摘要：
Apparatus and methods for determining suitable displacement fluids for use in subterranean cementing operations, and methods of cementing that use such displacement fluids, are provided. Examples of apparatus include apparatus for evaluating fluids. An example of a system is a system for inverting an oleaginous-external/aqueous-internal fluid in a well bore in a subterranean formation.
