A polymerizable chemical system for consolidating particulates in a subterranean formation including a liquid resin, a curing agent, and a permeability enhancing additive. The chemical system is a homogenous composition that polymerizes to forms a solid upon heating at a temperature greater than 60° C. Consolidating particulates in a subterranean formation includes providing a polymerizable chemical system comprising a liquid resin, a curing agent, and a permeability enhancing additive to a subterranean formation, and polymerizing the polymerizable chemical system to consolidate particulates in the formation to yield a porous consolidated particulates pack.

A solids-control fluid for controlling flow of solids in a subterranean formation is disclosed herein. The solids-control fluid can include a diluent and a curable resin. The diluent can include a mutual solvent and an ethylene glycol. The curable resin can be dispersed within the diluent for controlling flow of solids in the subterranean formation.

A method of treating a subterranean formation including providing a treatment fluid comprising a hardenable acid curable resin and a hydrolysable strong acid ester. The treatment fluid is combined with a diluent fluid and is introduced into a subterranean formation. Upon the hydrolyzing of the ester in the formation and the contacting of unconsolidated proppants, the treatment method produces consolidated proppants.

A method may include: introducing a treatment fluid into a subterranean formation, the treatment fluid comprising: an aqueous brine; and a hydrolysable resin precursor; allowing the hydrolysable resin precursor to hydrolyze in the subterranean formation to form at least a polymerizable resin precursor monomer; and allowing the polymerizable resin precursor monomer to polymerize to form a polymerized resin in the subterranean formation.

One or more embodiments relates to a productive consolidated sand pack product. The sand pack product may be a cured resin that is bound to sand particles and has a porous structure. The sand pack product is obtained from curing a resin composition which may include a resin, a curing agent, a chemical blowing agent, a surfactant, a carrier fluid, a pH agent, and a salt. The porous volume may include one or more of trapped gas, bubbles, and open or connected pore space.

A method of treating a subterranean formation including introducing a preflush solution comprising a first aqueous base fluid and a surfactant onto the face of a fracture in a subterranean formation with particulates in the fracture; introducing a stabilizing composition onto the fracture face of the formation and onto the particulates proximate the fracture face, the composition including a second aqueous-based fluid; a silane-based resin; and a silane-based curing agent; allowing the stabilizing composition to consolidate the particulates proximate the fracture face, thereby stabilizing the fracture face and proximate particulates in the fracture. A method includes introducing a conformance treatment fluid into at least a portion of a subterranean formation, said treatment fluid including: an aqueous-based fluid; a silane-based resin; and a silane-based curing agent; and allowing the conformance treatment fluid to at least partially seal the pores of the formation.

A method of making a proppant-gel matrix comprising: a) hydrating a gelling agent to form a hydrated gelling agent; b) adding a basic compound to the hydrated gelling agent to form a basic hydrated gelling agent having a pH in the range of 11.5 to 14.0; c) mixing the basic hydrated gelling agent and a proppant to form a basic hydrated gelling system; and d) adding a crosslinking agent to the basic hydrated gelling system to form the proppant-gel matrix, is disclosed. The proppant-gel matrix can then be used as a fracturing fluid in a hydraulic fracturing process.
