Paper presented at the Annual Technical Meeting, June 6–8, 1995
Paper Number: PETSOC-95-79
... 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...

... left unrecovered 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...

... waterflood was about 40%, hence the incremental recovery due to the WAG process was approximately 10%. The recovery in the two-dimensional model experiments ranged from 40 to 50%. Recovery mechanisms were analyzed by evaluating the relative contributions of WAG, the driving water flood and the blowdown...

... discussed. Displacement tests with spontaneously emulsifying systems showed that residual oil left behind a conventional waterflood was mobilized in a range of capillary numbers much less than that which applies to low-tension waterfloods. Introduction The improvement of oil recovery from a reservoir...

... Abstract 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...

... 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...

... improved oil recovery from the Wainwright area was commenced. A review of polymer, surfactant, gas injection and thermal processes showed that they would probably not be economically competitive with the present waterflood. After some laboratory work and screening a caustic waterflood was initiated in the...

... potential of Alberta's oil reserves. A complete examination of our thinking on enhanced recovery is needed. Theexisting royalty incentives are apparently designed for low cost "Second Harvest" waterfloods, but are inadequate to encourage field tests of exoticprojects involving high cost LPG, micellar...
