MEGADRIVE F Fluid Loss Control Additive | SLB


Fluid loss control additive

Schlumberger Oilfield Services

MEGADRIVE F fluid loss control additive is suitable for use in all paraffin-, mineral oil-, diesel-, or synthetic-based drilling fluid systems. It is a cost-effective supplemental fluid loss reducer and is temperature stable up to 350 degF [177 degC]. In new fluid systems, MEGADRIVE F additive is applied at concentrations ranging from 0.5 to 5 lbm/bbl [1.4 to 14.3 kg/m3], depending on the desired fluid loss control requirement, temperature, type of base oil, and other components of the system. Further treatments with the additive will enhance the filtration control properties of the drilling fluid system. Treatments on existing fluids should not exceed 1-lbm/bbl increments and should be thoroughly pilot tested prior to application.

MEGADRIVE F additive does not require special mixing equipment; it is easily added directly to the drilling fluid system through the mixing hopper and passes freely through shakers with minimal retention. Unlike solid filtration-control agents, MEGADRIVE F additive minimizes the volume lost over the shakers.
