Reservoir Modelling
• What can reduce the flow in the reservoir, well, tubing or pipeline:– Asphaltenes – Salts– Waxes– Gas hydrates– Emulsions+ Corrosion
• Chemical inhibitors
Production Problems
Recovery Processes

Integrated Modelling of Oil Reservoirs• Combining Seismic Inversion and History Matching• New concept: porosity can be determined quickly and accurately
from a rather limited number of properties of the seismic wave field - the so-called seismic attributes - combined with information from nearby oil wells
• Partners– Danish Research Council– DONG Energy– DTU– Covers:
• 1 Post Doc + 2 PhD students
Integrated Modelling of Oil Reservoirs
CHIGP – Chemicals in Gas Processing2003-2012: Statoil, BP, Total, Maersk Oil, Gassco, DONG Energy
Budget = DKK >15 mio
• Modelling and experimental work
• Optimizing the use of chemicals: Glycols, Methanol,
• Limiting the emission of chemicals: Aromatics, CO2and H2S
• Data, parameters, and software
• CAPE-Open Module and Aspen User Model of a new thermodynamic model, CPA
CO2 for EOR in Denmark• The Danish National Advanced Technology
Foundation (Højteknologifonden) is supporting a 3 year project carried out by:– DONG Energy– CERE, DTU Chemical Engineering– CERE, DTU Environmental Engineering– GEO– GEUS
• The objective is to create the basis for a pilot project in a Danish oil reservoir

Perspektiver for CERE1. Fastholde de internationalt stærke positioner…
ikke mindst vedr. kalk og anvendt termodynamik2. Aktivere flere kompetencer på DTU:
Materialer, sensorer, robotter, bioteknologi…
...for at kunne tiltrække mange unge talenter
...og levere dygtige ingeniører til samfundet
…og i sidste ende bidrage til en mere effektiv udnyttelse Danmarks energiressourcer
