METHOD FOR REMOVAL OF CUTTINGS FROM A DEVIATED WELLBORE DRILLED WITH COILED TUBING

摘要

Method and apparatus for removing drill cuttings (CB) from a deviated wellbore (WB) drilled with coiled tubing (CT), and more particularly method and apparatus for removing "cutting beds" from a significantly horizontal wellbore drill with a downhole motor (M) by creating flow of fluid in the wellbore at a critical flow rate, above a flow rate range designed for the drilling.
