Wellbore Strengthening Additive AC-WBSHIELD
AC-WBSHIELD is an oil in water polymer emulsion whose internal phase is polymer and external phase is water. The particle size of emulsion droplets is between 20-500 nm (in the particle size distribution, more than 90% is below 200 nm). Through particle size matching, it can be used to seal the micro fractures of the formation,especially for drilling in shale gas&oil formation with micro fractures.

Acid thickener AC-CHJ50
AC-CHJ50 acid thickener is an organic cationic polymer synthesized by copolymerization method.It can quickly dissolve and increase viscosity in acid solution, and can resist high temperatures above 120 ℃. It has good compatibility and outstanding friction reduction performance, and can effectively play a role in slowing down, reducing drag, and thickening to improve the depth of acidizing.
