Abstract
Cement compositions comprising set retarder compositions, and methods of using the cement compositions in surface and subterranean applications are provided. In some embodiments, cement compositions are provided that comprise a hydraulic cement comprising an API cement, water, and a set retarder composition, the set retarder composition comprising an acrylamide polymer derivative; and an iron compound. In other embodiments, cement compositions, set retarder compositions, methods of cementing, methods of retarding the set time of a cement composition, and methods of preparing a cement composition are provided.
Claims103
A method of cementing in a subterranean formation comprising:
- providing a cement composition comprising a cement comprising an API cement, water, and a set retarder composition, the set retarder composition comprising:
- an acrylamide polymer derivative, and an iron compound present in the range of at least about 0.24% by weight of the set retarder composition;
- placing the cement composition into the subterranean formation;
- and
- permitting the cement composition to set therein.
A method of cementing in a subterranean formation comprising:
- providing a cement composition comprising a cement comprising a cement, water, and a set retarder composition, the set retarder composition comprising:
- a lignin-based retarder, and an iron compound;
- placing the cement composition into the subterranean formation;
- and
- permitting the cement composition to set therein.
A method of retarding the set time of a cement composition comprising:
- adding a set retarder composition to a cement composition, the set retarder composition comprising an acrylamide polymer derivative, and an iron compound;
- present in the range of at lest about 0.24% by weight of the set retarder composition;
- placing the cement composition into the subterranean formation;
- and
- permitting the cement composition to set therein.
A method of preparing a cement composition comprising:
- preblending a set retarder composition that comprises an acrylamide polymer derivative and an iron compound present in the range of at lest about 0.24% by weight of the set retarder composition;
- and
- preparing a cement composition that comprises the set retarder composition, a cement, and water, subsequent to preblending the set retarder composition.
