BL-50L (Fluid Loss Additive)

Product Information

BL-50L

Description

BL-50L is a liquid fluid loss additive designed to control the filtrate loss of a cement slurry. BL-50L is an anionic blend of high molecular weight synthetic copolymer that will control fluid loss in cement slurries by absorption and conformation of macro molecules at the solid/solution interface, in other words, it will attach to the cement particles and thicken the interstitial water.

Application

  • The low fluid loss control properties of BL-50L additive are achievable for bottomhole circulating temperatures ranging from 80°F to 250°F.
  • BL-50L can be used in either sea water or fresh water.
  • As BHCT increase, higher concentrations of BL-50L are required due to viscosity thinning of the mix water. A dispersant, BMS’s BD-40L, is used in conjunction with BL-50L to enhance fluid loss control ability.
