Abstract: A device for cold rolling a thread on a tubular support member of a rotary shouldered thread connection includes obtaining an original root depth of a thread root, cold rolling the thread until a minimum increased root depth tolerance is achieved.

Abstract: A technique facilitates controlling fluid flow in a well system or other flow related system. The control of fluid flow may be accomplished by utilizing a flow control valve which is selectively actuated via the controlled application of an actuating fluid. An isolation valve is positioned along the flow of actuating fluid at a location upstream of the flow control valve. The isolation valve establishes a preset pressure which is applied to establish flow of actuating fluid to the flow control valve and also isolates detrimental pressure transients. For example, the isolation valve may be used to reduce or block the propagation of detrimental pressure transients along the actuating fluid to other controlled devices.

Abstract: An electric submersible pump device having a motor part, a pump part, and a protector part. The protector part includes redundant shaft seal parts.

Abstract: An assembly employing multiple eccentric devices about a mandrel. The assembly is configured such that at least one of the eccentric devices is adjustably orientable relative another. Thus, for example, where the devices are packers disposed about completions tubing, the adjustable orientation may be utilized to ensure enough clearance is available for downhole advancement of the assembly. As such, the assembly may remain eccentric in nature without concern over damage during positioning, particularly to a communication line running to actuatable implements of equipment coupled to the completions assembly.

Abstract: A technique is provided that utilizes one or both of a control line actuation mechanism and a connector protection mechanism for use in a wellbore environment. Upon landing a lower well assembly and an upper well assembly at a desired wellbore location, control line connectors are engaged. The control line actuation mechanism and/or connector protection mechanism facilitate the formation of a desirable control line connection.

Abstract: A completions system utilizing a unique hydraulic coupling. The system includes an upper completion stinger configured for coupling to a lower completion tubular. Both the stinger and the tubular are outfitted with hydraulic lines therethrough. Thus, as the stinger is coupled to the tubular, hydraulic lines are also coupled. However, the termination of each line is sealingly covered by a slidable sleeve in advance of attaining the coupling between the stinger and tubular. Therefore, the lines are protected from contamination during potentially significant periods of well deployment that may occur in advance of completed coupling and system installation. Furthermore, the manner of hydraulic coupling between the stinger and tubular reduces the likelihood of damage to the hydraulic lines during the installation process.
