One of the primary concerns in completion practices for the Canyon sand in Sterling, Schleicher, Sutton, and Crockett counties has been to balance possible formation damage with completion costs. The low productivity and, until very recently, the low gas prices for this area have made the use of exotic fracturing treatments very difficult to justify. The fluids were normally a gelled water or gelled weak acid system, often used with CO/sub 2/. In those instances where the treatments are performed via tubing, low injection rates often contributed to screenouts. The recent advent of cross linked water based fluids and more effective clay stabilizers has reduced both the screenout problems and formation damage. Within the last 8 to 12 months, a complexed weak acid system has been developed which has demonstrated a combination of most of the advantages of the other systems with very few disadvantages.
