China’s Reliable HEC Manufacturer for the Oil & Gas Sector
1. Introduction In the complex and demanding world of oil and gas exploration, drilling fluids serve as the lifeblood of operations. These engineered mixtures not only cool and lubricate the drill bit but also stabilize the wellbore, transport cuttings to the surface, and balance subsurface pressures. Without the right combination of fluid chemistry and additives, drilling efficiency can plummet and operational risks escalate. Hydroxyethyl Cellulose (HEC) has emerged as one of the most reliable and versatile polymer additives used in drilling fluids. Its ability to increase viscosity, provide suspension stability, and enhance lubrication makes it an indispensable component in both onshore and offshore drilling projects. LANDU, based in China, has established itself as […]
