Water-based mud additives (WBM)
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.
