Abstract
A self-regulating lift fluid injection tool (,) adapted for placement within production tubing (,). The tool (,) has a control valve (,) that controls the rate of injection of a lift fluid (,) into the formation fluids (,) being produced through the production tubing (,). A sensor (,) monitors the flow rate of the formation fluids (,) through the production tubing (,). The sensor (,) generates a signal indicative the flow rate of the formation fluids (,) which is sent to an electronics package (,). The electronics package (,) generates a control signal in response to the signal received from the sensor (,) that is received by an actuator (,). The actuator (,) adjusts the position of the control valve (,) to regulate the flow rate of the lift fluid (,) therethrough in response to the control signal, thereby optimizing the flow rate of the formation fluids (,).
