Investigation on law of oil production by spontaneous imbibition and water flooding in ultra-low permeability sandstone reservoirs

open access: yesYouqi dizhi yu caishoulu
Pressure drive-based water injection technology has solved the problem of “no injection and no production” in ultra-low permeability sandstone reservoirs in Shengli Oilfield, but the law of oil-water displacement and the percentage of oil production in ...

A mathematical model for spontaneous imbibition as a recovery mechanism [PDF]

open access: yes, 2014
Spontaneous imbibition is a process where the wetting fluid displaces the non-wetting fluid in a porous medium by means of capillary forces. Spontaneous imbibition plays a significant role in the recovery of hydrocarbons, especially from fractured ...
