Before running any chrome tubulars, a pre-job meeting will be held with all relevant personnel, i.e. drill crew, tong operators, deck crew, crane operator, etc. to ensure that they are aware of their responsibilities.
1) Padding material will be fitted to the V-door and catwalk areas to prevent damage to the tubulars.
2) The power tongs will be fitted with the correct size non-marking dies. 3) Single joint and side door elevators will be fitted with non metallic inserts. 4) Confirm that the torque turn analyser has been correctly set-up.
Note: Calibrate the tong on a spare joint of tubing.
5) Pick up lines to the single joint elevators will be arranged to allow the joint to be stabbed to hang vertically over the hole, so that no undue pull will be exerted on one side during make up.
6) The tubulars will be transferred to the catwalk with thread protectors installed. Nylon slings wrapped around the joints will be used for lifting purposes.
Note: On no account will metal slings be used when handling chrome tubulars. All new tubulars will be supplied with Econowrap LE.
7) Use single joint pick up elevators for handling tubulars onto the drill floor. 8) Tubing slips will be dressed with low stress dies.
9) Care will be taken when setting pipe in the slips to prevent shock loading and impact damage.
10) After removing the thread protector the threads will be cleaned and inspected (if not already done on the pipe deck).
Note: Do not use a wire brush for cleaning chrome thread forms.
11) Any joints with damaged threads will be laid out, and clearly identified (Refer to section 8.2).
12) Apply API Modified thread compound with a friction factor of 1, using an automatic pipe dope applicator (Refer to section 8.2.6)
13) A non-metallic (i.e. plastic) stabbing guide will be used to guide the pin correctly into the box.
14) The joint will be lowered slowly into the stabbing guide to allow the man on the stabbing board, and the man on the rig floor to guide the pin into the stabbing guide. Throughout the stabbing operation the pipe should be kept as vertical as possible. 15) If the stabbing operation was unsuccessful both pin and box threads will be inspected
for damage. If the box was damaged consideration will be given to replacing it. If the pin was damaged the joint will be laid out.
16) After successfully stabbing the pipe the first four or five turns of the make up will be done by hand using a nylon strap wrench.
17) The last turns will be made using a torque turn unit with a graphical torque turn analyser to confirm the correct make up value.
18) The make up speed should be between 3 to 10rpm. Final make up should be at 5 RPM.
19) The running speed will be limited to a maximum of 14 joints per hour. 8.2.8. Retrieving Chrome Tubulars
1) Before retrieving any chrome tubulars a pre-job meeting will be held with all relevant personnel i.e. drill crew, tong operators, deck crew, crane operator, etc. to ensure that they are aware of their responsibilities.
2) As a field matures it is possible that scale deposition may occur in production wells. Some of this scale may be LSA (low specific activity), and special handling techniques and precautions will be required.
3) Padding material will be fitted to the V-door and catwalk areas to prevent damage to the tubulars as they are being laid out.
4) Ensure that the power tongs are fitted with the correct size non-marking dies. 5) Tubing slips will be dressed with low stress dies.
6) Care will be taken when setting pipe in the slips to prevent shock loading and impact damage.
7) The connection will be broken using a power tong at a low speed of 2 RPM.
8) Once the thread has been broken the connection will be backed off using a strap wrench.
9) The threads will be cleaned using a high pressure jet of fresh water, or a quick evaporating petroleum solvent (chlorine free), and then dried. High pressure cleaning equipment must be used in accordance with platform procedures.
10) After inspection of the threads storage compound will be applied, and clean thread protectors installed.
Note: If LSA scale is present closed end protectors will be installed, and the joints clearly identified as being LSA contaminated. The designated responsible person will check all tubing joints for LSA scale contamination, and will ensure that the correct action, documentation, manifesting and notifications are adhered to for shipment of all LSA scale contaminated tubulars.
11) The tubulars will be transferred from the rig floor using nylon slings wrapped around the joints.
Note: On no account will metal slings be used, or hooks inserted into the pin and box ends.
Note: If possible the crane will be used to lift the joints from the rig floor to the transport boxes.
12) Each joint will be clearly marked, and an 'as pulled' tally prepared by the Well Operations Supervisor.
13) Before placing the tubulars in their transport frames they will be flushed with fresh water.
14) Any joints with damaged threads will be clearly identified and laid out for back-loading in a separate transport frame.
15) A detailed report will be prepared by the Well Operations Supervisor on the condition of the recovered tubulars. This report shall contain details of thread damage, corrosion, scale build up, position in well of damaged tubulars, etc., and will be forwarded to the Completions and Workover Superintendent in the Company office. 8.3. EQUIPMENT PRE-INSTALLATION PROCEDURES
The activities outlined below are to be conducted as soon as completion equipment is received on the well site to allow sufficient time to correct for damaged or missing items. 8.3.1. Material Requisition Lists
Confirm that all of the required completion equipment is available on site. Reference should be made to the Material Requisition Lists provided for each individual completion. The Company Supervisor shall verify that the completion equipment, corresponds to the details in the completion programme and has the appropriate correct part numbers, serial numbers and certification.
