Glycol Medium Cloud

GCS GLY MC

High-performance medium cloud point glycol for water-based drilling fluids, improving shale inhibition and lubricity.

Product Overview

GCS Gly MC is a Glycol Medium Cloud Point is a high-performance drilling fluid additive used in water-based mud (WBM) systems for balanced shale inhibition and lubricity enhancement. It is specifically designed for drilling operations in moderate temperature environments, where maintaining fluid stability, controlling shale hydration, and reducing friction are essential for efficient performance.

When added to drilling fluids, Glycol Medium Cloud Point works by reducing water activity and forming a protective film on shale surfaces, minimizing hydration and dispersion of reactive clays. At the same time, it improves lubricity, helping to reduce torque and drag in directional and extended reach drilling (ERD) wells. Its medium cloud point ensures stable performance without phase separation under standard drilling temperatures, making it a cost-effective and reliable solution for a wide range of oilfield applications.
