Geotrack International, in association with CSIRO Division of Petroleum Resources, Sydney, is pleased to announce this new addition to our range of thermal history reconstruction (THR) services. Reliable reconstruction of thermal histories in sedimentary basins is a key aspect of reducing exploration risk, e.g. in defining the timing of hydrocarbon generation in source kitchens and identifying tectonic episodes which may have caused disruption of accumulations. This new technique allows further refinement of Geotrack’s THR methods, providing: • improved resolution of the timing of cooling • independent verification and estimation of maximum paleotemperatures between 50 and 80°C • improved definition of later heating and cooling episodes of lesser magnitude following the main paleo-thermal peak (revealed by AFTA) • discrimination between slow cooling and multiple cooling episodes
