On Tuesday, a joint expedition team which includes the Indian Government, Japanese scientists and United States Geological Survey (USGS), spotted producible Natural gas hydrates deposits in the Krishna-Godavari Basin in the Bay of Bengal. The vast treasure of the reserve would fulfil the energy needs of India, the country which mainly imports coal and petroleum fuels on large-scale.
Unlike the first expedition, the natural gas hydrate reserve found by the Indian National Gas Hydrate Program Expedition 02 under USGS and Indian government are producible. The US government agency said that the natural gas has to occur in sand reservoirs to make it “producible with existing technologies.”
“Advances like the Bay of Bengal discovery will help unlock the global energy resource potential of gas hydrates as well help define the technology needed to safely produce them,” stated Walter Guidroz, Energy Resources Program Coordinator at USGS.
Reports say that the natural gas hydrates deposits discovered now are located within coarse-grained sand-rich depositional systems in Krishna-Godavari (KG) basin. And it is made up of a sand-rich, gas-hydrate-bearing fan and channel-levee gas hydrate prospects. USGS said that the further research would involve production testing whether to know whether the natural gas production is “practical and economic.”
“The results from this expedition mark a critical step forward to understanding the energy resource potential of gas hydrates,” Tim Collett, USGS Senior Scientist, who was engaged in the expedition said.
“The discovery of what we believe to be several of the largest and most concentrated gas hydrate accumulations yet found in the world will yield the geologic and engineering data needed to better understand the geologic controls on the occurrence of gas hydrate in nature and to assess the technologies needed to safely produce gas hydrates.”
Natural gas hydrates deposits is a result of the ultimate comprehensive gas hydrate field venture made by the scientists from India, Japan and the United States. The discovery was a result of an exploration of the location from March to July 2015. On behalf of Ministry of Petroleum and Natural Gas, in association with the USGS Japanese Drilling Company and Japan Agency for Marine-Earth Science and Technology, the Expedition 02 team was headed by Oil and Natural Gas Corporation (ONGC).
