Pore-Scale Analysis of Condensate Blockage Mitigation by Wettability Alteration
Energies, 2020 Liquid banking in the near wellbore region can lessen significantly the production from gas reservoirs. As reservoir rocks commonly consist of liquid-wet porous media, they are prone to liquid trapping following well liquid invasion and/or condensate ...

Pore-scale modelling of wettability alteration in microporous carbonates [PDF]
, 2016 While carbonate reservoirs are recognized to be weakly- to moderately oil-wet at the core-scale, wettability distributions at the pore-scale remain poorly understood. In particular, the wetting state of micropores (pores

A Novel Method with Dilute Surfactant Flooding by Considering the Effect of Time and Temperature on Crude Oil Aging, Experimental Study on Heavy Oil of Bangestan [PDF]
Journal of Chemical and Petroleum Engineering, 2017 Wettability alteration has been a sophisticated issue for scientists and reservoir engineers since early 20th century; thus, many investigations have been carried out to determine wettability and enhance it to ideal conditions, which leads to improvement

A Mechanistic Study of Wettability Alterations in Sandstone by Low Salinity Water Injection (LSWI) and CO2 Low Salinity Water-Alternating-Gas (WAG) Injection [PDF]
E3S Web of Conferences, 2023 Low salinity water injection (LSWI), an emerging Enhanced Oil Recovery (EOR) method, has proven to be effective in increasing oil recovery by wettability alteration. As low salinity water is injected into the reservoir, the pre-established equilibrium is

Evaluation and design of surfactant formulations for wettability alteration [PDF]
, 2020 Only about 35% of oil is recovered from carbonate reservoirs through primary and secondary flooding because of oil wet surfaces and unfavorable capillary pressures.

Salinity-dependent wettability alteration [PDF]
, 2020 Low salinity water flooding is a technique where, by injecting reduced salinity seawater, oil recovery can be significantly improved in some sandstone reservoirs. It has been generally agreed upon that this works predominantly by improving the water wettability of the reservoir rock.

Water Films, Asphaltenes, and Wettability Alteration [PDF]
SPE/DOE Improved Oil Recovery Symposium, 1998 Abstract We present a transport model for asphaltene diffusion from an oil/water interface through a water film followed by adsorption at a solid/water interface. Using a Langmuir adsorption isotherm, the effect of asphaltene aqueous solubility <md adsorption constant K on equilibration time are established ...
