POROSEAL
Copolymeric filtration-control sealing additive.
POROSEAL additive provides permeability plugging to effectively seal shales and filtercakes.
GLYDRIL
Advanced polyglycol system
The GLYDRIL system uses an enhanced water-based chemistry that employs polyglycol technology, which delivers
- high degree of shale inhibition
- wellbore stability
- HPHT fluid-loss control
- lubricity.
Benefits
- In-gauge wellbores
- Lower fluid losses
- Lower potential for differential sticking
- Less torque, drag, and bit balling
- Lower dilution rates
- Slicker, firmer filtercake
- Greater wellbore stability
Applications
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.
