Some of the main features are:<br /> <br /> - A standard Windows user interface for data manipulation and display of analysis plots. Full copy and paste facilities are available to exchange data with other programs (e.g. a spreadsheet, word processor, or another copy of PIE).<br /> - Graphical data processing to reduce large sets of raw rate or pressure measurements to a manageable size.<br /> - A complete set of analysis plots ranging from simple Horner and Derivative plots to specialized plots like the &quot;Sand-Face Rate Convolution&quot; plot.<br /> - An extensive set of type-curve models that cover a wide range of well and reservoir systems.<br /> - Non-linear regression to adjust all of the parameters for a type-curve model to obtain the best fit to the analysis data.<br /> - A variety of type-curve analysis methods ranging from simple &quot;draw-down type-curves&quot; to multi-well type-curve simulation. The type-curve simulation includes a variety of production constraints (e.g. compute rates for a fixed flowing pressure).<br /> - Available for Windows 2000/XP/Vista systems.<br /> - PIE is year-2000 compliant";
