Product Description

CLAYGARD® shale inhibitor is a low-molecular-weight amphoteric polymer used to inhibit hydration of reactive clay and reduce swelling of sensitive shales exposed to water-based drilling fluids. It is suitable in fresh water, seawater and high salinity brines up to 400°F (204ºC). CLAYGARD® works to minimize problems such as excessive dilution rates, increased torque and drag, high surge and swab pressures and bit balling. It can be used in mud systems containing low concentrations of active solids, bentonite-free systems or freshly built low-solids systems containing a minimum amount of pre-hydrated bentonite.

Applications/Functions

  • Improves wellbore stability and shale inhibition
  • Improves drill solids removal
  • Reduces bit balling potential

Advantages

  • Effective in most water-based drilling fluids
  • Suitable in high salinity brines
  • Completely water soluble
  • Environmental-friendly and low toxicity

Typical Properties

  • Appearance: Light yellow viscous liquid
  • Specific gravity: 1.1
  • Flash point: 200°F (93ºC)
  • pH: 6.5-8

Recommended Treatment

  • A typical treatment range is4-8ppb (11.4-22.8kg/m3).

Package

  • 55GAL (208L) DRUM or 200KG DRUM
