POLY-MUD-CF is UDF's clay free polymer drilling fluid or closed circuit system. The purpose of this water base drilling fluid is to control high viscosity and is an alternative to a high solids mud, which slows down drilling rates. Our clay free system is not intended for every well but for those that require a mud weight of less than 11.5 ppg its an ideal fluid system. It exhibits excellent hole cleaning characteristics and accomplishes this at low pumping pressures. It increases drilling rates and when our polymer package is coupled with KCl clay hydration reduction is trivial. Our system is designed to save our clients money and maximize their overall profits in the long run. Consult with a UDF, Inc. technical support specialist for more details and fluid design specific for your well.


U-SUREFOAM-LT is UDF'S stable foam drilling fluid system. This drilling fluid package is ideal in low pressure zones such as those that are seen in West Texas. It has excellent wall building and hole cleaning characteristics. It is a true "no solids" drilling fluid which contains our foaming surfactant, FOAM-ACTANT or FOAM-NONIC. This foaming agent performs exceptionally well at very low annular velocities. Corrosion is avoided by very carefully selecting a suitable corrosion inhibitor that will not counter act with the foam. This is a very critical step in a system of this nature. Due to its low density U-SUREFOAM-LT imposes minimum pressure on the formation which reduces lost circulation. U-PAC and UQ-TROL are used synergistically to provide a sufficient lubricating coefficient, stabilze foam and exhibit low viscosities at the drill bit. Shale inhibitors and additonal lubricants may be added to prevent shale swelling and increase penetration rates respectively. The fact that air, water and small quantities of foaming agent are the primary constituents of this system it is truly an ecology friendly cost effective drilling mud.
