Recent field experience with shallow, normal pressured wells in South Texas demonstrated an invert emulsion oil mud employed with a polycrystalline diamond compact (PDC) bit significantly increased PDC bit rate of penetration (ROP) and life. Each well used an invert emulsion oil mud from surface casing to total depth and a PDC bit to drill the majority of the same interval. This resulted in substantial cost savings compared to KCl/polymer and freshwater mud systems. To realize the full cost savings potential, hydraulics and mud programs were designed to maximize PDC bit performance and minimize oil mud costs. This paper examines field results and develops a correlation between hydraulics and mud programs and optimum invert emulsion oil mud-PDC bit performance.
