WELL FLUID AND METHOD USING HOLLOW PARTICLES

摘要

The present invention relates to improved well fluids that include hollow particles, and to methods of using such irnproved well fluids in subterranea n cementing operations. The present invention provides methods of cementing, methods of reducing annidar pressure, and well fluid compositions. While the compositions and methods of the present invention are useful in a variety of subterranean applications, they may be particularly useful in deepwater offshore cementing operations.
