Abstract: A method for producing minerals and, more specifically, for producing hydrocarbons, by hydraulic fracturing of the rock, can be used for the optimization of formation fracturing crack processing conditions. The method includes splitting a main stream of a propping agent suspension in a fluid at a mixer output into at least two flows having different volume delivery rates, and comingling the at least two flows before delivering to the hydraulic fracturing zone.

Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) and proppant-spacing filler material (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the material (24), and removing the filler material (24) to form open channels (26) around the pillars (28). The filler material can be dissolvable particles, initially acting as a consolidator during placement of the proppant in the fracture, and later dissolving to leave flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

Abstract: A method of proppant placement within a fracture may include injecting a proppant-laden fluid through the wellbore into the fracture under pressure to form at least one proppant pillar within the fracture, the proppant-laden fluid comprising a non-spherical proppant ossessing at least some roughness or at least some roughness and angularity; wherein upon removal of the pressure the diameter of the proppant pillar increases by less than about 100 percent of the initial diameter.
