Hydraulic Fracturing of Oil & Gas Wells Drilled in Shale

Successful Use of Hydraulic Fracturing in Shale. In the early 1990s, Mitchell Energy began using hydraulic fracturing to stimulate the production of natural gas from wells drilled into the Barnett Shale of Texas. The Barnett Shale contained enormous amounts of natural gas; however, the Barnett rarely produced natural gas in commercial quantities.

Hydraulic mining - Wikipedia

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground ...
