Viscosifiers & Fluid Loss Reducers
Two of the primary functions of any drilling fluid are hole cleaning and cuttings suspension. The introduction of shear-thinning polysaccharide gums was one of the most important technological innovations in the development of water-based muds. Using the appropriate quality gums for the right application allows proper engineering of drilling fluid, cement and spacer properties to ensure optimal flow rates and minimum ECDs for drilling and displacements. OS XANTHAN products are API spec biopolymers with tried and tested performance. OS RHEO GUM and OS RHEO GUM PLUS modified polysaccharides are much more thermally stable and calcium tolerant and have many other benefits compared to Xanthans. Choose the right gum for the right application.
Fluid Loss is one of the fundamental properties of any drilling fluid. It has greatest relevance while drilling porous and permeable formations and especially while in any potential reservoir. It should always be viewed in conjunction with a trend and any associated change investigated and acted upon. OS PAC products are API specification polymers. OS STARTROL and STARTEMP are potato starches with good biological stability and temperature tolerance.
