LL with PGNiG
Tomcat (6501/10-1) – Intermediate section
What happened:
The deck tally was made without the mitsui numbers, so not possible to control check the lengths. When the casing was racked in derrick the first stands in the deck/racked tally used the deck numbers and the last used the land/mitsui numbers. Made it difficult and time consuming to make the running tally.
What was planned:
Lay out casing and prepare tally for running the 13 5/8” casing.
What was learned:
Make Rack Back casing DOP to avoid confusion.
What actions are required:
For future operations make R/B DOPs.
