Proposed method

In order to simulate this problem synthetic data was produced using a 3D subsection of the SEAM velocity model. Initially a 2D VSP dataset was simulated using a parallelised, variable-density, two-way modelling CPU code. A VSP survey was chosen since reciprocity can be used to simulate the relevant surface geometries and this would require far fewer shot simulations. A total of 32 shots were simulated. To extend this to 3D modelling a constant density 3D GPU propagation kernel was written, and is in the process of being adapted to simulate a dataset of this size at an acceptable speed
