...% OOIP. Numerical simulation recommended two commercial size pilots, a 3-pattern and a 5-pattern of irregular five spots, with forecast incremental oil recovery factors of 5.6% OOIP over waterflood. Geologic uncertainty is the greatest challenge in the oil and gas industry, which is exacerbated with any...

... provided the most top results (28.35% OOIP). In this work, we presented a new method to inject Alkaline-Surfactant-CO 2 -LS water successively. The tertiary oil recovery can reach ~34% of the OOIP for all the cores in this study. The new process can improve the sweep efficiency as well as increasing oil...

... cations Na + . Low-salinity waterflooding showed a high potential to improve oil recovery in the SI experiments at different temperature levels. For high permeability Buff Berea cores, the SI oil recovery ranged from 38 to 69% OOIP, while oil recovery of the low permeability Bandera cores ranged from 17...

... as a result of reducing injected water salinity in both coreflood and spontaneous imbibition experiments. Coreflood experiments showed an increase in oil recovery by 3 to 5 % of OOIP, while spontaneous imbibition experiments showed an increased by 16 to 21 %. Additionally, spontaneous imbibition experiments...

The cyclic water injection experiments above oil bubble point pressure increased oil recovery by additional 2.9% of Oil Originally In Place (OOIP) above ordinary water flood. This effect can be attributed to the hasten imbibition of water into the matrix during...

... progressively increased ultimate recovery. The example fields will achieve a range of incremental increases in the recovery factor of between 8 and 20 percent original oil-in-place (% OOIP) or up to 50% OOIP increase over conventional primary recovery.
