The key mechanisms in enhancing crude oil recovery include the reduction of interfacial
tension (IFT) between the trapped crude oil and the injected flooding solution, the wettability …

The oil production by the natural energy in oil reservoirs is decreasing gradually. Only 25–
30% of the world's reservoirs can be produced naturally, and different methods are …

Surfactant flooding is one of the most promising method of enhanced oil recovery (EOR)
used after the conventional water flooding. The addition of alkali improves the performance …

In this article, we present a holistic approach to predict the interfacial activity of
surfactant/polymer/nanoparticle stabilized Pickering nanoemulsions. Dynamic interfacial …

Demulsification using membranes is a promising method to coalesce highly stable
emulsified oil droplets for oil recovery. Nevertheless, a structure of the current filtration …

During the cementing process, the oil-well cement (OWC) inevitably comes into contact with
oil-based mud (OBM), which contaminates the OWC due to the incompatibility between OBM …

The interaction between crude oil and pore surfaces is notable in the process of CO 2 and N
2 flooding, and some crude oil can hardly be displaced and remains on pore walls in the …

Investigating the inherent wettability of rock surfaces at nanoscale is of great importance in
ore floatation and oil recovery field. Using molecular dynamics simulations, we …

The process of selecting an effective surfactant for wettability alteration is dependent on a
number of factors, including mineral type, temperature, salinity, and nature of adsorbed oil …

Displacement of methane (CH4) by injection gas is regarded as an effective way to exploit
shale gas and sequestrate carbon dioxide (CO2) simultaneously. To remarkably enhance …
