PGS, in collaboration with EGAS, has completed an extensive 3D GeoStreamer data acquisition and imaging campaign in Egypt’s west Mediterranean Sea
They have captured post-stack depth-merge, over 24,000 sq km of data, raw and final KPSDM full-stack volumes in time and depth, migration velocity model in depth, and processing report. These data have now been merged into a single full stack depth seismic volume (KPSDM), including two pre-existing reprocessed overlapping MC3D surveys (legacy 3D data).
The wider area was mapped using 2D seismic data in 2016 and 2018, providing an extensive overview of the regional geology and structure. The new West Egypt 3D Merge allows explorers to gain a far more detailed overview of the plays and structures available. This includes the shelf area, which is an extension of the proven onshore western desert play fairways and is likely to rank highly as a focus area for upcoming exploration activity.
Farther into the basin, there is the potential for shelf-edge structures and carbonate buildups, some of which are sealed by Messinian evaporites. In the deeper water areas, plays relating to pre-Messinian salt structures and pinch-out features against the shelf edge are also likely to be a focus for explorers.
"This merged MC3D volume is an ideal screening product for companies looking to rapidly evaluate the subsurface potential of this frontier area, prior to committing to pre-stack seismic products or entering the area. The PSDM volume is now available for licensing," said Mark Hamilton, PGS principal geoscientist for Africa, Mediterranean and Middle East.
