What happened in P&A:
Ran through BOP while jetting from top of BOP and landed out on top of wear bushing without hanging up. Pulled wear ushing free and hung up in lower annular on the way out. Had to work past lower annular.
Rig was all centered prior to RIH and had flushed through BOP at high rate using MPT with jetting sub below.

What Was Planned

Retrieve 9 5/8″ wear bushing

What Was Learned

Issue with annulars on Schaffer BOP’s even when running DQ MPT which is specially design to avoid hanging up in the BOP.
