What is ERTLab?

| << | >> |

ERTLab is the Resistivity/IP inversion software that offers full three-dimensional modeling and inversion. Its numerical core, based on tetrahedral Finite Elements, allows the user to input complex topographic information and to invert data-sets collected using surface, borehole or surface-to-hole array configurations.

ERTLab integrates a numerical core, a visualizer and a sequencer in three distinct environments. The reliable and robust algorithm for 3D resistivity inversion assures accuracy and convergence, even when high levels of noise are present in the data-set. The high-performance graphics environment provides real-time visualization of volumes and sections. The Sequencer provides an easy-to-use tool for the creation of 2D and 3D arrays/schedules of electrical resistivity measurements.

Typical uses include:

  • 3D inversion of field data collected along 2D profiles, three-dimensional surface grids, boreholes, surface-to-hole arrays, or any 2D or 3D four-electrode array.
  • Sequence generation: a practical toolkit permits easy development of 2D and 3D surface or cross-hole sequences.
  • Survey design: the tetrahedral Finite Element 3D forward modeling module may be used to generate simulations over synthetic user-defined resistivity models.
  • Advanced 3D Viewer : using the 3D graphical environment inverse and forward models may be visualized in a variety of ways, including sections, volumes and isosurfaces. These may be spun and re-oriented in real-time. You can add labels, and change color mapping by choosing resistivity/conductivity values or using linear or logarithmic colorbars.
