ECOTROL F

Filtration-control additive

Ecotrol F* filtration-control additive can be used in all oil- or synthetic- base mud systems.

This product has been designed to be readily dispersible into a fluid system through standard mixing equipment, thus minimizing the potential for polymer ‘fish -eyes.’ The product is especially designed to complement the emulsifiers of oil - and synthetic -base mud systems to provide tight high-temperature, high-pressure (HTHP) fluid loss control at a low product concentration. The product has excellent dispersion and solubility in paraffins even at low temperatures and does not plug down hole screens. Ecotrol F filtration-control additive is effective in 100% oil applications at temperatures up to 191° C (375° F).

Applications

Ecotrol F filtration-control additive can provide economical fluid-loss control in all oil- or synthetic-base drilling fluid systems but is particularly suited to paraffin based systems. Ecotrol F additive reduces the HTHP fluid loss at temperatures up to 191° C (375° F). Ecotrol F additive is an effective replacement or supplement to VErsatrol* filtration-control additive. Ecotrol F filtration-control additive is added at concentrations between 2.9 to 11.4 kg/m3 (1 to 4 lb/bbl) depending on the fluid-loss-control requirements.

Based on unique technology, Ecotrol F filtration-control additive has been modified to provide superior high shear stability without polymer degradation.

Ecotrol F filtration-control additive contributes to the rheology of the fluid by keeping the low-shear viscosity elevated and maintaining some suspension capability of the mud in HTHP conditions.

The product has excellent dispersion and solubility in paraffins even at low temperatures and does not plug down hole screens.

Finally, Ecotrol F filtration-control additive enhances the required synergy between organophilic clays and traditional filtration-control additives in order to obtain optimum HTHP fluid-loss performance.
