Description
It is a specially formulated synergistic polymer blend of water-soluble polymeric compounds and sulfonated lignite. It is specifically designed to work at elevated temperatures and pressure of deep boreholes, for filtration and rheological control applications, i.e., HTHP functions.
It is applicable in most water base drilling fluids, is tolerant of salt and Ca contaminations and is useful in heavily weighted systems. It controls HTHP water loss while stabilizing rheology and maintaining low to moderate gel strength. It has excellent thermal stability of above 200°C.
