Hydraulic fracturing is a wellstimulated technique that allows the flux of hydrocarbon to the surface to create fractures in rock formations. Fractures consist of pumping big quantities of fluid at elevated stress, including proppants such as ceramic pallets, sand, water and chemical additives that extend fractures in

Contact2018-5-28 Hydraulic geometry. Hydraulic geometry is of two types, at-a-station and downstream, and encompasses relations of channel width, depth, velocity, roughness, and slope each with discharge (Wolman 1955 ). Leopold and Maddock ( 1953) derived these hydraulic geometry relations which are of
Contact2015-6-30 Hydraulic fracturing is a stimulation technique used to increase oil and gas production from underground rock formations. Hydraulic fracturing involves the injection of fluids under pressures great enough to fracture the oil- and gas-producing formations. The fluid generally consists of water, chemicals, and proppant (commonly sand).
Contact2020-8-16 Hydraulic mining, use of a powerful jet of water to dislodge minerals present in unconsolidated material, including mine tailings, placer deposits, alluvium, laterites (soil rich in iron oxides), and saprolites (soil rich in clay). It has also been applied to consolidated materials from sandstones through coal to hard rock. Hydraulic mining encompasses
Contact2001-5-21 The study analyzed the data that was gathered for over 300 hydraulic fracturing jobs pumped using delayed-cross linking, CMHPG based gels, collected over a period of one year. The data encompasses gel concentrations ranging from 30 lbm/Mgal to 60 lbm/Mgal for tubular sizes ranging from 2–3/8 inch to 4–1/2 inch.

ContactHydraulic jumps occur as rapid transitions from supercritical to subcritical flow [Chanson, 1999], and are recognized to be controlled by variations in channel geometry and/or stream discharge [e.g., Mossa et al., 2003], but the extent of this control is largely unknown [Balachandar et al., 2000]. In experimental flume studies, it is possible to manipulate the hydraulic jump regime independently of discharge through the
