The generic term "intelligent well" is used to signify that some degree of direct monitoring and/or remote control equipment is installed within the well completion. The definition of an intelligent well is a permanent system capable of collecting, transmitting, and analyzing wellbore production and reservoir and completion integrity data, and enabling remote action to better control reservoir, well, and production processes. The concept of the intelligent completion does not generally refer to any capability for automated self-control but relies upon manual interface to initiate instructions to the well. Remote completion monitoring is defined as the ability of a system to provide data, obtained in or near the wellbore, without requiring access and entry for conventional intervention to the well. Remote completion control implies that information and instructions can be transmitted into the well to alter the position or status of one or more completion components. The primary objectives of these abilities are normally to maximize or optimize production/recovery, minimize operating costs, and improve safety. As of 2002, there were some 80 intelligent-well completions with a variety of systems installed worldwide. Hydraulic motive power supplies predominate for these systems, although various hybrid electrohydraulic and optohydraulic completions have been successfully deployed.
