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.
