Protection of production well equipment in in situ combustion operation
Patent
·
OSTI ID:6369197
A jacketed tubing shoe is used to prevent overheating and destruction of downhole equipment in a production well in an in-situ combustion operation. The shoe is positioned on the lower end of the tubing string adjacent to the oil stratum and fluid coolant (water) is injected into the shoe and vented from its lower end into the produced hot fluids. A temperature-sensing means, positioned adjacent to the stratum or the tubing shoe, communicates with a recorder and controller at ground level to operate control means in the fluid coolant line in response to sensed temperature.
