Mich. Admin. Code R. 408.15744 - Lubricator operations
Rule 5744.
(1)
The provisions of this subrule apply when downhole tools are being run on a
wire line in a well and a lubricator is used to allow removal of the tools
under pressure.
(2) A lubricator,
including the swages and unions, shall be visually inspected for defects before
use. Any defects that may affect safe operations shall be corrected before
installation.
(3) All valves and
gauges shall be checked to be certain that there is no pressure on the
lubricator before working on or removing it.
(4) When a lubricator is installed on a
wellhead, an outlet below the lubricator shall be provided for well control
operations.
(5) When downhole tools
are being run on a wire line in wells where surface pressure is suspected, a
lubricator or other equivalent control device shall be used to allow the
removal of the tools under pressure.
(6) Only employees essential to the conduct
of ongoing operations shall be permitted near the pressurized lubricator, flow
lines, and wellhead.
(7) Wellhead
adapters, wire line valves, and lubricating equipment shall be operated within
their working pressure ratings.
(8)
Hammering or otherwise striking on a pressurized lubricator or connection shall
not be permitted.
(9) A threaded
connection or union on a pressurized lubricator shall not be loosened or
tightened.
(10) When handling the
lubricator with a rig catline, air hoist, or other type of hoisting equipment,
the line shall be snug against a union.
The catline or hoist line shall not be tied in the middle of a section of lubricator.
(11) When breaking a quick-thread union that
is secured with a single bolt, the bolt shall be left in place with at least 1
full nut of threads engaged until after the union has been knocked loose. After
the union has been knocked loose, the connection shall be moved to make certain
the ring seal is broken and pressure has been released.
(12) A lubricator, 26 feet or more in length,
shall be properly guyed or held vertical when in use.
