Translations:Picking unconformities/4/en

The seismic image shown in Figure 1 is a 3D prestack time-migrated line from offshore Brazil. The unconformity in this example is most striking in the center of the figure where it is sharply angular, but careful observation in the finest tradition of the one-line interpretation reveals that the unconformity probably extends over the full extent of the line. The primary objective of this tutorial is to illustrate how an interpreter proceeds in picking this unconformity on the entire line.
