Feb 11, 2022 · Hydraulic fracturing – commonly known as fracking – is the process used to extract shale gas. Deep holes are drilled down into the shale rock, followed by horizontal drilling to access …

Shale gas has been produced for years from shales with natural fractures; the shale gas boom in recent years has been due to modern technology in hydraulic fracturing (fracking) to create extensive …

Nov 29, 2025 · Fracking Three steps in the extraction of shale gas: drilling a borehole into the shale formation and lining it with pipe casing; fracking, or fracturing, the shale by injecting fluid under …

This typically involves injecting pressurized fluids to stimulate or fracture shale formations and release the natural gas. Sand pumped in with the fluids (often water) helps to keep the fractures open.

Sep 10, 2025 · Hydraulic fracturing, or fracking, is a method used to extract natural gas and oil from deep rock formations known as shale. Using this method, drilling operators force water, sand, and a …

Shale gas or unconventional gas is extracted from the impermeable shale through a process called hydraulic fracturing (also known as hydrofracking or fracking). A crude form of this technique, …

Jul 7, 2020 · Fracking is a type of drilling technique that involves fracturing rock deep underground in order to extract shale gas – a natural fuel that is trapped within shale formations.

Shale Gas and Fracking: The Science Behind the Controversy explains the relevant geological principles before examining the peer-reviewed evidence and...

Feb 5, 2013 · Hydraulic fracturing or fracking creates fractures in the shale formation to release the gas. A fracturing fluid is pumped under high pressure (ca. 100 bar) into the drilling pipe to widen fractures …

Jan 14, 2026 · RESTON, Va. — The U.S. Geological Survey released its assessment of undiscovered gas and oil in the Woodford and Barnett shales in the Permian Basin, assessing that there are …
