coiled tubing drilling surface setup
08 November 2019
Dear All,
I'm looking for a good guide and recommendations about Coiled Tubing Drilling for milling out cement plugs and composite bridge plugs in 4.5" Liner through existing 4.5" completion string (set in 9-5/8" casing).
Since EMW is around 17.8ppg (P=5320psi) and there are open perforations between the plugs I need a good surface setup to separate returns (brine, oil, gas) at the surface (we will use water or 1.05ppg brine during drilling).
Regards,
