Abstract: A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

Abstract: A screening system including a vibratory screen separator having a resiliently mounted frame with a low frequency vibratory drive coupled to that frame. A taut screen is rigidly mounted in the frame and a vibration transmitter assembly is resiliently mounted to the frame and fixed to the taut screen. The vibration transmitter includes a planar ring compressed against the taut screen and vibration generators. The vibration generators are air turbines with eccentric weights. The frame includes support elements extending from the cylindrical outer housing sections of the separator to a concentrically mounted support ring. Compressed air is provided to the turbines through hollow structure within the frame. Valves control exhaust from the turbines. The low frequency vibratory drive operates in a range of about 8 Hz to 30 Hz while the vibration generators provided by the air turbines operate in a range of about 275 Hz to 600 Hz.

Abstract: Apparatus and methods for degassing and analyzing drilling fluid discharged from a wellbore at an oil and gas wellsite. The apparatus may be a drilling fluid analysis system having a gas analyzer, a fluid analyzer, and a degasser operable to release and separate mud gas entrained in the drilling fluid. The degasser may include a gas-liquid separator having a separator inlet configured to receive the drilling fluid containing the entrained mud gas, a first separator outlet for discharging the mud gas fluidly connected with the gas analyzer, and a second separator outlet for discharging degassed drilling fluid fluidly connected with the fluid analyzer.

Abstract: A tool includes an internal assembly configured to be positioned at least partially within a body. The tool also includes a collet configured to be positioned at least partially within the body and axially-adjacent to the internal assembly. The collet includes a plurality of fingers that are circumferentially-offset from one another. At least one of the fingers includes a protrusion that extends adially-outward and is configured to be positioned at least partially within a recess formed in an inner surface of the body to secure the collet in place with respect to the body. The tool also includes a collet pin configured to be positioned at least partially within the body, axially-adjacent to the internal assembly, and at least partially within the collet. The collet pin is configured to contact the internal assembly to secure the internal assembly in place within the body.
