The initial fluctuations for an unstable immiscible flood are calculated using a Darcy-scale Langevin equation. The resulting amplitude is a product of a Darcy-scale dynamic term with a pore scale dispersion term. Flood velocity can minimize initial ffuctuations depending on the importance of capill

N e w Jersey Stability criteria are formulated for displacement of a fluid from an infinite porous medium by a second more dense fluid miscible with the fluid being displaced. Pure displacing fluid is separated from pure displaced fluid by a region of constant thickness in which the two fluids inter
## Porous media can be dissolved by pumping acids through them. The pernreability of the porous material will be raised, and this is used by the petroleum industry to increase the productivity of oil wells. The acid flows preferentiahy into zones of high permeability which are therefore most rapid
