BLACKTROL® is a liquid asphalt dispersion form blended with additives and surfactants. It is used as a borehole stabilizer and sealing agent to bridge the pores and micro-fractures and to create an effective barrier that prevents destabilizing pressure transmission into the shale.

Water-based mud additives (WBM)
Hi-Temp versatile tall oil pitch based fluid loss control agent specifically designed to provide superior wellbore stability in adverse bottomhole environment (thermal stability up to 220C). Drilling fluid cost is usually lower due to the versatility of the product: expensive synthetic polymers can be eliminated from the mud formulation.

OPTITROL® is a Tall Oil Pitch based versatile fluid loss control agent designed to provide superior wellbore stability as well as stable fluid loss and rheological properties of the drilling fluid even at bottomhole temperatures up to 2200C

Natural non-ionic polymer readily soluble in fresh and saltwater environments. Used in drilling muds to reduce mud filtrate in most water-based systems. CLEAN-STAR consists of two types of polysaccharides: amylopectin and amylose. During the manufacturing process pregelatination occurs: the starch is heated until protective amylopectin coating is ruptured and inner amylose is released.

G-DRILL® is a polyglycol shale inhibitor. Protects clay minerals from swelling. “Clouds out” within the shale matrix and causes pore plugging and preventing pore pressure transmission. Promotes cuttings integrity, helps their disposal at the shale shakers. Improves mud lubricity and anti-balling properties.
POLYTROL® is a new generation organic polyamine shale inhibitor – ether amines. It is a key inhibitive ingredient of the new HPWBM - high-performance water-based muds. This type of mud has comparable inhibitive properties to oil-based mud (OBM).
KLA-FREE® - liquid polyamine shale inhibitor. It is a mildly cationic low molecular weight polymer supplied as a highly active aqueous solution. Protects water-sensitive shales and clays by decreasing the shale tendency to absorb water, suppress clay minerals hydration. Inhibition mechanism is similar to K+ ions, but in this case NH4+ plays a role of an agent that suppress interlayer water absorption.
