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 ...

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 ...

Figure 1: Three-dimensional seismic survey area and images of melt sills. Using 3D MCS reflection data processed in a new manner to highlight deeper structure, we observed Moho reflections beneath the ...

Integration of conventional seismic data with nonlinear seismic data can provide the industry with new opportunities to better map in situ reservoir properties. This approach will directly affect the ...

The combination of new 3D data acquisition, reprocessing of legacy surveys and faster permitting is offering clearer ...

Geophysics is the application of the methods and techniques of physics in the study of the Earth. It differs from Geology in that a geologist studies rocks and structures, which can be seen, while a ...
