Abstract: By the addition of wollastonite to slag based cements, such as those formed when converting drilling fluids to cementitious materials in oil and gas well applications, the flexural strength of the cementitious material is improved. The method involves forming a pumpable slurry of drilling fluid, blast furnace slag and the fibrous mineral, wollastonite. The slurry is then activated by the addition of such activators as sodium hydroxide and soda ash and is pumped into the well bore to a desired location and is allowed to solidify.

Abstract: Aluminum silicate and/or fibrous mineral-containing cement compositions for cementing wellbores in high stress environments, such as for cementing multi-lateral completions. The cement compositions typically comprise a mixture of a reactive aluminum silicate and/or fibrous mineral such as wollastonite, and may include one or more other additives. The cement compositions may be used to produce set cements offering improved compressive strength, flexural strength, and/or tensile strength over conventional cement compositions.

Abstract: This invention relates to a cement composition for cementing oil, gas and geothermal wells comprising: a cement; and an additive comprising a blend of a sodium silicate; water; a carrageenan suspending agent; a sodium polyacrylate; an AMPS terpolymer; a dispersant; and a cellulosic water soluble polymer. The dispersant may comprise a sulfonated naphthalene formaldehyde condensate or a sulfonated ketone acetone formaldehyde condensate. The cellulosic water soluble polymer may comprise HEC or CMHEC. The invention can also function to reduce the occurrence of gas channelling and stabilize foam created by adding nitrogen gas to cement.

Abstract: Aluminum silicate-containing cement slurries for cementing wellbores in deepwater and cold environments, or in wellbores susceptible to fluid intrusion. The aluminum silicate-containing slurries may also be used as high strength, low density cements for wellbore cementing applications under a variety of conditions. The cement slurries typically comprise a mixture of a reactive aluminum silicate and hydraulic cement, and may include one or more other additives. The cement slurries may optionally be foamed using a foaming agent and energizing phase.

Abstract: Cement compositions containing low reactivity materials are disclosed. The compositions are useful in conditions involving high temperatures, high pressures, and tectonic forces such as oil and gas wells. The cement compositions display increased compressive strength, flexural strength, and tensile strength. Fractures appear to occur in a non-linear fashion between the Interfacial Transition Zone (ITZ) of the particles, rather than in a straight line such as those observed in conventional cement materials.

Abstract: Cement compositions including mixtures of substantially elastic material and cement that may be formulated exhibit reduced bulk volume shrinkage during curing as compared to conventional cement compositions. In one application, such cement compositions may be used for cementing in substantially closed system, such as the interior of a mold used for producing preformed concrete items.
