I am seeing some guidance for supporting data to what/where regions, areas, or specific well types, have stepped to stand out from conventional standard well design i.e. 30" x 20" x 13-3/8" x 9-5/8".

e.g. Opting to hole-enlarge wells, or drill with more optimal non standard bits/casing sizes, in order to deliver a more cost effective, efficient and >loss free, well delivery.

What was the driver, for change? What key hazards and risk did you believe would be better addressed? What were the results?

Any guidance to a before and after case example that can be referenced, also appreciated.

Peter.
