SILICA-ENCAPSULATED EXPANSION AGENTS FOR WELL CEMENTING
A subterranean well cementing slurry is prepared by coating particles of an expanding agent with silica, and combining the coated particles with water and hydraulic cement in any order. The slurry is placed around a tubular member in an annular region in the well where it is allowed to set and harden, and at least some of the expansion is delayed until after the cement is at least partially set.
