Oceanview Brand Liquid HEC is a nonionic, ultrahigh molecular weight hydroxyethyl cellulose suspended in a homogenous, hydrocarbon-free, biodegradable, environmentally safe mineral oil. Liquid HEC contains 40% or 45% by weight high quality HEC dry polymer, it is used to impart highly shear-thinning rheological properties and suspension in a wide variety of water base fluids. Specifically for reservoir sections, to prevent clay particles from blocking reservoir pores and to protect the reservoir. Liquid HEC is insensitive to electrolytes and will not produce sediment residues in high-salinity environments, making it an excellent reservoir protection agent product.

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
Highly effective viscosifier
Easy to handle and mixes well in low shear rate environments
Increases carrying capacity of fluid
Extremely stable suspension
Excellent environmental acceptability and readily biodegradable
Does not form lumps or fish-eyes. Disperses easily into fresh water or brine with minimum shear
HEC-L 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.
