The flow of a fluid may be diverted from a high permeability zone to a low permeability zone of a subterranean formation or well sections may be temporarily isolated by use of particles comprising a mixture of (i) at least one bi-phenyl compound of Compound I, (ii) one mellitic derivative of Compound II, (iii) one chelating agent of Compound III, (iv) one polymer of Compound IV, and (v) an internal breaker for the diverting agents and other additives like gels, foams, acids, brines and various other treatment chemicals.

Compositions useful for diverting or stopping fluids in subterranean operations

During 'fracking' operations, proppants are used to keep open the fissures that are created, and stimulation fluids are often injected into the subterranean hydrocarbon-bearing geological formations to assist in capturing released hydrocarbons. However, because fissure surfaces formed in subterranean hydrocarbon-bearing geological formations from fracking tend to be hydrophobic, both introduced stimulation fluids and the hydrocarbons from the subterranean hydrocarbon-bearing geological formations tend to adhere to the fissure surfaces. The addition of a gemini surfactant appears to reduce the hydrophobic nature of the geological structure's fissure surfaces, thereby wetting surfaces of indigenous rock and/or introduced proppant surfaces. The addition of the gemini surfactant results in an increase of the fluid flow through the subterranean hydrocarbon-bearing geological formations, thereby enhancing of recovery of hydrocarbons and introduced stimulation fluids.

Method for enhancing fluid recovery from subsurface reservoirs

It is common to require oil-well treating chemicals to be introduced into subterranean geological formations over the well's drilling, stabilization and extraction phases. The timely controlled and uniform release of such chemicals throughout the fluid bed vastly enhances their effectiveness. A method is disclosed for introducing such oil-well treating chemicals throughout the subterranean formation by encapsulating the chemicals within engineered composites, which are introduced into the subterranean formations along with the other fluids. These engineered composites are formed to slowly release the oil-well treating chemicals once they are in the subterranean formations as the engineered composites slowly dissolve.

Controlled release of well treatment agents into oil wells

Fracturing (or fracking fluids) used to enhance hydrocarbon extraction for subterranean rock formations may impede the recovery of the targeted hydrocarbons. Thus, it is common practice to inject a breaker into the subterranean rock formation to reduce the viscosity of the fracking fluids. The chemicals used to reduce the viscosity, called breakers, need to act after the tracking fluids have opened the pores in the subterranean rock formations, but before hydrocarbon extraction is hindered. A novel method for controlling the release of the breakers is disclosed. This method comprises encapsulating the breakers within a capsule comprised of water-soluble polymers and water-insoluble polymers. The water-soluble polymers are dissolved controllably by fluids within the well, allowing the breakers to react with the fracking fluids.
