... Abstract Oil recovery from depleted light oil reservoirs (after a waterflood, with overone-half of the oil still in place) requires a large increase in the drivingfluid capillary number and a decrease in its mobility. These often conflictingrequirements are approached in a number of oil...

... in a typical oil reservoir when it reaches economic limit (i.e. after primary and secondary -- waterflood -- recovery). Many methods - often called "tertiary recovery" -- have been proposed for recovering this "unrecoverable" oil. The class of "chemical methods" is of particular interest, because it largely...

... that the results could be compared. The linear model essentially eliminated sweep effects, so that displacement and mobilization efficiencies could be studied more closely. The oil recovery in the linear model experiments for operations at 2.5 MPa was approximately 50%. The base recovery by a waterflood was about...

..., the Second Wall Creek (WC2). Structural relief of 1,500 feet (457 m) and 33 years of variable tempera- ture waterflooding have likewise caused reservoir temperature variations. Finally, although water- flooding has restored the pressure depleted reservoir to near original conditions, it has caused local...

... This paper deals with the development of an analytical tool to predict recovery under both waterflood and miscible flood environments. The recovery predictions are based on correlations in the literature derived as a function of mobility ratio. These correlations are applied on a pattern by pattern basis...

... flood. Conventional black oil simulation was used to model a statistical representation of the reservoir with adjustments for reservoir continuity, carbon dioxide dissolution in water, and miscible effects. These results indicated an incremental recovery over waterflood of twenty percent of the original...
