Understanding polymer retention is a critical aspect in the field of chemical-enhanced oil
recovery (cEOR). This article presents a comprehensive review of polymer retention in …

Gas injection is amongst the oldest and most used enhanced oil recovery (EOR) methods in
the petroleum industry. Nevertheless, gas EOR is subject to poor macroscopic sweep …

Surfactants can significantly improve the oil recovery of spontaneous imbibition (SI) in
unconventional oil reservoirs, but mathematical modeling of surfactant SI for displacing oil in …

Due to the complex physical properties of low-permeability glutenite reservoirs, the oil
recovery rate with conventional development is low. Surfactants are effective additives for …

Switchable ethoxylated amine surfactants are readily soluble in CO2 and high-saline brines.
The objective of the current work is to maximize the foamability and stability of CO2 foam at …

One of the major drawbacks of using foam to reduce the gas mobility in oil fields is its
stability at harsh reservoir conditions. A key factor that impacts the foam stability is the type …

Generating strong and stable foam is necessary to achieve in-depth conformance control in
the reservoir. Besides other parameters, the chemistry of injection water can significantly …

Indonesia merupakan salah satu negara yang memproduksi minyak bumi yang cukup besar
sekitar 1, 5 juta barel per hari, tetapi saat ini mengalami penurunan produksi yang sangat …

The in-situ generation of foam while injecting gas is well recognized due to its effectiveness
in lowering the gas mobility and, hence, improving the sweep efficiency in porous media …

Abstract (EN) The application of surfactants and polymers in carbonate reservoirs has a high
potential with emerging technology of the manufacture of these chemicals. Tertiary or …
