Abstract
A method for using an extended-life settable composition is disclosed. The method includes providing an extended-life settable composition comprising red mud, calcium hydroxide, water, and a cement set retarder. The method further includes activating the extended-life settable composition. The method additionally includes introducing the extended-life settable composition into a subterranean formation and allowing the extended-life settable composition to set in the subterranean formation.
Claims9
An extended-life settable composition comprising:
- red mud;
- calcium hydroxide;
- water;
- and
- a cement set retarder,
- wherein the red mud is present in a red mud-to-calcium hydroxide weight ratio of about 3:1 to about 5:1, wherein the red mud is a product of refining bauxite ore, the refining comprising sodium hydroxide digestion of the bauxite ore followed by filtration of solid impurities generated by the digestion, and wherein the extended-life settable composition is capable of remaining in a pumpable fluid state for 1 day or longer at 80° F.
A system comprising:
- an extended-life settable composition that is capable of remaining in a pumpable fluid state for 1 day or longer at 80° F.;
- wherein the extended-life settable composition comprises red mud, calcium hydroxide, water, and a cement set retarder, wherein the red mud is present in a red mud-to-calcium hydroxide weight ratio of about 3:1 to about 5:1, and wherein the red mud is a product of refining bauxite ore, the refining comprising sodium hydroxide digestion of the bauxite ore followed by filtration of solid impurities generated by the digestion;
- and
- a cement set activator for at least one of activating and accelerating the extended-life settable composition.
