To dispose of this wastewater, the liquid is re-injected into geologic formations deep underground.

Other issues included developing new instruments and techniques to monitor rock formations deep underground, said Aradóttir.

That water is saltier than seawater and may contain naturally occurring arsenic and radioactive elements trapped inside rock formations deep underground.

Oil and gas companies developing fields in Pennsylvania, Ohio, Texas, Louisiana, Arkansas and North Dakota rely on a process called hydraulic fracturing, which produces natural gas by blasting water and chemicals into energy - rich rock formations deep underground.

New techniques promised to unlock huge reserves of natural gas in the Marcellus Shale, a geologic formation deep underground beneath Pennsylvania, New York, West Virginia and Ohio said to contain enough natural gas to supply the East Coast for up to 50 years.

Not exact matches

Others described mitigation potential through carbon capture and storage where carbon dioxide is captured during energy production and then transported to a location where it can be injected deep underground into various geologic formations and through reforestation.

Fracking, as the technique is known, is the use of chemical - laced water injected deep underground to create fissures in underground rock formations and release natural gas and oil.

Hydrofracking relies on a high - pressure blend of chemicals, sand and water pumped deep underground to break up gas - bearing rock formations, freeing gas to rise up the well to the surface.

To free the gas trapped in the Marcellus and other shale formations, drillers pump millions of gallons of water mixed with sand and chemicals deep underground under pressure.

Carbon capture and storage, or CCS, is a family of technologies and techniques that enable the capture of carbon dioxide (CO2) from fuel combustion or industrial processes, the transport of CO2 via ships or pipelines, and its storage underground, in depleted oil and gas fields and deep saline formations.

In theory, CCS takes carbon dioxide emitted from the source, typically coal - fired power plants, compresses the gas and injects it deep underground in subsurface geological formations for «indefinite isolation from the atmosphere,» according to the World Resources Institute.

BECCS is another system that uses fast growing trees to be burned for electricity generation, and emissions stored underground in old oil wells, and deep permeable rock formations, but this needs gigantic areas of land, irrigation and fertiliser and expensive, energy intensive processes.
