Negative Operational LL with Wellesley
Kallåsen (35/12-6 S) – Reservoir section
What happened:
Junk was found in core barrel (piece of coiled copper plated spring steel). Possibly a piece of spring from float shoe or collar.
What was planned:
Cut core
What was learned:
Got near 100% recovery, but junk could have jammed off at the start of the core. If it was from floats then one should consider a dedicated rock bit/fishing run to drill out shoetrack with junk subs, magnets etc. If we know we are going to core below 9 5/8″ shoe this junk was there after drilling from the shoe to core point at 3013 m.
