Proper load-out of casing at docks or staging area

 

·         Compare the casing program against the equipment received: thread types, length, size (OD & ID, drift), grades & weights.

 

·         Ensure that threads are properly treated and protected prior to loading.

 

·         Ensure proper space-out joints with the appropriate threads and crossovers for landing casing are available.

 

·         Confirm overall casing delivery quantities against measured setting depth.   Include excess pipe.

 

·         Verify proper casing handling materials is at the site.

 

·         Ensure information is provided for special threads handling.

 

·         Ensure visual inspection of all tubulars for condition and integrity.

 

·         Inspect casing spool and associated equipment.

 

·         Confirm proper sizing for all casing head hardware, casing hanger and associated equipment.

 

·         Confirm that all necessary certifications are in hand, i.e. lifting, conformity, pressure testing.

 

Pre Running Checks

 

·         Conduct Tool Box safety meeting for safe off-loading and handling of casing.

 

·         Inspect racking area, variable deck load requirements and limitations within the area (i.e., point loading), proper and safe racking materials, shims, etc

 

·         Inspect crane, harness, and all handling equipment.

 

·         Confirm crane certification and operator qualifications.

 

·         Inspect casing spool and associated equipment.

 

·         Ensure proper sizing for all casing, casing spool equipment, casing hanger and associated equipment.

 

·         Review any special equipment requirements including bales, Tam packer, Reagan FSOC, fill up device, etc.

 

·         Ensure casing is properly and safely restrained.

 

·         Unload, number, and tally measurements for all tubulars, obtaining two independent tallies for verification purposes. Specify how the tally is to be obtained. (i.e. measured from where to where.)

 

·         Make a casing running list.  It should clearly state which joint numbers are to be run and left out.  Total each case.

 

·         Confirm weights, grades and drift of casing.

 

·         When possible, drift with largest diameter tool anticipated to be inserted into the casing at its minimum ID.  For example, drift with actual bit verification within the heaviest joint of casing.

 

·         Ensure proper subs and handling tools have been received.  Ensure all have recent inspections.

 

·         Ensure casing with centralizers or other hardware will pass thru spider slips.

 

·         Review any well plan shoe track requirements.

 

·         Install float equipment with shoe track, thread lock as appropriate.

 

·         Install centralizers on pipe rack if possible.

 

·         Install centralizers between stop collars or between stop collar and casing coupling. Install one centralizer above and below stage cementer.

 

·         Inspect the casing internally / externally for corrosion / rust, and issue a report, if deemed necessary.

 

·         Slings and handling tools for backloading at rig site.

 

·         Drift tools for casing string, hangers and work string as appropriate.

 

·         Pickup and lay down equipment as required.

 

·         Proper cementation aids:

 

 

1.     Sufficient personnel to complete the casing running operations.

 

2.     Confirm functioning float equipment and cementing equipment when required. Refer to: Cementing Casing Checklists

 

3.     Confirm type of float equipment; shoe, collars (type - rotatable, non-rotatable, PDC drillable, etc.)

 

4.     Wiper plugs launcher as required for cementing head and associated equipment.

 

5.     Install float collar on pin end of casing joint.

 

·         Install centralizers on pipe racks.

 

·         Conduct verifications of required personnel and handling tools for running casing.

 

·         Consider strongly have a 9 5/8”, 53.5 lb/ft casing spear on location when running casing.

 

·         Function test torque assurance equipment to ensure proper makeup.

 

·         Have casing thread X 2" Weco thread half circulating swage and a casing thread X 4 1/2" if circulating swage on hand on the drill floor.

 

·         Service company verification of any special landing/testing tools.

 

·         Ensure back up casing running tools are on location, inspected, and operational prior to commencing running casing.

 

·         Do not forget to retrieve the wear bushing.
