Significantly increased volumes of proppants have been placed in carbonate reservoirs such as the San Andres formation in the Howard Glasscock field in Howard County, Texas. The treatments that have been performed were accomplished using significantly smaller volumes of liquid. The treatment placement success can be attributed to the incorporation of recent advances in wireline inputs, perforating techniques, and computer design capabilities using accurate reservoir data. New blending equipment capable of computer interaction has also contributed to the ability to accurately schedule and place the higher proppant concentrations.

The use of the previously mentioned components have resulted in controlled fracture heights while taking advantage of in-situ stress barriers. The greater created fracture conductivity will allow for increased production of fluids once this waterflood has been completely implemented.
