Enzymes have recently been considered as possible agents for enhanced oil recovery (EOR) acting at the liquid–solid interface. One way to assess this is via measuring the wettability of calcite surfaces, important for EOR methods in carbonaceous reservoirs. In the present work, we have experimentally investigated the effect of enzymes on the wettability of calcite mineral surfaces with oil–brin...

Polymer flooding is now considered a technicallyand commercially-proven method for enhanced oil recovery (EOR). The viscosity of the injected polymer solution is the key property for successful polymer flooding. Given that the viscosity of a polymer solution has a non-linear relationship with various influential parameters (molecular weight, degree of hydrolysis, polymer concentration, cation c...

Transport of emulsions in porous media is relevant to several subsurface applications. Many enhanced oil recovery (EOR) processes lead to emulsion formation and as a result conformance originating in the flow of a dispersed phase may arise. In some EOR processes, emulsion is injected directly as a mobility control agent. Modeling the flow of emulsion in porous media is extremely challenging due...

The mobility profiles of gases used in enhanced oil recovery (EOR) have been thoroughly investigated through the coupling operations data mining oilfield and experimental analyses. Mobility as an EOR objective function has not previously applied to characterize potential reservoirs for selection application, even though it is a robust combinatorial that benefits from two petrophysical var...

Currently the waste generated from public consumption in Indonesia is very high. One such used palm oil households and food companies. Utilization of this research by recycling into surfactants which will be Enhanced Oil Recovery (EOR) process. The surfactant concentrations were 1.3%, 1.5%, 2%, 2.2% 2.5%. began with refining cooking banana peels for 24 hours. In order to make surfactants, mixed...

objective: to evaluate the current scientific evidence for the applicability, safety and effectiveness of pathways of enhanced recovery after emergency surgery (eras). methods: we undertook a search using pubmed and cochrane databases for eras protocols in emergency cases. the search generated 65 titles; after eliminating the papers not meeting search criteria, we selected 4 cohort studies and ...

The work aimed to solve the problem of determining, validating, and transferring model parameters flooding using chemical enhanced oil recovery (EOR) from a core experiment full-scale hydrodynamic model. For this purpose, digital describing process displacement by surfactant polymer solution on is created matched achieve convergence with historical data. This approach allows uncertainties assoc...

Increasing oil consumption in Indonesia encourages an improvement of production using chemical flooding Enhanced Oil Recovery (EOR) technology. Chemical is injection method materials based on polymer and nanoparticles such as α-Fe2O3-xanthan gum nanocomposite into the reservoir. In this study, α-Fe2O3 were synthesised then blended to xanthan by sonochemical through ex-situ process. The X-ray di...
