Shell Discovers Crude Oil in Egypt's Deepest-Ever Mediterranean Well

Shell has announced a significant offshore oil discovery in Egypt’s North Cleopatra block after drilling the deepest well ever completed in the Mediterranean. The Velox-1X exploration well reached a depth of approximately 6,500 metres below sea level, confirming the presence of crude oil in the largely unexplored Herodotus Basin.

The discovery marks the first confirmed crude oil find in the basin, although technical studies are still underway to determine whether the resource can be developed commercially. No estimate of recoverable reserves or production timeline has been released. Drilling began in May and was completed ten days ahead of schedule. According to industry reports, the North Cleopatra concession covers more than 3,400 square kilometres offshore Egypt.

Consortium Structure

Shell operates the North Cleopatra block with a 36% stake, following the sale of a 27% interest to QatarEnergy in 2025. Chevron also holds a 27% interest, while Egypt’s state-owned Tharwa Petroleum owns the remaining 10%. QatarEnergy is finalising the administrative processes required to complete its participation in the consortium.

Egyptian authorities described the discovery as an important milestone in evaluating the hydrocarbon potential of the Herodotus Basin, one of the Mediterranean’s least explored offshore regions.

Potential Boost for Egypt’s Energy Sector

The discovery comes as Egypt seeks to strengthen domestic oil and gas production after becoming increasingly reliant on imported energy. Declining output from the giant Zohr gas field has forced the country to increase liquefied natural gas imports in recent years, placing additional pressure on government finances.

A commercially viable discovery at North Cleopatra could help improve Egypt’s long-term energy security by reducing dependence on imported hydrocarbons. However, the commercial potential of the find will depend on further geological analysis, appraisal drilling and economic assessments.

The Velox-1X well is only the fifth exploration well drilled in the Herodotus Basin, making it one of the least explored offshore petroleum provinces in the Mediterranean. Industry estimates suggest the basin could contain substantial hydrocarbon resources, although these remain largely unproven.

Shell has not indicated when appraisal work will begin or when a final investment decision could be made. For now, the discovery represents an important exploration milestone, but its contribution to Egypt’s future oil production will depend on the outcome of ongoing technical evaluations.
