ABSTRACT:
Loose particles are consolidated, e.g., to prevent them from falling into well bores in producing wells, by contacting the loose particles with a solution having a pH above 7 containing water-soluble polymer, e.g., polyvinyl alcohol and hydroxyethyl cellulose, and a polyisocyanurate salt and maintaining said contact for a time sufficient to cause the formation of a consolidating matrix.
