摘要: A method of increasing a rate penetration when drilling as compared to with baseline fluid comprising an API-grade barite weighting agent and having given sag, settling rate, density, flow pressure drop through wellbore, comprising: circulating base micronized the wellbore; wherein is characterized equivalent or lower sag than fluid; at higher rate; results in wellbore.
