Recent advances of surfactant-stabilized N2/CO2 foams in enhanced oil recovery
TL;DR: In this paper, the authors focused on the promising surfactant formulas and their corresponding mechanisms under different reservoir conditions, especially harsh conditions, and provided clues to N2/CO2 foam EOR design and also promoted the development of harsh reservoirs.

Single-step silica nanofluid for improved carbon dioxide flow and reduced formation damage in porous media for carbon utilization
TL;DR: In this paper, the use of single-step silica nanofluids, of controllable nanoparticle (NP) size (below 100nm), for improved CO2 flow and reduced formation damage in porous and permeable media.
Journal ArticleDOI
Different strategies of foam stabilization in the use of foam as a fracturing fluid.
TL;DR: The results of both experiments and simulations indicate that foam additives play an essential role in foam stability and the synergic effects of surfactants and nanoparticles exhibit more favorable performance.
Journal ArticleDOI
Oil recovery enhancement in low permeable and severe heterogeneous oil reservoirs via gas and foam flooding
TL;DR: In this paper, the trinal-core flooding experiments about gas flooding (N2 and CO2), WAG injection and foam flooding were conducted on the base of the simulation of SH reservoir conditions.
Journal ArticleDOI
Experimental investigations to evaluate surfactant role on absorption capacity of nanofluid for CO2 utilization in sustainable crude mobilization
TL;DR: In this article, a new colloidal solution of anionic surfactant (i.e., sodium dodecyl sulfate, SDS, 0.16-0.24) and polymer based single-step silica nanofluid of varying concentration (0.1-1.0) was proposed for subsurface carbon utilization in CO2 absorption, IFT reduction, and fossil fuel displacement.

TL;DR: In this article, the electrophoretic mobility of oil droplets, dispersed without any surfactant in the aqueous phase, was measured and the results showed that the oil droplet are negatively charged and the magnitude of their ζ-potential strongly depends on pH and the ionic strength of the aiquous phase.

The Viscosity of Carbon Dioxide
TL;DR: In this paper, the authors proposed a new representation for the viscosity of carbon dioxide, which is valid up to 300 MPa for temperatures below 1000 K, whereas for higher temperatures and owing to the limitation of the equation of state used, the upper pressure limit is restricted to 30 MPa.
