  • Publication number: 20240174359
    Abstract: A rotorcraft includes a fuselage, a flight control computer, an auxiliary flight controller having one or more flight control inputs in the noncockpit section of the fuselage and a relay interposed between the flight control computer and the auxiliary flight controller such that the auxiliary flight controller is in data communication with the flight control computer via the relay. The relay prevents electromagnetic interference affecting the auxiliary flight controller from affecting the flight control computer.

  • Publication number: 20230074077
    Abstract: A method to facilitate the extraction of hydrocarbon from a coal seam gas formation is described that includes. : (a) drilling a wellbore using a drill string to access the coal seam gas formation; (b) perforating a section of the drill string; (c) abandoning a section of the drill string in the wellbore; (d) setting a temporary plug to isolate the abandoned section of the drill string and the wellbore; (e) installing a production tubing string above the temporary plug to create a fluid passageway ; (f) displacing a fluid above the temporary plug ; (g) removing the temporary plug to create an initial stimulated reservoir volume and, resultantly, at least partially filling an annulus formed between the abandoned section of the drill string and the wellbore wall with coal fragments; and (h) extracting hydrocarbon from the coal seam gas formation via the fluid passageway to create an expanding stimulated reservoir volume.

  • Patent number: 8714004
    Abstract: A method of measuring the in-situ Total Gas content of an unconventional reservoir rock, the method including: drilling a borehole through a measurement interval in the reservoir to generate an annular volume of drilling mud that includes cuttings and gas, the annular volume having a leading edge and a trailing edge; diverting the leading edge of the annular volume such that all of the annular volume is captured in a degassing storage system without being exposed to atmosphere; discontinuing the diversion of the annular volume when the trailing edge of the annular volume has been captured in the degassing storage system; measuring the gas volume in the degassing storage system to determine the amount of gas per annular volume; and calculating the in-situ Total Gas content of the reservoir with reference to the amount of gas and cuttings per annular volume.

  • Publication number: 20070175373
    Abstract: A vessel (2) comprises a first stabilizer assembly (14) and a second stabilizer assembly, each stabilizer assembly comprising at least one submergible at least partially hollow body; and suspending means (16) for suspending the or each body from the vessel, the first and second stabilizer assemblies being suspended from substantially opposite sides of the vessel. Fins (22) are provided on the stabilizer assembly.
