Consolidatable gravel pack method
Patent
·
OSTI ID:7151996
Sand or similar material coated with a polymerizable resin and catalyst is suspended in a viscous fluid carrier. Such a composition is useful for introduction into a wellbore to effect gravel packing of washed-out cavities surrounding the wellbore. The viscous fluid carrier serves to maintain a heterogeneous suspension of sand as the composition is flowed down through the wellbore, so as to prevent premature settling of sand into gradient layers and voids. The fluid carrier includes a polymeric thickener and a small concentration of viscosity-enhancing agent, such as a dye. The viscosity-enhancing agent is effective to alter the configuration of polymeric thickener so as to enhance the viscosity imparted thereby. The sand or gravel included in the gravel packing composition is coated with a polymerizable resin and latent catalyst. At formation condition, the resin polymerizes and links together adjacent sand particles thereby forming a permeable consolidated structure which serves to reestablish washed-out zones near a wellbore. Corresponding methods for utilizing the compositions in gravel packing washed-out cavities surrounding a borehole are disclosed.
