Operations Engineer to organise pre-job planning meeting at the rig site, with rig and office personnel to discuss the job objective and hazards.
Sections are picked up in 30-foot lengths, so the steps outlined should be multiplied for a given core barrel length.
Check if hole conditions allow run 81 meter core barrel.
Do not run roller reamer on top of core barrel.
When picking up a section of core barrel fitted with an outer barrel stabiliser using the crane only, the slings should be positioned on the outside of the stabiliser blades. This ensures that the slings are pulling towards the centre of the load, and are prevented from moving inward by the stabiliser blades. (Prevents the load from slipping and causing trapped limbs/blows to the body).
When picking up the barrel using the drill floor tugger and tailing the load in with the crane, the slings should be placed just inboard from the stabilisers as the slings are being pulled away from the centre of the barrel.
When handling core barrel do not hammer the slips as the cotter pins can be parted and button dies fall down the hole and ensure to tap the slips into place. Once dog collar is removed the slips can be visually inspected prior to pulling.
Ensure that all personnel are standing clear of the catwalk when hoisting the barrel from the pipe deck to the rig floor.
Ensure that a tag line is attached to the load to keep control of any swinging.
Make sure no personnel are standing between the core barrel and the pipe racked in the derrick.
Ensure that the elevators are attached to the core barrel before removing the top sling.
Keep hands away from the core barrel body while it is being hoisted by the blocks, as the lower sling may slip.
Control the barrel movement with racking arm/tugger line prior to positioning in the rotary table.
When tripping out with core if gas is associated with the core apply 3 minutes a stand to 500m and then 6 minutes a stand to surface.
When applying torque to the connections on the outer barrel, keep hands away from the core barrel body and stand back from the rig tongs.
Ensure that the barrel is kept securely centralized when applying torque to the connections on the near bit stabilizer and core head. This prevents any possibility of the barrel being pulled out of the rotary table.
