What happened in P&A:
As planned

What Was Planned

Use a standard surface flow tree (SFT)

What Was Learned

The standard SFT is unnecessary big

What Actions Are Required

Plan for using a simplified dual pump in sub. The master and swab valves are not needed so and the flow and kill valves can be 2″. This will reduce the weight and size and simplify the rig up.
