I013 UK Seismic Exploration Using Optimisation of Conventional and Over Under Source Cable Depths K. Davies* (Chevron Energy Technology Company) & G. Hampson (Chevron Energy Technology Company) SUMMARY EAGE 69 th Conference & Exhibition — London UK 11 - 14 June 2007 Introduction Geophysicists are commonly faced with the challenge of improving low frequency signal without compromising higher frequency signal. Scattering and attenuation in basalt or salt often restricts recordable reflection energy to only a few tens of Hz. However a greater bandwidth may also be recordable and necessary for shallow reservoir targets or shallow velocity model building for depth
