RINVERT for Windows provides a unique facility for equivalence analysis which permits the user to control the range of equivalence by nominating the accuracy of the field data. The degree of equivalence is indicated by meaningful descriptors: "unique," "minor," "severe," "extreme." RINVERT for Windows also provides an impressive visual display of equivalent models.

RINVERT Equivalence Analysis

Selecting INVERSE allows RINVERT for Windows to find the best models which fit your sounding data. RINVERT for Windows automatically modifies an initial estimate of a layered earth model until the simulated and observed sounding data closely agree. RINVERT for Windows also displays the sounding curve and goodness-of-fit for each iteration.

RINVERT Help System

RINVERT for Windows comes together with a Windows help system providing you with fully comprehensive, context-sensitive help on every menu item or dialog box. With RINVERT's sophisticated help system, your search is only a keystroke away.

RINVERT Forward Modeling (Simulation)

Selecting FORWARD allows RINVERT for Windows to generate the sounding curve for your earth model. RINVERT for Windows also allows the user to change the model repeatedly until the sounding curve matches visually with the field data.

This information may be printed out with tables and graphics, for field data, forward modeling, inverse modeling and equivalence analysis in report-ready format. The report may be checked by a print preview facility and then sent to any Windows-supported output device in full color or black and white. Intelligent default settings combined with intuitive on-screen editing makes customizing your reports a snap. Creating publication-quality reports has never been easier.

RINVERT Report Generator

The user has the opportunity to complete an on-screen form of sounding, location, project and illustration details as well as freeform comments.

Your first chart in RINVERT is displayed by simply selecting a data file and clicking on OK. It's easy! Intelligent default settings allow you to analyze complex data sets without having to go through menu after menu. If you have used Microsoft Windows then you are familiar with many of the commands used in RINVERT for Windows. If not, now is the time to discover the power of Microsoft Windows together with RINVERT for Windows.

RINVERT - A Proven Solution

RINVERT for Windows supersedes RINVERT for DOS, adding even more features at an unbelievable price. It is a natural evolution of an algorithm which has been applied successfully to thousands of resistivity soundings worldwide over the last 20 years. Can you afford to be without it? Save time and increase productivity - RINVERT for Windows provides fast, accurate, 'user friendly' interpretation and dynamic on-screen model display.

Modeling with RINVERT

The following will show simple steps on how to analyze your data, run forward and inverse models, perform equivalence analysis, and generate reports for your resistivity data.

File Types in RINVERT
RINVERT features worksheet-style editors for entering or editing field data and model parameters. RINVERT for Windows uses two basic file types: data (.dat) files and model (.mdl) files. Both file types are stored as ASCII files so that the user can modify them with an external editor if desired. Normally, the user would edit field data and model parameters within RINVERT, and the files would be updated automatically.

A data file may contain more than the list of electrode spacings and apparent resistivities. It is also used to store sounding details, location details, project details, report details and comments. A model file contains a list of layer thicknesses and resistivities for the current model.

Electrode Array Types in RINVERT
An electrode array consists of four electrodes: two current electrodes for injecting current into the earth and two potential electrodes for measuring voltage at ground surface. Although many combinations of four electrodes are possible, a few standard arrays are used in practice.

RINVERT for Windows accommodates the three most popular resistivity electrode array types: Schlumberger Array, Wenner Array, Bipole-Bipole Array. The Schlumberger and Wenner arrays use a linear layout of electrodes. The Bipole-Bipole array, also referred to as the dipole-dipole" array, can have a wide range of orientations, but only the linear (or polar) orientation is supported by RINVERT for Windows.

Using RINVERT for Windows
These are the general steps you follow to analyze your resistivity data.

1. Create a sounding data file which consists of electrode spacings and apparent resistivities. This file can be created in the RINVERT editor window or outside RINVERT using an ASCII editor. A data file is required to provide RINVERT with the field data necessary to infer a model of the earth's resistivity.

2. Choose a model which provides a trial interpretation of the resistivities and thicknesses of the earth's layers.

3. Run the Forward model. RINVERT for Windows will display a graph of the theoretical sounding curve corresponding to the current earth model. The model is represented in bar graph form using resistivity and depth as the axes.

4. Run the Inverse model. RINVERT for Windows will display the theoretical sounding curves corresponding to the initial earth model and each subsequent trial model as convergence proceeds.

5. Run the Equivalence Analysis option. This analysis indicates the range of earth models which match the field data just as the final inverted model.

6. Print the automated report by clicking the printer icon or by selecting the Print Report option from the File Menu.
