Three-dimensional seismic-reflection imaging is not new. The petroleum industry has been utilizing this tool to characterize the complex geometries of the subsurface for nearly two decades. Science ...

Older strata may yield direct hydrocarbon indicators (DHIs) in environments typically thought unlikely to contain them. DHIs are features in seismic reflection data attributed to accumulations of oil ...

The Finnish Reflection Experiment (FIRE) dataset consists of seismic reflection data from 2,104 km of common mid-point (CMP) lines. The four FIRE transects cross-cut several geologically and ...

Seismic reflection profiling is used for making 2-D or 3-D cross-sections of underground structures. The principle behind reflection seismics is the same as with underwater echo-ranging. A typical ...

Midway between the earthquake and opposing seismometer the seismic energy reflects in a circular pattern around the top of the inner core. Image may only be used with appropriate caption and credit.
