PRODUCT
MAX-SHIELD
Salinity
MAX-PLEX
FUNCTION
Sealing polymer utilized to generate semi-permeable membrane for
shale stabilization. Secondary function is as bridging material in pore
throats of depleted sands to eliminate differential sticking and lost
circulation.
Enhance clay inhibition and general osmotic pressure.
Aluminum and resin complex that works in combination with MAX-
SHIELD to generate semi-permeable membrane and improve well
stability.
