Surface equipment protection from borehole pulsation energies
A pulsation and acoustic energy reduction dampener for installation within well piping between a standpipe and a swivel includes a body formed from a union connection sub providing a threaded male connection at one end of the body and welded to a union connection nut providing a threaded female connection at the other end, each for connection to the well piping. A flow restriction orifice assembly is secured by welding or gluing within the union connection sub and includes a replaceable wear component such as an annular ceramic insert with a tapered or cylindrical interior through-hole.

Crowding avoidance apparatus and method
A crash avoidance system or crowding avoidance sub (CAS) may be a dedicated or adapted subassembly (sub) in a bottom hole assembly (BHA), such as somewhere above the motor and bit, or between a drill string and BHA. With data lines in a modified housing and flex lines for relative, linear, axial motion between movable parts of a single sub, sensors are contemplated to put a CAS ahead of a cushion, jar, or shock sub, even a motor. However, sensors are best connected to an Intellisys™ data connection system providing a data stream to a computer on the surface. Certain preprocessing may be done down hole, but need not be. Control of the drive system of the hook feed rate is directly controlled in real time by a data station receiving, and operating based on, certain information received from the down hole sensors of the CAS.
System and methodology using locking sealing mechanism
A technique facilitates deployment and operation of a pumping system, e.g. an electric submersible pumping system, in a borehole. A locking and sealing mechanism, e.g. a spring-loaded locking sealing mechanism, may be coupled with the pumping system and comprises an anchoring section along with a sealing section. The locking sealing mechanism may be constructed for deployment with the pumping system via a running tool. Once in position downhole, the anchoring section and the sealing section may be actuated into sealing engagement with the interior surface of a surrounding tubing. At this stage, production of a desired fluid may be accomplished by operating the pumping system.
DOWNHOLE VALVE SPANNING A TOOL JOINT AND METHODS OF MAKING AND USING SAME
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.

Dual clutch system for travel joint
A dual clutch travel joint system includes an inner-mandrel and an outer-mandrel. The inner-mandrel includes a first connector on a downhole portion of the inner-mandrel and a second connector on an uphole portion of the inner-mandrel. The outer-mandrel includes a third connector that is positionable to mate with the first connector to apply torque to the inner-mandrel while the inner-mandrel is in a tension arrangement with the outer-mandrel within a wellbore. Additionally, the outer-mandrel includes a fourth connector positionable to mate with the second connector to apply torque to the inner-mandrel while the inner-mandrel is in a compression arrangement with the outer-mandrel within the wellbore.

Bi-directional downhole valve
The present disclosure provides a valve assembly comprising a valve section, a power section, and an electronics section. The valve assembly is configured to mate with a tubing sub (and/or mandrel) inserted in-line with a tubing string inserted into a wellbore. The valve allows for injection into or production from the tubing string. The valve assembly comprises an electric motor and a motor controller permitting fine control over the valve, as well as sensors which measure various parameters, such as fluid flow, valve position, pressure, temperature, and/or water cut. A cable connects the valve assembly to the surface and provides power and data telemetry and allows control of the valve assembly with a remote electronic signal. Multiple valve assemblies may be provided at spaced intervals along the tubing string and individually monitored and/or controlled by a remote location. Also disclosed is a method for operation of such valve assemblies.
Telescoping Transition Joint For The Protection Of Control Lines And Other Tools And Components
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.
