    Interactive Petrophysics (IP) was developed by a Petrophysicist, with a view to work as petrophysicists want to work, but never thought possible! The software is different by design - portable, quick and versatile. It is an easy to use log analysis tool, ideal for both geoscientists and petrophysicists. Geoscientists may wish to quality check of their log data and experienced Petrophysicists can carry out multi-zone, multi-well petrophysical field analyses.

    IP is truly unique in its approach to petrophysics. For the expert user IP offers some of the most sophisticated interpretation modules in the industry.

    What is IP?

    Interactive PetrophysicsTM has been developed over 12 years and is now used by over 300 companies, in more than 70 countries globally.

    The User Program module is arranged on a set of easy to use input/output screens to allow for the setup of normal IP functionality with interactive plots and displays.

    The heart of IP is its graphical interpretation engine. This allows the user to perform a fast and sophisticated multi-zone interpretation using only the mouse, adjusting parameters on log plots, crossplots and histograms.

    Interactiveinterpretation

    The user clicks on a parameter line and drags it to the new position. IP instantly recalculates the results and updates the graphics.

    Interactive lines allow adjustment of most parameters including, Rw, Rmf, clay parameters, hydrocarbon density. Pickett plots can be used to set Rw amd m.

    Interactive lines can be used to set cut-offs on the log plots as well as crossplots.

    The NMR modules are part of the base IPTM module and allow for the complete integration of NMR data into the petrophysical evaluation.

    NMR Normalisation allows all NMR distributions to be standardised

    Timur/Coates permeability coefficients can be derived from regression with external permeability data when it is available

    NMR Interpretation using the Dual Water volumetric solution utilising NMR and Resistivity data provides a more constrained result and reduces uncertainty

    T1 or T2 data can be calibrated to core Pc data using a one point or two point methodology on either a T2 vs. Pore Radius plot, or, as in the example shown, on Cumulative Porosity vs. Sw plot.

    The Pc curves derived form T1 or T2 distribution can be used to derive a Sw height curve.

    The IP database is simple to work with but also flexible. It can be a single well for a quick look interpretation or a multi-well and multi-field database. An IP database consists of a binary data file (.DAT) for each well, each consisting of log curve data, general well information and interpretation Parameter Sets.

    The Database Browser allows the user to drill down into a well and view or edit individual curves, parameters, log plots, crossplots and histograms, well data, statistics and listings, etc.

    Curve sets give the user the flexibility as the only requirement is that all the curves in a curve set should have the same step.

    Picture curves can be displayed on log plots, for example, a sonic semblance plot can be loaded from a screen grab of a PDS file and a DT pick made with the interactive curve editor.
