Fast and reliable 3D EM modeling software that can accurately handle arbitrary anisotropic conductive media with complex structural interfaces and hydrocarbon reservoirs. It makes crucial contribution to the success of EM technologies. 3DEM is addressing the needs of the exploration&production industry in advanced 3DEM modeling products.
3DEM’s core technology is the proprietary 1D-2D-3D EM modeling software that has been rigorously tested and validated. The software can be used virtually for any application of 3D electromagnetics in borehole, on land, or in marine environments and can take into account complex topography, seafloor bathymetry, subsurface geology, and arbitrary 3D anisotropic resistive media. 3DEM best-in-class software is more robust and runs much faster than the competition. The following 3DEM modeling software modules and applications are available for licensing and come with technical support for users and developers as well as software training:
