Abstract
The downhole portion of the system of the present invention provides entirely downhole methods and apparatus for the monitoring and control of wells. The components of the system are modular. There are sensor and control valve components located in each of the multi-zone production intervals or lateral well completions. The production zones are isolated by production packers equipped with feed-through conductors for communication to upper system components. There are a monitor and control module containing a programmable microprocessor controller and a power supply module which are located at the uppermost end of the system. The system provides for removing, decommissioning and/or replacement of the power module or the monitor and control module without decompleting the well. The surface portion of the system may be operated from the wellhead or by remote control. In a preferred embodiment, a surface-located test, question, or reprogram module is contained in a controlled buoyancy carrier mounted at the wellhead. The carrier is controlled by a surface control computer. The computer allows the controlled buoyancy carrier to 'fall' down through the production tubing and 'land' on the downhole monitor and control module. The carrier then interrogates the memory in the monitor and control module and/or reprograms its internal microprocessor as it has been instructed. The carrier then alters its own buoyancy to return via the production tubing to the surface. At the surface it reports the status or sends back the requested data it has gathered via the communications link to the operator.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
