ABSTRACT:
A method of cementing a wellbore in a subterranean formation, comprising formulating a cement composition that may be suitable for long-term zonal isolation of the subterranean formation by evaluating a subterranean formation, preparing a base cement composition, determining the compressive strength of the base cement composition, determining the tensile strength of the base cement composition, and adjusting the ratio of compressive strength to tensile strength as need to within a first optimizing range to form a first optimized cement composition, and placing the optimized cement composition in the wellbore.
