I-A-2 General Reprocessing condition
The Dakhla seismic program 2D was shot using a 7200 meter cable. The data was
recorded to 12 seconds with 37.5m shot intervals and covering water depths from
shoreline to approximately 2500 m .The area is covered by about 8.000 Km of 2D
seismic data, with a grid of 10Km/15Km, acquired by Total E&P Maroc in 2002.
The performance of the work required hereunder shall be in all respects in accordance
with the best accepted technical standards of the geophysical profession and the
specifications contained within this document - whichever is stricter.
This Article defines the technical specifications that are believed to be routine and
achievable based on state-of-the-art equipment performance and good operational
data processing methods
