Abstract
We analyze the development, current challenges and the future opportunities of land-based electromagnetic (EM) techniques for reservoir monitoring. Specific reference is made to technologies connecting the surface and the borehole as the most promising approaches to 3D reservoir characterization and monitoring. A few prominent and recent experiments are providing a common base for the definition of an emerging technology for oil reservoirs as well as for CO2 storage monitoring. The path to the establishment of an effective oil field technology shall pass through engineering and standardization for which the current technical challenges need to be identified. The road ahead includes especially the solution of steel casing and pipe responses, new sensors for permanent reservoir monitoring, fiber optics, high voltage signal transmitters, multi-physics integration approaches, integration with reservoir simulators, use of novel machine learning techniques and the adoption of a multi-physics culture enabling the integration of multiple observations to better describe the reservoir dynamics.
