Abstract Foam stabilized by a surfactant has been used successfully for mobility control during enhanced oil recovery processes, but the stability of foam limits its application. Aqueous foams prepared from dispersions partially hydrophobic silicon dioxide (SiO 2 ) nanoparticles and sodium dodecyl sulfate (SDS) anionic were studied injection behavior solution SDS or dispersion SiO /SDS analyzed comparison. increased with increasing nanoparticle concentration although feasibility producing...
For the ultra-high water-cut reservoirs, after long-term water injection exploitation, physical properties of reservoir change and heterogeneity becomes increasingly severe, which further aggravates spatial difference flow field. In this study, displacement experiments were employed to investigate variations in core permeability, porosity, relative permeability a large amount injection. A endpoint model was proposed by utilizing alternating conditional expectation (ACE) transformation...

Abstract Capillary dominated flow or imbibition—whether spontaneous forced—is an important physical phenomena in understanding the behavior of naturally fractured water-driven reservoirs (NFR’s). When water flows through fractures, it imbibes into matrix and pushes oil out pores due to difference capillary pressure. In this paper, we focus on modeling quantifying recovered from NFR’s imbibition processes using a novel fully implicit mimetic finite (MFD) approach coupled with discrete...
Foam has found wide application in enhanced oil recovery (EOR) and shown promising potential for efficient CO2 geological storage. Although the process of current foam modeling is adequate, especially transient flow characteristics heterogeneous porous media, it still at an immature stage. Previous studies based on models were too complex to be easily applied practical situations. To address this lacuna, we used a simple but robust stochastic bubble population balance model involving only...
SAGD (steam-assisted gravity drainage) technique is one of the most efficient thermal recovery technologies for exploiting Mackay River thin layer oil sand reservoirs.
