A hydraulic fracture is formed by pumping the fracturing fluid into the wellbore at a rate sufficient to increase the pressure downhole to a value in excess of the fracture gradient of the formation rock. The pressure causes the formation to crack, allowing the fracturing fluid to enter and extend the crack farther into the formation. To keep this fracture open after the injection stops, a solid proppant, commonly a sieved round sand, is added to the fracture fluid. The propped hydraulic fracture then becomes a high permeability conduit through which the formation fluids can flow to the well.  2, record 1, English, - hydraulic%20fracture

... horizontal drilling is usually undertaken to achieve important technical objectives related to specific characteristics of a target reservoir [such as] the reservoir rock's permeability, which is its capacity to conduct fluid flow through the interconnections of its pore spaces(termed its "matrix permeability"), or through fractures(its "fracture permeability"), and/or the expected propensity of the reservoir to develop water or gas influxes deleterious to production, either from other parts of the reservoir or from adjacent rocks, as production takes place(an event called "coning").  2, record 2, English, - fracture%20permeability

... another possible way of creating permeability in hot dry rocks is «impact fracturing». This method... [may be described in its principle. ] A bore, cased except near the lower extremity, is surmounted by a hydraulic accumulator, filled with water and pressurized by means of a pump until the accumulator weight is lifted. The lifting pressure should be perhaps about 90% of the estimated hydro-fracturing pressure. A dynamic blow would then be struck upon the top of the water column by means of some device resembling a pile-driver, so that shock waves would travel to the base of the bore and be reflected up and down at attenuating intensity. Very high instantaneous pressures would be generated which would fracture the rock, and it is expected that the steepness of the pressure rise would be such as to resemble explosive action, so that the «star» formation... would be produced.  1, record 5, English, - impact%20fracturing
