Abstract (en)

[origin: EP1889999A1] The method involves determining a speed and flow direction of a fluid using a flow simulator to solve a pressure equation. A relation describing a position of a front separating the fluids is defined by liberating a viscous coupling using disturbance theory and considering speed fluctuations in forward direction from the front and in direction perpendicular to a forward direction. The position is reconstructed in a grid using relation discretization and rapid Fourier transformation. Injection of a purging medium is optimized according to the position.
