Magnetotelluric exploration for hydrocarbons
Proceedings of the IEEE, 1989The magnetotelluric (MT) method utilizes naturally occurring low-frequency electromagnetic energy to determine the electrical resistivity of the Earth's subsurface. The resistivity distribution of the subsurface is then interpreted in terms of rock type and geologic structure.

MTpy: A Python toolbox for magnetotellurics
Computers & Geosciences, 2014We present the software package MTpy that allows handling, processing, and imaging of magnetotelluric (MT) data sets. Written in Python, the code is open source, containing sub-packages and modules for various tasks within the standard MT data processing and handling scheme.

Directional noise cancelling in magnetotellurics
55th EAEG Meeting, 1993In Magnetotelluric (MT) data processing, poor signal-to-noire ratio usually biaces the impedance tensor Z elements estimates. Strong electromagnetic (EM) noise may thus render the MT method impracticable in industrial areas. Noise due to periodic sources (i.e. power line harmonies) is easily removed by analog filtering in the field; but non-periodic EM

The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics from the salient physics and its mathematical representation, to practical implementation in the field ...

An Interpretive Analysis of Magnetotelluric Data
Exploration Geophysics, 1984Abstract A simple analysis to determine the dimensionality of magnetotelluric resistivity variations, to separate the near-surface resistivity variation from the variations at depth, and to find the relative resistivity variations with depth is described.

Diagrams for magnetotelluric data
Geophysics, 1976Abstract Observed magnetotelluric data are often transformed to the frequency domain and expressed as the relationship [E1E2]=[z11z12z21z22][H1H2] where E1, E2 and H1, H2 represent electric and magnetic components measured along two orthogonal axes (in this paper, for simplicity, to be north and east, respectively).

The magnetotelluric inverse problem
Geophysical Surveys, 1983The magnetotelluric inverse problem is reviewed, addressing the following mathematical questions: (a)Existence of solutions: A satisfactory theory is now available to determine whether or not a given finite collection of response data is consistent with any one-dimensional conductivity profile. (b)Uniqueness: With practical data, consisting of a finite

Auxiliary Tools for Magnetotellurics
2020In this chapter, we shall briefly discuss the geophysical tools that are categorised as auxiliary tools for magnetotellurics where both natural and man-made sources are used to measure both electric and magnetic fields. These tools are: (i) audiofrequency magnetotellurics (AMT), (ii) controlled-source audiofrequency magnetotellurics (CSAMT) and (iii ...
