Claim:
1. A method of cementing in a subterranean formation comprising: introducing a transition fluid into the subterranean formation, wherein the transition fluid is an invert emulsion and comprises: introducing a cement composition into the subterranean formation, wherein the step of introducing the cement composition is performed after the step of introducing the transition fluid and wherein the cement composition comprises cement and water; and contacting at least a portion of the cement composition with the transition fluid to provide a contaminated cement composition in the subterranean formation, wherein the contaminated cement composition comprises at least a 20% increase in compressive strength compared to the same cement composition contaminated with a fluid comprising the same hydrocarbon liquid and aqueous liquid of the transition fluid, but which does not comprise the same surfactant and the calcium aluminate cement of the transition fluid, and wherein the contamination is 10% by volume of the cement composition.
