5D reconstruction has become a mature technology in the past decade because it is widely used for wide azimuth measurements. This method is called 5D interpolation because it runs on five dimensions of seismic data, a time dimension and four spatial dimensions.The four spatial dimensions are either inline/crossline/inline-offset/crossline-offset, or, inline/crossline/offset/azimuth, and time dimension can be expressed in frequency. Choosing inline-offset and crossline-offset as spatial dimensions leads to a Common Offset Vector (COV) or Offset Vector Tile (OVT) description of the data.

5D reconstruction are by far the most commonly used for interpolation and denoising of seismic data.
