Negative Operational LL with DNO

Oselvar (A-1 H, A-2 H, A-3 HT2) – Production section

What happened:

The results from the pressure test caused some initial confusion regarding if the test was successful or not.

What was planned:

Formation pressure testing to qualify Hordaland creeping shales s as permanent barrier elements.

What was learned:

The test criteria set in the DOP was too strict (30 bar pressure test wih 1.72 sg OBM in the well), a max surface pressure of 14.29 bar was later deemed acceptable. It is important that the minimum acceptable pressure is stated in the DOP and that the formation testing specialist is on duty so that any problems can be discussed with the rig and solved immediately.

What actions are required:

Update as done DOP.
