High Fracture Conductivity Yields Attractive Results (SPE 20134)


Kolb reports that in the shallow McElroy Field in Texas, stimulation treatments with 20/40 sand resulted in three-fold increases in oil production.  Switching to higher permeability 12/20 sand and increasing pumping concentrations to 10 ppg allowed five-fold increases in rate.


Field tests suggest propped hydraulic fractures designed with high fracture conductivities are cost effective treatments with attractive economic results. With careful consideration to detail, accurate predictions of production response to fracture treatments can also be made. Treatments performed on the Grayburg-San Andres formation in performed on the Grayburg-San Andres formation in the McElroy Field near Crane, Texas have been evaluated to demonstrate these points.
