Multiple Zone Stack Pack System. The Mitchell multiple zone stack pack system is commonly used when two or more intervals are completed in the same well, in one operation. The initial step is to set a sump packer, on wireline or tubing, below the lowermost zone. The lower zone is then perforated and prepped for the prepacking process.

· Summary. This paper describes a technique for horizontal gravel packing of slim, cased holes. The key to the technique is the use of horizontally oriented perforations as a means of providing self-diversion of the gravel pack regardless of fluid leakoff. Traditional horizontal gravel packing requires minimizing fluid leakoff to the
