Charge Control and Wettability Alteration at Solid-Liquid Interfaces

SPE Improved Oil Recovery Symposium, 2014
Abstract Most solid surfaces acquire a finite surface charge upon exposure to aqueous environments due to desorption and/or adsorption of ionic species. The resulting electrostatic forces play a crucial role in many fields of science, including colloidal stability, self-assembly, wetting, and biophysics as well as technology.

Impact of Wettability Alteration on Recovery Factor

SPE/DGS Saudi Arabia Section Technical Symposium and Exhibition, 2011
Abstract Recovery Factor is one of the key elements in determining commercial viability of hydrocarbon fields. It has been recognized that the recovery factor, apart from other parameters, depends on wettability of the reservoir rocks which in turn affects calculations of other parameters used in the volumetric equation.

Wettability alterations due to aging in crude oil; wettability and Cryo-ESEM analyses

Journal of Petroleum Science and Engineering, 2003
Abstract Several studies of fluid distribution and wettability on the pore scale have been reported, but to our knowledge, none of them have attempted to obtain quantitative measurements. In this paper, quantitative wettability results from Cryo Environmental Scanning Electron Microscopy (Cryo-ESEM) are reported and compared to wettability ...

Evaluation and design of surfactant formulations for wettability alteration

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. Surfactants, with their dual hydrophobic and hydrophilic nature have been known to improve oil recovery significantly by lowering oil-water interfacial tension and by altering wettability ...

Wettability alteration for carbonate and sandstone formations

In tight carbonate reservoirs, waterflood recovery rates are typically low due to their inherent heterogeneity and oil-wet or mixed-wet characteristics. Wettability alteration is a promising approach for enhancing oil recovery in such reservoirs. Conversely, sandstone reservoirs often exhibit water-wet characteristics attributed to the presence of ...
