Abstract
Extended-life cement compositions are provided and, more particularly, extended-life cement compositions are provided that comprise a cementitious component comprising red mud solids and hydraulic cement. A method of cementing may comprise providing an extended-life cement composition comprising a cementitious component, water, and a cement set retarder, wherein the cementitious component comprises red mud solids and a hydraulic cement; activating the extended-life cement composition; introducing the extended-life cement composition into a subterranean formation; and allowing the extended-life cement composition to set in the subterranean formation.
Claims19
A method of cementing comprising:
- providing an extended-life cement composition comprising a cementitious component, water, and a cement set retarder, wherein the cementitious component comprises red mud solids and a hydraulic cement, wherein the red mud solids are present in an amount of about 50% to about 90% by weight of the cementitious component, and wherein the hydraulic cement is present in an amount of about 10% to about 50% by weight of the cementitious component;
- activating the extended-life cement composition;
- introducing the extended-life cement composition into a subterranean formation;
- and
- allowing the extended-life cement composition to set in the subterranean formation.
A cement composition comprising:
- a cementitious component comprising red mud solids and a hydraulic cement, wherein the red mud solids are present in an amount of about 50% to about 90% by weight of the cementitious component, and wherein the hydraulic cement is present in an amount of about 10% to about 50% by weight of the cementitious component;
- water;
- and
- a cement set retarder,
- wherein the cement composition is an extended-life cement composition that is capable of remaining in a pumpable fluid state for about 1 day or longer at 80° F.
A system for cementing comprising:
- an extended-life cement composition that is capable of remaining in a pumpable fluid state for about 1 day or longer at 80° F., wherein the extended-life cement composition comprises a cementitious component, water, and a cement set retarder, wherein the cementitious component comprises red mud solids and a hydraulic cement, wherein the red mud solids are present in an amount of about 50% to about 90% by weight of the cementitious component, and wherein the hydraulic cement is present in an amount of about 10% to about 50% by weight of the cementitious component;
- and
- a cement set activator for activating the extended-life cement composition.
