Abstract: A method comprises controlling an operating pressure of a fluid from a borehole. The fluid comprises solids and entrained gas. The method further comprises 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 gases from the fluid at the downstream location.

Abstract: A modularly segmented apparatus for precise borehole pressure control, removing waste from borehole fluid, and recirculating the cleaned borehole fluid includes a pressure control section, a gas separator section, and a waste management section. In the pressure control section, a pressure manifold interconnects a plurality of chokes. A plurality of valves are used to direct the contaminated fluid through one of the chokes, which maintains a precise and predetermined pressure in the system. The manifold, chokes, and valves are mounted on a skid for easy transport. In the gas separator section, a gas separator is used to remove a majority of the gases present in the contaminated borehole fluid. In the waste management section, a vibratory separator removes large solid contaminants from the degassed fluid. The solids are directed to a solids collection container for further treatment or disposal. The fluid is directed to a first pit, which may be one partitioned are of a larger collection tank.
