Completion Fluids

Minimally damaging, HSE-acceptable completion fluid technologies

M-I SWACO provides minimally damaging clear-brine completion fluids for all downhole environments. Our blends of completion fluids are customized for specific applications and take into consideration density, true and pressurized crystallization temperatures, and clarity. Our portfolio includes cesium formates that are the standard for balancing HSE and operational considerations in high-pressure, high-temperature (HPHT) and similarly challenging environments.

The SAFE series of completion fluid additives illuminates our focus on protecting your reservoir and maximizing production. These minimally damaging additives include displacement and cleanup chemicals, viscosifiers, filtration aids, scavengers, surfactants, and corrosion inhibitors.
