Be aware of the operational program to prepare and anticipate future operations.

1.3. Work Permit

The objectives of the work permit are:

• To prepare an operation with all the entities of the site

• Analyze the risks before starting an operation

• Ensure that the work to be performed 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 of the following work (non-exhaustive list):

• Setting up the SUB.

• Greasing of the crown-block (when the mast is raised).

• Weekly control of the mast.

• Lifting the mast.

• Implementation of the TDS.

• Establishment of BOPs.

• Wiring and cutting of the drilling cable.

• Manufacture of drilling mud.

• Emptying a barrel with a transfer pump.

• BOP test (on stump).

• Hot work (followed by a company fire permit when required).

• Delivery of diesel fuel.

• Installation of selective sorting bins (CIW, IRF, fatty waste).

• Cleaning of a basin (with penetration).

• Withdrawal of the TDS.

• Coating of the mast.

• Withdrawal from the BOP.

• Withdrawal of the SUB.

• Removal of dumpsters.

Work in the mast.

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

2. Work Organization

Carry out a round at the beginning of each shift and check in particular (daily check list):

· The pressures of the accumulation unit (KOOMEY unit).

· Ponds.

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

· The pressure of the pulsation damper.

· Watering of the pump pistons.

· Sensor sheave clearance = 5/8".

Must be present on the floor for maneuvers as soon as you arrive at the BHA. Make sure that the stacking and unstacking of the BHA is carried out correctly.

REMINDERTurnaround time is an important issue for most of our customers. However, client has the following safety standards:

• Time is saved on preparing the material for the upcoming operations and not by taking risks with a too fast ascent and descent of the filling.

• The BHA will be prepared in advance to avoid wasting time during stacking.

The organization and distribution of tasks among the sounders are the guarantors of an efficient and safe operation.

3. Maintenance

A regular maintenance of all our equipment is a guarantee for the good progress of the operations and thus a good image of our company towards our customers. It is everyone's responsibility to take care of the maintenance and the general and functional condition of our equipment.

3.1. Greasing

A lubrication book is available in the office of the Head of Station. This notebook indicates which parts must be greased and the frequency of greasing. This book is also intended to note the date of lubrication performed on the equipment.

3.2. Regular precautions

• Check that the kelly valve key is present and properly identified on the drill floor.

• Immediately report to the Site Manager any anomaly(s) or malfunction from the crown- block to the basins via the gangway and the Station Manager's console.

• Check daily the condition of the floor equipment: wedges, safety clamps, screw keys.

Observe the current safety color code on all slings and shackles used.

- Make sure that once a week, when the crown block is being greased, the rigger carries out a thorough inspection of the mast and all its components (cables, bolts, pins, safety devices and gangway). This operation will be carried out under cover of a work permit.

- Ensure that the vibrators are cleaned as soon as the re-drilling or milling operations stop. Once clean, the vibrators must be stopped until operations are resumed. At the DTM, the vibrator screens will be dismantled and cleaned, a light veil of diesel fuel will be sprayed on them to avoid any corrosion.

- Ensure daily cleaning of pump suction strainers during drilling or milling operations and weekly during workover operations.

- Before each operation, check the general condition of the operating tools (e.g. drilling key combs, wedge combs, etc.) as well as the compatibility between the threads of the internal obturators and the seal used.

- Inspect, at the end of each well that required re-drilling, milling or pumping of granite- calcium, the opening of the BOP doors and the cleaning of the interior elements. Check the gaskets of the various shutters. This control will ensure a permanent functional state of this safety equipment.

3.3. Drilling Pumps

During long-term pumping operations, "listen" and inspect the drilling pumps regularly. Pay particular attention to abnormal noises (banging and whistling) and ensure that the lubrication of the liners is done properly.

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

The minimum pressure reading, with the pump stopped and the bleeder open, must be 700 psi. If this is not the case, notify the Site Manager to rectify this degraded situation which could lead to pump deterioration.

4. Reports, reports and instructions

The IADC drilling report is an important and official document. Only the IADC report will be considered authentic in the event of a dispute. It must be clean, well written, without erasures or overwriting and complete.

· This document must be systematically filled out at the end of each shift.

· Do not forget to fill in the mud and safety meeting sections in the notes.

· Respect the written instructions of the Site Manager and the client. At the slightest doubt, inform his superior.

· Never let a situation deteriorate.

· Keep the DC, DP, HWDP trim book clean and up to date.

· Make a sketch with OD, ID, numbers, lengths and thread types of all tubular material lowered into the well, including that of the customer and service companies. The Assistant Station Manager is responsible for this operation.

· Know and respect the instructions concerning the maximum and minimum pulls and poses in drilling and maneuvering. These instructions will be given by our clients and/or by the client supervisor according to the standards of our company or the client company.

6. General maintenance of the site

· Keep the work floor clean and tidy. Ensures and arranges that access and passageways are never cluttered with material.

· Between each operation or different phases of the program, clean, unload and store in its original place the material that will no longer be used.

· Clean and visually inspect the threads and seatings of all degerged reducers or tubulars. Grease the threads of these devices and protect them with thread protectors. Notify the Site Manager if guards are missing.

· Keep the dog house clean.

· Keep the different notebooks up to date. Keep one notebook for each use and do not mix genres.

· Keep the Station Manager's console and gauges clean and free of tools.

· Leave the work area clean and tidy when you take over.

· Leave work tools clean and tidy. Remember to return tools to mechanics or electricians after borrowing.

· Throw away used parts, rags, used gloves, empty bottles. Sort out the waste if the means are available on the site.

· Maintain the cleanliness and tidiness of the locker rooms, the mess hall and the various equipment (microwave oven, refrigerators…).
