  • Patent number: 9988306
    Abstract: A variety of methods and compositions for cementing with set-delayed cement. In one embodiment a method comprises providing a set-delayed cement composition comprising a hydraulic cement, water, and a primary retarder. The method further comprises activating the set-delayed cement composition through a retarder exchange whereby, a secondary retarder is added to the set-delayed cement composition to produce an activated cement composition. The activated cement composition is then allowed to set.

  • Patent number: 9840659
    Abstract: Methods including deactivation and activation of permeability modifiers for use in subterranean formation operations. A first treatment fluid may be introduced into a subterranean formation having a first treatment zone having a first aqueous permeability value, the first treatment fluid comprising a first aqueous base fluid and a deactivated permeability modifier. The deactivated permeability modifier may be adsorbed onto a surface of the first treatment zone. A second treatment may thereafter be introduced into the subterranean formation, the second treatment fluid comprising a second aqueous base fluid and a cyclodextrin compound. The second treatment fluid may contact the deactivated permeability modifier to activate the permeability modifier by complexing the deactivating surfactant with the cyclodextrin compound, thereby forming an activated permeability modifier adsorbed onto the surface of the first treatment zone and reducing the aqueous permeability of the first treatment zone.
