Assessment of Shale Gas Potential in Disang Shale of Upper Assam Basin.
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
Neither any subsurface sample nor even any subsurface location is known for Disang Shale existence. However huge outcrop samples are known to exist which appear to grey or black colour with occasional good amount of TOC and high maturity but not always proved to be good source rock. Because these are surface samples the source rock characters of HI, PI are not expected to be proved because samples are possibly acted by oxidation or biodegradation due to which SI, S2, TOC and Tmax values are supposed to be changed. Therefore subsurface Disang shale is not proved whether to be a source rock or not. Also because its subsurface location is not known its maturity is also not expected. However because of its colour and TOC existence it is assumed to be possible source of the available hydrocarbons in the basin. Attempt is made here to evaluate possible shale gas potential if it is a source rock or not. It is known that shale gas in a shale is possible to exist if the shale is a source rock and ultimately failed primary migration or even if it is not a source rock but could store some migratory oil and achieved maturity of gas window to convert stored oil to gas and also failed primary migration. Primary migration of oil & shale porosity is assumed for Disang Shale equivalent to Barnett Shale of USA. The calculated amount shows the expected shale gas potential of 575.87 million tonnes of shale gas if it had thickness of 3 km around 2 kmx1km areal extent and it worked as a true source rock with parameters same as outcrop sample MCR-2 in Assam-Arakan Basin. If it was not a source rock but received migratory oil then the expected shale gas potential is 339.15 million tonnes around the same 3km by 2kmx1km shale extent
