Water and other non-hazardous waste fluids produced in association with oil and gas or non-oil and gas activities in Saskatchewan can be disposed/injected into a subsurface formation through a disposal/injection well in accordance with Section 17.1 of The Oil and Gas Conservation Act and Section 53 of The Oil and Gas Conservation Regulations, 2012.
An operator can apply and receive authorization from the Ministry of Economy for a disposal well through the licensing or reclassification/recompletion process. Injection wells not related to disposal operations typically require an authorization to be generated before licensing; that authorization is usually related to reservoir applications (Enhanced Oil Recovery, waterflood, commingling, etc.).
Authorizations for a disposal/injection well are valid for one year from the approval date.
For more information refer to Directive PNG008: Disposal and Injection Well Requirements.
