CO 2 –Water–Oil–Salt–Rock Interactions on Reservoir Properties, Enhanced Oil Recovery, and CO 2 Storage: A Mini Review

Zhichao Zhang, Qinghe Gao, Mingliang Zhu, Huijuan Qian et autres

The injection of carbon dioxide (CO 2 ) into reservoirs triggers complex physical and chemical interactions among CO 2, water, oil, salt, and rock, affecting the seepage properties of reservoirs and the effect of CO 2 -enhanced fluid (oil or saltwater) recovery …

Enhancing CH4 extraction and CO2 sequestration in archaeal membrane under varied CO2 conversion rates: Insights from MD simulations

Lu Wang, Huili Zhang, Minyuan Wang, Chang He et autres

CO2 can be geologically sequestered through solidification reactions or biochemically converted into CH4 by methanogenic archaea. To explore the diffusion and transport behaviors of CO2 and CH4 through membranes under varying CO2 conversion rates, molecular dynamics (MD) simulations were performed at 333 …

Optimization of CO 2 Injection for EOR and Storage in Low-Permeability Reservoirs

Qiaozhen Chen, Zhichao Zhang, Yu Liu, Mingxing Bai et autres

Based on the issue of low efficiency of CO 2 displacement and sequestration in different low-permeability reservoirs, the impact of different CO 2 injection methods (continuous CO 2 injection, water-alternating-gas (WAG), and Huff and Puff (HnP)) on the microscopic oil production and …

Soil water and salt transport in seasonally frozen cropland: isotopic tracing method with geochemical modelling

Huili Zhang, Chengwei Wan, Grzegorz Skrzypek, John J. Gibson

Understanding the dynamics of water and salt migration in seasonally frozen agricultural soils is critical for effective arid land management. This study combined field monitoring with a three-method extraction strategy for stable isotope analyses (direct vapor equilibration, centrifugation, and cryogenic vacuum distillation). …

Enhanced coagulation performance of hydrophobic-modified carbon quantum dots in polymeric sulfate for oil-contaminated wastewater treatment

Guohua Song, Guolin Jing, Zhengnan Sun, Huili Zhang et autres

Oil-contaminated wastewater containing emulsified oil can severely pollute water bodies. Due to the action of surfactants, emulsified oil forms a stable emulsion system, making it difficult to remove through static separation methods. However, high-efficiency coagulants can purify the oil-contaminated wastewater, bringing it …

Research progress on the treatment of polymer flooding produced water by flocculation/coagulation: A minin Review

Gang Liu, Zhaoxian Chen, Limin Wang, Huili Zhang et autres

In the middle and late stages of oilfield development, water becomes a critical medium for enhancing oil recovery. Most major oilfields have adopted polymer flooding and ternary composite flooding as primary extraction techniques. However, the increased recovery efficiency is accompanied by the …

Determining superconvergence points for L2−1σ scheme of variable‐exponent subdiffusion and error estimate

Hongying Huang, Huili Zhang, Xiangcheng Zheng

Abstract We develop a numerical scheme for subdiffusion of variable exponent by combining the temporal discretization with finite element spatial approximation. In existing works, determining the superconvergence points requires solving a nonlinear equation related to the variable exponent at each time step. …

Taken as an Exploiting Tool: When ESOPs Meet Controlling Shareholders' Share Pledging in an Emerging Market

Huili Zhang, Jigao Zhu, Kam C. Chan

ABSTRACT We examine firms' underlying motivation for adopting an employee stock ownership plan (ESOP) in the presence of share pledging (SP) by controlling shareholders. Empirical evidence shows that an SP firm is more likely than a non‐SP firm to adopt an ESOP. …
