BHA LL with Wellesley Petroleum
Toppand East (35/11-5, 39/11-29S) – Top hole
What happened:
– 9 1/2″ DC need high M/U torque and might need to use rig tongs.
– 9 1/2″ DC needs lifting subs when handling,
What was planned:
Planned to use 9 1/2″ DC in 26″ and 17 1/2″ BHA.
What was learned:
8″ DC should be used in BHA. No need for lifting sub and use of rig tong. Will also save time rigging up.
What actions are required:
Use 8″ DC in Gnomoria BHA’s
