SensInv1D

- an inversion and modelling software for 1D geoelectric data under Windows9x/NT-

SensInv1D enables the processing of vertical electrical resistivity and IP soundings.

It is a tool to derive the best fitting layered models from soundings performed in different geometries. The program is based on a mathematical optimization procedure which uses a regularization technique to change a given layered model in such a way that the best fitting between the measured and calculated sounding curves is achieved. During the iteration procedure the root mean square (RMS) error between measured and modeled curve is minimized.

The forward problem is solved by a filter technique.

This version is designed to process curves measured in Schlumberger, Wenner, dipole-dipole or pole-pole geometries.


Here is a selection of some software options:


others features are:

- Import of other data formats
- Extracting sounding curves from 2D data sets
- Colored bar display of models
- Display of borehole and logging data
- Correlation matrix for cross-checking relation between inverted parameters
- Sensitivity display of inverted data





Editing of Input Data

You may edit your data file, change or delete data or move data values interactively to new position.



Model Set Up

Also, you may model arbitrary situations and invert data based on those models or you may caculate models response. A contineous layer option is available, where the user may start with up to 20 layers of fixed (logarithmic) thickness to evaluate a smooth resistivity profile.



Model Display

Modelling display can be made as step function or as color display.



Inversion



Inversion results can be displayed for resistivity and phase data.
