AB: ProcintLog is a GUI academic software that runs under MATLAB and is useful for simplified conventional oil and gas well logs analysis. It works through two distinct modes: (1) direct petrophysical parameters inclusion from both field copies and digital files and (2) by reading and filling data from visual log zoning. The software load ASCII and LAS format files and identifies the logs available, supplying both a header file with additional information about the well and a matrix that depicts the depth in the first column and the logs in the remain ones. The last can be loaded by ProcintLog and checked out for unusual highly noisy and spurious data, which allows a complete data control. Furthermore, each one of the proposed processing modes fits well to any chosen processing sequence, allowing the log interpreter to direct your own necessities into log analysis. To provide a little of perspective, fundamental well-logging principles are stressed by informative icons that can be searched at any time the interpreter need. Calculations such as invasion-corrected resistivity, shale volume, Archie and Simandoux methods for water saturation computations and three types of water resistivity computations are viable. One complete example is performed on both synthetic and real data and results are checked against visual analysis to show the usefulness, rapidness and accuracy of ProcintLog in performing accurate logs analysis.
