Prospectivity Modeling for Cambrian–Ordovician Hydraulic Fracturing Sand Resources Around The Llano Uplift, Central Texas

摘要: Cambrian–Ordovician strata in Central Texas are a major source of specialty sand for hydraulic fracturing and have potential to play bigger role proppant supply markets around Texas. Sandstone the Hickory Member Riley Formation is suitable compressive strength, as well grain size shape be used proppant. The sandstone forms basal sequence that non-conformably overlies Precambrian basement complex succession terrestrial transgressive marine arkosic quartz arenitic sands silts. quantity location resources Frac Sand district illustrated through geospatial volumetric techniques estimated at 5 billion tonnes material. prospectivity modeling favorable characteristics existing resource locations applied determine new sites development locate quantify abundance prospective natural district.
