Herodotus Basin - Egypt

MC3D-EGY20-BLOCK1 3D GeoStreamer

3D GeoStreamer coverage essential for lead and prospect identification.
Website Map for Survey MC3D-EGY20-BLOCK1
3D seismic survey in the very western part of the offshore area following up on regional 2D in order to further assess prospectivity across Egypt's west Mediterranean offshore.
The survey covers the deeper water parts of the Herodotus Basin, beyond the shelf. The survey includes a salt (evaporite) layer and some deformation related to the Mediterranean Ridge. In this area targets are likely to be presalt structures and possibly pinch-outs against the shelf edge.
GeoStreamer acquisition provides broadband data rich in both low and high-frequency information that can be reliably used for structural interpretation and rock property analysis. PSDM products will be available for accurate imaging of subsalt reservoir targets.
