Low permeability oil and gas resources are rich and have great potential all over the world,
which has gradually become the main goal of oil and gas development. However, after …

Despite rapid advances in renewable energy extraction and utilization, global oil demand
continues to rise. Oil displacement technologies are widely studied and applied because …

Enhanced oil recovery (EOR) plays a significant role in improving oil production. Tertiary
EOR, including surfactant flooding, can potentially mobilize residual oil after water flooding …

To investigate the contribution of hydrophobic groups of hydrophobically modified
polyacrylamide (HMPAM) to stabilizing crude oil emulsion, the β-cyclodextrin (β-CD) …

To economically and environmentally recover oil from reservoirs and promote CO 2
utilization (CU) project, CO 2 responsive surfactants have been developed to undertake …

Surfactants when interacted with reservoir rock surfaces undergo adsorption, which can
intensively break the process by diluting surfactant formulation, thereby promoting additional …

In order to investigate the flow behavior and oil displacement of ultralow interfacial tension
(IFT) surfactant flooding, the experimentally validated computational fluid dynamics …

In order to solve the serious problem of oil shortage, the improvement of the emulsification
effect of surfactants using nanoparticles was proposed to enhance oil recovery. In this work …

In this study, a compound surfactant system composed of alkyl polyglucoside (APG) and
amine oxide (OAE) was formulated to synergistically stabilize the oil-in-water emulsion for …

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 …
