Universal Citation: OR Admin Rules 632-020-0157

Current through Register Vol. 63, No. 12, December 1, 2024

(1) Injection wells must be constructed in compliance with the standards set in OAR 632-020-0095 and 632-020-0125.

(2) Special standards may be required by the department to allow for corrosive effects of injected fluids, precipitation of dissolved minerals, more extensive cementing of casings, specifications for tubing packers and casing packers, or other construction practices generally accepted by the industry.

(3) All wells for injection must be tested for mechanical integrity at least once every five years to determine that there is no leak in the casing and that there is no fluid movement into an underground source of water other than that from which the fluid was produced, unless otherwise approved by the department.

(4) Acceptable tests include pressure build-up profiles, pressure testing, and casing thickness logs to demonstrate integrity of the casing.

(5) The department may, on a case-by-case basis, approve tracer surveys, noise logs, temperature logs, spinner surveys, or other methods to detect water movement adjacent to the wellbore and seismic monitoring.

(6) The department must be notified two weeks before any mechanical integrity test. The results must be submitted within 60 days.
