IRIS’ Enhanced Oil Recovery R&D efforts were launched more than 25 years ago, in close cooperation with both universities and oil companies.
The research is carried out at pore-, core- and reservoir-scales and includes both experimental and modeling approaches.
IRIS’ laboratory facilities provide high quality measurements at desired conditions, including reservoir ones under high pressure and temperature conditions, and using live reservoir fluids.
Laboratory results are modeled using both in-house software prototypes and commercial models/simulators aiming to identify mechanisms contributing to improved oil recovery.
Our experience and knowledge are important when we assist the oil companies in performing field pilots.
Important EOR R&D areas for IRIS include:
Macroscopic reservoir sweep efficiency – Use of water diverting agents (polymers, gels, silicate) to improve macroscopic sweep efficiency and manage water production, use of foam to improve hydrocarbon gas- or CO2 – injection performance.
Rock/fluid and geo-mechanical properties in carbonate rocks.
Microscopic sweep efficiency – Technical Potential, recovery and transport mechanisms of surfactants-, low salinity-, and CO2-flooding; reduction of capillary forces; phase behavior; core floods and modeling.
Pore scale mechanisms – Modeling of fluids distribution, and impact of formation wettability and capillary pressure on oil recovery.
