Glycol High Cloud

GCS GLY HC

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

Product Overview

GCS Gly HC is a Glycol High Cloud Point is a specialized drilling fluid additive used in water-based mud (WBM) systems for enhanced shale inhibition and lubricity performance in higher temperature environments. Designed for demanding drilling conditions, this glycol-based product is optimized to remain effective at elevated temperatures where lower cloud point glycols may not provide optimal performance.

In drilling operations, reactive shale formations can lead to swelling, dispersion, and wellbore instability. Glycol High Cloud Point works by reducing water activity and forming a protective barrier on shale surfaces, minimizing hydration and improving formation stability. Additionally, it enhances lubricity, helping to reduce torque and drag in complex well profiles such as directional and extended reach drilling (ERD). Its high cloud point characteristic ensures stability and efficiency in high-temperature drilling environments, making it suitable for onshore, offshore, and HPHT wells
