Hydraulic fracturing jobs are carried out at well sites using heavy equipment including truck-mounted pumps, blenders, fluid tanks, and proppant tanks. A hydraulic fracturing job is divided into two stages: the pad stage and the slurry stage. In the pad stage, fracturing fluid is injected into the well to break down the formation and create a pad.

16/2/2017, · The, concept of (hydraulic) fracturing with pressure, instead of explosives grew in the 1930s. Beginning in 1953, water-based fluids were developed using different types of gelling agents. Nowadays, aqueous fluids such as acid, water, brines, and water-based foams are used in most fracturing treatments.

Meanwhile, the effect of gravity ,separation, in a primary fracture on the ,fracturing, fluid is significant [20]. Until now, there have been few studies on the mechanism of FFR. The mechanism and rule of retention in rough fractures are unclear, and the relationship between the ,flowback, rate and development of artificial fractures is uncertain.
