Clear-Brine Fluids

Minimally damaging completion brines

M-I SWACO offers a comprehensive portfolio of clear-brine fluids that are displaced in the reservoir once the drilling phase has been completed. These completion fluids are designed to minimize formation damage and control reservoir formation pressures.

Our clear-brine completion fluids are typically prepared with soluble salts for density but can also be formulated with acid-soluble weighting materials or micronized particles. These fluids are blended to certain specifications to take into consideration densities, TCT (freeze points), PCT (pressure/temperature freeze points), and clarity.

Among our clear brine fluids are specially engineered potassium, sodium, and cesium formates.
