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.

Downhole wet mate connection

An apparatus and method for plugging a wellbore completion. The apparatus includes a body and a variable diameter ring. The body includes a first portion having a first diameter, and a second portion having a second diameter that is smaller than the first diameter. The variable diameter ring is disposed around the body and slidable on the first and second portions. The ring is configured to engage a flow path reduction device when located on the first portion, and to move past the flow path reduction device when located on the second portion.

Deformable dart and method

According to one or more aspects of the present disclosure, a piezoelectric pump may include a hydraulic fluid path between a low pressure source and a high pressure tool port; a fluid disposed in the hydraulic fluid path; a piston in communication with the fluid; and a piezoelectric material connected to the piston to pump the fluid through the high pressure tool port.

Downhole piezoelectric devices

An apparatus includes a connector to connect a first tubing section and a second tubing section together. The connector that includes a body that includes a first opening to receive the first tubing section, a second opening to receive the second tubing section, and a passageway. The apparatus includes a member that is adapted to be moved from a retracted position to an extended position to form a sealed connection between a tubular member that is connected to the first tubing section and the passageway.

Joining tubular members

A technique is provided to facilitate connection of completion assemblies at a downhole location. A completion assembly comprises a control line conduit having a connector designed for coupling with a corresponding connector of a next adjacent completion assembly. A cover is selectively used to block entry of debris and other contaminants into the connector during deployment of the completion assembly downhole prior to engagement with the next adjacent completion of assembly.

System and method for forming downhole connections

A technique that is usable with a subterranean well includes communicating a slurry through a shunt flow path and operating a control device to isolate slurry from being communicated to an ancillary flow path. The system may include a shunt tube and a diverter. The shunt tube is adapted to communicate a slurry flow within the well to form a gravel pack. The diverter is located in a passageway of the shunt tube to divert at least part of the flow. A slurry may be communicated through the shunt flow path, and a control device may be operated to isolate the slurry from being communicated to the ancillary flow path.

Gravel packing a well

The present invention provides for a design and method of manufacture for a mesh-type screen to be used in subsurface well completions to prevent the production of sand.

Mesh screen apparatus and method of manufacture

A completion assembly for use in a lateral well bore has a base pipe with a plurality of holes through the sidewall of the base pipe. Flow through the holes is regulated to produce an influx difference between the ends of the base pipe. Flow can be regulated by variably spacing or sizing the holes. Flow can also be regulated by selectively inserting a rod between adjacent splines located on the base pipe to cover and block the flow through certain holes in the base pipe. Flow can also be regulated using a rotatable sleeve adjacent to the base pipe such that rotation of the sleeve brings the holes and openings in the pipe and sleeve, respectively, into and out of alignment. A filter can be used to filter sand and other particulates. An erosion inhibitor can be used to extend the useful life of the assembly.
