GCS Gly LC is a Glycol Low Cloud Point specialized drilling fluid additive used in water-based mud (WBM) systems for advanced shale inhibition, lubricity enhancement, and thermal stability. Designed for demanding drilling environments, this glycol-based product remains stable and effective even at lower temperatures, making it ideal for operations where conventional glycols may lose efficiency due to clouding.

In drilling operations, reactive shale formations can absorb water, leading to swelling, dispersion, and wellbore instability. Glycol Low 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, reducing torque and drag in complex well profiles such as horizontal and extended reach drilling (ERD). Its low cloud point ensures consistent performance across a wide temperature range, including offshore, deepwater, and high-pressure high-temperature (HPHT) environments.
