SYSTEM AND METHOD OF PROCESSING UNDERGROUND SEAM Russian patent published in 2018 - IPC E21B43/267 C09K8/62 

FIELD: technological processes; mining.

SUBSTANCE: variants of a method for treating a subterranean formation are proposed. Method of one embodiment includes: introducing a dilute stream comprising a non-bridging amount of carrier fibers in low viscosity fluid carrier medium, high pressure line; adding a proppant to the diluted stream to form a proppant-filled flow; injection of a proppant-filled flow from the high-pressure line into the first rupture; introducing a high-fill flow containing a deflecting agent into a high-pressure line to combine with the diluted stream to form a deflecting slurry; feeding the deflecting slurry from the high pressure line to the first rupture gap for fluid in the second gap; and injecting the proppant-filled flow from the high-pressure line into the second rupture.

EFFECT: technical result is to increase the efficiency of processing the underground formation.
