Common Question
Does solution gas stimulation require Directive 065 approval?
Archive Findings
AER advised that D065 approval was not needed for the specific 2019 proposal because it was one-time well stimulation using sweet solution gas, limited to 7 days and 28 e3m3/d, and was not EOR or emergency temporary gas injection.
If the purpose, gas, rate, duration, repeat use, or EOR connection changes, the conclusion can change.

Document purpose, gas composition, rate, duration, wells/events, and why the activity is not EOR or temporary injection. Re-check approvals if any fact changes.
Current Guidance
Use Directive 065 for reservoir approvals. Check Directive 056/Manual 012 for equipment or facility changes and Directive 060 for flaring, venting, or incineration.
