The workover drilling foreman is an experienced worker with recognized training and in-depth knowledge of pulling and workover techniques. His mission is to assist the site manager and lead his team.

1. General Security

 

At the start of each shift, a safety meeting will be held and organized in turn by all the staff. This safety meeting will be written and recorded in the notebook provided for this purpose in order to have support for procedural changes.

–  Familiarize yourself with the operational program to prepare and anticipate future operations.

 

1.2. Working license

The purposes of the work permit are:

–  To prepare an operation with all the entities of the construction site.

–  To analyze the risks before starting an operation.

–  To ensure that the work to be carried out does not interfere with other operations / work.

–  To make the people involved aware of their roles and responsibilities in carrying out the said operation.

 

Establish an internal work permit for all the following works (non-exhaustive list):

–  Rig up/Rig down.

–  Pressure relief and dismantling of the wellhead.

– BOP testing.

– Implementation of BOPs.

–  Installation of the power swivel.

It is imperative to close each work permit at the end of the intervention

 

2. Work organization

Make a round at each start of shift and check in particular:

•    Accumulation unit pressures (KOOMEY unit).

•    The ponds.

•    The positions of the choke manifold, kill line, choke line and stand pipe manifold valves.

•    The pressure of the pulsation damper.

•    Watering pump pistons.

•    Sensor sheave clearance = 5/16".

•    The shunting cable.

•    Weights up and down.

•    The position of the BOP stack.

•    COM commissioning.

You must be present on the floor for maneuvers as soon as you arrive at the BHA. Ensure that the stacking and unstacking of the BHA is carried out smoothly.

 

REMINDER: Maneuvering times are an important point for most of our customers. However the client has security standards which are as follows:

–  Time is saved by preparing the equipment for future operations and not by taking risks with raising and lowering the trim too quickly.

–  The BHAs will be prepared in advance so as not to waste time stacking.

–  The organization and distribution of tasks between the sounders guarantee an efficient and safe operation.

 

3. Maintenance

Regular maintenance of all our equipment is a guarantee for the smooth running of operations and therefore a good image of our company vis-à-vis our customers. It is everyone's responsibility to take care of the maintenance and the general and functional condition of our equipment.

 

3.1. Lubrication

A maintenance sheet for greasing is available in the Site Manager's office. The purpose of this sheet is to record the maintenance carried out on the equipment.

–  Report immediately to the Site Manager any anomaly(s) or non-operation of the crown-block to the basins via the attachment bridge and the shift manager's console.

–  Check the condition of the floor material every day: shims, safety collars, screw keys.

–  Respect the color code for lifting.

–  Make sure that a meticulous inspection of the mast and all its component parts (cables, bolts, pins, safety devices and hooking platform) is carried out after each tripping.

–  Check the suction strainers of the pumps when installing the device.

– Before each operation, check the general condition of the operating tools (example: combs of the hydraulic wrench, combs of the wedges, handling lifts, etc.) as well as the compatibility between the threads of the internal plugs and the gasket used.

 

3.3. Circulation pumps

During long-term pumping operations, "listen" and inspect pumps regularly. Pay particular attention to abnormal noises (knocking and hissing) and ensure that the lubrication of the liners is carried out correctly.

Check the pre-charge pressure of the pulsation damper daily.

The minimum pressure read, pump stopped and purge open, must be 500 Psi. Otherwise, notify the Site Manager to rectify this degraded situation which could lead to deterioration of the pumps.

 

4. Report, readings and instructions

•      Systematically complete the daily report at the end of each shift.

•      Respect the written instructions of the Site Manager and the client. If in doubt, notify your supervisor.

•      Never let a situation deteriorate.
