Summary
ZOD-GreenSeal is a kind of nanometer transformable polymer. It is usually used in water based drilling fluid, in low pressure stratum and solid stratum to decrease filtration and reduce pipe-sticking risk.
Characteristic
ZOD-GreenSeal has good compatibility and dispersability in fresh water drilling fluid system, salt water drilling fluid system and sea water drilling fluid system.
Effectively inhibit hydration expansion of the formation and guarantee the stability of borehole wall.
Usage range
Recommended dosage：1.0~3.0% (BWOC).
