Arctic Directory: Schlumberger introduces MaxCO Acid system

Schlumberger said Dec. 7 that it has released its new MaxCOз Acid degradable diversion acid system. This new polymer-free, non-damaging acidizing system can be used for both matrix and fracture stimulation in carbonate reservoirs with permeability contrasts or natural fractures. The MaxCOз Acid system is designed to be used in oil or gas well in both open-hole and cased-hole intervals, regardless of deviation. Treatment design, execution and evaluation are optimized using Schlumberger proprietary software applications. Applications of MaxCOз Acid yielded a 500 percent production increase from an acid fracturing treatment in the Bluell formation in North Dakota. Elsewhere around the world, productivity increases in excess of 100 percent are frequently achieved, with significant improvements being made to efficiency operations.
