M-I SWACO is the leading supplier of drilling fluid systems, engineered to improve drilling performance, and thus, a vital part of the world's hydrocarbon exploration and production industry. </p>
M-I SWACO offers you proven solutions for any downhole challenges — from the simple to the complex. Innovative drilling fluid engineers are at the company's core, helping oil and gas operators increase efficiency and lower costs. M-I SWACO does 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.
In August of 2010, M-I SWACO became part of Schlumberger, the world’s largest oilfield services company. They were the first to introduce cost-effective, high-efficiency micronized barite technology to water- and oil-based drilling fluids.
