Fluid Recovery System: samples from more than 3 km underground
Monday, Apr. 13, 2015

Aquistore is Saskatchewan’s leading industrial laboratory. Home to the Canada’s first deep saline CO2 storage project, Aquistore is also the world’s first CO2 storage site associated with an industrial scale (active and working) coal-fired power plant. PTRC manages the research and monitoring associated with the storage of CO2 3.4 kilometers underground. Aquistore has over $15M in monitoring equipment dedicated to observing and monitoring the movement of CO2 in the subsurface, and tracking groundwater and soil gas to ensure injected CO2 is contained in the storage reservoir.

In addition to the important and required monitoring equipment, Aquistore is home to some innovative installations. Scientists and organizations from around the world are taking advantage of the Aquistore site to test and develop groundbreaking technologies to help industries including and beyond CCS. One such technique is a made-in-Canada Fluid Recovery System (FRS). Developed by the University of Alberta this patent-pending system can take continuous samples of reservoir fluid from 3200 metres below the surface can be sampled, preserved, and brought to surface in ‘in-situ’ conditions. What makes the FRS unique is that it is installed on the outside of the casing and does not interfere with other critical monitoring technologies being deployed in the observation well.   Typically, fluid samples can be contaminated by other materials such as drilling fluid or the air on surface. The samples from the Fluid Recovery System at Aquistore will be preserved in the same state and condition they are found in. 

This one of a kind system will help scientists gain valuable insight into the conditions of the reservoir which will help broaden the scientific knowledge of our earth’s geology and underground environment (geomechanics and geochemistry). The in-situ samples will help illuminate what our subsurface is like – over 3 km below our feet.
