Recovering More,
Emitting Less.™

Thermal technologies for enhancing
& decarbonizing heavy oil recovery.

GERI’s award-winning Direct Contact Steam Generation (DCSG) technology

provides a low emissions solution to unlocking proven undeveloped heavy oil reserves and boosting recovery rates in underperforming wells.

GERI’s portable DCSG co-injector injects steam (or produced hot water) and combustion exhaust gases (mainly N2 & CO2) into a well, simultaneously meeting the two fundamental needs of depleted heavy oil reservoirs: heat and pressure.

Compared to traditional enhanced oil recovery (EOR) steaming and heating technologies, GERI’s DCSG technology:

  • Significantly increases oil recovery rates
  • Significantly reduces greenhouse gas emissions
  • Fits within an existing standard well lease
  • Requires lower capital investment
  • Allows for quicker deployment

Applications for GERI’s DCSG technology include:

Heavy oil production in Alberta and Saskatchewan has notoriously poor recovery rates, often leaving as much as 90 per cent of the resource behind. It also tends to be emissions and capital intensive, meaning smaller deposits are not economically feasible to develop. A Calgary-based start-up has developed a technology that could entirely change that equation.
