Method of coating particulate solids with an infusible resin

摘要: Hydraulic fracturing is a common method of increasing the production from an oil or gas well, wherein desired section earth formation parted fractured by application hydraulic fluid pressure. Sand other particulate material generally added to as propping agent pack and fill fracture, thus hold it open when applied pressure dissipated. The consists in mixing solids with liquid containing resin-forming composition furfuryl alcohol, alcohol resins, mixtures, heating coated bath which may contain catalyst for resin cure on individual particles solids. Radioactive materials be incorporated coating. (16 claims)
