Semi-analytical approach to the determination of fracture permeability

Abstract Proppant is one of the major elements a hydraulic fracture process that can influence productivity an oil or gas well. The permeability propped may be determined through laboratory measurements, utilizing experimental relationships, using analytical methods. All methods have their advantages and disadvantages, this study attempts to offers solution combines various achieve practical solution. standard measurement method for conductivity time-consuming delicate procedure performed only at cost significant degree uncertainty. Investigating predict in significantly less time with acceptable level accuracy would useful industry. viewed as unconsolidated, heterogeneous (in size distribution) although well-sorted granular packing, different relationships such systems utilized. Such interdependencies account frictional pressure drop caused by proppant particles often neglect surface apparatus. To extend applicability models, combination theoretical model accounts wall those models clear advantages. For reason, new equation had developed establishes relationship between so-called modified particle friction factor. Since correlations usually contain porosity parameter, determining its value under reservoir conditions essential developed. were which proppant-packs are used, providing issues wide range application primary objective study.
