What is shale gas and fracking? Problems associated with shale gas extraction.

by

Shales are fine-grained sedimentary rocks formed of organic-rich mud at the bottom of ancient seas.Subsequent sedimentation and the resultant heat and pressure transformed the mud into shale and also produced natural gas from the organic matter contained in it. Over long spans of geologic time, some of the gas migrated to adjacent sandstones and was trapped in … Read more What is shale gas and fracking? Problems associated with shale gas extraction.

DMPQ-What is shale gas? Explain its composition and outline potential reserves in India?

by

Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce.  Typical components of oil shale gas are usually methane, … Read more DMPQ-What is shale gas?
