Abstract: Capsules, systems and methods for delivering chemical components to multiphase environments are disclosed. The systems and methods utilize delivery capsules within which the chemical components are encapsulated. The chemical components may be corrosion inhibitors or biocides and the multiphase environment an oil/water environment, for example, within an oil transport pipeline. The systems and methods allow delivery of the capsules to targeted areas of the multiphase environment, for example, to a water phase or a water/metal interface.

Abstract: Particulate compositions including a plurality of particles containing oil field chemicals encapsulated in a water soluble, water swellable, or water degradable matrix material are disclosed. The oil field chemicals may be corrosion inhibitors and the particulate composition may be prepared by spray drying mixtures of matrix material and oil field chemicals. The particulate compositions are designed to efficiently deliver the chemicals to the water phase of a multiphase environment, such as an oil/water environment.
