AVA EXTRA-DRILL AVA EXTRA-DRILL is an environmentally friendly and readily biodegradable blend of organic compounds, specially developed for enhancing the inhibition of shale formations in water-based mud systems. AVA EXTRA-DRILL can be used in fresh water systems where any additions of salts may cause electrical log interference. It adsorbs onto the surface of troublesome shales, increasing borehole stability by inhibiting the dispersion of water-sensitive shales. In water-based mud systems AVA EXTRA-DRILL increases cuttings hardness and decreases mud dilution rates. It improves lubricity, reducing stuck pipe incidents and enhancing penetration rates. If there are no special restrictions, AVA EXTRA-DRILL can also be used in salt systems. Call and let AVA help you design a system to reach your drilling objectives. |
