MODIFIED PARTICULATE WEIGHTING AGENTS AND METHODS OF USING THE SAME.

摘要

In subterranean operations, additives used in treatment fluids such as drilling and cementing fluids include weighting agents; a method includes the steps of providing a treatment fluid for use in a subterranean formation comprising a weighting agent, the weighting agent comprising a micronized metal oxide particle and a polymer linked to the metal oxide particle, the method including introducing the treatment fluid into the subterranean formation.
