The inert radioactive gas radon-222, ubiquitous in the environment, is the first cause of lung
cancer in non-smokers and a powerful asset to trace geological fluids and constrain …

Natural analogs offer a valuable opportunity to investigate the long-term impacts associated
with the potential leakage in geological storage of CO 2. Degassing of CO 2 and radon …

Several recent studies have raised the exciting possibility that oils can be dated using the
Re–Os radioisotope system. However the exact nature of the events dated by this technique …

Natural analogue studies have received much interest over past years through the CO2
capture and storage applications. In this paper we focus on one natural analogue in leakage …

(57) ABSTRACT A method is disclosed for determining a presence, type, quality and/or
volume of a subsurface hydrocarbon accumulation from a sample related thereto. The …

A rapid method for local-scale radon risk assessment using in situ radon soil-gas
measurements and a national-scale soil permeability data set have been evaluated. We test …

Prior to the CO 2 injection in the Rousse pilot operated by TOTAL Exploration Production
France, baseline monitoring has been performed in near surface environments in order to …

Soil gas monitoring techniques (CO 2, O 2, 222 Rn, 4 He) are used in the geographical
context of the recent volcanic system of Lake Pavin (Puy-de-Dôme), to get a better …

Four different techniques for measuring radon activity in soil gases were analyzed in the
natural analogue of Campo de Calatrava, Spain, to study its application in superficial …

The south east basin of France shelters deep CO2 reservoirs often studied with the aim of
better constraining geological CO2 storage operations. Here we present new soil gas data …
