    摘要： Improved methods and compositions for coating proppant particles with a hardenable resin composition, suspending the coated proppant particles in a fracturing fluid, and consolidating the proppant particles after being placed in fractures into permeable masses are provided. These methods and compositions are especially suitable for low temperature well, specifically those around the 60° F. to 225° F. ranges. Preferably, a liquid hardenable resin component is mixed with a liquid hardening agent component on-the-fly to form a hardenable resin composition. The hardenable resin composition is coated onto proppant particles on-the-fly that are conveyed from a source thereof to form resin-coated proppant particles in real-time. The resin-coated proppant particles are suspended in the fracturing fluid to be utilized down hole.

    摘要： The present invention relates to methods for stabilizing an unconsolidated or weakly consolidated zone of a subterranean formation. One embodiment provides a method of stabilizing a subterranean formation comprising the steps of placing a gelable liquid composition into the subterranean formation, wherein the gelable liquid composition is capable of forming a gelled substance after placement; and, allowing the gelable liquid composition to convert into a gelled substance that stabilizes unconsolidated or weakly consolidated particles within the subterranean formation. Another embodiment provides a method of stimulating production from a subterranean formation comprising the steps of placing a gelable liquid composition into the subterranean formation; allowing the gelable liquid composition to convert into a gelled substance; creating at least one fracture in the subterranean formation extending from the well bore, through the gelled substance, and into an untreated zone of the subterranean formation; depositing proppant into at least one such fracture.
