Introduction and Well Control Fundamentals 53

1.1.11.2.1 Prejob checks
The supervisor with responsibility for well control will:
• Ensure that any pressure control equipment is in good condition, of
the correct pressure rating and service type, and that all necessary test
certificates are in date.
• Ensure that any diesel operated power packs are in conformance with
zoning requirements.
• Ensure that the equipment is rated for the anticipated service loads.
• Ensure that the contractor’s crew are competent to perform interven-
tions on a live well.
• Liaise between process operators and the intervention crew during
handover of the well, and at any time the program requires the well to
be flowed/shut in.
• Confirm all necessary plant isolations are in place (double valve isola-
tion where appropriate) and documented.
• Ensure that all necessary work permits are complete, and that the
crews are familiar with any permit conditions.
• Where relevant, confirm that the remote (single) well control panel is
properly configured and all members of the crew are trained in its use.
• Confirm that the crew know what to do in the event of an emergency
at the host facility—i.e., muster alarm or abandonment alarm on an
offshore platform.
• Ensure the crew carry out well control drill, and where necessary
report on their performance.

1.1.11.2.2 During a well control incident
The supervisor with responsibility for well control will:
• Confirm the intervention crew have made the well safe.
• Where relevant, inform production staff (control room technicians
and production supervisors). This is of particular importance if the
well control incident is affecting, or likely to affect, the operation of
the production facilities.
• Gather the relevant data and inform the base office.
• Coordinate any necessary remedial action.
The intervention technician at the well site will:
• Take whatever immediate action is necessary to contain a hydrocarbon
escape from the pressure control equipment.
