The Interpretive Software Products (ISP) Production Logging Analysis Tool (PLATO) is an interactive graphical oil and gas Production Logs analysis program which employs ISP's Global Statistical Modeling Technique. With this unique technical approach, a complex Statistical Model of the entire well is generated utilizing as much of the available data from as many of the available tools as the analyst desires. Because the comparison is based on statistical criteria, any amount of data can be used, in contrast to an explicit analytical solution where the analyst selects a restricted number of tools and data points. PLATO automatically determines the flow regime using the Dukler analytical model. An enthalpy balance model allows the use of the temperature log to calculate the flow rates. PLATO's 1, 2 and 3 phase analysis for Production and Injection wells comes with integrated emulation capabilities, allowing for simulation of realistic cases from given production rates. The PLATO architecture has been designed for an easy implementation of new tools and user models. PLATO's GUI enables the analyst to edit and visualize all data and results, both numerically and graphically through tables, graphs, histograms, and cross-plots. The Input/Output utility handles a comprehensive variety of data formats and a complete API plot program with binary database capabilities are also included in the package.. PLATO can also be connected to existing customer and industry databases. Complete comprehensive reports can be automatically generated and the form and content of these reports easily adjusted for format and content. Interactive on-line help is available and a system of wizards can guide the user through each step of the analysis.
