Summary
ZOD-LZOD-H is mixture of polymers and plugging agents formulated to provide excellent filtration loss control performance and borehole wall stabilization. The polymers in ZOD-LZOD-H forms an isolation membrane on borehole wall, thus preventing the drilling fluid into the formation while the plugging agents provide a superb bridging performance. In addition, ZOD-LZOD-H additive improves the quality of the filter cake and provides minimal contribution to the rheology of the mud systems.
Usage range
