摘要:
A low adhesion backsize (LAB) material made by mixing together materials, which self-associate. The mixtures can be waterbased and have high solids levels. The release is provided by functional groups such as silicones, fluorocarbons or long chain hydrocarbons. Release level can be tailored with release levels as low as the 0.5 gram/cm range to microsphere adhesives.

摘要:
Fluid compositions and methods of making and using same are described, the fluid compositions comprising at least one solid epoxy particle, at least one epoxy resin curing agent, and at least one type of proppant particles. The methods comprise deploying a fluid composition into a wellbore extending to a subterranean geological formation using pressure sufficient to form a fracture in the subterranean geological formation, and immobilizing at least a portion of the solid epoxy particles and proppant particles in the fracture. Embodiments of the fluid compositions are useful for increasing hydrocarbon production from subterranean geologic formations, and/or controlling solids migration in such formations.
