Section 3.2 - Projects

Compositional alterations of the petroleum’s low to highly polar, surface active NSO compounds and their effects on fluid properties during migration and production are investigated in conventional and unconventional petroleum systems.

The CarboPerm project is an interdisciplinary German-Russian cooperation project funded by the German Federal Ministry of Education and Research (BMBF). It gains a more fundamental understanding of the consequences of the climate warming for Siberian Arctic soils.

We examine in detail the organic material of the Yacoraite Formation (Maastrichtian-Danian), the most important host rock in the Salta Rift Basin. We also study the geological evolution of the Salta Basin to understand the burial and temperature history with respect to organic matter maturation and hydrocarbon generation.

Aim of the CEL paleofire project is to better understand the role of fire on past landscape evolution of the central European lowlands (CEL) on different spatio-temporal scales using a multiple fire proxy approach. Paleofire regimes will be linked with interacting driving mechanisms, climate, vegetation and human activity.

This project addresses the enhancement of understanding physicochemical processes as well as their controls and mechanisms involved in generation of oil and gas, its primary migration in and expulsion from organic-rich, fine-grained siliciclastic source rock in petroleum systems located on the Norwegian continental shelf, central North Sea.

The mobility of organic and inorganic compounds from black shales in fluid-rock interactions will be investigated taking into account different environmental conditions.

Free Biomarkers are commonly used as tracers of organic matter type and maturity in sedimentary systems. Covalently bound biomarkers in macromolecules can be used as tracers, but first have to be released intact by hydrogenation

Organic sulfur compounds will be characterised in ultra-high resolution by FT-ICR-MS to improve our understanding about origin and fate of these compounds in sedimentary systems.

Until today it is unknown whether the produced oil on Gotland island is sourced from only one black shale unit. Are there further contributors which may lead to new exploration strategies?

The aim for this study is to reconstruct the timing of petroleum generation, the changing gas/oil ratio (GOR) of the petroleum and its physical properties during maturation. The timing and extent of petroleum generation depends on both the thermal history of the source rock and the reaction kinetics of hydrocarbon generation from kerogen.

PEaCH4 v. 2.0 provides a modelling platform to predict, but also to retrace early diagenetic processes in marine sediments. It is the outcome of the BioMeP – Phase II project.

Natural gas mixtures trapped in mineral-hosted fluid inclusions provide valuable information about the origin, generation and migration of gases in the geological record. A new on-line method for simultaneous measurements of stable carbon and nitrogen isotope ratios of fluid inclusion gases was developed at the GFZ.
