GLYDRIL MC
Medium-cloud-point polyglycol
GLYDRIL MC medium-cloud-point polyglycol can provide improved wellbore stability, lubricity, high-temperature filtration control, plus reduce dilution rates and bit balling.
Applications
While polyglycols are most effective when used in conjunction with an inhibitive salt, such as KCl, in a nondispersed polymer system, they can be used as additives in most water-based systems. GLYDRIL MC polyglycol is acceptable for most applications specifying low-toxicity additives.
Advantages
- Improved wellbore stability and shale inhibition
- Improved lubricity
- Improved high-temperature filtration control
- Reduced dilution rates and mud consumption
- Reduced bit balling potential
- Low toxicity
GLYDRIL MC polyglycol stabilizes troublesome shales by plugging shale pores, preventing the equalization of hydrostatic pressure away from the wellbore.
