Publication number: 20070254795Abstract: A conical housing of a horizontal decanter centrifuge includes a discharge port liner that attaches to the conical housing from the outside of the housing. The discharge port is substantially rectangular in configuration, and the liner slides down into the port opening. The liner is coupled to the housing with bolts or similar releasable coupling means.Type: ApplicationFiled: April 26, 2006Publication date: November 1, 2007Applicant: Hutchison Hayes L.P.Inventors: Gary Hensley, Lee Hilpert

Patent number: 7255670Abstract: A three-phase decanting centrifuge is provided. Solids are removed from a slurry in the centrifuge in the conventional manner, as described above. The liquid separated from the slurry moves into a fluids reservoir. Centrifugal action classifies the fluids, with lighter fluids (typically oil) radially closer to the axis of rotation of the machine, while the heavier fluids are radially farther from the axis, i.e. at the bottom of the reservoir. Lighter fluids flow out a plurality of overflow tubes. Heavier fluids flow through a plurality of ports into a heavy fluids reservoir to be skimmed out by a pair of radially actuatable skimmer tubes. The skimmer tubes are preferably automatically operated based on the light transmissivity of the lighter and heavier fluids discharged from the machine.Type: GrantFiled: February 25, 2005Date of Patent: August 14, 2007Assignee: Hutchison Hayes, L.P.Inventors: Gary Hensley, Lee Hilpert

Patent number: 7001324Abstract: A method of retrofitting a centrifuge is provided. The method includes disassembling a known centrifuge and replacing a bowl section of the centrifuge outer body with a longer bowl section. The method further comprises replacing the conical beach section with a shorter beach section, i.e. a beach section having a greater slope. The screw conveyor is replaced with another screw conveyor having outlet nozzles adapted to impart rotational movement to the inlet feed. The retrofitted centrifuge provides enhanced performance through an additional length of cylindrical section, thereby making the clarification length longer, and improving the effectiveness of the centrifuge in removing solids from the inlet feed. The retrofitted centrifuge preferably remains mounted to the same pedestal as the centrifuge prior to retrofit.Type: GrantFiled: January 5, 2004Date of Patent: February 21, 2006Assignee: Hutchison Hayes, L.

Publication number: 20050183994Abstract: An integrated, transportable cuttings treatment system includes a multi-part shale shaker, preferably formed of six screens vibrated by at least one electric vibrator, and preferably four such vibrators. Solids are screen from drilling mud flowing onto the screens, and directed into a trough wherein is located a screw conveyor or augur. A pressure differential is developed across the screens to increase the flow rate of drilling mud through the screens.Type: ApplicationFiled: February 4, 2005Publication date: August 25, 2005Applicant: HUTCHISON HAYES, L.P.Inventors: Gary Hensley, Lee Hilpert

Patent number: 6823721Abstract: A system which receives as inputs various measurements of solids and liquids in a clarification system and, from these measurements, determines the various constituents and their fractional makeup within the system. The measurements may be made manually or mechanically, but are preferably made manually. From a quantitative analysis of easily accessible sample points, data is acquired and plugged into a spread sheet program, which numerically and graphically displays the breakdown of the constituents which make up the solids and liquids discharged from a treatment stage or of the entire system.Type: GrantFiled: December 11, 2002Date of Patent: November 30, 2004Assignee: Hutchison Hayes, L.P.Inventors: Lee Hilpert, Gary L. Hensley

Patent number: 6823238Abstract: A method and apparatus selective remove undesirable low gravity components from the return stream of drilling mud. The apparatus receives mud returned from the well borehole and transfers the mud to a tank. Mud from the tank is treated in a separation system including a plurality of mass flow sensor to monitor operation of the system.Type: GrantFiled: May 26, 2000Date of Patent: November 23, 2004Assignee: Hutchison Hayes L.P.Inventors: Gary L.
