摘要：
Slow, immiscible, viscoelastic liquid-liquid displacement in a permeable medium is considered. The necessary and sufficient criteria for stability are that the displacing fluid is denser and less mobile than the displaced one. The instability criteria and critical wavelength are found to be the same as those for ordinary viscous liquid-liquid displacements in permeable media.
