What happened in Reservoir section:
Drilled 2 x wiper plugs and landing collar in 45 minutes using a milled tooth rock bit. 300 litres of cement was left behind the wiper plugs during displacement.

What Was Planned

Drill shoetrack with rock bit

What Was Learned

Much better performance than when drilling out shoetrack with PDC bit.

What Actions Are Required

Should consider to drill out shoetrack with rock bit for future operations if the distance to coring point is short and can be drilled with a rock bit.
