Land time-lapse CSEM: Collecting, modeling and inversion of CSEM data for a steam-injected oil field

Geophysical methods are widely used for hydrocarbon exploration and time-lapse measurements. One method that can be applied in place of or in addition to the routinely used seismic method, is the Controlled-Source ElectroMagnetic (CSEM) method. The work described in this thesis explores various aspects to improve the land CSEM method for...

Three-dimensional inversion of inductions logs in real-time

In petroleum production and exploration, having good information about a hydrocarbon reservoir is paramount to successful exploitation. A popular tool is to probe the electric conductivity in a well to obtain direct information of the well surrounding. As wells are nowadays mostly horizontally drilled, this information is becoming more important...
