摘要： Proppants for use in fractured or gravel packed/frac packed oil and gas wells are provided with a contaminant removal component to remove one or more of the contaminants found in subterranean water/hydrocarbon from a production well. The water/hydrocarbon cleaning proppant solids may be used as discrete particles in a proppant formulation, as a coating on proppant solids in pores of a porous proppant solid or as part of the proppant's internal structure. The contaminant removal component removes contaminants, especially dissolved contaminants, in the subterranean water or hydrocarbon before the water/hydrocarbon leaves the well. For those contaminant removal components that can be regenerated, such as ion exchange resins, a measured quantity of an acidic regeneration solution can be injected into the fractured stratum for regeneration and recovered when the well resumes production.

摘要： Proppants for hydraulic fracturing of oil and gas wells have a polymeric coating that is strengthened with reinforcing particulates that are reactive with, or chemically bonded to, the polymeric proppant coating. Preferably, these particulates are added into the coating during the coating process. In one embodiment, functionalized particulates are used that become grafted into the polymer of the proppant coating through the chemical functionality imparted to the particulates. If non-functionalized particulates are used, a coupling agent is preferably added to enhance the bond strength between the added particulates and the polymeric matrix of the proppant coating.
