Effect of Erroneous Representation of Location and Orientation of EM Receivers for Monitoring of Submarine Petroleum Reservoirs
MetadataShow full item record
The receivers in electromagnetic monitoring should optimally be placed exactly in the same location during every single acquisition. However, for technological and economical reasons, the receivers are currently brought up to the surface to collect the measured data between each acquisition. This demands repeatedly replacement of the receivers, and uncertainties in the location and the orientation of the receivers will thus arise. In this thesis we will perform an investigation of the sensitivity of the electromagnetic signal with respect to an erroneous representation of the location and orientation of the receivers. This will give an indication of whether solutions with fixed receivers should be used in the future.
