Abstract
Disclosed are spacer fluids and methods of use in subterranean formations. Embodiments may include use of consolidating spacer fluids in displacement of drilling fluids from a well bore annulus.
Claims28
A consolidating spacer fluid for separating drilling fluid and a cement composition in a well bore, comprising:
- water;
- and
- at least one additive selected from the group consisting of kiln dust, gypsum, fly ash, bentonite, hydroxyethyl cellulose, sodium silicate, a hollow microsphere, gilsonite, perlite, a gas, an organic polymer, a biopolymer, latex, ground rubber, a surfactant, crystalline silica, amorphous silica, silica flour, fumed silica, nano-clay, salt, fiber, hydratable clay, rice husk ash, micro-fine cement, metakaolin, zeolite, shale, pumicite, Portland cement, Portland cement interground with pumice, barite, slag, lime, and any combination thereof;
- and
- wherein the consolidating spacer fluid has a zero gel time of about 4 hours or less under predetermined well bore conditions.
A consolidating spacer fluid for separating, a drilling fluid and a cement composition in a well bore, comprising:
- water;
- cement kiln dust;
- and
- wherein the consolidating spacer fluid has a zero gel time of about 4 hours or less under predetermined well bore conditions.
A consolidating spacer fluid for separating, a drilling fluid and a cement composition in a well bore, comprising:
- water,
- a partially calcined kiln feed comprising SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Na2O, and K2O, and
- optionally, an additive selected from the group consisting of gypsum, fly ash, bentonite, hydroxyethyl cellulose, sodium silicate, a hollow microsphere, gilsonite, perlite, a gas, an organic polymer, a biopolymer, latex, ground rubber, a surfactant, crystalline silica, amorphous silica, silica flour, fumed silica, nano-clay, salt, fiber, hydratable day, rice husk, ash, micro-fine cement, metakaolin, zeolite, shale, pumicite, Portland cement, Portland cement interground with pumice, barite, slag, lime, and any combination thereof;
- and
- wherein the consolidating spacer fluid has a zero gel time of about 4 hours or less under predetermined well bore conditions.
