The Advantages of HydroFlame

HydroFlame offers a technology solution to benefit businesses involved in Heavy Oil and Bitumen production. This solution offers environmental, technical, economical and global advantages:

  • Reduction in heat losses and increased efficiency.
  • Reduction in greenhouse gas emissions.
  • Production of heavy oil reserves from deep reservoirs and offshore.
  • Pressure maintenance in oil reservoirs due to flue gases injection resulting in longer production times.
  • Smaller footprint compared to surface steam generators.
  • Skid mounted units provide high mobility.
  • Direct heat transfer without any conduction materials between the hot combustion gases and water enables the use of lower quality water with minimal treatment.
  • Absence of metal-to-flame contact eliminates thermal gradients and degradation that can cause combustor failure and shutdown.
  • Design ensures long and trouble-free operation of the downhole steam generator in the reservoir environment.



The production of Heavy Oil and Bitumen necessitates the generation of huge amounts of steam to reduce the viscosity of the oil so that it can be produced to the surface. Steam generation requires burning fossil fuels, which sends three to five times more climate-changing greenhouse gases into the atmosphere than drilling for conventional oil. Surface steam generators produce 80 to 140 lbm of CO2 for every barrel of heavy oil produced at oil/steam ratios ranging from 0.3 to 0.5.

In contrast, in the HydroFlame steam generator, all the combustion gases are injected into the reservoir formation along with the steam, reducing the emission of greenhouse gases.


Major cost and energy savings occur due to reduced water treatment needs, reduced heat losses and increased efficiency.

Since the transfer of heat is direct in the HydroFlame steam generator without any walls between the hot combustion gases and the water, water of much lesser quality than that used in current streaming technologies can be used. This eliminates the need for expensive water treatment.

Heat losses from conventional steam generators can be greater than 20%. Such heat losses arise from stack gas losses, pipelines and the wellbore. With the surface steam generators, large insulated pipelines from the location of the steam generator to the well head are required to reduce pipeline heat losses. Building insulated pipelines adds to the capital cost of the whole operation. In contrast, heat losses from the the downhole steam generator are negligible. Even if the HydroFlame steam generator were operated on the surface, it could be operated right next to the wellhead, eliminating both pipeline losses and stack gas losses.
