An operator must apply to and receive authorization from Saskatchewan's Ministry of Energy and Resources through the Integrated Resource Information System (IRIS), before licensing, recompleting or reclassifying a well associated with a specific storage project, as outlined in Section 17 of The Oil and Gas Conservation Act.
There are three application types in IRIS related to storage operations:
- Storage Project
A storage project means a development for the storage of hydrocarbon in underground reservoirs and salt caverns, and the disposal of wastes in salt caverns.
- Geothermal Project
A geothermal project means a development that geothermal fluids are produced from a water source well, the geothermal energy is recovered at surface as part of an industrial process for any purpose, and the cooling fluids are disposed into subsurface through a waste disposal well.
- CO2 Storage Project
A CO2 storage project means a development that is the long-term isolation of CO2 in subsurface geological formations, and is primarily applicable to saline aquifers and depleted hydrocarbon reservoirs. It does NOT preclude to storage associated with hydrocarbon recovery - CO2 Enhanced Oil Recovery (EOR), and does NOT include CO2 storage in unminable coal beds, basalt formations, shales, and salt caverns, and disposal of acid gas.
