• 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 ...

  • Cement Gel Strength

    Gel strength is a property of cement slurries that describes the attractive forces that exist between particles suspended within the mixture. Gel strength develops as the slurry remains under static conditions. Of the four rheological models that describe the flow behavior of fluids, the one that is used to best describe cement slurries is the Bingham-Plastic model. One of the particular characteristics of a Bingham-Plastic fluid is that it has a yield point. Below a fluid’s yield point, the fluid behaves as a solid. As force is applied to the slurry, it does not move. Once the force exceeds the fluid’s yield point, the fluid begins to flow. As long as the slurry remains in a static state, it has a chance to develop gel strength. Cement service companies have a strong interest in cement gel strength. Gel strength describes the ability of a fluid to clean the walls of the hole and carry ...
