WebDownhole electric heaters are used to ignite the oil within the reservoir. As the internal reservoir burns the oil is extracted from the porous rock via the heat and steam generated from the combustion. Thermal management and monitoring of the downhole heater is essential to the ignition process. The SAGD process uses high pressure steam that ... WebSAGD (Steam Assisted Gravity Drainage) is a thermal recovery process for production of nearly immobile bitumen from the deeper oil-sand formation. In this method, two parallel horizontal wells are drilled near the reservoir bottom, one about 5 m higher than the other. Steam injected through the upper well provides heat to the heavy oil to reduce its viscosity.
