A two-step enhanced oil recovery process in which a surfactant slug is injected into the well followed by a larger slug of water containing a high-molecular-weight polymer which pushes the chemicals through the field and improves mobility and sweep efficiency.  1, record 1, English, - micellar%20flooding

... it would not be economical to use polymer continuously over the entire life of the flood... At some time during the early life of the process, injection of polymer solution must be terminated at some "slug cut-off" point. This polymer slug is then moved through the reservoir by the continued injection of normal brine.  1, record 2, English, - polymer%20slug

Refoulement par l'eau des bouchons miscibles. [...] une limite inférieure du rapport gaz-eau est celle pour laquelle le gaz et l'eau ont des vitesses égales dans le réservoir. Si l'on dépasse cette limite l'eau [...] vient en contact avec le bouchon de solvant et l'on n'a plus affaire à un déplacement miscible, mais à un balayage par l'eau [...]  1, record 3, French, - bouchon%20miscible

A stabilized oil bank will build up ahead of the slug.... this oil bank will flow with a certain mobility. The surfactant slug's mobility should be less than the oil bank mobility. Likewise, for efficient displacement the mobility control polymer should be less mobile than slug and oil banks. Loss of mobility control in the fluid sequence will cause fingering and reduced displacement efficiency.  1, record 5, English, - mobility%20control
