Abstract
This paper explores an alternative approach to 3D and 4D seismic modeling based on the PSDM simulator technique introduced by Lecomte et al. (2003), Lecomte (2004), and presented in more detail in Lecomte (2008). The method is both computationally efficient, allowing quick, repeatable, multi-scenario analysis, and allows the integration of illumination constraints from the survey and overburden. The PSDM simulator is a rapid and cost efficient alternative for realistic simulation of seismic data which goes far beyond classic 1D trace modeling and allows comprehensive sensitivity analyses by forward modeling. The technique will be demonstrated on both synthetic models and on real data from the Norne field offshore mid-Norway. This paper will focus on the integration of survey data, overburden properties, rock properties and fluid simulator data into the 3D and 4D seismic modeling schemes, and discuss their impact on the seismic responses.
