The stability study of CO2 foams at high pressure and high temperature
TL;DR: In this article, different surfactants and their mixtures were tested to evaluate their performance as CO2 foam agents, and the experiments were conducted using a visualized foam meter and a core flooding facility at high pressure and high temperature conditions.
Journal ArticleDOI
CO2 foam flooding for improved oil recovery: Reservoir simulation models and influencing factors
TL;DR: In this article, a mechanistic model of CO2 foam that allows for direct simulation of foam generation, propagation, coalescence and collapse was described, and a three dimensional heterogeneous conceptual reservoir model was then built to study the mechanisms of CO 2 foam flooding based on the foam model.

TL;DR: In this article, the corrosion rates of N80 steel under laboratory conditions with different oxygen content (21-5% vol%), total pressure (50-20MPa) and temperature (120-70°C) simulating HPAI in Dagang oil field in China were investigated using weight loss measurement.
Journal ArticleDOI
Dissolution of surfactants in supercritical CO2 with co-solvents
TL;DR: In this article, the dissolution of surfactant-like compounds in supercritical CO 2 in presence of co-solvents was investigated using a visualized PVT cell combined with UV spectrophotometer method at different pressures and 313 K.
Journal ArticleDOI
Occurrence state and forming mechanism of microscopic remaining oil controlled by dynamic and static factors
TL;DR: In this paper, the occurrence state and forming mechanism of multi-type microscopic remaining oil controlled by both static reservoir factors and dynamic development factors were quantitatively characterized and discussed based on waterflooding experiments on glass etching models and CT scanning on real cores.
