Although new energy has been widely used in our lives, oil is still one of the main sources world. After application traditional recovery methods, there are a large number layers that have not exploited, and need to further increase meet urgent for world economic development. Chemically enhanced (CEOR) considered be kind effective technology, which achieved good results field, but these technol...

In this study, nanoparticle stabilized foam experiments were performed in bulk tests, micromodels, and sandpacks at elevated temperatures and pressures to investigate the flow behavior and displacement mechanisms for enhanced heavy oil recovery. The results from the bulk tests showed that the stability of the foam and oil in water (O/W) emulsion improved when silica nanoparticles (SiO2) were ad...

The poor rock quality and matrix permeability several orders of magnitude lower than conventional oil reservoirs observed in unconventional liquid reservoirs (ULR) presents many uncertainties on the storage capacity of the rock and the possibility of enhancing recovery. The technological advances in multiple stage hydraulic fracturing and horizontal drilling have improved the overall profitabil...
