Application
Liquid HEC is mainly used as a thickener completion and workover of a price or divalent metal salt system, or no damage to the preparation of drilling fluids, drilling for oil build regional vertical wells, deviated and horizontal wells. Liquid HEC thickener with a high apparent viscosity and dynamic shear and low shear. It controls fluid loss and the formation of a thin cake, decided it will not appear drilling problems. Completely dissolved in hydrochloric acid determines it will not build oil region produced the injury.
Liquid HEC is one of the main thickener, it can be paired with different specifications of CaCO3 plugging sticky ball for leakage formation plugging.
Advantages
Easy to handle and mixes well in low shear rate environments
Works well at any salinity
Increases carrying capacity of fluid
May be poured down drill pipe
No “fisheyes”
Extremely stable suspension
Highly effective viscosifier
No preservative needed
HEC Liquid Polymer is generally packaged in 5-gallon disposable pails, containing a net weight of 40 lb of product (16 lb of HEC) 32 pails per pallet.
Other packaging options such as 275-gallon totes / IBC Tanks are available on request.
