More Information
Summary:Methods and computing systems for processing electromagnetic data are disclosed. In one embodiment, a method is disclosed that includes performing a first controlled source electromagnetic survey at a selected area that includes a reservoir zone; performing additional controlled source electromagnetic surveys at the selected area after the first survey; and inverting measurements from the first survey and the additional surveys to identify at least one resistivity change in the reservoir zone after the first survey, wherein during the inversion, respective measured resistivity values from the first survey and respective measured resistivity values from the additional surveys are constrained to be constant, and correspond to one or more areas disposed in the selected area that are outside of the reservoir zone.
