The SAA is a cup type selective tool specially designed to isolate and selectively acidize pre-determined intervals of perforation. The SAA will isolate intervals to any length by the addition of standard tubing pups joints. The SAA utilizes a simple design with heavy duty cups for reliable, proven operation and a large annular bypass to ease running and retrieving.
The SAA assembly is normally ran into the well with a circulating valve open to a position just above the perforated interval to be stimulated. The circulation valve is closed to pressure test the SAA’s complete assembly. Opening the circulation valve will equalize the tubing to annulus. The SAA tool can now be moved to the desired interval to be treated. Then, after the stimulation fluid is circulated down and the valve is closed, the treatment can be performed.
