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.
