This paper discusses the theoretical advantages of ultra high sand concentrations (UHSC) in hydraulic fracturing treatments. Results from several treatments are presented. For comparative purposes, results from conventional, lower sand concentration treatments are presented. Mechanical aspects of handling ultra high concentrations of sand (10 lb/gal and greater) at injection rates from 40 to 70 BPM have been a major consideration in conducting these treatments. Sand concentrations, at these rates, have been unattainable in the past partially due to sand handling problems. The capability of handling sand under these conditions has been developed and is discussed.
