Methods and compositions for consolidating particulate matter in a subterranean formation are provided. In one embodiment, a method of treating a subterranean formation includes coating a curable adhesive composition comprising a silane coupling agent and a polymer having a reactive silicon end group onto proppant material; suspending the coated proppant material in a carrier fluid to form a proppant slurry; introducing the proppant slurry into a subterranean formation; and allowing the curable adhesive composition to at least partially consolidate the proppant material in the subterranean formation.

Methods including the steps of providing an injection well having unconsolidated particulates in one or more formation intervals along the wellbore that accept injection fluid; providing a consolidating treatment fluid comprising a base fluid and a consolidating agent; introducing the consolidating treatment fluid through the injection well, while the well is under injection, such that the consolidating treatment fluid enters into a portion of a formation interval along the wellbore that accepts injection fluid; and, allowing the consolidating fluid to consolidate formation particulates therein. The methods may be performed such that the percentage of consolidating agent varies over the course of the treatment or the rate of injection varies over the course of the treatment.

Method of treating a subterranean formation comprising providing a consolidation fluid, introducing the resin consolidation fluid into a subterranean formation comprising unconsolidated particulates; and, curing the resin to at least partially consolidate the unconsolidated particulates. The consolidation fluid comprises a resin in emulsified form with an aqueous external phase and an organic internal phase wherein the emulsified resin does not comprise a hardening agent and an aqueous base fluid that further comprises a hardening agent. The consolidation fluid may further comprise an emulsifying agent.
摘要:
Treatments and compounds useful in subterranean formations are discussed, with particular attention to those where particulates may be subject to water intrusion. Certain methods pertain to providing diffusion barriers for particulates. Of these, certain diffusion barriers may provide hydrophobic coatings to the particulates, certain diffusion barriers may provide fillers that may act to prevent water intrusion into surface features of particulates, and certain diffusion barriers may be initiated with diagenesis source material.

Methods of drilling wellbores, placing proppant packs in subterranean formations, and placing gravel packs in wellbores may involve fluids, optionally foamed fluids, comprising nanoparticle suspension aids. Methods may be advantageously employed in deviated wellbores. Some methods may involve introducing a treatment fluid into an injection wellbore penetrating a subterranean formation, the treatment fluid comprising a base fluid, a foaming agent, a gas, and a nanoparticle suspension aid; and producing hydrocarbons from the subterranean formation via a production wellbore proximal to the injection wellbore.
摘要:
Methods for enhancing the conductivity of propped fractures in subterranean formations may involve using a tackifier to minimize particulate settling during particulate placement operations in subterranean formations. For example, methods may involve introducing a first treatment fluid into a wellbore extending into a subterranean formation at a pressure sufficient to create or extend at least one fracture in the subterranean formation; and introducing a second treatment fluid into the wellbore at a pressure sufficient to maintain or extend the fracture in the subterranean formation. The first treatment fluid may include at least a first aqueous base fluid and a tackifier. The second treatment fluid may include at least a second aqueous base fluid and a proppant particle.
摘要:
Consolidation fluids comprising: an aqueous base fluid comprising a hardening agent; an emulsified resin having an aqueous external phase and an organic internal phase; a silane coupling agent; and a surfactant. The consolidation fluid itself may be emulsified and further comprise an emulsifying agent. The consolidation fluid may also be foamed in some cases.
