USE OF NEUTRAL-DENSITY PARTICLES TO ENHANCE BARITE SAG RESISTANCE AND FLUID SUSPENSION TRANSPORT
摘要
<p>The present invention relates to particles that are useful for enhancing hindered settling in suspensions. One embodiment of the present invention provides a method of providing a subterranean treatment fluid including a base fluid and a weighting agent having a first average settling velocity; and a neutral-density particle; and mixing the subterranean treatment fluid with the neutral-density particle thereby reducing the weighting agent to a second average settling velocity.</p>
