Abstract
Disclosed herein is a method of servicing a wellbore comprising the steps of preparing a dry cement blend comprising a base cement and a crystalline component wherein the dry cement blend is based on an initial dry cement blend formulation, obtaining a diffraction pattern of a sample of the dry cement blend, generating a model diffraction pattern, refining the model diffraction pattern using a structural refinement method, determining the type and amount crystalline components present in the dry cement blend, generating a final dry cement blend formulation, and comparing the initial dry cement blend formulation to the final dry cement blend formulation.
