Effect of water-extractable carboxylic acids in crude oil on wettability in carbonates
(Journal article, 2011)The acidic components of the crude oil have a profound effect on the initial wetting conditions and possible wettability alteration by seawater in carbonates. In this work, three types of crude oils with different ... -
The effects of pH, time and temperature on the stability and viscosity of cellulose nanocrystal (CNC) dispersions: implications for use in enhanced oil recovery
(Journal article; Peer reviewed, 2017-08)Cellulose nanocrystals (CNC) are currently being investigated as potential additives for enhanced oil recovery (EOR). Presented in this paper is a study investigating the effects of different physical and chemical environments ... -
Numerical treatment of two-phase flow in capillary heterogeneous porous media by finite-volume approximations
(Journal article; Peer reviewed, 2012)This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, ... -
“Smart water” as a wettability modifier in chalk: The effect of salinity and ionic composition
(Doctoral thesis; Journal article; Peer reviewed, 2010)Seawater can improve the water wetness of chalk at high temperatures, which improves the oil displacement by spontaneous imbibition of water. It is experimentally verified that the interaction between Ca2+, Mg2+, and SO42− ... -
The Effect Of Titanium Nitride(TiN) Nanoparticle On The Properties & Performance Bentonite Drilling Fluid
(Journal article; Peer reviewed, 2017)In recent years, the application of nano technology is attracting the oil and gas industry. Nanomaterials research results show an improving result of cement, drilling fluid and Enhanced Oil Recovery. In this paper, the ... -
Water-based enhanced oil recovery (EOR) by “Smart Water”: optimal ionic composition for EOR in carbonates
(Journal article; Peer reviewed; Doctoral thesis, 2011)The composition of the injecting brine has a profound effect on the efficiency of water-based enhanced oil recovery (EOR) methods. Recently, we observed that not only is the concentration of the active ions Ca2+, Mg2+, ... -
Wettability alteration in carbonates: the effect of water-soluble carboxylic acids in crude oil
(Journal article; Peer reviewed; Doctoral thesis, 2010)Acidic components in crude oil influence the wetting condition through their effect on electrostatic interactions with the mineral surfaces. In this paper, we have extracted water-soluble acids from a crude oil with a high ...
