Shale Gas Potential in Telisa Formation, Central Sumatera Basin as a Review to Fulfill Future Energy Demand

Abstract

These days, world’s energy demand is increasing because of so many factors and at the same time conventional energy resource was decreasing for a last few years. In this situation, shale gas rise and rapidly growth to fulfill world’s energy demand. Shale gas is a natural gas which is trapped within the shale formation because of shale impermeable characteristic. Shale refers to fine grained, laminated, clastic sedimentary rocks that can be rich of organic matters. Focus study in this research is located in Telisa rock formation, Central Sumatera. This research methods used literature study concerning in regional geology including regional stratigraphy, structural geology and geochemistry analysis. Telisa formation has a great potential of shale gas resource. Therefore, it is interesting to discuss about Telisa formation potential of shale gas to alternate conventional energy to fulfill future energy demand.
