Abstract: Seismic Modeling Using Multiple Seismic Sources. At least some of the illustrative embodiments are methods including: simulating an effect of multiple seismic sources concurrently on a geologic formation, the simulating by: reading data from a seismic source file, wherein the seismic source file describes at least two seismic source types; modeling, by a computer system, the concurrent propagation of acoustic energy from the at least two seismic sources types through the geologic formation; and generating a seismic output file.

Abstract: An example method for tomographic migration velocity analysis may include collecting seismographic traces from a subterranean formation and using an initial velocity model to generate common image gathers and a depth image volume based, at least in part, on the seismographic traces. A structure tensor may be computed with the depth image volume for automated structural dip and azimuth estimation. A semblance may be generated using said plurality of common image gathers and said structure tensor. Image depth residuals may be automatically picked from said semblance. A ray tracing computation may be performed on said initial velocity models using said structure tensor. An updated velocity model may be generated with a tomographic inversion computation, wherein said tomographic inversion computation uses said plurality of image depth residuals and said ray tracing computation.

Abstract: Systems and methods for simulating an effect of multiple seismic sources concurrently on a geologic formation are provided. Data is read from a seismic source file that describes at least two seismic source types. The concurrent propagation of acoustic energy from the at least two seismic sources types through the geologic formation is modeled. A seismic output file is then generated.
