Overview
The Bridge Electromagnetics (EM) plug-in consists of a series of modules for visualization, data QC, EM attribute analysis, EM forward modeling and EM inversion analysis. The 3D EM Forward Modeling module complements the 2.5D forward modeling with more details when doing a detailed prospect evaluation. The technology used in the 3D modeling algorithm is based on technology from the Blueback partner TechnoImaging.
Features
3D EM forward modeling is traditionally a time consuming process, even when having access to large cluster computers. The 3D algorithm now available in Bridge provides a very fast solution through the use of the integral equation formulation of the simulation problem. By constraining the 3D volume to a limited region of interest we have been able to reduce the amount of calculations significantly. This makes the module perfect for reservoir characterization and sensitivity studies where many iterations of the 3D modeling must be done. By combining the 3D forward modeling capabilities with the already existing 1D and 2.5D modeling tools one can also incorporate bathymetry effects and background trends in modeling, which can be of crucial importance in sensitivity and feasibility studies.
