ASSIST’s direct contact steam generation and reservoir heating process offers competitive advantages over conventional steam generation technologies as follow:
- Higher energy efficiency: hot combustion gases are conserved and used to both heat and pressurize reservoirs, with the added benefit of providing blanket gases that reduce heat loss to the overburden. The SCV process also produces and conserves CO2 which has the effect of reducing oil viscosity and increasing oil production.
- Ability to use non-thermal heavy oil wells in thermal service due to use of a patent pending well recompletion and operation method which incorporates production and injection of a well annulus cooling fluid.
- Ability to utilize raw untreated produced water for steam generation. The competitive OTSG requires that companies invest in expensive water treatment facilities to produce boiler feed water.
