对印度近海的地质和地球物理数据的研究揭示了两个地质上不同的地区，推断存在天然气水合物：印度半岛的被动大陆边缘和沿着安达曼会聚边缘。印度国家天然气水合物计划（NGHP）01考察旨在研究印度半岛和沿着安达曼会聚边缘的天然气水合物的出现，特别强调了解地质和地球化学控制天然气水合物的出现在这两个不同的设置。NGHP远征01在Krishna-Godavari、Mahanadi和Andaman盆地确定了天然气水合物的存在。该探险队发现了迄今为止有记录的最丰富的天然气水合物积聚之一（Krishna-Godavari盆地的10号地点），记录了迄今为止已知的最厚和最深的天然气水合物稳定区（安达曼海的17号地点），并确定了Mahanadi盆地（19号地点）存在一个完全发育的天然气水合物系统。
Studies of geologic and geophysical data from the offshore of India have revealed two geologically distinct areas with inferred gas hydrate occurrences: the passive continental margins of the Indian Peninsula and along the Andaman convergent margin. The Indian National Gas Hydrate Program (NGHP) Expedition 01 was designed to study the occurrence of gas hydrate off the Indian Peninsula and along the Andaman convergent margin with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings. NGHP Expedition 01 established the presence of gas hydrates in Krishna- Godavari, Mahanadi and Andaman basins. The expedition discovered one of the richest gas hydrate accumulations yet documented (Site 10 in the Krishna-Godavari Basin), documented the thickest and deepest gas hydrate stability zone yet known (Site 17 in Andaman Sea), and established the existence of a fully-developed gas hydrate system in the Mahanadi Basin (Site 19).
