CELL BACED METHOD IN RES2DINV 64 BIT
CELL BACED METHOD IN RES2DINV SOFTWARE

Two ways for induced polarization inversion.Measurements at the water surface and the water bottom.The possibility to work with different (number of electrodes) arrays on the same site. Support any electrodes arrays or combinations with arbitrary system of spacings and electrodes positions.

CELL BACED METHOD IN RES2DINV 64 BIT

Both 32 and 64 bit versions are available.

There is also possibility to import and display results of measurements by other methods and logging and boreholes data that improved quality of results. The robust schemas of noise estimation are realized in the software. In ZondRes2d there is possibility of weights setting for measurements, fixing and limits making of changing features of different cells, using of a priori model as reference in inversion. Because of equivalence of inverse geophysical problems, quality of the obtained results strongly depends on the amount of a priori data used. While program was designed special consideration given to a priori data accounting. ZondRes2d has great range of tools for mathematical modeling and analysis of DC (direct current) and induced polarization fields.Īs the general task of the program is inversion of geoelectric parameters, some variants of inverse problem decision are realized in ZondRes2d, basic of them are: smoothing inversion – to get smooth model and focusing – to get piece-smoothed model of geoelectric parameters with depth. Modeling gives a chance to estimate the level of signal and to make a choice of optimum parameters of the observation system for decision of formulated geological problem. Important stage which precede field measurement is mathematical modeling of geoelectric structure of work site. It’s also support most popular formats AGI, ABEM, MAE-instruments, ARES, Zonge, Res2dInv, Syscal, Sens2dInv.

CELL BACED METHOD IN RES2DINV SOFTWARE

The software works with any (applied in electroprospecting) types of electrodes arrays (two, three and four – electrodes) or their combinations. ZondRes2d uses simple and clear data format which allows easily combining various systems of observation, including different variants of the topography setting up and other additional information. Convenient interface and variety of data visualization features allow to solve wide range of geological problems with maximum effectiveness. ZondRes2d represents ready solution for resistivity and IP imaging, and solves wide range of problems from mathematical modeling and sensitivity analysis to quality control, field data processing and 2D inversion. Special instruments with programmed automatic switching of electrodes is applied for reaching of maximum effectiveness of field works.

Their number usually reaches first thousand that is why the question of field measurements efficiency has basic importance and in many aspects defines possibility of practical using of this method. Resolution and thus results quality of electrical tomography is closely connected with the number and density of measurements on the site. It significantly extends the range of electric prospecting solved problems due to sections investigating that are considerably different from «classic» horizontal-layered.

For interpretation(inversion) of electrical tomography data is used two- and three-dimensional models. Such approach allows from one hand to work with a modern high-performance instruments, and on the other hand, to apply effective algorithms of modeling and inversion of resistivity and IP data.

Its feature is multiple reusing as a source and receiver just the same electrodes position, fixed on a profile line. Zondres2d program is designed for two-dimensional interpretation of electrical tomography data by resistivity and induced polarization method in land, cross-borehole and water cases.Įlectrical tomography ( Resistivity imaging) is technique including both the method of field observations and technology of processing and field resistivity and IP data interpretation.
