Fluids engineered for the most demanding applications

M-I SWACO oil-based drilling fluid systems are designed for demanding applications, including those requiring the highest degree of inhibition and thermal stability. Our portfolio includes oil-based drilling fluids engineered specially for technically challenging, yet cost-conscious applications, such as the onshore and shelf markets.

Depending on the application, our oil-based drilling fluids can be formulated with a variety of base oils, including low-toxicity mineral oil. Our customized oil-based drilling fluids deliver the utmost in performance in conventional and unconventional drilling applications by

• Maintaining wellbore integrity
• Delivering high ROP
• Reducing NPT
• Tolerating contaminants
• Generating high HTHP stability
• Lowering project costs
• Providing excellent lubricity
