An approximate 3D computational method for real-time computation of induction logging responses

Bensdorp, S. (author), Petersen, S.A. (author), Van den Berg, P.M. (author), Fokkema, J.T. (author)

Over many years, induction logging systems have been used to create well formation logs. The major drawback for the utilization of these tools is the long simulation time for a single forward computation. We proposed an efficient computational method based on a contrast-type of integral-equation formulation, in which we applied an approximation...

Wavefield decomposition based on acoustic reciprocity: Theory and applications to marine acquisition

Van Borselen, R.G. (author), Fokkema, J.T. (author), Van den Berg, P.M. (author)

In marine seismic acquisition, the free surface generates seismic events in our recorded data that are often categorized as noise because these events do not contain independent information about the subsurface geology. Ghost events are considered as such noise because these events are generated when the energy generated by the seismic source,...
