Product Description
PANS is the polymer fluid loss additive of amphoteric and temperature and salt resistance using redox initiator system by AM, AA, AMPS, SA and DMDAAC with water as solvent. PANS can reduce the filtration loss, improve the mud cake quality, has good ability of high temperature resistance, salt and calcium contamination resistance. PANS has low viscosity to mud system due to narrow molecular weight scale. It is especially suitable for freshwater, saltwater, seawater drilling and completion fluids. The recommend dosage is 3.0 – 7.0ppb.

Features
Low viscosity effect, can be used for high density drilling fluid due to slight impact to rheology.
Reduce filtration effectively with low dosage.
Improve mud cake quality and inhibit clay dispersing.
Perform well up to 170 ℃, can be used in deep wells.
Resist salt to saturation and resist calcium and magnesium well. It can be applied in freshwater, saltwater, saturated saltwater and seawater drilling and completion fluids.
Pilot test is recommended before its used in KCl and Polyamine and other strong inhibition drilling fluids.
