TGS and EGAS Launch Large-Scale Seismic Reimaging Offshore Egypt

TGS has begun a 34,000-kilometre 2D seismic reimaging project offshore Egypt in partnership with the Egyptian Natural Gas Holding Company. The EGY-2DRE2026 project combines data from multiple existing surveys to create a single regional dataset covering Egypt's offshore basins. Using advanced processing including TGS's proprietary imaging technology, the project aims to improve subsurface imaging beneath the region's complex salt layers, supporting exploration ahead of an anticipated future licensing round in the Eastern Mediterranean.

 

Details of the Project

 

TGS has launched a major seismic reimaging initiative in Egypt. The project covers 34,000 kilometres of 2D seismic data. It is being carried out in partnership with the Egyptian Natural Gas Holding Company. The initiative is known as the EGY-2DRE2026 project. Its aim is to improve subsurface imaging in Egypt's Mediterranean waters.

The project supports Egypt's future exploration ambitions. It is intended to support exploration activity in the country. The work focuses on the offshore basins of the region. This positions the project as a foundation for future exploration. It reflects a coordinated effort between TGS and the national holding company.

 

Combining Existing Datasets

 

The project draws together data from multiple prior surveys. It combines data from TGS's GeoStreamer surveys of 2016, 2018 and 2023. This is supplemented with other available conventional 2D seismic data. Merging these sources creates a single regional dataset. This dataset covers Egypt's offshore basins comprehensively.

This approach maximises the value of existing data. Rather than acquiring entirely new surveys, the project reprocesses existing coverage. Combining multiple surveys produces a more complete regional picture. This is often more cost-effective than fresh acquisition. It also leverages the extensive coverage TGS has built over years.

 

Advanced Processing Technology

 

The merged data will undergo sophisticated processing. It will receive advanced velocity model building. Pre-stack depth migration processing will also be applied. This includes TGS's proprietary DM-eFWI technology. These techniques aim to significantly improve the quality of the imaging.

The processing targets a specific geological challenge. It aims to improve imaging of the Messinian salt intervals. This covers pre-, intra- and post-Messinian sections. The Messinian salt layers have historically complicated imaging in the region. Better imaging beneath them is central to the project's value.

The Imaging Challenge

 

The Egyptian offshore presents particular imaging difficulties. The basin has historically been difficult to image. This is due to its complex Messinian salt section. Salt layers can distort and obscure seismic signals. This makes accurate imaging beneath them challenging.

Overcoming this challenge is a key project objective. Company leadership described giving customers a modern, regionally consistent view. This applies to a basin that has been hard to image. Combining latest imaging technology with existing coverage addresses this. The result should be clearer imaging beneath the difficult salt section.

 

Supporting Exploration Decisions

 

The reprocessed dataset serves a clear exploration purpose. It is intended to provide a consistent basin-wide structural framework. This framework supports prospect identification and maturation. It helps guide exploration investment decisions. This makes the data valuable to operators evaluating the region.

The timing aligns with anticipated licensing activity. The project supports activity ahead of a future licensing round. It covers the offshore Nile Delta and Herodotus Basin. The wider Eastern Mediterranean Basin also falls within its scope. This positions the data to inform bidding in upcoming rounds.

 

Timeline and Funding

 

The project follows a defined delivery schedule. Final products for a priority subset of lines are due in the second quarter of 2027. The full project is expected to complete in the first quarter of 2028. This phased delivery provides early access to priority data. It allows operators to begin evaluation before full completion.

The project relies on industry backing for its funding. It is supported by industry funding. This model allows the cost to be shared among interested parties. It reflects the standard commercial structure for multi-client projects. Industry funding also signals demand for the resulting data.
