Abstract
We investigate two approaches to the transformation of
CSEM data to a more readily interpretable wave field. The
first describes the CSEM response as a weighted sum of
wave-like Chebyshev polynomials; it requires the inversion
of a matrix. The second describes the diffusion response as
a convolution of the equivalent wavefield with a filter in
log(time) and requires deconvolution. The second appears
to be more robust and gives good results for test data.
