... Abstract Formation wettability alteration (WA) is ubiquitous in nature and relevant to many applications spanning from geological CO 2 storage to enhanced oil/gas recovery. WA and the induced capillary dynamics are of great significance in caprocks and shale reservoirs. However, the impact...

... cut in all wells decreased to about 96%. The TMO Nanofluid worked by providing a unique long-term wettability alteration, reducing the interfacial tension, allowing the chemicals to be retained in the fracture/reservoir phase. It also functions to remove near-wellbore organic formation damage via...

Imbibition tests were carried out on oil-wet cores to observe the response of oil production and optimize the experimental...

... improving oil recovery beyond that obtained by standard waterflooding, due to wettability alteration, which improves reservoir sweep efficiency. However, to be economically viable compared to seawater injection, the Smart Water must be cheap, easily available, and must substantially improve oil production...

... wettability alterations in organic pores and fractures that depend on the types and maturities of kerogen. The DSA results indicated that the air/water-contact angle decreases after the reaction, regardless of the types and maturities of kerogen, while the higher level of maturity of kerogen led to a greater...

... treatments can increase the relative permeability to condensate liquid by factors of 1.89 and 1.22 respectively, due to the wettability alteration mechanism. Capillary pressure calculations show that GS can reduce the capillary pressure by around 40% on average, while TCF leads to a 70% reduction...

... interfacial tension (IFT) reduction by surfactant, capillary imbibition, favorable wettability alteration by ketone, and osmotic low-salinity brine imbibition. The IFT decreased to 1.79 mN/m upon addition of non-ionic surfactant to low-salinity brine, and it reduced to 2.96 mN/m in a mixture of 3-pentanone...

... Abstract The potential of tuned-composition waterflooding to enhance oil recovery from carbonate reservoirs has been widely investigated in the literature. The consensus is that wettability alteration occurs because of the electrostatic interactions between the carbonate rock surface...

... The potential application of acetate and formate as a wettability alteration method comes from the expected interaction between a positively charged calcite surface and a carboxyl group. In this research, therefore, we aim to verify once again the efficacy of glycine and compare it to possibly...

... Abstract Even though the influence of wettability alteration on imbibition is well-documented, its synergy with Interfacial-Tension (IFT) for Alkali/Nanoparticles/Polymer flooding requires additional investigation. Particularly, when the oil Total Acid Number (TAN) may determine the wetting...
