Bridge Electromagnetics

Bridge Electromagnetics is designed for integration of marine Controlled Source EM data, with other subsurface data, utilizing Petrel*, one of the industry’s leading geological and geophysical integration platforms. The launch of Bridge brought long awaited functionality for Controlled Source Electromagnetic (CSEM) data to the standard Petrelwork flow. 

Interpretation of Electromagnetic Data

Interpretation of CSEM data is usually not a straightforward task, and requires proper software tools and robust interpretation methodology. Bridge  provides both - through superior functionality and sophisticated work flows.

Since CSEM is not a standalone tool, integration with seismic and other subsurface data is needed to extract the full value from CSEM data in an exploration work flow. Bridge users benefit from the geological and geophysical integration platform of Petrel.

We argue that combined data- and model driven integrated interpretation is the best approach when interpreting CSEM data. Interpretation of CSEM data should therefore be based on both attribute analysis, forward modeling and inversion.

Bridge Electromagnetics is a plug-in product for Petrel

The Bridge Electromagnetics uses the familiar Petrel user interface and provides functionality to organize, visualize, analyze, model and interpret electromagnetic data. Access to CSEM technology and CSEM data in Petrel enables new and improved work flows. Bridge Electromagnetics brings the CSEM technology out to the masses.

The Bridge EM Interpretation Loop

 Key features in Bridge Electromagnetics

  • Anisotropic plane layer forward modeling 
  • 3D forward modeling using Integral Equation method from TechnoImaging 
  • Interactive survey design tools 
  • Dedicated EM window for display, editing and QC of EM data 
  • Superior functionality for creating multiple EM attributes in various formats 
  • State-of-the-art 2D and 3D visualization of EM data
  • Integration of EM data with seismic and other subsurface data

 

Benefits with Bridge Electromagnetics

  • All data types (seismic, well logs, EM data) on one platform 
  • Allows the user to quickly start interpreting the EM data  
  • Both data- and model driven interpretation approach (Bridge EM Interpretation loop)  
  • EM attributes are essential for obtaining a good understanding of the data before more advanced processing is done, and to guide the update of the subsurface model in forward modeling studies  
  • Supports data (measured and modeled) from several service providers  
  • SEG-Y resistivity sections/volumes from inversion can be imported directly into Bridge

Bridge Modules 

  • Bridge Core - a free Viewer of your EM data. Will get you started visualizing and understanding your EM data and other data in your Petrel project
  •  Bridge EM Data Integrator - create reference data and do normalization. Display and interpret EM attributes by creating cubes and maps of normalized data. Data QC and muting, combined with powerful display options and co-visualization, makes this a powerful tool for interpretation prior to performing EM inversion
  •  Bridge 1D & 2.5D Forward Modeling - model the EM response with 1D and 2.5D modeling algorithms. An excellent tool for interpreting real data or evaluating a potential EM response before acquiring an EM survey
  •  Bridge 3D Forward Modeling - powered by EMVmod of TechnoImaging and is a fast and easy-to-use tool for investigating the EM response from a 3D resistivity model in Petrel
  •  EM Inversion Analysis - provides functionality for quality control and for qualitative and quantitative interpretation of the inversion result
