Completion Operations - Wellsite Inspection and Testing

All inspection and testing shall be performed by contractor's personnel and witnessed by Company's completion supervisor.

The drilling programme shall contain all the necessary information, including contingency measures, to enable the operation to be carried out in the most effective way. If for any reason the programme can not be followed, and the contingency has not been foreseen, Company Base Organisation shall be notified and advice sought.

Receiving Inspection

1) When new completion equipment arrives at the Contractor's Base, the Contractor shall perform an extensive series of mandatory inspections. These include initial visual inspection followed by full function and pressure testing of all relevant equipment.

2) The relevant procedures, applicable standards and specifications used by Camco and Otis, for all completion equipment supplied by them, is detailed in their respective Quality Assurance Manuals.

3) Completion equipment shall be assembled.

4) Tubing arriving at Companies Base shall be packed in designated boxes with appropiate escription on the tubing. Prior to shipment offshore the tubing shall be flushed and when necessary, cleaned inside and outside with steam. The tubing will be again packed in designated boxes for shipment offshore.

Procedure For Well Site Preparation - Inspection and Testing

1) As the tubing arrives on board it shall be measured independently by both the drilling contractor and the company representative using different measuring tapes (measurement should be made with the protectors removed). It is the duty of the WSDE to check that the measurements are being done and from the correct position on the thread. After each layer of tubing has been received on board the figures should be compared and checked for any discrepancies. At least 3 evenly spaced wooden strips should separate each layer.

2) Each joint of tubing shall be clearly marked with paint as it arrives on board. If there is any other tubing already on board it should be ensured that there is no duplication of numbers. New tubing arriving on board should be racked on a different part of the deck to any tubing already on board or at least clearly identified.

3) If tubing of two different OD's or thread connections is received on board ensure that a different colour paint is used for the numbering of each tubing size and that numbers are not duplicated.

4) Tubing accessories required for the completion shall be laid out on deck and the contractor (under the supervision of the WSDE) will number and measure all items. Although it may be normally assumed that certain items are of a standard length, the length of each individual item shall be checked and noted.

5) The WSDE shall check the weight / grade / size and thread of the tubing on board, which should be vendor painted onto the joints, against what the programme calls for.

6) After measuring the tubing each joint should be flushed with water.

7) Check that each joint is clean and scale free (those with scale deposits shall be returned to materials department).

8) Check the threads for damage and scale.

9) Drift the tubing with API drift. Drifts shall be at least 42" long.

10) Apply HP Modified Thread Compound in the case of 13% Cr tubing and Cats Paw Black on all other premium connections to the threads and then replace the pin and box protectors.

Completion Running - Inspection and Testing

General

1) Ensure that all rig pumping lines are thoroughly flushed with filtered brine to prevent having dirt on top of wireline plugs and thus unable to retrieve them. Ensure all pits are clean as well.

2) Ensure that elevator, slips and power tubing tongs are in proper working order, and that the correct dies are fitted. If deemed necessary a stabbing operator shall be used.

3) Do not use pipe wrenches for manual make up of tubing joints.

4) Using a small clean paintbrush or pipe dope applicator, apply pipe thread lubricant sparingly to both pin and box thread, and sealing shoulders.

5) Ensure that the power tongs are set to cut out at the COMPANY recommended torque. If available a unit to control the initial make-up speed is recommended.

6) Record all torque values when running in the hole with the tubing.

7) Drift each joint as it is picked up to the drill floor. Connections shall be protected with protectors with transporting to the rig floor.

8) The responsible person (driller or completion supervisor) shall record the serial number of each item as it is made up to the string, this includes tubing joints according the completion equipment running list.

9) Supervisors keeping a tubing tally should cross check with each other regularly to ensure that the string is made up according to the programme.

10) After the packer sub assembly is made up to the string, the slips and packing elements should be inspected.

11) When carrying out pressure tests, build up pressure slowly, in stages to the maximum required and maintain for the recommended time.

12) All pressure tests shall be recorded on a suitable chart recorder and maintained in the well file.

13) After spacing out, drift the complete string using suitable wireline drifts as specified in the completion installation programme.

Tailpipe X-Over Assembly Inspection

1) Inspect interior and exterior of each component. Ensure that all threads are clean and free from damage.
