MCST Reduces Water Use and Green House Gas Emissions for SAGD
Air emissions and water usage are two of the major issues facing large steam generators found in SAGD (Steam Assisted Gravity Drainage) projects. Quadrise Canada’s goal is to develop fuels and technologies that have a neutral effect on the climate and either a neutral or positive effect on net water usage. MCST (MSAR Combustion and Sequestration Technology) has been developed to assist the oil and gas industry to accelerate natural gas and bitumen production from reservoirs and provide a zero emissions process that conserves water.
There are two types of water produced by burning MSAR, there is water that results from the combustion of the hydrocarbon and there is water that is part of MSAR when it is manufactured. During the MCST process, after MSAR is burned, the water can be recovered from the flue gases and can be recycled back into the SAGD process to eliminate the need for make up water. This is a great benefit to the industry which is facing an increasing need to reduce their water use.
MCST has also provided a solution to green house gas emissions. The MCST process compresses the flue gases after the water has been removed and injects the gas into the reservoir. This creates an essentially zero exhaust gas emissions process, alleviating the concern of polluting the atmosphere. Depending upon how the MSAR is burned, this process can also produce a high concentration CO2 gas that is effective in re-pressurizing reservoirs so that the natural gas can be removed from the reservoirs for sale. If you want to know more about this process, please see the section on What is MCST?.
