Abstract

Abstract Several on-site studies have been conducted on rock formations and soils where gases were collected into boreholes. The equipment consisted of packers isolating a chamber for gas collection. A pump allows gas transfer towards FT-IR sensors located at the surface. Such analytical approach shows several advantages for gas monitoring in boreholes: it allows variation detection with time of the partial pressure of gases; detection and evolution with time of the concentration of annex gases or markers; application to the injection and post-injection periods to determine possible deviations from a previously recorded baseline; and possible use of several boreholes in networks.
