GLYDRIL

Advanced polyglycol system

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.

POLYPAC R

Polyanionic-cellulose filtration-control additive

Controls fluid loss in freshwater, seawater, potassium chloride, and salt muds.

GLYDRIL MC

Medium-cloud-point polyglycol

Improve wellbore stability, lubricity, and high-temperature filtration control while reducing dilution rates and bit balling.

POLYPAC UL

Ultralow-viscosity polyanionic cellulose

Controls fluid loss with minimal increase in viscosity in water-based muds.

POLYPAC ELV

Extralow-viscosity polyanionic cellulose additive

Primarily used in weighted systems to avoid uncontrollable viscosity buildup.

DUO-VIS

Biopolymer viscosifier

Small quantitites provide viscosity and weight material suspension in WBM.
