Borgland Dolphin


What happened in Intermediate section:
It took 4,25 hrs to rig it up on Borgland Dolphin. The rigging up of casing tong and FMS slips came in addition to this time.

What Was Planned

Use the Franks FA-1 casing circulating tool

What Was Learned

A first time rig up takes much longer than expected. The rig up procedure from Franks described a rig with horizontal catwalk. Borgland has a steep catwalk, and this made rig up much more difficult.

What Actions Are Required

Make good experience transfer to next crew that will rig up this tool. Dont run this tool unless it is necessary for poor hole conditions.

What Was Done

Took many pictures of rig up, took notes. Had pre-job meeting and communicated to crew that it was important to work safe since this was a new operation for them.

Comments

It is expected that rig-up time can be cut in half with more experience. It is crucial that rig-down can be done faster, as this will happen in open hole, just before the casing hanger is made up (another 1 hr stop in OH).
