Abstract: The present invention includes a method and system for automated choke control on a hydrocarbon producing well. The method includes sensing parameters such as sand production, well head tubing pressure, flow rate through the well system, and pressure differential between downhole tubing and an adjacent producing formation. The opening size of the choke is automatically changed, without need for human intervention, in response to changes in the sensed parameters to optimize operation of the well system. Ideally, a programmable logic controller is used to determine when the opening size on the choke should be changed. An advisory communication is preferably sent to a remotely located monitoring station advising that the opening size of the choke has been automatically adjusted. A decision is then made whether an operator should go to the well site and manually well test and shake out the well before placing the system on automatic operation again.

Abstract: A pilot for a gas fuel burner assembly is controlled so that the pilot is extinguished when the burner is ignited and lit when the burner is extinguished.
