Abstract

See full text

A proppant for a well treatment fluid includes discrete particles of a substrate, such as sand, coated with a resin comprising a product of the Maillard reaction between a carbohydrate and an amine and/or an ammonium compound. Different resins, in particular thermoplastic or thermosetting resins, may be blended with Maillard reaction products or applied to the substrate as separate layers. The proppant may be included in a fracturing fluid, which is injected into a subterranean formation and used to stimulate hydrocarbon production from the subterranean formation.
