Collaboration between 7 Univ. in France, UK, USA, Canada and Norway and 5 oil companies emphasize research on Integrated EOR in fractured and heterogeneous reservoirs. Complementary high spatial resolution MRI and nuclear tracer imaging in-situ fluid satu ration techniques are used in fractured reservoir blocks and plugs at various scales and at different wettabilities to determine the most efficient oil displacement mechanisms. A larger pressure vessel taking 1ft long blocks at supercritical conditions fo r CO2 floods is constructed. Numerical simulations will be performed using ECLIPSE and Sendra as well as pore scale modelling. The project has obtained industry support from 5 oil companies for 2009-2013; 4 Norwegian candidates for the proposed PhD and po st doc positions are available. Last year we graduated 11 students, 5 PhDs and 6 MS; with 64% being female students. This semester 11 new Master students, all Norwegians, are all ready to start working on this project emphasizing the following EOR techniq ues applied individually or combined for an integrated approach:
- CO2 floods at miscible and immiscible conditions
- Mobility control using foam and polymer gels to reduce fracture permeabilities
- Cost savings by injecting surfactants for fracture surfa ce wettability alteration amounting to injection of only 1%PV; promotes wetting phase bridges across fractures and thus provide differential pressure gradients for the wetting phase in subsequent chase fluid injections; using water or CO2.
- Numerical si mulators and pore scale modelling will be used to match the in-situ fluid movements.
- IEOR-strategy: Apply only 1%PV surfactant pre-flush in moderately oil-wet rock to alter the fracture surface wettability conditions to preferable water wet to obtain w etting phase bridges, then subsequently injecting foam or polymer as fracture permeability reduction agent, with the objective to divert the subsequent waterfloods and/or CO2 floods into the matrix blocks
