Checklists

1 Objectives No harm to people or damage to the environment or equipment. Make up and run production tubing along with all down hole equipment first time and with full pressure integrity. Correctly space out of the completion and ensure the tubing hanger can be run, landed, locked and tested on first attempt. Ensure that Completion Operation – Best Practices

When calculating cement displacement consider very cold weather as the efficiency of the mud pumps will be reduced under these conditions. Drilling Contractor to provide an air heater to blow under the cement units before and during the cement operations to ensure no freezing in the cold weather. Ensure that heater is on location and Cold Weather Operations Checklist

Pre-cutting of core Check that the inside of the core barrel is clear of manufacturing or any other residue. Ensure adequate stock of coring consumables are available, plus cradles, saw etc for laydown Hold meeting with geologist, core hand and TP to confirm procedures Before dropping the ball insure that there is no restriction in Coring Checklist

Check casing hanger made up to full length casing joint to facilitate easier handling. Check correct length dedicated landing joint (buttress box top conn.) to screw directly into cement head. Check cement head set up for buttress thread. Casing pup joints need to be a minimum of 3m in length for the Overdrive system. Check Weatherford Overdrive casing running and pick up/lay down machine – Checklist

Contingency – Heavy losses It is recommended not to attempt to drill ahead with heavy losses. LCM pills and/or cement plugs should be set as soon as the losses occurred, so that they can be positioned easily on bottom and across the loss zone. If losses are not manageable, the hole can be opened to 16″ Potential Problems – Best Practices

Making connection Wipe the full stand once by pumping out and reaming back down Wipe the bottom single once by pumping out and reaming back down The driller must nominate a responsible person to control the mud pumps (e.g DD, Toolpusher, AD). This person will be responsible for shutting down the pumps quickly in the 12.25″ guidelines for tripping, making connections and back reaming

Remove casing hanger running tool by rotating to the right (approx 14 turns). Change out bail arms on top drive. RIH one joint of drill pipe. Clean out BOP and wellhead area. POOH RIH with KIOS flushing tool and jet on top of the casing hanger neck. Clean out wellhead. POOH. RIH setting tool and 9 5/8″ Wellhead and BOP Operations Checklist

Completion Engineer to organise pre-job planning meeting at the rig site, with rig and office personnel to discuss the job objective and hazards. Prior to displacing well to a completion fluid, ensure that catch cans and trip tank are clean. Flush choke and kill lines from any loose debris. Wash BOP and pull wear bushing Completion Preparation

Unable to reach setting depth with liner The liner hanger starts to set at approximately 1,400psi / (100 bar) differential pressure. Take care that circulation pressure does not exceed 900psi / (62 bar). If it takes more than 900psi / (62 bar) pressure to circulate. Make sure that the Liner hanger is in tension before 7” Liner Contingency Planning

Hold Toolbox talk on rig floor, to advise all rig-personnel involved of the objectives, summary of the running procedure, and to discuss any particular care or safety concerns. Company Man and Mud Logger to prepare Liner Weight + Metal Displacement Diagrams. Pick up shoe-track sub assemblies and perform floating equipment test. Install pip tags in 7” liner running procedure
