Borgland Dolphin
Negative Operational LL with DNO
Oselvar (A-1 H, A-2 H, A-3 HT2) – P&A
What happened:
Clamps holding the control lines (polyoil clamps) had disintegrated. Tubing had to be cut after it got stuck when pulling it with the control lines coiling itself on the between tubing and casing.
What was planned:
Pulling completion (tubing and control lines) after cutting the tubing just above the production packer.
What was learned:
Fishing of control lines is difficult.
What actions are required:
If these types of clamps have been used a tailored fishing package should be made available.
