Patent number: 10160913Abstract: This invention relates to the separation of shale, gas and fluid at a shale-gas well. The shale debris and water from a shale-gas well is tangentially communicated to a vessel where the cyclonic effect within the vessel facilitates the separation of the gas from the shale debris. The separated shale debris and fluid falls to a jet assembly whereby it encounters a jet communicating a fluid therethrough. A venturi provides a motive force to the shale debris and fluid sufficient to propel it into a collection bin. The shale-gas separator incorporates a fluid bypass overflow line to prevent a buildup of fluid within the vessel. The shale-gas separator also incorporates an internal aerated cushion system (IACS) pipe for further motivating the shale debris and into the jet assembly, to ensure the walls of the vessel are clean, and to provide an air cushion restricting gas migration to the jet assembly.Type: GrantFiled: June 20, 2014Date of Patent: December 25, 2018Assignee: MATHENA, INC.Inventor: Harold Dean Mathena

Patent number: 9353586Abstract: According to one aspect, a digital display unit includes a microcontroller to process digital information received from one or more sensors, a display, and a switch in electrical communication with the microcontroller so that the microcontroller displays an output on the display that is specific to a type of sensor. The type of sensor may be selected from a position sensor, a pressure sensor, and a stroke counter. The digital display unit may be part of a choke control panel. The microcontroller and the display may be disposed in an enclosure, and an electrical power source may be disposed in the enclosure to supply electrical power to the microcontroller and the one or more sensors. A digital hydraulic choke position sensor assembly and a digital pressure sensor assembly are also described, one or both of which may be used in a system for drilling an oil or gas well.Type: GrantFiled: May 10, 2013Date of Patent: May 31, 2016Assignee: MATHENA, INC.Inventors: John Mathena, Bill Bennett

Publication number: 20140131030Abstract: This invention relates to an ecologically and environmentally friendly mud-gas containment system. Specifically, this invention relates to a mobile device that is capable of receiving waste gas and, in emergency situations, a volume of a mud-gas mixture from a drilling operation. The waste gas is communicated to a removable flare stack through a vent line. The mud-gas is received at a containment vessel. The impact of the mud-gas within the containment vessel separates the mud-gas into mud and waste gas. The mud is collected for recycling and/or environmentally sensitive disposal. The waste gas from the vessel is communicated to the flare stack. Separate removal ports and conduits are used to remove any residual mud or mud-gas from the vent line and/or containment vessel. Excess mud or mud-gas is communicated to an overflow catch tank for removal. The entire assembly is mounted on a mobile skid sized for highway transportation.Type: ApplicationFiled: January 17, 2014Publication date: May 15, 2014Applicant: Mathena, Inc.Inventor: Harold Dean Mathena
