An environmentally site loss circulation mud additive, Kengro X is 100% natural, additive free, biodegradable and can be used regardless of the base fluid of your mud and/or brine, despite the deviation of your well. Kengro X efficiently plugs fractures and pore openings to allow drilling without sticking problems and reduces torque and drag through depleted and high permeability intervals. Designed to create a fast forming, fast reversible, low permeability filter cake through a unique blend of swelling and lubrifying fibrous material, Kengro X can be added directly to the mud system due to its excellent mixing properties. Kengro X does not affect rheology, logging and mud readings.
