M-I SWACO

A Schlumberger company

MI-SWACO hero banner.

M-I SWACO became a Schlumberger company in 2010. Innovative drilling fluid engineers are at the company's core, helping oil and gas operators increase efficiency and lower costs. We do this by developing drilling fluid systems and additives that accommodate a wide range of drilling environments and demanding applications—including HPHT, deep water and ultradeep water, shale gas, heavy oil, depleted wells, and more.

Proven solutions for downhole challenges—from the simple to the complex

Specialized additives complement the efficiencies of our advanced drilling fluid systems by targeting performance-hindering downhole conditions, eliminating or minimizing the problems that drive up costs and threaten drilling programs. For example, we were the first to introduce cost-effective, high-efficiency micronized barite technology to water- and oil-based drilling fluids.

Tailored fluids and additives for optimal efficiency and reduced cost

Our base fluids and additives are tailored for specific well construction applications. Custom formulation helps you maintain wellbore stability, optimize ROP, and increase overall drilling efficiency while reducing NPT and minimizing HSE footprint.
