EM: Schenkel and Morrison Casing Model
======================================
we create and run a FDEM forward simulation to calculate the vertical
ent inside a steel-cased. The model is based on the Schenkel and
ison Casing Model, and the results are used in a 2016 SEG abstract by

r: Conductivity 1e-8 S/m, above z = 0
ckground: conductivity 1e-2 S/m, below z = 0

The model consists of:
- Air: Conductivity 1e-8 S/m, above z = 0
- Background: conductivity 1e-2 S/m, below z = 0
- Casing: conductivity 1e6 S/m

- radius of 0.1m
- thickness of 6e-3m
de the casing, we take the same conductivity as the background.
Inside the casing, we take the same conductivity as the background.
re using an EM code to simulate DC, so we use frequency low enough
the skin depth inside the casing is longer than the casing length (f
-6 Hz). The plot produced is of the current inside the casing.
