Downhole Heating & Steam-Assisted Gravity Drainage Applications
Other forms or EOR are downhole heating and SAGD. These proven methods provide a means of artificial lift to existing oil and bitumen reservoirs.
Downhole 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 is continuously injected into the upper wellbore to heat the oil and reduce its viscosity, causing the heated oil to drain into the lower wellbore, where it is pumped out. Chromalox low voltage and Medium Voltage DirectConnect Steam Generators are an excellent zero emission solution for SAGD applications. Electric Steam superheaters can also be used to improve steam quality on long steam lines.
The Oil and Gas Exploration and Production industry demands robust, technological advanced, regulatory compliant, safe, and reliable electric heater and thermal management products. Chromalox continues to be a trusted partner during the initial design process throughout the facility’s life cycle.
Drilling Mud Piping Distribution
Self-regulating and constant-wattage heat trace cables are used for pipe temperature maintenance and freeze protection.
Drilling Mud Storage Tanks
Heaters are used to maintain or improve the viscosity or density of recirculating fluids for improved drilling efficiencies.
Waxy Crude Heaters
Circulation heaters warm the crude oil to improve viscosities for more efficient pumping and distribution.
Submersible electric heaters warm viscous oils for easy extraction from the well.
Blower, convection, and radiant heaters provide comfortable temperatures inside operation buildings.
Steam Piping Network
Mineral-insulated heat trace cable is used for temperature maintenance in high-temperature steam piping.
Steam-Assisted Gravity Drainage
Precision control of the steam quality used in horizontal wells can be accomplished with circulation heaters and SCR power control during extraction of heavy crude oil and bitumen.
Skin-effect pipe heating, above- or below-ground, keeps oil warm for long distance transmission.
