KG, Cauvery, Kutch, Kerala-Konkan, Cambay and Rajasthan basins are having good potential of hydrocarbons in Mesozoic section. The challenges are mainly (1) deeper target depths offshore (2) mask of continental flood basalts of Deccan Traps and older traps even particularly in Kutch, KK and Cambay basin (3) Imaging sub-basalt Mesozoic sequence as most of reflected energy dissipates on onset of traps (4) techno-economics. The basin wise stratigraphy, petroleum systems and perspective for Mesozoic exploration is discussed and challenges in exploration. The future of Indian exploration lies on accelerated efforts to tap huge potential of H/C reserves in Mesozoic sequences.
