Application of iron oxide nanoparticles in oil recovery – A critical review of the properties, formulation, recent advances and prospects
(Peer reviewed; Journal article, 2022)Iron oxide nanoparticles (IONPs) are of particular interest in multiple fields and in enhanced oil recovery (EOR) due to their unique advantages and characteristics. Albeit several laboratory research articles on IONPs in ... -
Asphaltenes subfractions extracted from Brazilian vacuum residue: Chemical characterization and stabilization of model water-in-oil (W/O) emulsions
(Journal article, 2018)Asphaltenes were obtained from a Brazilian vacuum residue (VR) by precipitation with different ratios of n-heptane/VR to give three asphaltene subfractions. The behavior of these different subfractions in relation to the ... -
Early field planning using optimisation and considering uncertainties - Study case: Offshore deepwater field in Brazil
(Peer reviewed; Journal article, 2021)During early phases of oil field development, field planners must decide upon the optimal number of wells and optimal field plateau rate, usually by performing sensitivity studies. These design choices are then “frozen” ... -
The effect of upstream inlet choking and surfactant addition on the performance of a novel parallel pipe oil-water separator
(Peer reviewed; Journal article, 2020)This paper reports the effect of inlet choking and addition of surfactant on the performance of a parallel pipe oil-water separator. These two issues can have a strong effect on oil-water separation in real hydrocarbon ... -
Emulsions in porous media from the perspective of produced water re-injection – A review
(Peer reviewed; Journal article, 2021)During offshore production, it is typical to discharge produced water into the sea after treating it to a level that meets environmental regulations. A growth in the volumes of produced water and increasingly stringent ... -
Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition
(Peer reviewed; Journal article, 2022)Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ... -
Inhibitor-wax interactions and PPD effect on wax crystallization: New approaches for GC/MS and NMR, and comparison with DSC, CPM, and rheometry
(Journal article; Peer reviewed, 2019)Three pour point depressants (PPDs) with different chemistries, and extracted asphaltenes were studied in their influence on wax crystallization in a model system. A new procedure for nuclear magnetic resonance (NMR) was ... -
Measuring filter-cake cohesive strength and flowability
(Peer reviewed; Journal article, 2022)The filter-cake has a critical role in temporarily reducing the permeability of the wellbore to prevent issues such as lost circulation, formation damage, wellbore collapse and differential sticking. The filter-cake's ... -
Microfluidic investigation of enhanced oil recovery: The effect of aqueous floods and network wettability
(Peer reviewed; Journal article, 2021)Rock wettability significantly influences underground oil extraction efficiency during enhanced oil recovery (EOR) processes. We experimentally examine the effect of wettability on oil recovery at pore-scale using ... -
Non-linear dependency of wax appearance temperature on cooling rate
(Journal article, 2018)The Wax Appearance Temperature (WAT) is usually the first parameter to consider, when assessing whether paraffin wax contained in the crude oil can become an issue during production. As such, correct determination of the ... -
Potential applications of magnetic nanoparticles within separation in the petroleum industry
(Journal article; Peer reviewed, 2018)Magnetic nanoparticles have unique properties such as extremely large surface area per volume substance and strong magnetic response. In addition, the possibilities for surface functionalization make them exciting candidates ... -
Pour point depressant efficacy as a function of paraffin chain-length
(Peer reviewed; Journal article, 2022)Pour point depressant (PPD) activity mechanisms include solubilization, morphology alteration, and steric/entropic repulsion. A wealth of complex intermolecular interactions governs PPD efficacies in real crude compositions. ... -
Rheological properties of highly concentrated dense packed layer emulsions (w/o) stabilized by asphaltene
(Journal article; Peer reviewed, 2015)Dense packed layers (DPLs) were sedimented and removed from various asphaltene stabilized w/o emulsion batches, and contained aqueous phase volume fractions (ϕ) between 0.701 and 0.808. These values are close to the ...
