Abstract:

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.

E21B 37/00

Abstract:

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.

Appl. No.:

Inventors:

Ambrish Kamdar - SUGARLAND TX, US

International Classification:

E21B 37/00

Abstract:

Fracturing fluids (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 fracking 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 consisting essentially of water-soluble polymer components and water-insoluble polymer components. The water-soluble polymer component dissolves controllably by fluids within the well, allowing the breakers to react with the fracking fluids.

Abstract:

A novel method for a controlled release of oil well treating compositions is revealed. The “engineered composite” are formed by mixing well treatment agents with an impervious substrate that exhibit low solubility in water and oil. The engineered composite is introduced in to subterranean wells along with a carrier, fluid to release well, treatment agents over extended periods of time.

Abstract:

Acids, such as hydrochloric acid, are pumped down in to the formation in acidizing treatments of oil & gas wells, thru metal pipes/tubing. Corrosion Inhibition of these metal surfaces (pipes, tubing, etc) has been extensively studied. Most known acid corrosion inhibitors (ACI) and acid corrosion inhibitors currently used in the oilfield contain ingredients that are an environmental concern or have poor Health, Safety and Environmental (HSE) characteristics. This invention relates to the discovery of a Novel Acid Corrosion Inhibitor. Aromatic Nitriles, especially Cinnamyl Nitrile, when added to the acid in effective amounts, offers acceptable rates of corrosion inhibition.Cinnamyl Nitrile can be substituted in place of ingredients that have poor HSE characteristics, to improve the HSE characteristics of acid corrosion inhibitors, without sacrificing corrosion inhibition performance. Cinnamyl Nitrile can also be added to formulations of know acid corrosion inhibitors being used in the oilfield to improve their corrosion inhibition performance.
