Dewatering

The M-I SWACO dewatering process utilizes polymers to draw fine solid materials together to form larger masses of solids. Afterwards, a decanting centrifuge easily can separate the aggregated solids from the water for disposal.

The dewatering system will process all waste fluids generated during the drilling operations.

These fluids include:

• Drilling fluids mixed with water from the rotary table, mud tanks, mud pumps, generators and any other discharge point around the drilling rig
• Water-base drilling fluid with high content of fine solids, from the mud tanks
• Excess cement slurries when cementing casing (max. 50 bbl)
