An injection site in underground environment with controlled conditions and in situ measurements devices at Catenoy, coupled with advanced laboratory facilities at INERIS to measure gaz-water-rock interaction. 

Brief technical description

The injection site is unique in France and probably in Europe. It is located 50 km North from Paris and comprises:

  • 9 piezometers of 25 m depth, in the chalky aquifer of Paris Basin
  • 4 less deep " piezairs " of 11 m (in the not saturated zone)
  • a technical shed including station dedicated to continuous gas monitoring
  • a meteo station.

The 7 main piezometers are aligned in the flow direction of the aquifer, covering a 60m distance. One is devoted to injection, another is upstream to control the baseline environment, the others are downstream.

CO2 (or any other fluid) can be injected in the chalk aquifer at a depth to be chosen between 13 and 25 m, in order to simulate a leakage from a gas storage that is supposed to be located beneath. Push-pull experiments can also be performed, that consist of re-pumping the water after injection.

In order to study the effects of the injected fluid on the environment, INERIS and partners can use i)in situ monitoring in the saturated and un-saturated zone, ii) adequate gas or water samples and iii) advanced laboratory measurements in the neighboring INERIS site of Verneuil en halatte, dedicated to gas-water-rock interaction.

The laboratory facilities include, among other:


  • High-precision (0.01 mg) magnetic suspended balances to measure the gas adsorption on rock
  • Determination of the isotopic signature of CO2 (d13C) to trace the origin of the gas
  • Batch reactors to perform experiments in underground conditions (P and T°)
  • Calibration benches and sandpits to calibrate gas flux measurement devices.
CATenoy Injection site
Gas LABoratory (CATLAB)
State of the art, uniqueness, & specific advantages

The injection site can be operated at lower cost. The aquifer and its natural flow were thoroughly characterized through previous projects. Other sensors or measuring devices can be installed on the site in the request for a given experiment.

The use of such a site for monitoring for direct CO2 injection and for push-pull experiments is unique in France.

The laboratory includes several advanced facilities and allows to run parallel experiments on 6 different lab stations. The Laboratory measurements are usually performed to characterize processes such as gas production and migration, gas sorption, geochemical processes, effects on water quality in the short term or the longer term.

Scientific Environment

Located 20 km from INERIS, the injection site can easily be operated and monitored.

For most experiments, 1 or 2 days are necessary to prepare the injection (or push-pull).

Besides the in-situ measurement, dedicated samplings and lab measurements can be carried out.
