Shale Inhibitor SAS is a versatile, total mud conditioner that stabilizes shale formations, significantly increases lubricity, and lowers HTHP filtration. SMD Shale Inhibitor SAS enhances filter cake properties in both oil and water based muds.

Application/Function

SAS can be used in most water-based and all oil-based and synthetic muds.

Advantages

• Controls water and oil solubility to effect best chemical and physical performance
• Minimizes damage to productive formations
• Reacts with shale to prevent or stop sloughing and swelling
• Significantly increases lubricity; either alone or synergistically with small amounts of oils and synthetics
• Inhibits dispersion of drilled solids
• Will not leave oil slick, sheen or rainbow on water at offshore locations

Recommended Treatment

Add SAS in concentration of 2.0 to 17.0 kg/m3 (0.7 to 6.0 lb/bbl) to any system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
