==The workflow==
We begin by envisioning a structural play concept based on the thrust belt play of the U.S. Rocky Mountain area. The following workflow discussion tracks this play concept from inception to drill location through a “normal” structural exploration process, as shown in [[:file:exploring-for-structural-traps_fig20-3.png|Figure 1]].
We begin by envisioning a [[Structural trap system|structural play]] concept based on the [[thrust belt]] play of the U.S. [[Rocky Mountains]] area. The following workflow discussion tracks this play concept from inception to drill location through a “normal” structural exploration process, as shown in [[:file:exploring-for-structural-traps_fig20-3.png|Figure 1]].

The technical tasks we identify are often related to the scale of our observation, from regional to microscopic. [[:file:exploring-for-structural-traps_fig20-4.png|Figure 2]] summarizes where the different techniques and tools described in [[structural interpretation techniques and tools]] can be applied. This sequence of tasks, in varying degrees, applies to any structural play.
The technical tasks we identify are often related to the scale of our observation, from regional to microscopic. [[:file:exploring-for-structural-traps_fig20-4.png|Figure 2]] summarizes where the different techniques and tools described in [[structural interpretation techniques and tools]] can be applied. This sequence of tasks, in varying degrees, applies to any structural play.
We limit or reduce the number of structural techniques applied by the inherent maturity of the basin or play. In general, those techniques involving data and data generation on a large or reconnaissance scale (left half, [[:file:Exploring-for-structural-traps fig20-4.png|Figure 2]]) are most important to perform early in a frontier basin or play. More detailed analyses requiring more detailed data (right half, [[:file:Exploring-for-structural-traps fig20-4.png|Figure 2]]) are appropriate only to more mature basins and development studies/plays.
These are depicted in the table below by a common basin/play maturity classification.
