    摘要： Seismic survey data is converted into a subsurface data volume that users can view to understand and analyze the subsurface structures in the survey region. At least some of the disclosed systems and methods employ three-dimensional reverse time migration using wave equations adapted for use in formations having tilted transverse isotropy. Relative to existing methods, the disclosed systems and methods rely on fewer approximations and suffer fewer limitations on the circumstances in which they can be employed. Moreover, because the disclosed wave equations are derived from Hooke's law (and consequently they operate on fields that are directly tied to physical quantities), they demonstrate an increased stability relative to existing methods. Survey data analysts employing the disclosed systems and methods should obtain better images of the subsurface and be better able to identify reservoirs and deposits for commercial exploitation.

    摘要： 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.
