A method comprising:
- introducing a settable composition into a subterranean formation, wherein the settable composition comprises:
- a cementitious component comprising:
- a hydraulic cement, and
- cement kiln dust;
- a swellable particle;
- and
- water;
- and
- allowing the settable composition to set in the subterranean formation.
A method comprising:
- introducing a settable composition into an annulus between a pipe string and a subterranean formation, wherein the settable composition comprises:
- a cementitious component comprising:
- a hydraulic cement, and
- cement kiln dust;
- a swellable particle;
- and
- water;
- and
- allowing the settable composition to set in the annulus.
A method comprising:
- introducing a settable composition into an annulus between a pipe string and a subterranean formation, wherein the settable composition comprises:
- a cementitious component comprising:
- a hydraulic cement in an amount of about 25% to about 75% by weight of the cementitious component, and
- cement kiln dust in an amount of about 25% to about 75% by weight of the cementitious component;
- a swellable particle in an amount of about 5% to about 25% by weight of the cementitious component and comprising at least one swellable polymer selected from the group consisting of a block copolymer of styrene butadiene rubber, a sodium salt of polyacrylic acid, and combinations thereof;
- and
- water;
- and
- allowing the settable composition to set in the annulus.
