Paper presented at the SPE EuropEC - Europe Energy Conference featured at the 84th EAGE Annual Conference & Exhibition, June 5–8, 2023
Paper Number: SPE-214427-MS
... Several studies aimed to examine the potential of using DES to improve oil recovery. Results of experiments conducted by Mohsenzadeh through core flooding tests revealed a marked increase in oil recovery at various temperatures. The CU12 solution proved to be more effective than CG12 because...

Paper Number: SPE-214419-MS
.... Microfluidic tests showed the volumetric sweep efficiency increase by surfactant compared to brine, and core flood tests revealed the driving mechanism of oil recovery. Arab et al. ( Arab et al. , 2022 ) designed an experimental program for alkaline-surfactant-polymer flooding in viscous oil systems...

Paper Number: SPE-209645-MS
... Abstract Miscible hydrocarbon (HC) rich gas injection is a common EOR technique included in the development plan of many Abu Dhabi oil fields. This technology, that provides a very high oil recovery, requires the supply of a gas that is very valuable for other uses or its commercialization...

Paper Number: SPE-209651-MS
... Abstract The average recovery factor of current producing oil reservoirs is about 35-50% worldwide. Enhanced Oil Recovery (EOR) methods such as Water Alternating Gas (WAG) target the oil left in place and improve the final recovery of the developed fields. In a WAG injection plan, some...

... during fluid restoration and oil displacement. The results showed only small differences in oil recovery by spontaneous imbibition and viscous flooding at high and low rate, proving that capillary forces and spontaneous imbibition were major contributors to the oil mobilization and production process...

Paper Number: SPE-209671-MS
... Abstract Smart water injection (SWI) and carbonate water injection (CWI) have been successfully used in enhanced oil recovery (EOR) due to favorable crude oil-brine-rock interactions. In this study, these two EOR methods are combined as one hybrid EOR process namely carbonated smart water...

... injection velocity, this non-wetting phase invading pressure is a function of the viscosity of the oil being displaced. For the same viscosity ratio, oil recovery monotonically increases with increasing injection velocity suggesting that the flow regime is viscous-dominant for all the viscosities studied...

... due to gas recycling if the gas injection rate was maintained as per Gi/Gp target. This resulted in lower oil recovery and lower revenue from gas export. Furthermore, some injectors were also not injecting as per target due to poor reservoir quality and mechanical issues. Lessons captured from 19...

... focusing on the TAN and aging effects it was observed that in all cases, the early time production is slower and final oil recovery is larger comparing to non-aged core plugs. This data confirms the change of rock surface wettability towards more oil-wet state after ageing and reverse wettability...
