摘要: A method of stimulating the inflow of oil and/or gas from the wellbore, in particular, a hydraulic fracturing method, is disclosed. The method of hydraulic fracturing comprises the stages: injecting a slug of a proppant-free fluid through the well into a formation for hydraulic fracture creation and propagation; injecting a slug of proppant-laden slurry into the formation to create a proppant pack in the hydraulic fracture; injecting a slug of slurry that contains a fluid and the polyelectrolyte complex-based proppant aggregates to create permeable channels in the near-wellbore area of the hydraulic fracture; injecting a slug of a displacement fluid into the well. This sequence of operations allows avoiding the proppant slurry overdisplacement deep into the hydraulic fracture, maintaining high fracture conductivity, and increasing the well productivity.

摘要: A method to improve fluid flow in a hydraulic fracture from a subterranean formation which includes the steps of (1) formulating a slurry which comprises (a) proppant particles, (b) a carrier fluid, and (c) low density particles, wherein the fluid is capable of undergoing a transformation to cause an agglomeration of two or more proppant particles and/or low density particles; and (2) injecting the slurry into the formation; and (3) the agglomeration of the proppant particles and/or low density particles, is provided.
