A review of wettability alteration using surfactants in carbonate reservoirs

open access: yesAdvances in Colloid and Interface Science, 2021
The wettability of carbonate rocks is often oil-wet or mixed wet. A large fraction of oil is still remained in carbonate reservoirs, it is therefore of particular significance to implement effective methods to improve oil recovery from carbonate reservoirs.

Alteration of wettability and wettability heterogeneity

Journal of Petroleum Science and Engineering, 2002
Abstract This paper emphasizes how wettability may be altered for special core analysis purposes and by which processes this occurs. Studies of how the imbibition characteristics change after aging core plugs in crude oil are reported, focusing on imbibition rate and endpoint saturations and on the induction time.

Wettability alteration for carbonate and sandstone formations

open access: yes
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 ...

Impact of Wettability Alteration on Recovery Factor

open access: yesSPE/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.
