Bottom simulating reflector (BSR) is the main marker for the identification of gas hydrate in the subsurface sediments from seismic data. Based on BSRs mapped on the seismic sections, two national drilling, coring and logging programs were conducted in 2006 and 2015, respectively, which discovered a huge amount of gas hydrate along the Indian continental margin. The first Indian National Gas Hydrate Program Expedition 1 (NGHP-01) found gas hydrate as fracture-filled and pore-filled in fine-grained shallow sediments of Krishna-Godavari, Mahanadi and Andaman offshore basins. NGHP-02 was conducted in the deeper water parts of Krishna-Godavari and Mahanadi offshore basins to find gas hydrate deposits in the coarse-grained sediments. Well log and core data collected during the second expedition in 25 sites reveal a huge amount of gas hydrates distributed as pore-fill, fracture-fill and both pore- and fracture-fill (mixed) morphologies in sand and silt rich sediments. Rock physics modelling of sonic velocity and resistivity log shows that about 80-90% of the pore spaces are filled with gas hydrates at some depths, which are closely matching with available pressure core measurements. Lateral distributions of gas hydrate are delineated by integrating the well logs and seismic data. However, for the proper delineation and quantification of gas hydrate, characterisation of the reservoir is very important in terms of lithology, porosity, permeability, anisotropy and the morphology of gas hydrate distribution. Full waveform inversion of seismic data, advanced rock physics modelling and neural network technique, etc. are very useful for assessing the gas hydrate reservoirs. Based on certain assumptions, the estimated reserves in Indian offshore is about 1900 trillion cubic meters and 1% production can serve India’s energy requirement for a few decades. However, the estimated reserves should be further refined incorporating more drilling and coring data.
