Hydroxyethyl cellulose

CheSilo HEC in oil-drilling.

 

In oilfield applications, hydroxyethyl cellulose (HEC) is the preferred rheology modifier for workover/completion fluids since 

it helps provide clear, low-solids fluids that impart minimum formation damage,unlike some competitive polymers. 

It has applications in cementing and fracturing, as well as an additive for nondispersed muds, in brine fluid thickening, 

as a fluid loss controller, and reducer of hydraulic friction, among other things.
