Pre-salt reservoirs are among the most important discoveries in recent decades due to large quantities of oil them. However, high levels uncertainties related its gas/CO2 production prompt a more complex management, including use alternating water and injection (WAG) as recovery mechanism increase from field. The purpose this work is develop methodology manage cycle sizes WAG/CO2, analyze impac...

In this study, oil production and retention were observed compared in 72 reservoir simulation cases, after which an economic analysis for various CO2 prices was performed. Reservoir cases comprise different combinations of water alternating gas (WAG) ratios, permeabilities, well distances. These models set at three depths; thus pressure temperature conditions, to see the impact miscibility on s...

the experimental study and modeling of gravity drainage during water alternative gas injection, wag process, in carbonate rock for one of the iranian off-shore reservoir at lab-scale were carried out. the mechanism of gravity drainage during the wag process, and its contribution to the oil recovery in the fractured carbonate reservoirs were also studied. in the wag process alternatively gas is ...

The enhanced oil recovery mechanisms in fractured reservoirs are complex and not fully understood. It is technically challenging to quantify the related driving forces their interaction matrix fractures medium. Gravity capillary play a leading role process of reservoirs. This study aims performance EOR methods using dimensionless numbers. A systematic approach consisting design experiments, sim...

Machine learning algorithms are extensively used to reduce the complexity of applied problems in various fields, including energy. Accurate prediction performance water alternating gas (WAG) injection as an enhanced oil recovery (EOR) process is great importance optimal management hydrocarbon resources. In current work, a hybrid mathematical model proposed for near-immiscible WAG process. We us...

More than half of all recoverable oil reserves are found in carbonate rocks. Most these fields highly fractured and develop different zonations during primary secondary recovery stages; therefore, they require a developmental approach conventional reservoirs. Experimental results for water-alternating gas injection [WAG] foam-assisted [FAWAG] under tertiary conditions were used to investigate e...

Optimization studies are an important task in reservoir engineering practices such as production optimization and EOR (Enhanced Oil Recovery) assessments. However, they extensive with many simulations that require huge computational effort resources. In terms of EOR, CO2 injection is one the most common methods employed due to a high recovery potential environmental benefits. To assess feasibil...
