Hunziker, J.W. (author), Slob, E.C. (author), Mulder, W. (author)In marine time-domain controlled-source electromagnetics (CSEM), there are two different acquisition methods: with horizontal sources for fast and simple data acquisition or with vertical sources for minimizing the effects of the airwave. Illustrations of the electric field as a function of space and time for various source antenna orientations,...journal article 2011

El Allouche, N. (author), Drijkoningen, G.G. (author), Versteeg, W. (author), Ghose, R. (author)Seismic waves converted from compressional to shear mode in the shallow subsurface can be useful not only for obtaining shear-wave velocity information but also for improved processing of deeper reflection data. These waves generated at deep seas have been used successfully in hydrocarbon exploration; however, acquisition of good-quality...journal article 2011
