VES and Modelling

For additional information about how VES data should be gathered and some details that need attention. Click here

1B and modelling

Two types of cross-sections are prepared by using the appropriate points and the result of inversion of the data obtained from the survey;

1 – Occam type inversion (thin layers),

1D Occam’s inversion
2 – layered subsurface
result of 1D inversion

The coordinates of the measurement points and the direction of expansion are required for this study.

VES data,

AB / 2       MN (or MN / 2)        Roa
   2                  0.25                            10
   3                  0.25                           10.3

Pseudo 2D sections (and level maps) can be generated from the appropriate data. Click for contact.

2D and modelling

2D inversion of VES data

The data obtained from the survey is inverted by our 2D inversion code.

The coordinates (or distance between points) and the the direction of expansion are required for this work;

VES1   X1 Y1 Z1
VES2  X2 Y2 Z2

Expansions can be in X (NS) direction or Y (EW) or any direction but must overlap (click for detail). VES Data in format of,

AB / 2       MN (or MN / 2)        Roa
2                  0.25                            10
3                  0.25                           10.3

the we can produce 2D section (and level maps from the appropriate data). If there is topography information throughout the profile it is used in the inversion process. Click for contact.

3D modelling


Synthetic VES data is created over the expected model to provide preliminary information to see how much information you will obtain from field work, the effect of environmental geology and some occurrence (lakes, seas, etc.), and to design the survey plan. Click for contact.
