BIGS: BTEX Isotopic fractionation for Gas Storage in aquifers monitoringSeed Funding

Groundwater quality management is a major concern when storing natural gas in aquifers. One of the promising indicators concerns the monitoring of the natural bio-attenuation of volatile organic tracers, such as BTEX, by measurements of the isotope ratios of d13C and dD. However, it requires a robust and precise measurement chain and an interpretation framework that is still under debate.

This is what motivated researchers from two laboratories hosted at UPPA, LFCR and IPREM, associated with an industrial partner, Storengy, to elaborate the BIGS project. Its main idea is to quantify the possible fractionation, a priori weak, of d13C and dD of BTEX due to physical mechanisms (solubility and diffusion) in storage conditions.

To achieve this goal, the research program will combine isotope analysis and original experiments, based on natural samples collected under in situ conditions, molecular simulations and thermodynamic modeling. The aim is to verify that isotopic fractionation is above all an indicator of the biodegradation of BTEX.
