Inverse modeling of HEM data using a new inversion algorithm
Helicopter-borne frequency-domain electromagnetic (HEM) surveys are used extensively for mineral and groundwater exploration and a number of environmental investigations. To have a meaningful interpretation of the measured multi- frequency HEM data, in addition to the resistivity maps which are provided in each frequency or for some particular depth levels, it is a necessity ...

متن کاملGeneralized joint inversion of multimodal geophysical data using Gramian constraints
[1] We introduce a new approach to the joint inversion of multimodal geophysical data using Gramian spaces of model parameters and Gramian constraints, computed as determinants of the corresponding Gram matrices of the multimodal model parameters and/or their attributes. We demonstrate that this new approach is a generalized technique that can be applied to the simultaneous joint inversion of a...
متن کاملGeophysical inversion using petrophysical constraints
Petrophysical information is sometimes available from well logs, laboratory measurements, etc. It has been shown that incorporation of such information into geophysical inversions can greatly improve the recovered models. However, when the known petrophysical information is not applicable throughout the entire region, the application of petrophysical constraints to geophysical inversions could ...
متن کاملFocusing geophysical inversion images
A critical problem in inversion of geophysical data is developing a stable inverse problem solution that can si multaneously resolve complicated geological structures. The traditional way to obtain a stable solution is based on maximum smoothness criteria. This approach, however, provides smoothed unfocused images of real geoelectri cal structures. Recently, a new approach to reconstruc tion...
