Minimize damage to the formation while drilling

M-I SWACO has refined the industry’s most advanced line of minimally damaging and completion-compatible reservoir drill-in fluids (RDFs) and associated additives. Our RDF leadership is cemented with the award-winning PRO Series, which has expanded to comprise some the industry’s most innovative technologies. Advancements include the only RDF that drills with the efficiency of an oil-based drilling fluid but has the completion simplicity of water-based fluids. Another breakthrough technology uses divalent brines as its base fluid and builds viscosity without the use of biopolymers.

We engineer minimally damaging RDF systems specifically to drill and complete the reservoir section in open hole. Our water-based and invert-emulsion RDF formulations are tailored to specific completion techniques, emphasizing completion compatibility and minimal formation damage.

Complementing our RDF systems are equally safe and effective additives that help get the most out of your well.
