| Summary: | Drilling fluid has a very important role in facing the swelling clay problems. Swelling occurs when the drilling operation through reactive clay formation. Various drilling fluids has been introduced to prevent occurence of swelling, such as OBM (oil based muds), and SBM (synthetic based muds). This kind of muds known well to prevent swelling because it is inert fluids. OBM has a problem relating to the environment. While SBM problematic at initial cost.<p>Water based (WBM) drilling fluid has also been known to prevent swelling by adding certain additives. WBM type more environmentally friendly and low initial cost. Examples of this additives are KCL (potassium chloride), KCl-PHPA (Partially Hydralized Poly Acrylamide), silicate, glycol, and amine based fluid. However, this fluids is not always good so the hydration of clay will still occur and there are other problems. |
