Uncertainty-based frequency-selected inversion of electromagnetic geophysical data

An article of manufacture comprising at least one non-transitory, tangible storage medium containing instructions that, when executed, cause a computer to:

• compute quantified uncertainties associated with an electromagnetic geophysical data signal;
• select a subset of the frequencies based on the quantified uncertainties;
• and
• invert the electromagnetic geophysical data signal for the subset of the frequencies to determine the earth response.

A computer comprising:

• at least one processor;
• and
• processing software that is executable on the at least one processor to:
• compute quantified uncertainties associated with an electromagnetic geophysical data signal;
• select a subset of the frequencies based on the quantified uncertainties;
• and
• invert the electromagnetic geophysical data signal for the subset of the frequencies to determine the earth response.

A method of geophysical surveying, the method comprising:

• acquiring electromagnetic geophysical data;
• and
• inverting the electromagnetic geophysical data to obtain an earth response by
• computing quantified uncertainties associated with the electromagnetic geophysical data,
• selecting a subset of the frequencies based on the quantified uncertainties, and
• inverting the electromagnetic geophysical data for the subset of the frequencies to determine the earth response.

A method of generating a geophysical data product, the method comprising:

• obtaining electromagnetic geophysical data;
• and
• processing the electromagnetic geophysical data to generate the data product,
• wherein the processing includes inversion of the electromagnetic geophysical data,
• wherein the inversion is performed by computing quantified uncertainties associated with the electromagnetic geophysical data, selecting a subset of the frequencies based on the quantified uncertainties, and inverting the electromagnetic geophysical data for the subset of the frequencies to determine the earth response.
