METHOD AND APPARATUS FOR THE REMOTE CONTROL AND MONITORING OF PRODUCTION WELLS

摘要

A system adapted for controlling and/or monitoring a plurality of production wells from a remote location is provided. This system is capable of controlling and/or monitoring: (1) a plurality of zones in a single production well; (2) a plurality of zones/wells in a single location (e.g. a single platform); or (3) a plurality of zones/wells located at a plurality of locations (e.g. multiple platforms). The multizone and/or multiwell control system of this invention is composed of multiple downhole electronically controlled electromecanical devices and multiple computer based surface systems operated from multiple locations. Important functions for these systems include the ability to predict the future flow profile of multiple wells and to monitor and control the fluid or gas flow from either the formation into the wellbore, or from the wellbore to the surface. The control system of this invention is also capable of receiving and transmitting data from multiple remote locations such as inside the borehole, to or from other platforms, or from a location away from any well site. The system further provides the possibility of communication between plural zones in a single well or between the zones in a single well or between the zones of different wells, the communication taking place between downhole telemetry devices.
