Method for forming a consolidated gravel pack
Patent
·
OSTI ID:6170371
A gravel pack slurry contains an aqueous carrier fluid, an epoxy resin, a curing agent for the resin, a solvent for the resin and curing agent, a finely divided particulate material, a particular quaternary ammonium halide, and a coupling agent to promote bonding of the resin to the particulate. Optionally, the slurry may contain a thickening or gelling agent for the water to enhance its solids carrying capacity and an agent to break the gel after its purpose has been served. The slurry is suitable for placing a permeable, consolidated gravel pack adjacent to an incompetent subterranean formation. It does not require an oil-based carrier and can easily be prepared in the field by adding the particulate directly to the aqueous carrier without precoating the particulate with the resin. 21 claims.
