What I offer

I propose you 25 years of expertise in the reconstruction of the thermal history through the use of low-T thermochronology of different basin-orogen systems.

Thermal reconstructions can be produced from outcrop or well sample, onshore and offshore. The reconstruction of the thermal history from a reservoir, carbonate or shale levels is usually impossible because they do not host apatite or zircon minerals. However, I can handle this by analysing additional samples and using an approach I developed.

I can produce, compile, look for existing databases for you in order to constrain the:

Paleo-thermal history, or time of residence of basin fill series within the oil (160-60°C) and gas (200-160°C) temperature whatever the lithology is through the use of Fission-Track and U-Th-Sm/He analyses on apatite and/or zircon but also Raman Spectroscopy or Peak Temperature (Beyssac, 2002).
Rates of 1) erosion in the orogen and 2) sedimentation in the basin
Date and quantify: 1) deformation, e.g. fault and fold propagation, differential exhumation but also 2) missing or eroded sedimentary piles.
Illite crystallinity analyses to compare with paleo-thermal reconstructions
Additional geochemical and mineralogical analyses, e.g. Rock Eval and vitrinite reflectance
Absolute dating, i.e. U-Pb analyses on 110 zircons.

Conclusion

We developed a novel approach for Oil and Gas exploration that can be used to reconstruct the thermal history from 200 to 45°C (and up to 310°C). The temperature range is large and encompasses the oil and gas temperature windows. It is also free of lithological restriction, it is flexible - we mean that if the information is obliterated it can always be found somewhere else (Fig. 1).
