July 2015 — Focused-Source EM method has been field-tested over Hockley salt dome (Hockley field test site, Harris county, Texas) by KMS Technologies - KJT Enterprises Inc.
June 2014 — U.S. Patent on Focused-Source EM has been issued:
Rykhlinskaya, E. and. Davydycheva, S., 2014, Method for marine geoelectrical exploration with electrical current focusing, U.S. Patent 8,762,062 B2.
November 2013 — 3DEM Holding jointly with SingularEM has successfully completed a 3D marine Controlled-Source Electromagnetic (CSEM) modeling project for EMGS using 3DEM’s proprietary general anisotropy finite-difference modeling software. The scope of the project included generating wide-azimuth, multi-component and multi-frequency electromagnetic data for a synthetic 3D CSEM survey. The survey included: a grid of 252 seabed receivers performing registration of three electrical and three magnetic components at 20 frequencies, 16 towlines, and 574 km of the EM source towing.
August 2013 — 3DEM Holding jointly with SingularEM has successfully completed a large 3D time-domain controlled-source electromagnetic modeling project for Shell. The goal of the project was to study the effects of complex anisotropic 3D subsurface conductivity structures, the terrain and acquisition geometry on the electromagnetic fields acquired during land exploration for hydrocarbons.
