Borehole Cementing
Hydroxyethyl cellulose ether (HEC) enhances drilling and cementing by improving mud thickness, stability, and carrying capacity, which prevents water invasion into the oil layer and stabilizes production. It also provides filtration control by forming protective filter cakes on well walls, reducing fluid infiltration, and preventing collapse. HEC lowers hydraulic friction, reducing pump pressure needs and increasing flow rates, while its temperature stability ensures performance in high-temperature wells. In cementing, HEC controls water loss and protects cement integrity, increasing overall efficiency and safety.
