Correcting for near-surface weathering using a model-based move-out method for Foothills Depth Imaging

When seismic data is used to image the subsurface, assumptions and calculations are made about the complex near-surface geology to overcome the geologic uncertainties. A near-surface velocity model is generated to calculate shifts in time that is used to correct for velocity anomalies. This same time shift that was optimized the data in time is not optimized for data in depth.
A new method proposed is to make and apply shifts to the data in depth. This calculation will take into account uncertainties unique to the data in the depth domain. This new shift will be based on near-surface model and the deeper velocities, which in turn will more accurately position the subsurface image.
Thrust Belt Imaging will benefit by having a developed methodology specific to the data in depth that will be scientifically robust, economic to execute, and assist to reduce risk in exploration for natural resources.
