Prime Offshore Services Coiled Tubing (CT) cleanouts are used to clean debris and/or particulates from boreholes. Water- or oil-based fuids can be used mixed with nitrogen if required. Most cleanouts are done with a simple BHA consisting of a connector, a double check valve, and a wash nozzle. Other options for cleanout tools include: • mandrel bypass tools when gas lift mandrels are included in the well completion • packer jumpers when difficulties are encountered in passing through restrictions • positive displacement motors and bits.
