Orange centrifuge technology onshore.

M-I SWACO centrifuges recover valuable drilling fluid and barite while reducing the total volume of drilling waste that must be transported for injection, disposal, or remediation.

Explore our high-speed, high-volume, small-footprint solutions for recovering more drilling fluids while reducing your environmental impact.

Case Study California Boring Reduces Waste by 32% Using Enhanced Fluid Recycling

Conventional mud recycling system failed to remove fine solids and reduce waste disposal

Product Sheet Centrifuge Packages

Our comprehensive portfolio of high-volume and variable speed centrifuges process drilling fluids to the highest possible environmental and performance standards.

Product Sheet 518 HV High-Volume, High-Speed Decanting Centrifuge

Generate centrifugal forces up to 2,100 Gs.

Product Sheet 414 CENTRIFUGE Barite-Recovery Decanting Centrifuge

Recover 95% of barite and return it to the active system while rejecting finer, low-gravity solids.

Product Sheet CD-500 HV High-Volume, High-Speed Precision-Balanced Centrifuge

Hydraulic centrifuge for low-gravity solids separation and barite recovery.

Case Study 518 HV CENTRIFUGE Replaces the Operation of Two Standard 518 CENTRIFUGES

Low-gravity solids have represented a challenge in the Llanos Orientales basin because of highly reactive clays present in the lithology, resulting in increased well fluid costs due to dilution requirements.
