Oil Drilling

HEC is used by the oil and gas industry for various applications such as rheology modification in fluids for drilling and completion of petroleum and natural gas wells.

Also, Celopro Cellulose ethers is used in hydraulic fracturing processes and it is an effective fluid-loss additive in well cements. Celopro HEC is compatible with most additives such as biocides, antifoaming agents, oxygen scavengers, fluid loss control additives and retarders. As a naturally derived polymer, it is easily biodegradable.

Generally, Celopro Cellulose Ethers products provide the following properties for the oil and gas industry:

Rheology Modification

High Salt Tolerance

Fluid Loss Minimization

Clear Solution

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.
