REDUCED ABRASIVENESS WITH MICRONIZED WEIGHTING MATERIAL. |
摘要 |
<p>A method of prolonging the average lifespan of downhole tools that includes circulating the wellbore fluid comprising a base fluid and at least one of a micronized weighting agent and a dispersant coated weighting agent through the wellbore; wherein the wellbore fluid is characterized as having at least one of an equivalent weight, an equivalent or lower settling rate, and an equivalent or lower sag than a baseline wellbore fluid comprising a base fluid and an API-grade barite weighting agent; and wherein the wellbore fluid reduces abrasive wear of the downhole tool as compared to drilling with the baseline wellbore fluid is disclosed.</p> |
