A New Alternative Thinner in the Drilling Fluid System

The most important constituent of drilling operation success is keeping the fluidrheological properties within a certain limit to maintain continuing their functions in goodmanner. To achieve that, mud system needs continuous and direct supervision such asmeasuring its rheological treating any deviation values. Viscosity themost property hydraulic program due relation with bottom holecleaning during drilling, thus related rate, so this should be keptbasically ensure hole cleaning high rate at same time.Some chemicals as thinner added keep both viscosity andother standards required limits; these materials have cost,increasing metric cost final well.The aim research test physical chemical for local material, athinner, which tends decrease .Thirty nine samplesof different types are tested native foreign imported materials.The results additive compared concluded that has thesame trend material limit.
