Tuning effect

  "id": "MLC-T-OAG-003952",
  "term": "Tuning effect",
  "field": "Oil and gas",
  "definition": "The phenomenon where the apparent thickness of a thin bed, as observed on a seismic section, is distorted due to the interference of seismic reflections from its top and bottom boundaries. This occurs when the bed thickness is less than approximately one-quarter of the dominant seismic wavelength. Tuning can lead to amplitude anomalies that are not directly proportional to bed thickness.",
