Low permeability sandstone reservoirs in China typically have more complicated geological
conditions, pore structures, and flow characteristics as compared to medium-to-high …

Spontaneous imbibition has become a role on the development of tight oil reservoirs. Many
oilfield cases have confirmed the validity of soaking to produce oil depending on imbibition …

The dynamic oil-CO 2 mixing and miscible flow in porous media are complex and important
phenomena that occurs during CO 2 injection for enhanced oil recovery (EOR) and …

The necessity of reducing the need for high horsepower to frack formation led to the use of
friction reducers intensively; however, the consequences of pumping friction reducers could …

Huff-n-puff by water has been conducted to enhance oil recovery after hydraulic fracturing in
tight/shale oil reservoirs. However, the mechanisms and capacity are still unclear, which …

In this experimental study, effects of injecting temperature and pressure on oil recovery
factor (RF) of shale oil reservoir was investigated by implementing cyclic cold nitrogen …

Tight oil reservoirs have become one of the main forces of oil production growth in the USA.
Only 3% to 7% of the oil can be recovered under primary depletion. Further improvement in …

Shale wells are often shut in after hydraulic fracturing is completed. Shut-in often lasts for an
extended period in the perceived hope of improving the ultimate oil recovery. However …

This work focuses on a typical low-permeability carbonate reservoir in Middle East that has
been developed by miscible hydrocarbon (HC) gas flooding for more than 10 years. The …

Effective spacer design is a key factor in cement's ability to produce a strong bond between
the cement-casing and the cement-formation. Mud displacement, mud cake removal, and …
