Bulk gels for permeability reduction in fractured and matrix reservoirs

open access: yesEnergy Reports, 2019
Having a high water cut reduces the economic viability of oil production. Water production increases, as less-viscous water tends to flow through high-permeability zones, leaving behind large volumes of unswept oil.

Permeability evolution and microstructural regulation of clay cement grouted body under coupled seepage and stress conditions [PDF]

open access: yesScientific Reports
Clay-cement grouted body (CCGB), as a green grouting material, have been widely applied in mine grouting water-blocking technology, and their permeability characteristics are of great significance to the safe mining of mines. Based on this, in this study,

Synthesis and Experimental-Modelling Evaluation of Nanoparticles Movements by Novel Surfactant on Water Injection: An Approach on Mechanical Formation Damage Control and Pore Size Distribution [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2020
Water injection is used as a widespread IOR/EOR method and promising formation damages (especially mechanical ones) is a crucial challenge in the near-wellbore of injection wells.

A new investigation on modeling of permeability reduction during CO2 flooding processes in sandstone oil reservoirs [PDF]

open access: yesNumerical Methods in Civil Engineering, 2014
Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered.

Permeability reductions induced by sorption of surfactant [PDF]

open access: yesWater Resources Research, 1997
Surfactant enhanced aquifer remediation (SEAR) is an attractive alternative to traditional pump and treat methods for remediating aquifers contaminated with nonaqueous phase liquids. However, initial studies indicate that the application of surfactant can reduce aquifer permeability by more than an order of magnitude, limiting the efficiency of SEAR. A

Cross-Linked Polyimide/ZIF-8 Mixed-Matrix Membranes by In Situ Formation of ZIF-8: Effect of Cross-Linking on Their Propylene/Propane Separation

open access: yesMembranes, 2022
Despite their potential for the scalable production of mixed-matrix membranes (MMMs), the MMMs prepared by the polymer-modification-enabled in situ metal–organic framework formation (PMMOF) process showed a considerable reduction in gas permeability as ...

Effect of Dry-Wet Cycles and Freeze-Thaw Cycles on the Antierosion Ability of Fiber-Reinforced Loess

open access: yesAdvances in Materials Science and Engineering, 2021
Compared with plain soil, polypropylene (PP) fiber-reinforced soil has markedly improved mechanical properties and can be used in slope protection projects.

Reduction of Capillary Permeability in the Fructose-Induced Hypertensive Rat [PDF]

open access: yesAmerican Journal of Hypertension, 1998
Impaired insulin transcapillary transport and the subsequent decrease in insulin delivery to target organs have been suggested to play a role in insulin resistance. These defects were studied in fructose-fed rats, an animal model with insulin resistance.
