Our Solutions for Drilling and Completion Fluids

We offer a broad portfolio of specialty chemicals designed to support and enhance the drilling process. The focus is on high performing, temperature stable, and contamination tolerant products for drilling fluid systems. Applications Bentonite Extenders As high-quality bentonite reserves become scarcer, it is common practice to add a small amount of polymer to the ore during milling, in order to guarantee that the bentonite will meet the API specification of minimum barrel yield without compromising fluid loss control. Viscosifiers Essential additives which establish the right carrying capacity to move cuttings and other debris away from the drill bit, help maintain the correct pressure in the borehole, and lower filtration. In most muds, either the incorporation of bentonite, drilled solids, or a combination thereof, will help achieve a barrier to fluid loss by forming a thin filter-cake in the annulus of the well. Fluid Loss Additives Drilling muds are under considerable pressure as they carry the weight of hydraulic fluid above them. They can therefore lose water to permeable zones causing a number of issues.

Shale Inhibitors When encountering shale during drilling operations, water in the drilling fluid may interact with the clay materials within the formation, causing the shale to swell. This can lead to instability in the wellbore, and dispersion of shale into the drilling fluid (sloughing), eventually leading to hole washout. Thinners In water-based muds, as incorporation of drilled solids progressively influences the mud rheology, it may be of significant benefit to reduce the viscosity of your drilling fluid using a thinning agent (deflocculant). Biocides Myacide® / Protectol® are non-oxidizing organic biocides and function primarily by altering the permeability of the cell walls of microorganisms and interfere with their biological processes. Non-oxidizing organic biocides are less prone to cause corrosion than oxidizing biocides. Dewatering Additives Water-based drilling fluids can be disposed of in an environmentally acceptable and more cost effective manner when they are first separated into an aqueous phase and a sediment phase. It is well-established that solids, in particular fines and ultra-fines, can cause severe problems in drilling fluids when allowed to accumulate. These solids can be controlled to a limited degree through the use of mechanical equipment such as shale shakers, desanders, desilters, mud cleaners and centrifuges.
