 Simulation and Parameter Estimation in Geophysics  -  A python package for simulation and gradient based parameter estimation in the context of geophysical applications.
 
 The vision is to create a package for finite volume simulation with applications to geophysical imaging and subsurface flow. To enable the understanding of the many different components, this package has the following features:

-        EM: Schenkel and Morrison Casing Model
-        ======================================
-
-        Here we create and run a FDEM forward simulation to calculate the vertical
-        current inside a steel-cased. The model is based on the Schenkel and
-        Morrison Casing Model, and the results are used in a 2016 SEG abstract by
-        Yang et al.
-
-        .. code-block:: text
-
-            Schenkel, C.J., and H.F. Morrison, 1990, Effects of well casing on potential field measurements using downhole current sources: Geophysical prospecting, 38, 663-686.
-
-
-        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
-            - 300m long
-            - radius of 0.1m
-            - thickness of 6e-3m
-
-        Inside the casing, we take the same conductivity as the background.
-
-        We are using an EM code to simulate DC, so we use frequency low enough
-        that the skin depth inside the casing is longer than the casing length (f
-        = 1e-6 Hz). The plot produced is of the current inside the casing.
-
-        These results are shown in the SEG abstract by Yang et al., 2016: 3D DC
-        resistivity modeling of steel casing for reservoir monitoring using
-        equivalent resistor network. The solver used to produce these results and
-        achieve the CPU time of ~30s is Mumps, which was installed using pymatsolver_

-        This example is on figshare: https://dx.doi.org/10.6084/m9.figshare.3126961.v1
