Enhanced Oil Recovery Technologies, 2nd Volume

Dear Colleagues,

For many years, there has been a clear trend of increasing energy demand. Despite the energy transition, oil and natural gas will remain as the main energy sources for the next several dozen years. As the reservoir is depleted during primary recovery, oil recovery becomes increasingly difficult, even though the deposits are not yet completely recovered. Therefore, it is essential to develop innovative methods to increase oil recovery from known reservoirs. Enhanced oil recovery (EOR) has been considered the most promising technology to increase the recovery factor. This issue’s goal is to further disseminate the results of basic research, laboratory investigations, and field testing or implementation in the following areas: 

• Studies of fluids and interfaces in porous media; 
• Complex interfacial rheology and multiphase flow;
• Fundamental research on surfactants and polymers; 
• Development of techniques for gas flooding (CO₂, N₂, foam, etc.);
• Thermal recovery;
• Emerging technologies, including smart water and microbial EOR;
• Hybrid technology;
• Related technologies, including carbon capture and sequestration (CCS);
• Artificial intelligence/machine learning/deep learning applications in EOR techniques.
