Negative Operational LL with Faroe
Brasse (31/7-3 A) – Reservoir section
What happened:
Stuck with wireline toolstring 1A ZAIT-PEX-PPC-MSIP-PPC-NGI-XPT at 2831 m, bottom of toolstring and top of toolstring 2779 m. Pulled tension on winch up to 14000 lbf and helf for 2 hours. No tension seen on cable head, indicatinf cable stuck. Not able to pull toolstring free.
What was planned:
Wireline
What was learned:
The cable head was checked on surface after toolstring ! A was fished and pulled to surface. With 1.5 m cable left on cable head everything was fine electrically.
What actions are required:
Suggest to split run 1A into two runs and perform pressure points on seperate WL run.
