holistic approach to inversion of frequency - domain airborne EM data
We have developed a holistic method for simultaneously calibrating, processing, and inverting frequency-domain airborne electromagnetic data. A spline-based, 3D, layered conductivity model covering the complete survey area was recovered through inversion of the entire raw airborne data set and available independent conductivity and interface-depth data. The holistic inversion formulation includ...
متن کاملElastic frequency-domain finite-difference contrast source inversion method
In this work, we extend the finite-difference contrast source inversion (FDCSI) method to the frequency-domain elastic wave equations, where the parameters describing the subsurface structure are simultaneously reconstructed. The FD-CSI method is an iterative nonlinear inversion method, which exhibits several strengths. First, the finite-difference operator only relies on the background media a...
متن کامل3D Frequency-Domain Seismic Inversion with Controlled Sloppiness
Seismic waveform inversion aims at obtaining detailed estimates of subsurface medium parameters, such as the spatial distribution of soundspeed, from multi-experiment seismic data. A formulation of this inverse problem in the frequency-domain leads to an optimization problem constrained by a Helmholtz equation with many right-hand-sides. Application of this technique to industry-scale problem f...
متن کاملimproving the results of singular value decomposition inversion using direct transformation of frequency-domain hem data
helicopter-borne electromagnetic (hem) is a fast and high resolution airborne electromagnetic (aem) method that is frequently used for imaging of the subsurface resistivity structures. this is a versatile and cost effective method, frequently has used in mineral and groundwater exploration and various environmental problems. modern frequency-domain hem systems utilize small electromagnetic, mag...
متن کاملrecovering 1d conductivity from aem data using occam inversion
over the past three decades helicopter-borne electromagnetic (hem) measurements have been used to reveal the resistivity distribution of the earth's subsurface for a variety of applications. hem systems include a “bird” or sensor containing one or more pairs of transmitting and receiving coils. the separation between the rigidly mounted transmitting and receiving coils of a coil-pair typic...
