Abstract
The present invention includes methods of cementing in subterranean formations using cement kiln dust in compositions having reduced Portland cement content. An embodiment of a method comprises placing a sealant composition that comprises cement kiln dust and is essentially free of Portland cement in a subterranean formation; and allowing the sealant composition to set.
Claims32
A method comprising:
- placing a sealant composition that comprises cement kiln dust and is essentially free of Portland cement in a subterranean formation;
- and
- allowing the sealant composition to set.
A method comprising:
- placing a hydraulic sealant composition that comprises cement kiln dust and water and is essentially free of Portland cement in a subterranean formation;
- and
- allowing the hydraulic sealant composition to set.
A method comprising:
- placing a hydraulic sealant composition in a subterranean formation, wherein the hydraulic sealant composition consists essentially of:
- pumicite,
- lime,
- cement kiln dust,
- water, and
- an additive selected from the group consisting of a strength-retrogression additive, a set accelerator, a set retarder, a weighting agent, a lightweight additive, a gas-generating additive, a mechanical property enhancing additive, a lost-circulation material, a filtration-control additive, a dispersant, a fluid loss control additive, a defoaming agent, a foaming agent, an oil-swellable particle, a water-swellable particle, a thixotropic additive, a gas, and any combination thereof;
- and
- allowing the hydraulic cement composition to set.
