Bridge Electromagnetics

Bridge Electromagnetics is a product for the Petrel platform, ideal for integration of electromagnetic data (EM) with seismic and other subsurface data.

Bridge Electromagnetics for integration of electromagnetic data with seismic or other subsurface data


Bridge is equipped with 1D, 2.5D and 3D EM forward modeling tools and all data can be seamlessly integrated through a variety of visualization tools.

Through normalization, attribute generation and imported EM inversion results, a deeper understanding of the results can be gained by joint interpretation.


The EM Data Integrator module of Bridge Electromagnetics includes functionality for data QC, muting data for given offsets, traditional displays of magnitude and phase, normalization using a series of references, creation of cubes, sections and maps with normalized magnitude, phase, etc. The standard Petrel visualization techniques apply to these EM data objects, making the integration with other data seamless.


  • Data QC of EM attributes. Use various muting options to deactivate data points so they are not included in the normalization process
  • Create a reference receiver, or set of receivers, to be used in the normalization process
  • Normalize your data set using a series of options and techniques
  • Display normalized attributes in the EM window to detect anomalies
  • Create a cube of the normalized data. Use the co-rendering options in Petrel to visualize together with other data in your Petrel project
  • Create a section (2D EM data) of the normalized data. Use for co-visualization together with your data in the Petrel project
  • Create maps displaying normalized data for a given offset range, and drape it on top of a topographic map like Top Reservoir
  • Create line plots to interpret the normalized attributes from several receivers
  • Export cube/sections/maps using the Petrel standard export format options
