In shale reservoirs, spontaneous imbibition is an important mechanism of fracturing fluid
loss, which has an important impact on enhanced oil recovery and water resource demand …

Liquid nanofluid (LNF) has been widely used for enhanced oil recovery (EOR) in tight oil
reservoirs in recent years. However, the mechanism of oil recovery by LNF flooding is still …

Due to the heterogeneity of the pore structure, there is still much residual fossil hydrogen
energy in the pore space. In this study, the distribution of residual fossil hydrogen energy …

Commonly, desorption of crude oil from rock surfaces accomplished by the exposure to the
decreasing salt concentrations of NaCl, Na 2 SO 4, MgCl 2 and CaCl 2 solutions. However …

Surfactant EOR received attraction due to its extreme capability to increase displacement
efficiency by altering the wettability, lowering the oil/water interfacial tension and ultimately …

Improved and efficient recovery methods are investigated as possible candidates to arrest
the production decline and to improve the injection capacity in hydrocarbon fields in …

Low interfacial tension (IFT) drainage and imbibition are effective methods for improving oil
recovery from reservoirs that have low levels of oil or are tight (ie, exhibit low oil …

Though renewable energy is developing rapidly, fossil energy remains to be the most
important source of energy and global oil consumption would keep rising to meet the needs …

The proved reserves and production from unconventional reservoirs, such as tight
sandstone, carbonate, and shale oil and gas, have increased yearly. How to effectively …

Wettability Alteration (WA) as an Enhanced Oil Recovery (EOR) technique is screened for an
oil wet carbonate offshore reservoir in this study. Surfactants can be used to change the rock …
