An analysis of over 20 Texas Vicksburg wells demonstrated that high proppant concentrations were beneficial in providing sustained benefits. Case studies in the Devonian, Wilcox, and Hosston formations were shown to provide similar benefit to fracturing with high proppant concentrations.
A unique viscous fluid has been used in fracturing deep, high-temperature reservoirs. By using large treatments and high concentrations of proppants, reservoirs with low permeability and porosity can be proppants, reservoirs with low permeability and porosity can be successfully stimulated. Data from widely varying formations are compared, with special emphasis on the Vicksburg.
