What happened in Reservoir section:
Reduced torque when drilling out shoetrack resulting in less efficiency.

What Was Planned

Drill out shoetrack efficiently.

What Was Learned

TT550 connection has worked without any problems so far, but we have to be gentle while drilling shoetracks and torque limiter is set to 25 kNm while drilling out shoetrack in case backing out connection. This means that more time is used for drilling shoetracks.

What Actions Are Required

Evaluate the need for wired pipe and drill with 5 ½ FH instead (also ref. row 16,17 and 33).
