Velocity layering

  "term": "Velocity layering",
  "field": "Oil and gas",
  "definition": "The stratification of subsurface materials into distinct layers, each characterized by a different seismic wave velocity. This vertical variation in velocity is a fundamental property of sedimentary basins and causes seismic waves to reflect and refract at the interfaces between layers. The velocity layering is a primary input for building the background velocity model used in seismic migration and depth conversion.",
