Wald, J M

A reservoir formation encountered by a cased and perforated well, which is unconsolidated or is likely to become unconsolidated, is treated by injecting a sand consolidating resin-forming solution. The resin solution used is one from which a self-curing partially polymerized epoxy resin is precipitated after the solution has been displaced into the well and into the sand. The resin solution is injected so that it both permeates a selected portion of the sand that is immediately adjacent to the borehole and fills the perforated interval of the casing, i.e., the portion that is immediately adjacent to and in fluid communication with the sand.
