Polyanionic-cellulose filtration-control additive
Controls fluid loss in freshwater, seawater, potassium chloride, and salt muds.
Advanced polyglycol system
The GLYDRIL system uses an enhanced water-based chemistry that employs polyglycol technology, which delivers
The GLYDRIL system can be customized to meet a variety of drilling challenges—large-diameter wellbores, extended-reach drilling, deepwater, and subsalt applications, and particularly reactive shales.
The system also is ideal for drilling high-angle wells in reactive shale formations—where wellbore stability, torque, and drag are major concerns.
