CO2 and AICV for Enhanced Oil Recovery (EOR)

One major problem with CO2 injection in oil reservoirs is the breakthrough of CO2 into the oil producer. The aim of this project is to verify that this problem can be solved with the new technology, Autonomous Inflow Control Valve (AICV®).

The AICV has the capability to distinguish between fluids based on fluid properties such as viscosity and density. The AICV can be designed to block CO2 when breakthrough occurs. The valve is also reversible, and will open again when oil is the surrounding fluid. At breakthrough of CO2 the valve closes, and the local drawdown reduces, ensuring that the CO2 stays in the reservoir. This technology solves the problem of CO2 breakthrough. Sweep efficiency increases and the CO2 is securely stored.
