Amphoteric Polymer Fluid Loss Control Additive

Product Description :

OCL-JT is an amphoteric polymer fluid loss control additive that has good inhibition and mighty resistance to calcium and can be used at high temperature. OCL-JT is a water-soluble high molecule weight polymer consisting of anionic, cationic and nonionic groups.

Performance Characteristics :

  • Excellent inhibition capability, can restrain the hydration, expansion and dispersion of shale and cuttings, keep bore hole stability.
  • With perfect fluid loss control effectivity, good resistance to saturated calcium and salt it can be used in freshwater, seawater and saturated saltwater drilling fluids.
  • It is compatible with other drilling fluid additives. While being easily applicable and maintained it requires only low dosages(2%) and thus the cost factor is attractive.
