IT APPEARING THAT:

1. Unocal Company (Unocal) requested on January 20, 1987 the Alaska Oil and Gas Conservation Commission to authorize the use of well KU 14-4 as a disposal well in the Kenai Unit, Kenai Gas Field. Unocal will inject non-hazardous waste fluids generated by normal drilling and production operations.

2. Notice of an opportunity for a public hearing on March 11, 1987 was published in the Anchorage Daily News on January 30, 1987.

3. No protest or request for a public hearing was timely filed. Accordingly, the Commission will, in its discretion, issue an order without a public hearing.

FINDINGS:

1. All aquifers below 1300 feet within the Kenai Gas Field Boundary, and one-quarter (1/4) mile beyond, are exempted under 40 CFR 147.102 (b) (l) (C) for Class 11 injection activities.

2. Permeable strata, that will accept injected fluids, are present below 2900 feet in well KU 14-4.

3. A series of confining strata are present above 2900 feet in well KU 14-4 that will prevent upward movement of the injected waste fluids into non-exempt aquifers.

4. The strata into which fluids are to be injected will accept fluids at injection pressures which are less than the fracture pressure of the injection strata and their confining formations.

5. To ensure that waste fluids are confined to injection strata, the mechanical integrity of KU 14-4 will be demonstrated periodically and monitored routinely for disclosure of possible abnormalities in operating conditions.

6. KU 14-4 is constructed in conformance with the requirements of 20 AAC 25.412.

CONCLUSIONS:

The geologic sequence present at the well site and maintenance of the mechanical integrity of KU 14-4 will prevent movement of Injected fluids into non-exempt aquifers,

NOW, THEREFORE, IT IS ORDERED THAT:

Non-hazardous oil field waste fluids may be injected in conformance with Alaska Administrative Code Title 20, Chapter 25, for the purpose of disposal into the Sterling formation below the measured depth of 2900 feet in well KU 14-4.

DONE at Anchorage, Alaska, and dated February 18, 1987.
