Abstract Carbon dioxide (CO 2 ) injection is implemented into the reservoir to further improve oil production efficiency, by mixing with at condition, and becomes miscible. The miscibility affects become swelled less viscous thus easily flow through reservoir. Most of EOR projects has higher recovery factor in miscible condition. Therefore, this article aims determine effects on Cornea Field. F...

Carbon dioxide is a typical kind of greenhouse gases, and the oil gas field recovery ratio could be significantly improved by injecting it into formation. The main goal to increase in early stage studying injection miscible flooding. With advancement “carbon neutral” strategy China, application CO 2 flooding technology, which aims enhance Chinese oilfields, has been further expanded. developmen...

Gas injection into carbonate formations is one of the most important activities to protect oil reserves that can guarantee a steady production. On-time injection of enough gas can result in the recovery of billions barrels of oil. In addition, it can preserve a huge amount of gas for the next generations. If the reservoir depth is shallow, or the reservoir fluid has a little amount of intermedi...

Asphaltene deposition is a common phenomenon during CO2 flooding in ultralow permeability reservoirs. The deposited asphaltene occupies the pore volume and decreases permeability, resulting serious formation damage well productivity. It urgent to investigate mechanisms, adverse effects, preventive measures. However, few investigations have been systematically conducted by now. In this research,...
