摘要:
A method of improving the flow properties of at least one dry particulate cementitious or non-cementitious material comprises dry-blending a particulate flow enhancing additive with said cementitious or non-cementitious material, said additive being comprised of a particulate solid absorbent material having a flow inducing polar-molecule-producing chemical absorbed thereon. A method of transporting the material comprises placing the blended material in a storage tank, transporting the storage tank to a location of use and conveying the blended material out of the storage tank.
摘要:
A subterranean zone is sealed to reduce the uncontrolled flow of fluids into and out of the zone, by introducing a sealing composition into the well bore fluids so that it rapidly converts to a high viscosity sealing mass therein and is deposited in said zone to seal it.

Oil-based compositions for sealing subterranean zones are basically comprised of oil, a hydratable polymer, an organophilic clay and a water-swellable clay.
