The Pickett plot has been used for decades as a graphic pattern recognition device in the log analysis of Archie equation parameters and evaluation of potential production zones. The reference axes of the plot are logarithmically scaled resistivity and porosity. Water saturation contours plot as obliquely trending straight lines, with slopes and spacings that are set by Archie equation constants, and intercepts by the formation water resistivity. Although simple in concept, the Pickett plot is increasingly recognized to be an excellent medium for the interpretation and analysis of both simple and complex reservoirs. Spreadsheet database and graphics features allow both rapid interaction and comparative evaluation of multiple interpretations or best case/worst case extremes. These features have been incorporated into the program PFEFFER, developed with the support of the Kansas Technology Enterprise Corporation (KTEC). In addition, multiple wells are also easily handled collectively, so that the program is used to map analysis parameters across hydrocarbon fields. Case studies of petrofacies analysis from a variety of fields are described using PFEFFER applied to data supplied from a variety of fields are described using PFEFFER applied to data supplied by a consortium of twelve energy companies active in Kansas.
