Discuss with LWD coordinator during pre-phase meeting regarding download memory data from LWD on last run to lay down tool instead of leaving tools hanging.
Check if modified thread compound in compliance with API 5A3 (e.g. Lube Seal API Modified) is available as it is recommended to be used during winter season, it is required the use of a power tong equipped with load cell and hydraulic fluid suitable for extreme cold weather conditions.
Apply 70% of recommended thread compound quantity on pin and 30% on box covering full thread area, seal surface and torque shoulder.
* Note: for 3SB-ST connections to avoid over doping in cold weather apply dope as normal to pin but only to seal area of coupling.
Liner weight and displacement graphs to be prepared.
Torque and drag graphs to be prepared.
* Confirm required overpull capability
* Pick up 5 ½” S-135 DP (typically 400-500m) as required.
Aluminium spiralizers will be used.
Pip tags to be available prior to running liner.
Use short bails when running 7” casing to help casing centred and not swing when stabbing into box.
Back up shoe, float and landing collars should be available on location.
Gauge the OD of the liner drift provided by Weatherford and confirm with the Operations Engineer that the dimension is acceptable. OD certification should not be older than 12 months.
Randomly selected ten joints of liner should be internally callipered to accurately determine internal volumes. Use the average ID to calculate displacement volumes. Obtain an accurate measurement of mud pump efficiency for pumping cement.
Complete tally of 7” liner and space out the liner to be set ~0.50 m from well TD. Refer to 9-5/8” casing tally or CCL to confirm that setting depth of hanger does not place hanger slips or packer element across a casing coupling.
Confirm reamer shoe design with Operations Engineer.
Confirm pup joint x/o to connect straight from the Top Drive to the cement assembly is available.
The displacement will be made with the cementing pumps, using a dedicated tank. Ensure pump is fully charged prior to displacement and total volume recorded.
Mud loggers to calibrate pit volume indicators and ensure accurate records of pit volumes are maintained throughout liner running and cementation.
The liner string will be rotated while cementing to ensure good cement bond in the liner annulus. Note liner make up torques below.
On the rack attach each solid Aluminium spiralizers with 2 x stop collars as follows:
* One aluminum spiralizer per joint over shoetrack.
* 1 Aluminum spiralizer per joint from ~5106m to ~5050m. Ensure alternate flow direction on alternate joints.
* 1 Aluminum spiralizer per 2 joints from ~5050m to top of liner. Ensure alternate flow direction on alternate joints.
Liner cementing head on location. Confirm with Operations Engineer the following:
* Correct size of pump down plug has been loaded into the Plug Dropping Head Assembly
* The phenolic setting ball has already been inserted in the ball dropping sub.
Calculate space out and make up cementing system ensuring there is adequate space for string manipulation. Lay out on catwalk.
Three DP pup joints of different lengths to be laid out on catwalk.
Pre-job planning meeting with all key personnel.
