Definition - What does Electromagnetic Heating mean?
Electromagnetic Heating is a process used to increase the thermal energy in a reservoir by using electromagnetic sources. There are two types of Electromagnetic Heating, i.e., radio frequency and conductive heating. In radio frequency heating, the transmitters in a borehole give rise to electromagnetic waves having frequencies in microwave range which are directed into the formation. These waves interact with water molecules and generate heat in the same way a microwave does. In the conductive heating, a current is passed from one electrode to another through the formation.
Petropedia explains Electromagnetic Heating
Electromagnetic Heating of reservoirs and oil wells is a thermal process used to improve oil production from underground reservoirs. Sources of heat which are generated in the reservoirs or the wells are the electrical energies that are supplied from the surface. The energies are then transmitted to reservoirs through metal structures or by cables which reach the reservoir. The major effect of the process is the reduction of viscosity of the heavy and extra heavy bitumen and crude along with the corresponding increase in the production. In Electromagnetic Heating, the production is never interrupted by the use of electrical power.
