The ESCORT station, an Equipment for Soil CO2 ORigin Tracking is dedicated to the monitoring of the natural gas exchange between the atmosphere and the soil vadose zone and thus provides the description of the time dependent natural baseline of soil gases. It involves both an equipment and a data treatment software:

  1. ESCORT is continuously recording the soil CO2 flux, the soil gas compositions (CO2, CH4 and O2) at different depths together with relative soil temperatures, water saturations and weather conditions and
  2. ESCORT statistically correlates the measured parameters to give a precise description of the controlling factors of CO2 production and migration within the soil. A baseline model is then defined and may be used as a reference for further monitoring of underground CO2 leakage.

ESCORT is a rugged station able to operate for several months on site, given appropriate electrical power is provided.

The station may be deployed on pilot or industrial sites if required, in order to define soil baseline conditions and leakage monitoring.

The ESCORT station
State of the art, uniqueness, & specific advantages

ESCORT comprises all necessary equipment in a single station for an autonomous, long term CO2 baseline survey. It thus minimizes personnel costs and enhances data representativeness.

As it is, ESCORT is the only all-in-one device allowing for collecting meteorological data (temperature, pressure, wind direction, wind speed, precipitation intensity, precipitations type, irradiance), multiple point ground gas composition (CO2, CH4, O2, H2), soil water saturation, soil temperature and surface CO2 flux, and providing an integrated data flux through wireless connection.

The ESCORT data throughput is handled by a server and stored in SQL database format. Custom visualization and statistical correlation tools are available in order to facilitate interpretations and define baseline conditions.

Scientific Environment

The scientific environment may also provide necessary equipment for mobile soil gas surveys in order to define first order status of the tested site. These include soil gas probes, gas pumping and analysis equipment, mobile flux chamber and portable TDR volumetric water content probe.

Continuous monitoring of soil gas at the test site in Rueil-Malmaison may constitute a good framework for comparing other soil gas monitoring techniques, and/or benchmark different technologies.

The scientific team at IFPEN can also provide technical/scientific support for the development of soil gas monitoring technologies, and/or design of test sites.
