Three international firms bid for Greek offshore seismic surveys

Hellenic Hydrocarbons and Energy Resources Management Company has received three bids for non-exclusive seismic data acquisition offshore Greece.

Key points

  • Three international companies submitted proposals for seismic data acquisition.
  • The tender covers offshore regions in Western and Southern Greece.
  • An evaluation committee will review bids before advising the Ministry of Environment and Energy.

What happened

According to Offshore Energy, three international companies with extensive experience in seismic operations have submitted proposals to acquire and process non-exclusive seismic data. The submission window for the international tender concluded on November 9, following an announcement by the Hellenic Hydrocarbons and Energy Resources Management Company on November 10.

The initiative targets offshore zones in the southern and western parts of Greece. State officials noted that deploying advanced technology for data collection will expand the existing geological database for both licensed and unlicensed maritime tracts.

Aristofanis Stefatos, chief executive of the management company, stated that upgrading the geological database serves as a vital prerequisite for evaluating national hydrocarbon potential and attracting capital. Following the conclusion of the bidding deadline, the regulatory body will establish an evaluation committee to review the proposals. The committee will subsequently deliver its recommendations to the Greek Ministry of Environment and Energy.

Stavros Papastavrou, the country's Minister of Environment and Energy, described the international response as an endorsement of national energy prospects. He added that the planned surveys will provide clearer insights into offshore hydrocarbon reserves while respecting environmental regulations and international law.

Why it matters

For energy investors and policy makers across emerging markets, the advancement of Mediterranean exploration highlights the persistent global demand for robust geological data in de-risking upstream investments. Upstream projects require extensive preliminary surveys before capital commitments can be secured, a principle that applies universally from European basins to African hydrocarbon provinces.

Global energy markets continue to navigate complex supply dynamics, with Brent spot prices recorded at 92.14 US dollars per barrel and WTI at 89.62 US dollars per barrel on November 11, according to United States Energy Information Administration figures. For hydrocarbon-producing economies, sustaining exploratory momentum through advanced seismic acquisition remains critical for long-term resource replacement and revenue stability.
