THRUTROL filtration-control additive is a specially modified starch derivative used in the FLOTHRU water-base drill-in fluid system. When used in conjunction with THRUCARB bridging agent and properly sized SAFE-CARB calcium carbonate, it provides a thin, pliable filter cake that minimizes infiltration yet promotes oil production without the need of a chemical breaker. THRUTROL starch has a hydrophobic nature that creates organophilic channels within the filter cake.
