Objective
Future hydrocarbon availability will depend strongly on our ability to effectively produce from subsurface hydrocarbon reservoirs. Multicomponent seismic data acquisition will play a critical role in the future of reservoir management due to its ability to detect small changes in fluid content and stress in reservoirs over time. However one of the key problems limiting multicomponent data quality is the decorative effect of the near-surface on the deeper reflected wave field. Low velocities combined with strong lateral variation lead to extremely large travertine variations in the deeper reflected wave field. In addition high attenuation and scattering due to strong near-surface heterogeneity impacts amplitudes and recorded waveforms. The research proposed will develop methods to investigate and correct for the decorative effects the near-surface has on deeper reflected data based on the receiver function method from earthquake seismology. The research can be divided into three main parts :
(I) Reflectivity and finite-difference modelling of near-surface wave propagation and application of wave field separation techniques to identify the signal observed in recently obtained seismic receiver functions.
(II) Extending the receiver function theory from the seismological to the exploration seismic setting. This addresses the effects of non-planar wave fields in seismic as well as shallow mode conversion on reflection opposed to conversion on transmission.
(III) Application of the extended receiver function methodology to correct for the decorative effects of the near-surface. This includes a shear-wave static's correction and inverse Q-filtering of the data.
