Herodotus/West Egypt Shelf - Egypt - 1999-2007

EGY Reprocessed 2D

Reprocessed legacy 2D data essential for the upcoming license round
Website Map for Survey Egypt Legacy Data 2D
Together, the new and legacy 2D seismic data cover a frontier area of more than 80 000 sq. km.
Pliocene sandstone play potential extends from the Nile Delta with potential for Zohr-type presalt carbonate plays in the Herodotus Basin in addition to the presalt sandstone play. The Shelf area is an extension of the onshore Western Desert Basin with a proven petroleum system and oil play.
Rejuvenation of legacy 2D data through PGS' full integrity broadband processing. Both PSTM and PSDM products are available.
