formulation of drilling mud from nigerian clays

Novel Formulation of Environmentally Friendly Oil Based Drilling Mud

In general, OBM are drilling fluids which have oil as their dominant or continuous phase. A typical OBM has the following composition: Clays and sand about 3%, Salt about 4%, Barite 9%, Water 30%, Oil 50-80%. OBM have a whole lot of advantages over the conventional WBM. This is due to the various desirable rheological properties that oils exhibit.
