A downhole valve is described. The downhole valve has a pilot valve section and a tool section. The pilot valve section has a first tube. The tool section has a second tube slidably coupled to the first tube of the pilot valve section so as to provide fluid communication between the pilot valve section and the tool section. The tool section can be in the form of a signal valve section of a mud pulse telemetry valve, a reamer, a vertical steerable tool, a rotary steerable tool, a by-pass valve, a packer, a whipstock, or stabilizer.

Systems and methods of the present disclosure relate to protecting a control line as it passes through a junction in a downhole environment. A retractable transition joint (RTJ) comprises at least two members. A first member is operable to retract into a second member. A tubular extends through the first and second members. The tubular comprises a distal end that is removably attached to a distal end of the second member. The first and second members are operable to receive the control line.

An apparatus and method of use for dampening shock and vibration imparted on a unified (e.g., single) and/or dual telemetry measurement-while-drilling (MWD) assembly by a drilling system during the drilling of a wellbore in a subterranean formation is provided. The apparatus may be configured to be threadably engaged and housed within the drilling system, wherein the apparatus reciprocates axially with the MWD assembly, dampening axial and torsional shock and vibration imparted on the assembly, while maintain mud-pulse and electromagnetic signals transmitted by the assembly.

A vibration-damping sub is provided to mitigate shock and other sources of vibration in a tool string. In examples, a tubular damping body is rigidly coupled between a vibration-sensitive tool and a vibration source. The tubular damping body includes a tubular wall defining a plurality of shaped holes configured to dampen the mechanical vibration to below the design threshold for the vibration-sensitive tool. The tubular damping body may also include different portions having different materials and impedances to further disrupt the propagation of mechanical waveforms.

A body defines a feedthrough passage. Bow springs surround and connect to an outer periphery of the body. The bow springs extend radially outward from the body. An internal coil spring is arranged to actuate axially within the body. A mandrel abuts an end of the coiled spring. The mandrel is arranged to move within the body, the mandrel having sufficient inertia to dampen vibrations.

A vibration isolating coupler including a first coupler portion, a second coupler portion including an external surface and an internal surface portion, and a vibration isolating portion extending between the first coupler portion and the second coupler portion. The vibration isolating portion including a first solid annular portion and a second solid annular portion. The vibration isolating portion including a plurality of slots extending from the first solid annular portion toward the second solid annular portion forming a plurality of vibration isolating elements. Each of the plurality of vibration isolating elements is disconnected from adjacent ones of the plurality of vibration isolating elements by a corresponding one of the plurality of slots. The plurality of vibration isolating elements enabling torsional rotation of the first coupler portion relative to the second coupler portion.

A utility umbilical module may include an expandable frame, a plurality of extendable fluid lines arranged on the expandable frame and configured for fluid coupling between a utility plant and a drill rig, an expandable and retractable electrical system configured for electrically coupling a utility plant to a drill rig, and a ground engaging portion configured for over-the-road transport of the module.
