Schedule the van for a visit to your lab and we bring quality parts and outstanding service. For details about our repair service and to download a repair form, visit our servic ...

  • New Industry Training Program

    OFITE is excited to be hosting a new drilling fluids training program at our facility in Houston, TX. Classes are led by David Breeden, a consultant with over 35 years of experience in all aspects of drilling fluids technology, marketing, R&D, and operations. He will be assisted by Larry Mitchell, who has over 20 years of experience with drilling fluid testing equipment and technology. Drilling is a complex operation requiring the combination of different technologies and disciplines. Today’s drilling personnel must have a working knowledge of drilling fluids to effectively drill a well. This course covers all aspects of drilling fluids technology, emphasizing both theory and practical application. Hands-on laboratory exercises are included. Course Objectives Use clays and polymers to achieve desired mud properties Apply water chemistry to the treatment of drilling fluids Perf ...

  • Alkalinity of Drilling Fluids

    Alkalinity is one of the most important chemical properties of drilling fluids. But what it is? And how does it affect drilling fluid performance? Alkalinity is the acid neutralizing power of a fluid. In drilling fluid testing, alkalinity can be measured on either whole mud (designated with a subscript "df") or on the filtrate (designated with a subscript "f"), as collected with a filter press. The data collected from the alkalinity test can also be used to estimate the concentrations of hydroxyl (OH-), carbonate (CO3-2) and bicarbonate (HCO3-) ions in the drilling fluid. Knowledge of the whole mud and filtrate alkalinities is important in many drilling operations to ensure proper control of the drilling fluid chemistry. Additives, particularly some deflocculants, require an alkaline environment to function properly. Alkalinity arising from hydroxyl ions is generally considered benefic ...
