RXSOL ORG -15 (Asphasol) shale inhibitor is a partially water soluble, water dispersible blend, containing sulfonated organic resins for water-base muds. It aids in stabilizing shale sections, controlling solids dispersion and improving wall cake characteristics. Being partially soluble, RXSOL ORG -15 (Asphasol) has the capability of plugging micro-fractured shales and sealing shales so that the hydrostatic overbalance from the fluid column is not transmitted to the pore pressure network of shale formations adjacent to the wellbore.
