  • Concept TransformationIn pursuit of conventional Oil/Gas Exploration over the years, Geologists regarded Shales as:Source Rock by virtue of the richness of organic material content, its thermal maturity, hydrocarbon generation potential and geographic spread over large areasCap Rock by virtue of their impermeable nature and compactness thus acting as good seal

  • As per working group of Petroleum & Natural Gas ,Govt.of India

    the Domestic Gas Production during the period 2016-17 to 2021- 22 will not increase significantly the demand for gas in the country will be met by import of LNG to the tune of 130 MMSCMD i.e. 40% of then demand in 2013-14 and will increase to 184 MMSCMD i.e. 45% of then demand expected in 2016-17. Thereafter, the country may import both LNG and cross-country piped gas to the tune of 258 MMSCMD or 57% of then demand in 2017-18 to2021-22.As per World Energy Outlook Report(2009)-India will be the only country in the world investing 6.0% of its GDP on Oil /Gas importsThis is a very serious situation as during the period 2025-2030 the import of Crude Oil may reach 90% and import of Natural Gas can be between 54-60%. Indian Economy can not sustain the projected Energy importsThis may have disastrous consequences for countrys Security and Foreign Exchange position.

  • Why are they Vary?

    Various Agencies have projected the Resources based on their perceptions of Indian Shales. Thus The resource prognostications are varied and are subjective.Lack of Shale gas specific laboratory investigations/dataCrucial parameters on Indian shales in terms of their heterogeneity, gas content, TOC, VRo, diagenesis, brittleness etc are not available Shale isopachs, dispositions and TOC ,VRo and Gas concentration maps are not prepared for many potential basinsNo pilot wells /parametric wells are drilled to explore shale gas in all our basins

  • Commendatory Factors
