ZondTEM1D software is designed for one-dimension multi-stations interpretation of Transient ElectroMagnetic (TEM) sounding for various observation systems [Line/Loop, Loop/Loop, Loop/Line, Line/Line).
Comfortable interface and wide possibilities of data presentation allow to solve given geological problem with maximum effectiveness. While developing software special attention was payed to comfort and simplicity of its use, variety of visualization features and account of a priori data.
Depending on the interpreter’s choice, software gives different variants of data interpretation algorithms. Comfortable control system allows to choose from the great number of equivalents results that will appear to be the best in geophysical and geological point of view.
ZondTEM1D allows to work with any types of TEM acquisition systems or their combinations. The program supports as traditional systems (coincident loops, in loop, fixed loops, line-loop, loop-line, line-line), and the most exotic with arbitrary orientation. The geometry of sources and receivers can be various on the plane. Electromagnetic fields and/or their time’s derivatives can be used.
As the basic task of the program is inversion of geoelectric section parameters – few variants of inverse problem are realized inZondTEM1D, basic of them are: smoothed inversion – to get smooth, and focusing – to get the piece-smooth distributing of geoelectric parameters vs depth.
Because of equivalence of inverse geophysical problems, quality of the obtained results strongly depends on the amount of used a priori data. In ZondTEM1d there is possibility of weight setting(Error gates) for measurements, fixing and limiting of different layers parameters, using of a priori model as reference in inversion. If the values of some section parameters are known exactly (a priori or on interpretation results), their fixing is possible before the beginning of automatic interpretation. The fixed parameters do not change during the process of inversion. Fixing of parameters is the method for hard regularization of inversion process. The robust schemas of noise estimation are realized in the program.
