- W2076804028 abstract "Multi-offset VSP and surface seismic data from the Rocky Mountain Foothills of southern Alberta, Canada, has been used to obtain the anisotropy parameters and develop a robust depth-velocity model for the anisotropic depth migration of both data sets. The higherresolution VSP migrated section was spliced into the surface seismic result, yielding an enhanced depth image at the target level. The section was then interpreted to build a 2-D structural model. Numerical VSP and surface seismic data were computed over the model to test a new, prestack depth migration algorithm for the integrated depth imaging of VSP and surface seismic data. This algorithm, which is Kirchhoff-based, uses a common velocity model to migrate the two data sets to a single output grid, eliminating the need for splicing the VSP section into the surface seismic image. Results from the depth migration of the numerical data show that the resulting integrated image yields a result that is superior to those obtained from the migration of either data set alone. There is enhanced resolution at the target level due to the higher bandwidth of the VSP data and also increased structural detail, as the events from both data sets complement each other when integrated. This method may prove especially useful now that simultaneous recording of VSP and surface seismic is becoming more popular." @default.
