Reservoir simulation

The Reservoir Geology department performs reservoir simulation in different contexts: description and modelling of dynamic reservoir behaviour of oil and gas accumulations, assessments of geothermal energy productivity and dynamic modelling of geological storage operations of CO2. Simulations are performed within research projects and consultancy contracts.

The Eclipse software (E100 Black oil – and E300 Compositional) licensed by Schlumberger is used in integration with the Petrel software (Schlumberger) for geological modelling and displaying.

The performed reservoir simulation work benefits from close integration with the different geological and engineering disciplines encompassed by GEUS.

Oil & Gas

Reservoir simulation techniques are used to characterise the dynamic behaviour of hydrocarbon accumulations; to determine the equilibrium state and to model the filling history and mechanism. Both the filling history and the equilibrium state are important input parameters for saturation-height modelling to determine in-place volumes of hydrocarbons. Especially in tight chalk fields with high porosity but low permeability, as in the North Sea region, capillary pressure forces strongly governs the fluid and pressure distributions. Further, understanding the overall fluid dynamic state of chalk deposits as reservoir rocks on a regional scale have guided to discovery of new and complex trap configurations, i.e. hydrocarbon can be dynamical trapped.

Research projects are funded by oil companies and different research programmes e.g. the Joint Chalk Research programme (JCR) and more recently the Danish Hydrocarbon Research and Technology Centre (DHRTC).

Consultancy work is performed on the Danish sector as well as the UK and Norwegian sectors. GEUS also serve as advisor for the Danish Energy Authority.

CO2 subsoil storage (CCS)

GEUS participates in the overall European evaluation on possible use of CCS (Carbon dioxide Capture and Sequestration) to mitigate climate changes and to reach the EU CO2 target of 80-95% reduction of emitted CO2 in 2050. Large-scale geological storage of COemissions are to be assessed as a potential technology to help reducing the overall COcontent in the atmosphere.

GEUS have contributed with reservoir simulation studies to various research projects on CO2 storage e.g. CO2SINK, ECCO, SiteChar, CO2CARE, ULTimate. Further GEUS is a partner in the European scientific authority CO2GeoNet and engaged in Nordic research on CCS though the Research Council of Norway.

Reservoir simulation techniques have also been used to study combined use of the subsoil, e.g. synergetic effects in combining geothermal energy production with CCS.
