SETTABLE SPACER FLUIDS COMPRISING PUMICITE AND METHODS OF USING SUCH FLUIDS IN SUBTERRANEAN FORMATIONS

摘要

Methods and compositions for the treatment of subterranean formations, and more specifically, treatment fluids containing pumicite and methods of using these treatment fluids in subterranean formations, are provided. An example of a method is a method of displacing a fluid in a well bore. Another example of a method is a method of separating fluids in a well bore in a subterranean formation. An example of a composition is a settable spacer fluid comprising pumicite, an activating agent, and a base fluid.
