    RCS 1 contains cationic starch to control fluid loss and to inhibit shale expansion further. RCS 2 is a highly inhibitive version of RCS 1 containing polyglycerol. RCS 3, the most inhibitive mud of the series, contains a phosphate salt and polyglycerol. Levels of inhibition appear close to those of oil-based mud.

    For water-based muds, this mechanism can be controlled by adding a second (dewatering) loop to the mud processing system so that the mud’s water phase can be recycled and the volume of drilling waste minimized. Ultimately, disposal of this waste depends upon the toxicity of mud systems used to drill the well. Therefore, the properties of mud

    2017-12-04· The application of polymer muds has been hindered by two criticisms. First, they are difficult to run because mud-engineering maintenance guidelines are very different from conventional bentonite mud systems. Second, they are less solids-tolerant than dispersed or lime-based systems. Consequently, these muds often have proved uneconomical for drilling geologically young and highly
