Our portfolio of specially engineered additives is designed to inhibit reactive shales in water-based drilling fluids and systems.

In addition to the shale inhibitors below, we offer POLY-PLUS liquid clay inhibitor, POLY-PLUS RD readily dispersible liquid clay inhibitor, and BLACK FURY readily dispersible liquid asphaltite suspension.

Shale Inhibitors Offerings

POLY-PLUS RD
Readily dispersible liquid clay inhibitor
Eliminate the formation of fish eyes by improving dispersion.
HydraHib
Shale inhibitor
Intercalates and reduces the space between clay platelets so that water molecules will not penetrate and cause swelling
POLY-PLUS 2000
Liquid clay inhibitor
Encapsulate drill solids and stabilize clay formations.
ULTRACAP
Encapsulating shale inhibitor
Limit dilution rates and low-gravity solids loading by preventing clay solids from dispersing into the mud system.
ASPHASOL SUPREME
Sulfonated-asphalt shale inhibitor
Stabilize shale sections, control solids dispersion, and improve filtercakes.
POROSEAL Plus
Latex-based fluid loss control sealant
Seals low-permeability, microfractured formations in shale gas and unconventional plays.
KLA-CURE
Hydration suppressant
Reduces the dispersion and swelling of reactive clay formations.
KLA-GARD
Shale stabilizer and inhibitor system
Reduce the swelling of sensitive shales and drill cuttings exposed to water-based drilling fluids.
IDCAP D
Polymeric shale inhibitor
Adsorbs onto the clay surfaces and prevents cuttings from sticking.
KLA-STOP
Liquid polyamine shale additive
Effectively inhibit shale or gumbo clays from hydrating and minimize the potential for bit balling.
POROSEAL
Copolymeric filtration-control sealing additive
Improves the performance of highly inhibitive water-based drilling fluids.
KLA-HIB
Amine-based shale inhibitor
Inhibit reactive shales by preventing water uptake.
