Abstract
A gas and oil well controller includes a microcomputer control circuit which can control well production by monitoring well pressure levels, by time limitations, or any combination of the two. The controller includes a casing pressure sensor, a tubing pressure sensor for sensing casing/tubing differential pressure and tubing/line differential (flow) pressure, a line pressure sensor for sensing pressure in the sales line, and a plunger position sensor for sensing the position of a plunger adjacent a top position in the well tubing. The microcomputer control circuit is in operative communication with the production valve, the casing pressure sensor, the tubing pressure sensor, the line pressure sensor, and the plunger to open and close the production valve for gas flow to the sales line when the casing, tubing, and line pressures bear a predetermined relationship to preselected pressure limits or when the plunger is sensed by the plunger sensor. The controller includes serial and parallel communication ports through which all communications to and from the controller pass. Any hand held device or portable computer capable of serial communication may access the controller. A telephone modem or telemetry link to a central 'host' computer may be used to permit several controllers to be accessed remotely. Security and individual controller selection is provided by a specfic password code to prevent unauthorized access to the controller.

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.
