  • Publication number: 20230119473
    Abstract: A fluid conduit assembly for a fluid supply system includes a low-pressure conduit assembly. The low-pressure conduit assembly includes a low-pressure conduit, multiple low-pressure inlets, and multiple low-pressure outlets. Each low-pressure inlet includes a fluid passage configured to independently direct low-pressure fluid from a fluid source to the low-pressure conduit, and the low-pressure outlets are configured to direct the low-pressure fluid from the low-pressure conduit to multiple fluid pumps.

  • Publication number: 20230100479
    Abstract: A fluid conduit assembly for a fluid supply system includes a low-pressure monobore conduit assembly having a low-pressure monobore conduit and low-pressure outlets. The low-pressure outlets are configured to direct low-pressure fluid from the low-pressure monobore conduit to pumps. At least one first low-pressure outlet is positioned on a first side of the low-pressure monobore conduit, and at least one second low-pressure outlet is positioned on a second side of the low-pressure monobore conduit. The fluid conduit assembly includes a high-pressure monobore conduit assembly having a high-pressure monobore conduit and high-pressure inlets. The high-pressure inlets are configured to direct high-pressure fluid from the pumps to the high-pressure monobore conduit. At least one first high-pressure inlet is positioned on a first side of the high-pressure monobore conduit, and at least one second high-pressure inlet is positioned on a second side of the high-pressure monobore conduit.

  • Patent number: 8561726
    Abstract: Systems and methods for controlling deviations during drilling operations include securing a plurality of stabilizers to a lower portion of a drill string. The stabilizers can have a substantially triangular cross-sectional area oriented perpendicular to the longitudinal axis of the drill string, and a plurality of blades secured to the stabilizer at points associated with corners of the triangular cross-sectional area. The resulting system can exhibit improved stability and stiffness, an improved flow area, a reduced annular velocity, an increased penetration rate, and a longer usable life.

  • Patent number: 8061451
    Abstract: Systems for controlling deviations during drilling operations, including a transmission housing and a bearing assembly secured between a stator housing and a drill bit. Two stabilizers are secured to the transmission housing, and one stabilizer is secured to the bearing assembly to provide enhanced stability to the lower portion of the drill string. The stabilizers can have a triangular shaped body for increasing flow area, reducing annular velocity, and increasing stiffness of the system. The stabilizers can be rotationally offset from one another to facilitate maintaining the gauge of the borehole. The transmission housing can be a one-piece construction to minimize connections within the system and improve reliability. The stabilizers can include laser clad metal surfaces and diamond dome inserts to prevent wear and erosion. A triangular reamer can be included beneath the stabilizers to further prevent wear to the stabilizers and to add stability to the drill bit.
