Generally, Celopro Cellulose Ethers products provide the following properties for the oil and gas industry:
High Salt Tolerance
Fluid Loss Minimization
Furthermore, Celopro HEC as a naturally derived polymer, is easily biodegradable.
The choice of Celopro types depends on the application and the requirements, the most commonly used types are Celopro HHS Grades.
Celopro HEC is used as a viscosifier in brines and saline fracturing fluids, workover fluids, completion fluids and drill-in fluids.
In cementing applications, HEC minimizes fluid loss, enhances retardation of the slurry and modifies its rheology.
