20 AAC 25.287. Well control requirements for wireline operations

(a) This section applies to workover or service operations performed with slickline or conductor line with the tree in place. These operations are also subject to the requirements of 20 AAC 25.527.

(b) Well control equipment must include

(1) a set of wireline rams suitable or sized for each diameter of wire passing through the wireline valve;

(2) a lubricator or pressure deployment system; and

(3) a high pressure pack-off, stripper, or greasehead with linewiper, stripper, or pack-off.

(c) The rated working pressure of the well control equipment must exceed the maximum potential surface pressure to which it may be subjected. If an approved Application for Sundry Approvals (Form 10-403) is required under 20 AAC 25.280, the commission will specify in that approved application the working pressure that the equipment must be rated to meet or exceed. However, the rated working pressure of an annular type preventer need not exceed 5,000 psi.

(d) The operator shall test the well control equipment as follows:

(1) at least once a week, equipment must be function pressure-tested, using a non-compressible fluid, to the required working pressure specified in an approved Application for Sundry Approvals under 20 AAC 25.280 or, if that application is not required, to the maximum potential surface pressure to which that equipment may be subjected;

(2) after each installation of the well control equipment, that equipment must be pressure-tested, before wellbore entry, to the maximum potential wellhead pressure to which that equipment may be subjected;

(3) if the wireline valve rams have been used, repaired or changed, the wireline rams must be closed and function pressure-tested before wellbore entry, using a non-compressible fluid, to the required working pressure specified in an approved Application for Sundry Approvals under 20 AAC 25.280 or, if that application is not required, to the maximum potential surface pressure to which they may be subjected.

(e) The operator shall post in the operator's cab a copy of the approved Application for Sundry Approvals, if that application is required under 20 AAC 25.280, any geologic hazard information obtained while drilling the well, and a copy of the operator's standing orders specifying well control procedures.

(f) Upon request of the operator, the commission will, in its discretion, approve a variance from the requirements of this section if the variance provides at least an equally effective means of well control.
