REAL-TIME PRODUCTION-SIDE MONITORING AND CONTROL FOR HEAT ASSISTED FLUID RECOVERY APPLICATIONS
An automatic control system that protects downhole equipment and surface equipment from high temperatures resulting from the breakthrough of injection vapor. The system operates to derive an estimate of the temperatur e of production fluid at a location upstream from the downhole equipment. An alar...

| description | An automatic control system that protects downhole equipment and surface equipment from high temperatures resulting from the breakthrough of injection vapor. The system operates to derive an estimate of the temperatur e of production fluid at a location upstream from the downhole equipment. An alar m signal is generated in the event that this temperature exceeds a threshold temperature characteristic of injection vapor breakthrough. Electric power t o the downhole equipment is automatically shut off in response to receiving the alarm signal. A bypass valve selectively directs production fluid to a bypass path . The system operates to derive an estimate of the temperature of the production fluid at a location upstream from the surface equipment. An alarm signal is generated when this temperature exceeds a threshold temperature characteristic of injection vapor breakthrough. The bypass valve is automatically controlled t o direct production fluid to the bypass path in response to receiving the alar m signal. |
