A solution for generating a 3D seismic migration volume from a set of 2D (& 3D) seismic lines, developed by TGS.

Our workflow uses an advanced structurally conformable interpolation algorithm to maximize the potential of existing 2D multivintage and 3D data. The first step is to create a unified 2D dataset from existing data by demigrating and then matching amplitude and phase. Dip and coherency attributes are estimated and this information is used to guide the interpolation of a 3D volume, which is then 3D migrated. The volume can be used for regional interpretation and optimization of 3D survey design and positioning.

2Dcubed offers advantages for horizon interpretation:

  • Horizon propagation on the 3D volume is accelerated compared to that on the input 2D data
  • Horizons have fewer gridding artifacts
  • Out-of-plane events are more correctly positioned by the 3D migration
