Patent Images
1. A method of cementing a wellbore in a subterranean formation, comprising:
- formulating a non-Portland base cement composition that may be suitable for long-term zonal isolation;
preparing the non-Portland base cement composition;
determining a density of the non-Portland base cement composition and adjusting the density as needed to within an optimized density range to form a first optimized cement composition;
determining the percentage of tensile strength relative to compressive strength of the first optimized cement composition;
adjusting the percentage of tensile strength relative to compressive strength of the first optimized cement composition as needed to within an optimized percentage of tensile strength relative to compressive strength range to produce an optimized cement composition; and
placing the optimized cement composition in the wellbore.
