Part 8. Well servicing

Well servicing includes any activity in or on the well including completion, workover, re-entry, plugging, plugging-back, overhaul, logging, sampling, temperature and pressure gauging, fishing, stimulating, acidizing, or perforating, etc.

8.1 BOP requirements

The operator shall install and maintain in working condition blowout prevention equipment in accordance with Part 4 for well service operations on wells capable of flowing and when the tubing bonnet or valve is removed from the wellhead.

8.1.1 Lubricator rating

Lubricator systems must be rated for working pressures that exceed reservoir pressures by a factor of at least 20%.

8.2 Service equipment setback requirements

The operator shall ensure that service equipment is spaced in accordance with Figure 2 and that operations are shut down when wind conditions are detrimental to a safe operation.

8.3 Annular pressure gauge

The operator shall install or have readily available for installation an accurate pressure gauge to determine the well annulus pressure when the well is shut-in.

8.4 Internal combustion / diesel engines

See Part 5, sections 5.5.4, 5.5.4.1, 5.5.4.2.

8.5 Safety valve (stabbing valve)

The operator shall maintain on the service rig in a readily accessible location a full opening safety valve (stabbing valve) in the open position which can be attached to tubing or other pipe in the well.

8.6 Electric wireline operations

A stub lubricator system shall be used during all logging operations in place of a full lubricator on wells that have insufficient reservoir pressures to flow to surface.

8.7 Electrical grounding

The picker, mast unit, or rig and wireline unit shall be grounded to equal the electrical potential between the flowlines, wellhead and all equipment.

8.8 Drill/service sump

See section 3.2.

8.9 Sump/pit closure

See section 3.3

8.10 Record keeping

The operator shall keep a record of all servicing conducted on the well.
