the process of:

a) Quarrying

b)Shaft mining

c) Open cast mining

d) None of these​

Answer 1

Answer:

Conventional natural gas and oil deposits are found in permeable rocks, trapped below impermeable rock. These deposits can be extracted by drilling down through the impermeable rock into the permeable rock. But gas and oil are also trapped in the spaces within impermeable shale rock

Extracting gas from “tight” rock formations usually requires expensive and difficult methods, such as fracking and acidizing. Acidizing is similar to fracking. An acid (usually hydrochloric acid) is injected into the natural gas well. The acid dissolves the tight rock that is blocking the flow of gas.
