M-I SWACO Drilplex HDD Inorganic Viscosifier
M-I SWACO, a Schlumberger company, offers Drilplex HDD inorganic viscosifier, specially engineered for water-based bentonite drilling fluids to accommodate both maxi and mini HDD rigs. Drilplex HDD allows the formulation of fluids with shear-thinning properties, resulting in a drilling fluid with both dynamic and static carrying capabilities that does not shear degrade at a high shear rate. When mud is not circulating, it instantly reverts to a gelled state, resulting in a high suspending capacity indicated by high, non-progressive but fragile gel strength readings.
