RPM relative permeability modification technology is engineered to alter the wettability of proppant to neutral, preventing the retention of waterbased fluid in the proppant pack. RPM technology increases the effective fracture length, conductivity and permeability of the pack to hydrocarbons, leading to higher production and increased ultimate recovery.
Remove capillary effects
Most conventional proppant is strongly water wet, exhibiting a contact angle < 90°. This allows for easy wetting and dispersion of the water-based fracturing fluids in the fracture, causing them to become trapped in the pore throats of the proppant pack.
RPM technology alters the wettability of the proppant surface to neutral. This leads to a contact angle of ~90°, which virtually eliminates capillary forces that prevent water and water-based fracture fluids from becoming trapped after fracturing and during production. This leads to an increased hydrocarbon permeability.
