The purpose of MMV is: 

• To determine if CO₂ migrates out of zone 
• To verify storage of CO₂ over geologic time 
• To ensure there is no impact on saline aquifers in the area

The potential for leaks is something that researchers, scientists and engineers take very seriously and are a key focus of CCS project planning to ensure leaks don't happen to begin with. Every conceivable scenario for stopping a leak and remediation of any damaged caused by a leak is taken into consideration as a part of CCS project planning.

• Since 2000, the Weyburn-Midale Project (WMP) has been monitoring and measuring CO₂ in the oil fields, to assure its permanent location and storage

• 3D Seismic arrays monitor the movement of CO₂ in the Weyburn‐Midale formation

• Wells are being monitored to assure integrity of seals

• Soil and potable well measurements are consistently being done
