Zusammenfassung:A method comprises controlling an operating pressure of a fluid from a borehole. The fluid comprises solids and entrained gas. The method further comprises 5 removing at least a portion of the entrained gas from the fluid at an upstream location. The method further comprises removing residual entrained gas from the fluid at a downstream location. The method further comprises separating at least a portion of the solids from the fluid. The method further comprises circulating the separated fluid back to the borehole. Separating of solids occurs after the removing of entrained 10 gases from the fluid at the downstream location. rc rC
