ECOTROL RD filtration-control additive can provide economical fluid-loss control in all oil- or synthetic-based drilling fluid systems. This additive reduces HPHT fluid loss at temperatures up to 375 degF [191 degC]. It is an effective replacement or supplement to VERSATROL asphaltic resin. ECOTROL RD additive is added at concentrations between 2 and 4 lbm/bbl [5.7 to 11.4 kg/m3] depending on the fluid-loss-control requirements.
Based on unique technology, ECOTROL RD additive has been modified to provide superior high shear stability without polymer degradation. The additive contributes to the fluid rheology by keeping the low-shear viscosity elevated and maintaining some suspending capability of the mud under HPHT conditions.
The additive provides the required synergy between organophilic clays and traditional filtration-control additives to derive the best HPHT fluid-loss performance.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the safety data sheet.
ECOTROL RD additive is packaged in 55.1-lbm [25-kg] multiwall paper sacks. Store in a dry location away from sources of heat or ignition and minimize dust.
