In the steady-state method, saturation is quite insensitive to variation of fractional flow of phases due to the severe mobility contrast between the injected phase and the displaced phase. The Displacement method works fine for the imbibition process where high-mobility water displaces low-mobility heavy oil; however, it does not work for the drainage process where the displacement is almost piston-like, hence the information on fractional flow obtained is limited to a very narrow high oil saturation range and is not useful.The new method consists of two test stages. First, to determine the imbibition relative permeability using the displacement method. Second, to undertake a push-pull displacement test to determine the drainage relative permeability. The first portion of the push-pull test is a repetition of the imbibition test to the point of breakthrough. Having known the imbibition relative permeability, one can determine the saturation profile in the sample core at the end of the imbibition process. At the expected breakthrough point, the flow is reversed by oil injection from the original producing end of the core. The well-distributed saturation profile at the start of the drainage process provides information on the fractional flow in a wide range of saturation. History of production of water and oil from the original injection end and pressure drop across the core determines the drainage relative permeability.The method was applied to preserved cores from the Clear Water formation of the Cold Lake oil-sand reservoir as well as to silica-sand packs. The tests were performed using cleaned Cold-Lake bitumen and simulated formation brine at a temperature range from 100 C to 180 C which represent stages in the cyclic steam stimulation process in Cold Lake. The test results exhibited little evidence of relative permeability hysteresis.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
