Abstract
The Development Leases operated by Shell Egypt in the Abu El-Gharadig Basin are covered by six 3D seismic, cross-spread, orthogonal seismic surveys acquired during the period from 2002 to 2008. The acquisition parameters for those surveys generated low to medium fold datasets with critical geophysical limitations impacting the overall data quality.
All of these seismic surveys were processed using a basic shot processing and Pre-stack Time Migration (PSTM) workflows at the time of acquisition.
In order to maximize the value of these legacy surveys a mega in-house re-processing project was kicked off to re-process the six seismic datasets covering all of the development leases in the basin. The objective of the re-processing was to deploy the latest processing technology on these surveys with acquisition limitations.
