Hussain, A.A.A. (author), Vincent-Bonnieu, S.Y.F. (author), Kamarul Bahrim, R. Z. (author), Pilus, R. M. (author), Rossen, W.R. (author)As foam is injected into an oil reservoir, the region near an injector can become oil-free due to the relatively high capillary number. Foam created in this region encounters oil further out in the reservoir. The impact of oil on foam in porous media is usually investigated by co-injecting surfactant, gas and oil, or by injecting pre...journal article 2020

Hussain, A.A.A. (author)Foam flooding can be applied in soil-remediation techniques or for improving oil recovery processes in petroleum reservoirs. There are models which aim to predict the behaviour of foam in presence of oil in bulk and in porous media, however these models are not very reliable. In this work we investigate different ways in which a specific crude...doctoral thesis 2019

Hussain, A.A.A. (author), Vincent-Bonnieu, S.Y.F. (author), Kamarul Bahrim, R. Z. (author), Pilus, R. M. (author), Rossen, W.R. (author)Dispersed and solubilized oil can impact bulk foam stability differently. Though aromatic components are more soluble in water than straight-chain aliphatic components, solubilized aromatics do not necessarily impact the stability of foam in bulk or porous media, whereas straight-chain aliphatic components can have a detrimental impact (Bergeron...journal article 2019

Eftekhari, A.A. (author), Farajzadeh, R. (author)We investigate the validity of the assumption that foam in porous media reduces the mobility of gas phase only and does not impact the liquid-phase mobility. The foam is generated by simultaneous injection of nitrogen gas and a surfactant solution into sandstone cores and its strength is varied by changing surfactant type and concentration. We...journal article 2017

Liu, Y. (author), Salemink, H.W.M. (author)A planarized on-chip nanophotonic sensor based on a photonic crystal cavity is realized in this work. The sensor was embedded in a solid protecting material (flowable oxide) with perfect filled holes: this eliminates problems of fouling in practical applications. The functional area of the sensor is created by carefully removing the...journal article 2017
