hydrofracturing, vbl. n.|ˌhaɪdrəʊˈfræktjʊərɪŋ|
[f. hydro- + fracturing vbl. n.]
The process of fracturing subterranean rock by the injection of water into existing fissures at high pressure, usu. in order to facilitate the passage of some fluid (esp. oil or water) through an otherwise impermeable barrier.
[1948: see hydraulic fracturing s.v. *hydraulic a. 1 b.] 1972N.Y. Times 5 Nov. iv. 8/6 Hydrofracturing is an oil-field technique in which water is pumped under high pressure down an oil well that has gone dry. 1976Nature 29 July 346/2 Interest centres on two techniques—the extraction of hot water from aquifers in sedimentary basins or near springs, and the hydrofracturing of rocks, usually granite, with a higher than average temperature. 1989New Scientist 4 Feb. 60/1 This type of cracking is commonly done to release oil from sedimentary rock, and is called hydraulic fracturing, or hydrofracturing.
Hence (as a back-formation) ˈhydrofracture v. trans., to fracture (rock) by this process; to subject (a fissure) to hydrofracturing.
1983Nature 13 Jan. 103/1 Two 2,000-metre boreholes for tapping geothermal heat in ‘hot dry rock’.., by pumping water down one and out of the other, were ‘hydrofractured’ just before Christmas to connect the two wells. 1987Science 27 Nov. 1227/2 When industry drillers hydrofracture a hole, they assume a few new fractures will form whose orientations are determined by the region's crustal stress. |
