Meteogroup, founded in 1986, is one of the largest European weather organizations (12 offices including Poland), serving the Oil & Gas industry with numerous products & services. Meteogroup is present on all continents addressing the Oil & Gas community (operators, engineering, and seismic) and thus has a perfect understanding of the EO weather data that are critical throughout an oil & gas project life-cycle.

Nansen Environmental and Remote Sensing Center (NERSC)

NERSC, founded in 1987, is a key Norwegian leader that provides oceanography EO and model products to Oil & Gas industry.

Tullow Oil

Tullow Oil kindly supports the team as a consultant.

Funded by the European Space Agency, the aim of the EO4OG project is to determine the current and future needs of the Oil & Gas industry in terms of Earth Observation products and services. The project will unroll in three phases over a 10 month period.

Our selected participants have received a PDF brochure (click here to download) explaining the EO4OG project goals and objectives and providing a brief overview of the survey questions. The survey itself will be carried out over the telephone, to best understand participants’ challenges and requirements.

As the survey forms are completed, we will make the results available online, via the OGEO portal.

This project is driven by the needs of the oil & gas industry with regards to offshore exploration and operations, Health and Safety, sustainable development and national and international regulations. The goal is to determine how Earth Observation products and services can best aid the industry at all phases of the OGP lifecycle. Our consortium will work in close collaboration with the oil & gas industry to identify challenges, provide an inventory and description of existing EO data solutions, analyze the gap between user requirements, available products and current uses, and define expectations in terms of improvement of EO data/services and development of new services. 

Special attention will be paid to the typical phases of an OGP project: Pre-license acquisition, Exploration, Development, Exploitation/Production, and Decommissioning. 

Our geographical areas of interest include: 

  • Angola,
  • South Africa, 
  • Mozambique, 
  • Northern Brazil,
  • Argentina,
  • Caspian Sea.



The OTM assessment of information needs is organised into 6 areas; pre-license phase, exploration phase, development phase, production phase, decommissioning phase, and generic requirements. To access the list in each category, click on the links.

The challenges have also been organised into "challenge trees". To access each challenge tree click on the box in the image below. To see the full challenge tree, open the pdf fileAll challenges are available in a single numerical list on the CLS challenges page.
