A hybrid enhanced oil recovery (EOR) method by combining low salinity water (LSW) and low salinity surfactant (LSS) flooding techniques was designed. Different
experiments were done to screen the Caspian seawater (SW) ...
Different oil displacement experiments conducted on sandstone and carbonate samples show that low salinity water (LSW) injection can reduce the residual oil saturation (ROS). Recently, surfactant flooding (SF) in combination ...

The use of engineered water (EW) nanofluid flooding in carbonates is a new enhanced oil recovery (EOR) hybrid technique that has yet to be extensively investigated. In this research, we investigated the combined effects ...
Very few thermodynamic models exist for estimation of density alteration due to solution of
CO2 in a pure H2O and CaCl2–H2O system. All of these models require density of CaCl2 solution to
estimate density of CaCl2–H2O–CO2 ...

The effects of different cation concentrations and types on rheological property and stability of Guar, Xanthan, and Partially Hydrolyzed Polyacrylamide (HPAM) cross-linked gels were analyzed through experiments. Also, a ...
In this paper, the effects of salinity and active ions on wettability alteration in carbonate
reservoirs with different initial wettability conditions with implications in smart water flood design,
optimization, and ...
The results of many previous studies on low salinity/controlled ions water (CIW) flooding suggest that future laboratory and modeling investigations are required to comprehensively understand and interpret the achieved ...

Around 70% of the total oil resources in the world are heavy. The primary heavy oil recovery is low due to the high viscosity and low mobility; hence, thermal enhanced oil recovery methods are widely applied to increase ...
To examine the effect of pressure on pore structure and petrophysical properties of carbonate rock, the porosity, permeability, CT scanning, SEM and elastic wave velocity of two carbonate core plug samples from an oilfield ...
Loss of drilling fluid is a common problem during the drilling of wells and it restricts the appropriate functionality of muds. Drilling fluid loss significantly increases drilling costs and non-productive time as well as ...

Formation damage caused by fine migration and straining
is a well-documented phenomenon in sandstone reservoirs. Fine
migration and the associated permeability decline have been observed
in various experimental studies, ...
The fast depletion of oil reserves has steered the petroleum industry towards developing
novel and cost-effective enhanced oil recovery (EOR) techniques in order to get the most out of
reservoirs. Engineered water–polymer ...

Tuning the salinity and concentration of potential-determining ions, such as Mg2+, Ca2+, and SO4
2−, could alter the wettability
toward a more water-wet state. The rate of alteration in carbonate rock wettability is a ...
Enhanced oil recovery (EOR) is a proven method to increase oil production from the brown fields. One of the efficient EOR methods is injecting surfactants to release the trapped oil. However, few unconsolidated behaviours ...

CO2 injection is one of the most promising techniques to enhance oil recovery. The most favorable properties of CO2 made this method popular and it has been widely used since 1950. Experimentally, the effect of CO2 injection ...
The salt formation creeping can signifcantly afect the casing stability, because of the changes in mechanical and geome chanical parameters. The creeping of Gachsaran salty formation in the south part of Iran has infuences ...

The significant loss of surfactants during reservoir flooding is a
challenge in oil field operations. The presence of clay minerals affects the
surfactant performance, resulting in surfactant losses. This is because ...
