Esys escript in geophysical resistivity application

Asked by febru

Hi Everyone,

My name is Febru, I am just trying escript as an alternative to res2dinv program in application for geophysical resistivity problems. There are some questions that I want to ask.

1. In inversion cookbook, there's a part that explain about the dc resistivity inversion in 3D, but the script is about forward modelling. Is anybody has the tutorial for dc resistivity inversion in escript?

2. If I want to explore the code for forward modeling (i.e for schlumberger survey), which directory that contains the code (modelling class: SchlumbergerSurvey)?

3. Is there anybody who already tried to apply escript in geophysical resistivity application? I want to ask some guide if may

Thank you very much for the attention,

Best Regards,

Feb

Hi Febru,

Here are some answers to your questions.

1. In inversion cookbook, there's a part that explain about the dc resistivity inversion in 3D, but the script is about forward modeling. Is anybody has the tutorial for dc resistivity inversion in escript?

    While Escript will shortly have 3d inversion capability we are still testing this to make sure it is performing correctly. As such it is not yet in the cookbook.

2. If I want to explore the code for forward modeling (i.e for schlumberger survey), which directory that contains the code (modelling class: SchlumbergerSurvey)?

    You can find the SchlumbergerSurvey under downunder/py_src/dcresistivityforwardmodeling.py
    There is also an example available under doc/examples/inversion/dc_forward.py

3. Is there anybody who already tried to apply escript in geophysical resistivity application? I want to ask some guide if may

    We have done some geophysical resistivity work with Escript and plan be publishing papers on this work soon.

Thank you for expressing your interest in Escripts resistivity inversion capabilities and we will notify you when it is ready for use.

Regards,
Jaco.
