Sensitivity of Seismic Interferometry and Conventional Reflection Seismics at a Landfil to Processing and Survey Errors

Understanding how sensitive the seismic method is to errors that can occur during a seismic survey or during the processing of the seismic data is of high importance for any exploration geophysical project. Our aim is to image the subsurface of a landfill, which is typically a heterogeneous system due to the presence of numerous scatterers. Therefore, in our case precision is of very high importance. Because of this, we test and compare the sensitivity of seismic interferometry (SI) and conventional reflection seismics survey (CRSS) to errors produced due to time-lapse surveys, migration-velocity errors and muting. Using numerically modelled data, we show that SI provides better subsurface information than CRSS.
