SHALE-PLEX™ is a water-soluble drilling fluid additive used to improve cuttings and wellbore stability by reducing pore pressure invasion and destabilization of the shale matrix. The benefits of SHALE-PLEX are enhanced when run in conjunction with TERRA-COAT™ or MAX-SHIELD™. As part of the PERFORMAX™ or TERRA-MAX™ systems, SHALE-PLEX provides a barrier to pore pressure transmission (PPT). Controlling PPT is essential for preventing wellbore breakout and the host of problems it can cause.
SHALE-PLEX formulations are less abrasive than silicate muds and provide improved lubricity.
