Modelling the Effect of Navigation Challenges and Positioning Error in Very High Resolution 3D Seismic Surveying

Based on sensors that emit and record seismic data in the range 1kHz to 20kHz, we describe a method for numerically modelling both the seismic response of a given 3D marine acquisition geometry and the superimposed effects of positioning error and challenged navigability. We develop the idea further to define acceptable limits for errors in positioning and deviation from idealized acquisition layouts. Ultimately,as a result of this form of analysis, we should be able to attain better velocity estimates and 3D high-resolution near-surface images.
