Numerical studies of long-term wettability alteration effects in CO2 storage applications [PDF]

open access: yes, 2021
The wettability of the rock surface in porous media has an effect on the constitutive saturation functions that govern capillary pressure and relative permeability.

Role of divalent ions, temperature, and crude oil during water injection into dolomitic carbonate oil reservoirs

open access: yesOil & Gas Science and Technology, 2019
Although wettability alteration has been shown to be the main control mechanism of Low Salinity and Smart Water (LS-SmW) injection, our understanding of the phenomena resulting in wettability changes still remains incomplete.

Applying low-salinity water to alter wettability in carbonate oil reservoirs: an experimental study

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Seawater has been widely used as an injection fluid for maintaining pressure in sandstone and carbonate reservoirs. In the literature related to EOR research, it was noted that diluted seawater (low-salinity water) can highly improve recovery due to the ...

Wettability Alteration of Carbonate Rocks by Polyelectrolyte Complex Nanoparticles [PDF]

open access: yes, 2019
More than fifty percent of oil reservoirs around the world are carbonate reservoirs. Oil recovery from carbonates requires closer attention due to the heterogeneity of the rock and its wettability system.

Oil recovery and wettability alteration in carbonates due to carbonate water injection

open access: yesJournal of Petroleum Exploration and Production Technology, 2017
Enhanced oil recovery in carbonates due to wettability alteration has received much attention recently. In contrast to sandstones reservoirs, carbonates are neutral-wet or preferentially oil-wet.

Wettability Alteration of Limestone Carbonate Cores Using Methylene Blue and Alumina-Based Nanofluid: Implications for EOR

open access: yesApplied Sciences, 2023
Wettability is a key parameter for optimizing the residual oil recovery from geological rock formations and it provides a path for improved oil recovery and geo-storage of energy.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

A comprehensive evaluation of the effect of key parameters on the performance of DTPA chelating agent in modifying sandstone surface charge

open access: yesHeliyon, 2023
Despite the positive aspects of low salinity water (LSW), this technique is relatively expensive and unavailable in some countries. Furthermore, potential problems associated with LSW such as scale precipitation in carbonate reservoirs and fine migration

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

open access: yesMolecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Underlying Mechanisms of Tight Reservoir Wettability and Its Alteration

open access: yes, 2018
The wettability of tight reservoir rock plays a critical role in affecting relative permeability and in turn oil recovery. However, the link between wettability and its effects on oil recovery remains poorly understood, and the potential to boost oil ...
