In-Depth's Reverse Time Migration
Reverse Time Migration has established itself as the most rigorous and accurate imaging tool for unraveling complicated geology—especially when involving the structure of evaporites (salt, carbonates, and anhydrites) . In-Depth’s RTM+ handles multi-pathing, two-way, wave based, >90 degree dips, and many other complex imaging scenarios. By contrast, Kirchhoff simply fails to handle these scenarios.
The example shown here is an RTM+ image with only a single swath of input data. The left shows the inline section of the swath and the right shows the map view of the image. RTM+ provides crisp images of the faults, even with a small amount of data.
The most accurate way to analyze image quality is by evaluating the classic impulse response. The impulse response shown here clearly shows that In-Depth’s RTM+ delivers accurate amplitude, phase, and large angles.
