  "id": "MLC-T-OAG-003008",
  "term": "Pushdown",
  "field": "Oil and gas",
  "definition": "An apparent downward displacement of seismic reflection events on a time section, caused by an overlying low-velocity anomaly. This effect makes deeper horizons appear deeper than their true depth. Pushdown is a velocity artifact that requires careful correction during seismic processing and interpretation to avoid misinterpreting subsurface structures.",
