In general, Least-Squares Migration (LSM) can produce images corrected for overburden effects, variations in illumination, and incomplete acquisition geometry. The modeling engine of our LSM...
The challenging combination of shallow water and shallow exploration targets in larger parts of the Barents Sea cannot be sufficiently addressed by the application of conventional marine seismic...
The current drive within the industry is towards a Full Bandwidth solution for seismic imaging coupled with acquisition solutions such as Multi-Azimuth, Wide-Azimuth and Full-Azimuth. Additionally,...
Multiple reflections, which have long been considered as noise in marine seismic, can now be used to image the subsurface. The enhanced illumination they provide, especially for the near-surface,...
In recent years, marine controlled source electromagnetics (CSEM) has found increasing use in hydrocarbon exploration due to its ability to detect thin resistive zones beneath the seafloor. It is the...
