Huge Scope for Upward Revision of India Shale Estimates

There is huge scope of upward revision of the shale gas estimates for India.

"There is huge scope of upward revision of the EIA estimates of 63 TCF for the country, which are merely based on the available conventional data from these basins," Oil and Natural Gas Corporation (ONGC) chairman Sudhir Vasudeva said earlier this week, Indo-Asian News Service (IANS) reported.

US Energy Information Administration (EIA) estimated that India's four basins - Damodar, KG, Cambay and Cauvery could have shale gas resources of around 290 trillion cubic feet, of which 63 TCF is considered technically recoverable.

The chairman said apart from the four basins, other basins which had large shale thickness and might be of interest for shale gas explorations in the country were the Assam, Bengal Gondwana, Vindhyan and Rajasthan basins, IANS reported.
