The base fluid may be fresh water, seawater, brine, saturated brine, or a formate brine. The type of fluid selected depends on anticipated well conditions or on the specific interval of the well being drilled. For example, the surface interval typically is drilled with a low-density water- or seawater-based mud that contains few commercial additives. These systems incorporate natural clays in the course of the drillin...

    In many areas clear water cannot be used as a drilling fluid because of its effect on formations and the lack of sufficient viscosity to properly clean the hole. In these circumstances Non-Dispersed Polymer Muds may be used to closely simulate the drilling characteristics of clear water. Non-dispersed Polymer muds have found their best

    The three main categories of drilling fluids are: water-based muds (WBs), which can be dispersed and non-dispersed; non-aqueous muds, usually called oil-based muds (OBs); and gaseous drilling fluid, in which a wide range of gases can be used. Along with their formatives, these are used along with appropriate polymer and clay additives for
