Abstract: The present invention relates to a method for measuring a cement slurry property, such as static gel strength or yield stress, under at least one downhole condition, and apparatuses and systems for performing the same. In some embodiments, the method includes detecting a downward force exerted by a curing cement slurry under at least one downhole condition within a vessel movable along a vertical axis proportionally to the downward force. A surface substantially nonmovable along the vertical axis is disposed at least partially within the cement slurry. The method also includes determining at least one property of the cement slurry from the detected downward force.

Abstract: Of the many compositions and methods provided herein, one method includes providing a settable fluid that comprises an aqueous-based medium, a lime composition, and a cementitious blend that comprises metakaolin particulates and aluminosilicate particulates, wherein the cementitious blend is essentially free of Portland cement; introducing the settable fluid into a wellbore penetrating a subterranean formation that comprises a corrosive component; and allowing the settable fluid to set therein.
