• Seismic reflection data are 2- and 3-D representations of subsurface geology, generated by recording how sound waves generated by a source interact with different rock types and geologic structures (e.g., faults) in the subsurface and are reflected back to the surface, where they are recorded by receivers.

Seismic prospecting
source
seal
res.
Seismic reflection data are the primary tools used to define hydrocarbon traps and basin structure. In addition, they can be used with well log data to identify hydrocarbon source, reservoir, and seal sequences. In some limited cases, seismic data can also be used to identify the presence of hydrocarbons directly (DHI’s).
