Recently, an extraordinary interest has arisen in the world in the use of natural gas obtained from oil shale as a fuel. Shales were formed 450 million years ago at the bottom of the sea from plant and animal remains.
A drilling rig is used to make a vertical well to the depth of the shale formation.
Hydraulic fracturing of the formation is carried out using a water hammer with a water-containing jet, which uses various chemicals to help open the pores. This includes organic acid salts, refinery waste and even diesel!
During the implementation of a water hammer, a large amount of fresh water is used, which can be considered lost free of charge!
Gas is squeezed to the surface of the earth, and voids inside the earth's strata remain filled with hazardous chemicals that cause irreversible environmental reactions.
If the pressure of the liquid inside drops, then ground falls, earthquakes in nearby areas begin. There are also chemical liquid spills on the surface of the adjacent territories.
Greenpeace is an international independent non-governmental environmental organization founded in 1971 in Canada and strongly opposes the extraction of shale gas and shale oil.
