  • COMPOSITIONS AND METHODS FOR USE OF PROPPANT SURFACE CHEMISTRY TO IMPROVE PROPPANT CONSOLIDATION AND FLOWBACK CONTROL
    Publication number: 20140318775
    Abstract: The present invention relates to methods for hydraulically fracturing a subterranean formation to improve the production rates and ultimate recovery by contacting unconsolidated resin-coated proppant particulates residing in a propped fracture with a reactive crosslinker in order to form a consolidated proppant pack. The present invention also relates to methods for use in water injection wells to consolidate the resin-coated proppant particulates in a gravel packed or frac packed region of a wellbore.

  • COMPOSITION AND METHOD FOR HYDRAULIC FRACTURING AND EVALUATION AND DIAGNOSTICS OF HYDRAULIC FRACTURES USING INFUSED POROUS CERAMIC PROPPANT
    Publication number: 20140262247
    Abstract: A composition and method for hydraulically fracturing an oil or gas well to improve the production rates and ultimate recovery using a porous ceramic proppant infused with a chemical treatment agent is provided. The chemical treatment agent may be a tracer material that provides diagnostic information about the production performance of a hydraulic fracture stimulation by the use of distinguishable both water soluble and hydrocarbon soluble tracers. The tracer can be a biological marker, such as DNA. The porous ceramic proppant can be coated with a polymer which provides for controlled release of the chemical treatment agent into a fracture or well bore area over a period of time.
