Abstract
Subterranean treatment operations, and more particularly, methods of cementing subterranean formations using cement compositions including maltodextrin, are provided. An example of a method of the present invention is a method of cementing a subterranean formation, comprising: providing a cement composition comprising water, a hydraulic cement, and an additive comprising maltodextrin; placing the cement composition in a subterranean formation; and permitting the cement composition to set in the formation.
Claims25
A method of cementing a subterranean formation, comprising:
- providing a cement composition comprising water, a hydraulic cement, and an additive comprising maltodextrin and a chlorinated carbohydrate;
- placing the cement composition in a subterranean formation;
- and
- permitting the cement composition to set in the formation.
A method of cementing a subterranean formation, comprising:
- providing a cement composition comprising water, a hydraulic cement, and an additive comprising maltodextrin, a chlorinated carbohydrate, and an organic acid, the additive being present in the cement composition in an amount in the range of from about 0.01% to about 5% by weight of the hydraulic cement;
- placing the cement composition in a subterranean formation;
- and
- permitting the cement composition to set in the formation.
A method of cementing a subterranean formation, comprising:
- providing a cement composition comprising water, a hydraulic cement, and an additive comprising maltodextrin, a chlorinated carbohydrate, and tartaric acid, wherein the maltodextrin is present in the additive in an amount in the range of from about 0.01% to about 99.9% by weight, and the tartaric acid is present in the additive in an amount in the range of from about 0.01% to about 99.9% by weight;
- placing the cement composition in a subterranean formation;
- and
- permitting the cement composition to set in the formation.
A method of cementing a subterranean formation, comprising:
- providing a cement composition comprising water, a hydraulic cement, and an additive consisting essentially of maltodextrin;
- placing the cement composition in a subterranean formation;
- and
- permitting the cement composition to set in the formation.
