Control Line/Cable

Definition(s)

Control Line/Cable

The control line/cable category allows information to be stored for control lines and cables and a variety of parts that are normally associated with control lines or cables. Examples of such parts are packer penetrators, electric connectors for gauges, electric wellhead connectors, etc. This category provides the opportunity to build control line/cable “systems” consisting of the hydraulic control line or cable itself and all associated parts.

Definition(s)

Accessories

Accessories are items that are required to be tied to a “host” string item to define a system. This is done to be able to logically represent string items which are too complex to be given as just a stand-alone item of the string. Only two such “host” string items, or string items with accessories, have been defined to date. These are the electrical submersible pump (ESP) and downhole permanent gauge (DHPG) systems.
