CT applications for operations involving pumping a fluid into the well
Use CT to clean out boreholes and perform acid stimulation, reverse circulation, cementing, pressure control, and a variety of other operations that involve pumping a fluid—water- or oil-based—into the well.
Cleanouts
Coiled tubing (CT) cleanouts are used to clean debris and/or particulates from boreholes. Water- or oil-based fluids 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. Wash nozzles are offered in many different configurations, depending on the particular job and preference.
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.
Reverse circulation
- Cleanouts—fluid-based, foam-based, energized fluid–based
- Reverse circulation
- Fluid swab-out
- Well killing
- Pressure control
- Pressure testing
- Stimulation
- Cementing
