Examples of geology from seismic diffractions

Seismic diffractions have unique properties compared to reflections beyond potential in getting higher resolution. Through four different cases with different challenges and geological setting, we show the benefit from using diffractions to complement the information in the reflections, providing business critical geological information beyond what is possible with reflection-based imaging alone. Diffractions are found in standard seismic data, but are usually weak compared to reflections. Despite this, one of the examples shows improved detailed imaging of a carbonate reservoir from diffractions beneath several kilometers of salt and suggests such methods have a larger range of applications than what has been believed
