13.6.1 Use Case

1. User exports the seismic line structure: topographic line or polyline from Software A ( Figure 13.6.1-1 , Horizon 1).
2. Based on this structure, user also exports seismic picked (potentially tracked as well) horizons by means of polyline defined by X, Y, Z coordinates + seismic 2Dcoordinates ( Figure 13.6.1-1 , Horizon 2).
3. Import those data in Software B.

There are two scenarios of interpretation on a 2D seismic line (which are both explained below):

• 13.6.2 Interpretation from a 2D Line
• 13.6.3 Interpretation of a 2D Extract from a 3D Dataset

Figure 13.6.1-1 A 2D seismic section picked on a 3D seismic block. Two horizons are interpreted on this 2D seismic section.
