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:
CleanBore A 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 A surfactant is nonionic and made from natural-based alcohols and starch. It is environmentally friendly and biodegradable. Because it does not have a cloud point, it can be used in wellbore temperature ranges from 80°F to 400°F (27°F to 204°F).
When used with the CleanBore system, CleanBore A surfactant can provide the following benefits:
Helps leave the pipe and formation in a water-wet condition.
Tuned Spacer™ Material is a cost-effective, water-based spacer that
can provide variable viscosity and optimized rheology. For material #'s 12219 (blend) and 100009902 (dispersant). Used in Congo April 2018
Part of the CleanBore™ system, a surfactant that is added to the spacer pill to enhance the cleanout of oil substrates through an ultra-low interfacial tension, helps leave the pipe and formation in a water-wet condition, is applicable over a wide temperature range and is environmentally friendly.
