DD600 is a water soluble drilling additive that is non -toxic , low -foaming , non – flammable , and biodegradable . DD600 contains proprietary additives to reduce the inter -facial tension between water and soils in the drilling fluid. DD600 also inhibits the hydration of shale particles by satisfying the unbalanced ionic charges in the clays and by forming a protective film that blocks entry of water into the shale.
This protective film prevents hydration of the shale which helps reduce bit balling, collar plugging, sloughing, enlarged hole and hole-fill on trips.
DD600 helps maintain a thin, tough wall cake, and is not affected by sodium content in the drilling fluid.
DD600 can be used in virtually any water-based drilling fluid. It is used primarily in upper-hole drilling to minimize bit and Bottom – Hole Assembly (BHA) balling, to reduce surface tension, and aid in dropping sand and facilitates the removal of drill solids.
