Title: Consolidatable gravel pack method

A method is described for forming a consolidated gravel pack in a washed-out cavity adjacent to a producing well penetrating a subterranean oil formation comprising the steps of: (a) forming a quantity of resin coated gravel comprising granular mineral particles including gravel, the gravel particles being coated with a resin fluid containing a polymerizable oligomer of furfuryl alcohol resin, a catalyst comprising an oil soluble, very slightly water soluble organic acid and an ester of a weak organic acid to consume water produced by the polymerization of resin, the polymer coated gravel comprising a sticky solid material; (b) preparing an aqueous saline carrier fluid comprising water which is from 70 to 100% saturated with sodium chloride; (c) suspending the resin-coated gravel in the carrier fluid, forming a fluid mixture of resin-coated gravel and carrier fluid; (d) introducing the fluid mixture comprising the resin coated gravel particles suspended in the aqueous saline carrier fluid into the washed-out cavity of the formation adjacent to the producing well and shutting in the well for sufficient period of time to allow polymerization of the resin, forming the permeable gravel pack in the washed-out cavity of the formation.
