The CleanBore™ system consists of four fluids that help provide quick and effective cleanout of oil-based mud (OBM) so that perforating or production in completion operations can begin. The following fluids are used in the system:
- Spacer pill
- Gel pill
- Brine pill
- Solvent pill
CleanBore B™ surfactant is added to the spacer pill to enhance the cleanout of oil substrates through an ultra-low interfacial tension. The addition of the surfactant also helps prevent the formation of highly viscous emulsions that could affect fluid transport and increase pumping pressure.
CleanBore B surfactant is a clear, colorless liquid packaged in 5-gal pails. It is environmentally friendly and biodegradable.
When used with the CleanBore system, CleanBore B surfactant provides the following benefits:
- It helps leave the pipe and formation in a water-wet condition.
- It helps provide effective wellbore cleaning
- It is environmentally friendly.
