Shale Inhibitors for Drilling Fluids
Functional class of additives used to reduce shale swelling, dispersion and borehole instability in water-based drilling fluids.
Application
Reactive shale intervals, KCl/NaCl/polymer systems, PHPA and glycol-based inhibition programmes. Chemistry must match formation sensitivity.
