Patent ID: 7979211

Claim:
A method for processing data from a controlled-source electromagnetic survey of a subsurface region, comprising: (a) selecting a data gather from the survey data; (b) reading the selected gather of data into a computer's memory; (c) partitioning the selected data gather into time bins, and transforming the data, bin-by-bin, to the temporal frequency domain, using a spectral decomposition software program, called the spectral decomposition tool, installed on the computer; (d) writing the frequency domain data for the selected gather in a pre-selected internal data format to a data storage device; (e) selecting a frequency component of the transformed data; (f) selecting a data processing or manipulation tool, called the second tool, from among a plurality of such tools that are installed on the computer and applying the second tool to the selected data component, wherein all of said plurality of such tools are adapted to read input data and write output data in said preselected internal data format, and wherein selection and execution of the second tool is made interactively by a user of the method on a graphical user interface; and (g) writing the output of the second tool in said pre-selected internal data format to a data storage device.
