The presence or absence of H2S in oils and oil reservoirs plays an important role in many oil-related sectors. The Rock-Eval 7 Sulfur and Geoworks software make possible, among other things, to analyze the organic and mineral sulfur of the studied levels and thus to better answer problems around sulfur presence. First the machine itself puts forward a more efficient oxidation cycle that can reach the temperature of 1200°C allowing decomposition of sulfates. The device is also equipped with Geoworks software which is used to acquire and process the signals and then calculate parameters related to different methods proposed according to the type of sample studied. Finally, this software offers a kinetic part (Quik Kinetic) making possible calculation of kinetic distributions on hydrocarbons and sulfur produced during the pyrolysis for each analyzed sample with a single heating ramp. An additional module will allow a more complete kinetic analysis as well as a simplified basin modeling. These technical breakthroughs make it possible to highlight the significant interest of this new device and software in the following sectors: gas shale exploration, in reservoir studies, in the refining sector as well as in the study of soils.
