Abstract
Disclosed is a method for controlling sand flow in an producing well by forming a permeable consolidated gravel pack. Gravel is coated with a resin such as an oligomer of furfuryl alcohol containing an ester and as a catalyst an oil soluble, slightly water soluble organic acid such as anthranilic acid. The resin coated gravel is suspended in a carrier fluid comprising saturated brine and optionally a viscosity increasing polymer. The fluid comprising resin coated gravel and the carrier fluid are pumped through the well into the formation adjacent to the producing well. Heat or pressure cause joining of adjacent coated gravel to form the consolidated gravel pack.
