Geological Aspects of CO2 Storage and Geothermal Energy in the Pau Region: Visit of Rousse CO2 storage facilities and monitoring demos

Friday 4 October: 08:15 hours - 17:45 hours


In the morning, the tour will start with a visit of the Rousse facilities, where over 50 000 tonnes of CO2 were stored from January 2010 until March 2013. The site has now been switched to a post injection surveillance mode.

The visit will consist of three stations

  • Overview of the well head, CO2 compressor and micro-seismic shallow well;
  • Demo on the Sentinelle shallow surveillance well, where soil gases are monitored continuously
  • Demo of the SIGIS2 mobile unit, including an infra-red CO2 teledetection system, performed by a CNRS scientist

Walk to the outcrops of the geological formations

After lunch, in the afternoon, 4x4 buses will be used to reach the nearest ridge summit at an altitude of 1300 m, where outcrops of Mano and Meillon dolomite reservoirs, and their cap rocks, will be revealed. These formations are used for the Rousse CO2 storage, and also considered for geothermal projects around Pau.


Short strolls in meadows with small ridges will allow the observation of reservoir heterogeneities such as sequence boundaries, sedimentary facies, faults and fractures, as well as the clayey seal formation up section. Analogies will be made with corresponding facies and characteristics from cored material. Good hiking shoes are compulsory in such a mountain environment, even though the walks are short, very safe and with no difficulties.


Weather permitting, magnificent views of the Pyrenees foothills and crest lines should unfold and will be explained in their geological context, with the view of the Pau city and the Rousse CO2 storage facility in the plains. Should the weather be incompatible with the hike, cores will be displayed to the participants and put into context through dedicated posters.

In all cases, a brochure will be distributed to all participants.

Health and Safety

All participants will be provided with an HSE guide for this fieldtrip.

- Please note that a 4x4 drive to the outcrops of the Mano and Meillon dolomite reservoirs, and their cap rocks, will be part of the field trip. Part of the roads will be an uneven track and therefore might cause inappropriate conditions for people with health conditions incompatible with vehicle vibrations, i.e. serious back problems.

- Solid footwear is required!

Please contact the EAGE Head office if you have any specific questions regarding health and safety via

In case of bad weather (fog or heavy rain), the 4x4 drive to the outcrops shall have to be cancelled. Instead, an alternative programme with presentations on concepts similar to that of the fieldtrip will be on offer. In case of poor weather conditions that would prevent to go to the outcrops, the minibuses will take the group to a facility in the nearby Gan city. After the picnic, additional material will be presented to explain the geological context of the CO2 geological storage in Rousse:
- field trip leaders will show posters explaining the geological set up, main regional gas reservoirs and their cap rock;
- core material will be displayed to illustrate the posters.

As with every fieldtrip, this field trip is not without risk. We will take every precaution possible, however we advise you to make sure that you are sufficiently insured. All field trip participants shall be required to sign the indemnification form (waiver) prior to the field trip.
