trapped | The fluid phase saturation at which the phase becomes discontinuous and unable to flow. This may be at a saturation greater than the residual saturation due to hysteresis. Also known as immobile saturation. | POSC | epicentre 2.1 | current |
residual | The displaced fluid phase saturation which represents the in-situ saturation when a displacement process utilized reaches its economic limit. | POSC | epicentre 2.1 | current |
irreducible | The fluid phase saturation at which the in-situ saturation cannot be reduced. The saturation corresponding to near-infinite capillary pressure. | POSC | epicentre 2.1 | current |
interstitial | The fluid saturations that are trapped in the interstices of a rock. | POSC | epicentre 2.1 | current |
critical | The fluid phase saturation at which the fluid phase becomes mobile. This may be greater than the trapped saturation. | POSC | epicentre 2.1 | current |
displacement | The displacing fluid phase saturation occuring at the displacement front, such as estimated by Buckley-Leverett for immiscible displacement. | POSC | epicentre 2.1 | current |
initial | The original, in-situ fluid phase saturation. | POSC | epicentre 2.1 | current |
current | The fluid phase saturation existing at the time of description. | POSC | epicentre 2.1 | current |
final | The fluid phase saturation that existed or is expected to exist at the time that all operations are terminated. | POSC | epicentre 2.1 | current |
