Oil Grade PAC & CMC
Current Location:HOME > Oil Grade PAC & CMC

 

AOSHENG Oil Grade product now includes a full range of poly anionic cellulosics (PAC) and carboxymethyl cellulosics (CMC), which are complying with international standards API. All forms and grades of CMC and PAC are inherently biodegradable. 
Product type & quality specifcation
 
Oil Grade CMC can be used in drilling fluid, and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fracturing fluid, it is used to carry stuffing and avoid fluid loss. “XUEFENGt” Oil Drilling CMC products, divided into high viscosity (HV) and low viscosity (LV)

PAC-HV (also referred to as API PAC regular grade), and PAC-LV are widely used in water-based drilling fluid for a variety of applications, such as filtration control, viscosity and shale inhibition. Although field use can vary, this procedure focuses on filtration-control and viscosity-control characteristics. “XUEFENGt” PAC products, divided into high viscosity (HV) and low viscosity (LV)
