Canyon sand in Sterling, Schleicher, Sutton and Crockett counties has been to balance possible formation damage with completion costs. The recent advent of cross-linked water-based fluids and more effective clay stabilizers has reduced both the screenout problems and formation damage. The ability to transport sand out to the drainage boundary is the ideal stimulation practice for almost any tight sand. This work investigates the theoretical and practical aspects of pumping a complexed weak acid system. This system possesses a large number of the desired characteristics for use in the Canyon sand - high viscosity, low friction loss, low pH compatibility with CO/sub 2/, compatibility with clay stabilizers and fluorocarbon surfactants, low fluid loss, and excellent sand transport properties.
