Ecotrol HT filtration-control additive can provide filtration control in all oil- or synthetic-base drilling fluid systems. Ecotrol HT additive reduces the HTHP fluid loss at temperatures up to 260° C (500° F). Ecotrol HT additive is an effective replacement for or supplement to Versatrol HT filtration-control additive. Ecotrol HT additive should be used to replace Ecotrol RD additive when temperatures exceed 190° C (375° F). Ecotrol HT filtration-control additive is added at concentrations between 5.7 to 11.41 kg/m3 (2 to 4 lb/bbl) depending on the fluid-loss-control requirements and the bottom hole static temperature. In some cases, higher concentrations of Ecotrol HT will be required for an efficient filtration control.
