Drilling Fluid Systems


Whether your next well is in a high-temperature, high-pressure environment, in the deepwater with the ever-present threat of gas hydrates, or in a depleted reservoir, we can customize a system to fit your application.

We provide the industry’s most comprehensive line of drilling fluid systems, all aimed at reducing your drilling costs, increasing production and minimizing HSE impact. And, while we are the industry leader in introducing new systems for the technological demands of tomorrow, we are constantly pushing our existing systems to higher levels of performance.

Name Function/Application
DRILPLEX The DRILPLEX system delivers exceptional performance in a multitude of applications and does so in one, easily engineered, cost-effective and environmentally sound package.
DURATHERM The DURATHERM system is a low-colloid, contaminant-resistant water-base fluid designed for high-temperature drilling.
ECOGREEN ECOGREEN, our ester-base synthetic fluid system, is one more example of M-I's uncompromising pledge to balance superb downhole performance with environmental stewardship.
ENVIROTHERM The ENVIROTHERM system is a chrome-free, environmentally advanced fluid designed for high-temperature drilling.
GLYDRIL The GLYDRIL systems, a family of glycol-enhanced fluid systems, deliver performance beyond that of conventional polymer and other water-base fluids.
K-MAG The K-MAG system, used for drilling troublesome shales, provides good shale inhibition and wellbore stability as it minimizes clay migration, swelling and dispersion.
NOVAPLUS The low-viscosity, internal-olefin-base NOVAPLUS synthetic drilling fluid is ideally suited for drilling in deepwater and environmentally sensitive areas.
PARADRIL The paraffin-base PARADRIL system provides good hole cleaning, superior return permeability, minimal formation damage and excellent wellbore stability that help maximize production and lower costs.
PARALAND The paraffin-base PARALAND drilling fluid system is designed to allow the optimized land-based disposal of drill cuttings.
POLY-PLUS The polymer-base, POLY-PLUS PHPA system is designed for improved cuttings encapsulation and shale stabilization.
RHELIANT The RHELIANT 'Flat' rheology system is designed to manage ECD without sacrificing hole cleaning ability or promoting barite sag.
SILDRIL The SILDRIL system capitalizes on the very latest in silicate technology to give performance approaching that of oil mud, but with the environmental acceptability of a water-base fluid.
TRUDRIL Its inherent lubricity, borehole stability, enhanced hole cleaning and low ECDs help make the TRUDRIL system an easily engineered system that is an ideal alternative to an invert-emulsion fluid.
ULTRADRIL With ULTRADRIL™, M-I SWACO has given the industry a field-proven, water-base drilling fluid that provides outstanding shale inhibition and drilling performance characteristics previously associated only with invert emulsion systems.
VERSADRIL The VERSADRIL diesel oil-base drilling fluids system, designed for wellbore stability is contaminant resistant and solids tolerant.
