GERI has developed and tested a Direct Contact Steam Generator (DCSG) that is capable of injecting 80% steam quality with combustion flue gases at pressures up to 7 MPa, with rates between 5.5-11 GJ/hr (5-10 MMBTU/hr). We can inject into Steam Assisted Gravity Drainage (SAGD) wells for pre-heating during facility construction, late-stage SAGD repressurization, and also into older Cold Heavy Oil Produced with Sand (CHOPS) wells. Our system is highly portable and requires only a supply of natural gas, and boiler grade water – we produce the steam, nitrogen and carbon dioxide to heat and pro

GERI's Annular Cooling Loop* provides the ability to steam non-thermally cased and cemented wellbores. Our testing of pilot projects around the Lloydminster area has shown a maximum annular temperature of 60°C during steaming operations. The system operates as a closed loop with the ability to add additional makeup water if required. It also meets regulatory approvals granted for use in non-thermal wells both in Alberta and Saskatchewan.
General Energy Recovery Inc (GERI) is a service company focused on providing our clients with steam and flue gases for enhanced heavy oil production. GERI has researched and developed a high-pressure direct contact steam generator technology in the Lloydminster area of Alberta. Our commercial process produces less emissions and uses less water than traditional steam injection facilities used in CSS or SAGD operations.
We are a privately funded technology company with operations based out of Lloydminster and with head office located in downtown Calgary.
