Uncertainty-based frequency-selected inversion of electromagnetic geophysical data

摘要

Disclosed are methods and apparatus using frequency-selected electromagnetic inversion to obtain sub-surface geophysical characteristics. One embodiment relates to a computer-implemented method for inverting an electromagnetic geophysical data signal to obtain an earth response. The method involves computing uncertainties associated with an electromagnetic geophysical data signal and selecting subset of frequencies based on the uncertainties. The electromagnetic geophysical data signal may then be inverted for the subset of the frequencies to determine the earth response. Other embodiments, aspects, and features are also disclosed.
