MULTIFUNCTIONAL PROPPANT FOR FRACTURING APPLICATIONS

摘要

Multifunctional proppants made up of proppant particles that are at least partially coated by a biocide, a breaker, and a cross-linking agent. These components can be positioned around the proppant particles so they function in a sequential or time-release manner. The multifunctional proppants can be provided in fracturing fluids to form or maintain one or more fractures in a subterranean zone penetrated by a well bore and which can minimize or inhibiting bacterial growth.
