LogIC is a complete analysis, display and petrophysical database system for professional geologists, petrophysicists and engineers. Easy to learn and quick to use, LogIC nevertheless offers comprehensive functionality to cover the most taxing reservoir problems.
Analysis is done on a zone-by-zone basis. You may define any number of zones in a single well. Each zone can be assigned different analysis parameters, providing the facility to process geologically complex sequences in one go. Each data level can be analysed by several methods in a single pass. Assigning different equations and methods offers the flexibility to compare and contrast interpretations with minimum effort. For example, LogIC is ideal for developing moving T2 cutoffs for improved Sw interpretation, and also for customising equations for better permeability predictions.A basic philosophy of LogIC is that all the parameters, methods and plot definitions used by the program are stored in “object oriented” parameter files. This approach has a number of useful applications:
Parameter files are associated with a well. Specifying the well means that the data set, analyses and presentations are fully defined. When a new well is drilled, methods and plot formats used on a nearby or analogous well can be quickly and effortlessly loaded for first pass analysis. In many cases the new data can be processed in minutes.
Instead of simply storing the analytical results, LogIC retains, in the parameter files, the means by which those results are obtained. This approach makes it easy to track the processing strategy used for the well.
All standard, and many esoteric analytical methods for clay content, porosity and water saturation are available on LogIC. A multi-mineral option provides a complex mineralogy analysis using the matrix inversion method.
In addition to the standard analysis methods, users can customise existing equations, or add new ones, using the “command interpreter”. The command interpreter operates both in addition to, and independently of, the normal analysis. It includes standard mathematical functions, conditional processing (IF statements) and access to many of the normal analysis procedures. In practice, the command interpreter allows users to perform virtually any analysis or data manipulation conceivable.
Analytical results are presented as continuous curves of porosity, water saturation, and other information.
LogIC furnishes zone-by-zone summaries of net-pay, net-to-gross ratio, hydrocarbon pore volume, as well as averaged channel data over the entire zone, or over the net-sand and net-pay intervals. The zone summaries can be viewed on screen, printed as hardcopy, or made an integral part of log-plot presentation.
