Application of nanoparticles for oil recovery.
(Peer reviewed; Journal article, 2021)Due to their large surface-area-to-volume ratio and enhanced chemical reactivity, nanoparticles have attracted interest among researchers in the upstream petroleum industry for oil recovery applications. Nanoparticles have ... -
A core flood and microfluidics investigation of nanocellulose as a chemical additive to water flooding for EOR
(Peer reviewed; Journal article, 2020)Cellulose nanocrystals (CNCs) and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (T-CNFs) were tested as enhanced oil recovery (EOR) agents through core floods and microfluidic experiments. ... -
Experimental Investigation of Polymer-Coated Silica Nanoparticles for Enhanced Oil Recovery.
(Journal article; Peer reviewed, 2019)Recently, polymer-coated nanoparticles were proposed for enhanced oil recovery (EOR) due to their improved properties such as solubility, stability, stabilization of emulsions and low particle retention on the rock surface. ... -
Experimental investigation of polymer-coated silica nanoparticles for EOR under harsh reservoir conditions of high temperature and salinity.
(Peer reviewed; Journal article, 2021)Laboratory experiments have shown higher oil recovery with nanoparticle (NPs) flooding. Accordingly, many studies have investigated the nanoparticle-aided sweep efficiency of the injection fluid. The change in wettability ... -
Experimental investigation of stability of silica nanoparticles at reservoir conditions for enhanced oil-recovery applications
(Peer reviewed; Journal article, 2020)To be effective enhanced oil-recovery (EOR) agents, nanoparticles must be stable and be transported through a reservoir. However, the stability of a nanoparticle suspension at reservoir salinity and temperature is still a ... -
Experimental investigation of the effect of adding nanoparticles to polymer flooding in water-wet micromodels
(Peer reviewed; Journal article, 2020)Recently, the combination of conventional chemical methods for enhanced oil recovery (EOR) and nanotechnology has received lots of attention. This experimental study explores the dynamic changes in the oil configuration ... -
High salinity and high temperature stable colloidal silica nanoparticles with wettability alteration ability for EOR application.
(Peer reviewed; Journal article, 2021)The stability of nanoparticles at reservoir conditions is a key for a successful application of nanofluids for any oilfield operations, e.g., enhanced oil recovery (EOR). It has, however, remained a challenge to stabilize ... -
High-Temperature Core Flood Investigation of Nanocellulose as a Green Additive for Enhanced Oil Recovery
(Journal article; Peer reviewed, 2019)Recent studies have discovered a substantial viscosity increase of aqueous cellulose nanocrystal (CNC) dispersions upon heat aging at temperatures above 90 °C. This distinct change in material properties at very low ... -
Identification of Nanocellulose Retention Characteristics in Porous Media
(Journal article; Peer reviewed, 2018)The application of nanotechnology to the petroleum industry has sparked recent interest in increasing oil recovery, while reducing environmental impact. Nanocellulose is an emerging nanoparticle that is derived from trees ...
