Oil Shale reserves in India are Greater than 15 Billion Tons.[iii] North-East India is endowed with rich deposits of coal. The coal is found in the Barail Formation of Tertiary age. Carbonaceous shale occurs interbedded with the coal. The presence of coal and shale has been recorded in wells drilled Past estimates of India’s shale reserves vary widely from ONGC’s 187 trillion cubic feet (TCF) of shale gas in 5 basins to US Energy Information Administration ’s 584 TCF of shale gas and 87 billion barrels of shale oil in 4 basins, and oilfield services provider Schlumberger ’s 300 to 2100 TCF gas. The US has an estimated 1.8 trillion barrels of oil trapped in shale, most of it concentrated in the Green River Formation, which covers northwest Colorado and parts of Utah and Wyoming. This estimate is more than all the proven reserves of crude oil in the world today. Earlier, in a prospectivity analysis of shale oil carried out of the Directorate General of Hydrocarbons of India in the North East states of Arunachal Pradesh and Assam, shale oil reserves are estimated to the tune of 137 billion tones with a recovery factor of 10-20 per cent. Shale gas & oil is defined as natural gas & oil from shale formations. The shale acts as both the source and the reservoir for these unconventional hydrocarbons. Older shale wells were vertical while more recent wells are primarily horizontal and need artificial stimulation, like hydraulic fracturing, to produce. Fracking technology sends high pressure streams of water, sand and chemicals into shale formations to bring up the oil and gas. A former Oil India chairman C. Ratnam has for long advocated that India exploit its shale reserves in Arunachal, which some experts estimate to be up to 14 billion tonnes. In India, shale oil and gas reserves are found mainly in Tamil Nadu, Andhra Pradesh and Rajasthan. “These are positive developments for the natural gas sector.
9 Mar 2020 However, with the discovery of shale in the U.S. and advances in drilling It holds three-quarters of the world's conventional oil reserves and has such as China and India, putting additional influence on prices in the face of but the largest and highest quality oil shale deposits are in sparsely populated areas in rapidly developing countries such as China and India. These emerging Anshu Mittal, of Deloitte Support Services India Pvt. Ltd., is an oil and gas research additions + production – net liquids and gas reserves acquired)/ production. 16 Jan 2020 The company expects to start initial shale gas exploration work of drilling Despite having one of the largest coal reserves in the world, India's
Exploration for assessing the Shale gas/oil prospectivity has been initiated in 4 and A&AA Basins as per the policy guidelines notified by Government of India million tonnes (oil and oil equivalent gas) of initial in-place on-land reserves. According to estimates by EIA, India has 96 tcf of recoverable shale gas reserves. However there has been a recent downward revision in the estimates. India's 13 Nov 2019 ➢ONGC and OIL given the right to drill for shale oil and gas in the blocks they have, but fresh auction proposed for all other deposits. India's first 9 Mar 2020 However, with the discovery of shale in the U.S. and advances in drilling It holds three-quarters of the world's conventional oil reserves and has such as China and India, putting additional influence on prices in the face of
Today, the ONGC is the largest producer of the oil and gas in the country, contributing to about 72.4% of the crude oil and 48.5% of the natural gas production. At present, over 78% of India’s oil requirements are being met by imports. Shale Gas in India. Shale refers to a sedimentary rock resulted from compaction process of small old rocks containing mud and minerals – such as quartz and calcite, trapped beneath the earth surface. The shale gas is the natural gas trapped within these shale rocks.

To strengthen its hydrocarbon resource base, India has identified six basins as areas for shale gas exploration: Cambay (Gujarat), Assam-Arakan (North East), Gondwana (Central India), Krishna Godavari onshore (East Coast), Cauvery onshore, and Indo-Gangetic basins. The first phase of the expansion, to have a capacity of 18.33 million barrels (2.5 million tons) was commissioned last week, the executive also said. India already has two strategic petroleum reserve facilities with a modest capacity: 20.52 million barrels, or 2.8 million tons.
