1. It is a natural gas-mainly methane.
2. Jambusar located near vadodara in Gujarat is India’s first shale gas exploratory successfully drilled in company region.
3. Shale gas formations are the reservoirs of low permeability.
4. Hydraulic fracturing is a technology used for the shale gas production.
Select the correct answer using the codes given:
(d) 1, 2, 3, 4
Shale gas refers to natural gas, especially methane that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas.
Horizontal Drilling and Hydraulic Fracturing
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. The production of natural gas from shale formations has rejuvenated the natural gas industry in the United States.
