Assessing play potential and exploration risk is crucial for decision-making in the petroleum industry, impacting both exploration and production phases. India’s sedimentary basins, with their diverse depositional and tectonic histories, vary in exploration and development stages. These stages reflect differing levels of understanding of petroleum system elements, which are key to evaluating hydrocarbon potential and guiding exploration efforts. Exploration risk assessment helps identify critical factors such as source rock quality, reservoir presence, seal integrity, and migration pathways, allowing for efficient resource allocation and prioritizing areas for exploration. This study focuses on risk evaluation and play potential assessment in Indian basins, classified into nascent, consolidation, and mature stages based on exploration progress and understanding of petroleum systems. In nascent basins, where exploratory success has not yet been achieved, and data availability is low, focused basin studies using available data such as gravity, magnetic surveys, seismic data, and field exposures are essential. Basin evolution and depositional patterns can be analyzed using analogs from nearby basins, which help to prioritize exploration efforts. Risk analysis involves the extrapolation of point data to map the petroleum system elements. In basins with proven petroleum systems but no economic hydrocarbon production, play risk assessment is crucial. Play families based on tectonic evolution and depositional processes help identify potential hydrocarbon traps, and each petroleum system element for specific plays is assessed for its effectiveness in hydrocarbon generation and trapping. The study of fault systems and entrapment patterns helps distinguish productive hydrocarbon corridors. Additionally, the economic feasibility and prospectivity of unconventional plays should be assessed alongside conventional plays. For mature basins with proven systems and commercial production, prospect risk assessment is the key. This involves advanced studies of seismic and well data, as well as the further division of prospects into finer segments to better understand reservoir heterogeneities. In these mature basins, play risk analysis is also used to identify underexplored or unconventional reserves, optimizing exploration efforts and expanding the resource base.
