This paper focuses on the various stimulation designs and treatments performed during the development of the Pecos Slope Field in eastern New Mexico. Information collected from over 125 wells has been categorized and studied in an attempt to determine the best possible stimulation technique for this formation. The Abo sand is a noncontinuous, lenticular, "tight gas" formation which has made evaluation of treatments difficult due to the manner in which these sands were deposited. The evaluation of various stimulation techniques has been summarized by means of calculated skin factors, K, Kh, CAOF and percent decline in the first three months of production. This evaluation will help to determine the preferred fluids, volumes, sand concentrations, rates and other aspects which may or may not play a role in the success of stimulation treatments in this area.
