Paper: Canyon San Stimulation Treatment Comparison Optimization

From its first development in the early 1960's an effort has been made to optimize a stimulation procedure for the Canyon Sand formation in Southwest Texas. Many attempts have been made to find a fluid system that would maximize stimulation results while minimizing treatment cost and formation damage. As a result, a variety of fluid systems have been pumped consisting of a wide range of both fluid and proppant volumes. This paper investigates historic stimulation practices over eight selected study areas. These procedures are then evaluated based on long-term production data in an attempt to identify an optimum treatment size, for each area, in terms of both fluid and proppant volume.
