Abstract
An important application of seismic modeling is to optimize the acquisition geometry for PRM. For active PRM, the goal is to find best shot and receiver locations based on kinematic and dynamic illumination mapping. For passive PRM the challenge is reduced to finding best receiver locations based on the different targets that are monitored. Seismic illumination modelling is a powerful tool for optimizing the geometry of the PRM station network in both active and passive analyses to maximize the recorded signal strength and to minimize the areal spread of the stations. Seismic illumination maps offer both accuracy and flexibility to identify the characteristic properties of parameters such as hit density and multi-component amplitude strength for various offset and azimuth combinations. Advanced modelling also offers the possibility to generate synthetic microseismic data that are suitable for processing to investigate detection capability and accuracy in noisy environments.
