Find out about the newest method for Marine Hydrocarbon Exploration. In this session we will profile the use of Finite Difference Time Domain (FDTD) technique in combination with Mittet's method and GPUs to produce faster, cheaper, more accurate forward modeling for electromagnetic imaging (Controlled Source Electromagnetic or CSEM). Unlike many frequency domain CSEM techniques this accelerated method does not require simplifying assumptions to reduce the memory and computational burden and has excellent scaling properties (essentially linear) across clusters of GPU accelerated nodes. CSEM is used in the industry to enhance confidence in hydrocarbon reservoir discoveries.
