Abstract

Increasing production efficiency and monitoring water/steam/CO2 movements are key issues for hydrocarbon production and geothermal reservoirmonitoring.Similar technical issues exist for CO2 storage applications. They can be addressed with borehole and surface electromagnetic measurements, which are sensitive to fluid variations in the pore space. At the same time linking the electromagnetic (EM)information to 3D surface and borehole seismic data yields extrapolation to the interwell space. Evaluating several reservoir dynamic monitoring methods and technologies leads to a practical concept of Full Field Fluid Monitoring with electromagnetics. Our implementation includes marine and land sources and receivers, surface-to-borehole arrays and single well system that can look tens or even 100 m around the wellbore and ahead of the drill bit
