Mechanisms for kerogen wettability transition from water-wet to CO2-wet: Implications for CO2 sequestration

Juan Zhou et al.

Summary: Geological CO2 sequestration is crucial for reducing greenhouse gas emissions and combating climate change. This study explores the wettability transition of kerogen from water-wet to CO2-wet under different CO2 pressures, finding that at high pressures, kerogen tends to be more CO2-wet, which is unfavorable for capillary trapping of CO2 but beneficial for CO2-EOR.

Diffusion Behavior of Methane in 3D Kerogen Models

Kai Bin Yu et al.

Summary: This study examines the diffusive behavior of methane molecules in kerogen matrices of different types and maturity levels, finding that methane self-diffusivity exhibits some degree of anisotropy and positively correlates with pore volume in Type II kerogens. Additionally, swelling of the kerogen matrix up to a 3% volume change is observed upon methane adsorption. These findings contribute to a better understanding of hydrocarbon transport mechanisms in shale, potentially leading to further development of extraction techniques.

CO2 enhanced gas recovery and sequestration in depleted gas reservoirs: A review

Ahmed Hamza et al.

Summary: Depleted gas reservoirs are considered safe and reliable storage sites for sequestering CO2, with the potential for cost reduction through incremental recovery of residual natural gas after CO2 injection. Research on CO2 adsorption/desorption characteristics in depleted gas reservoirs and applications in unconventional resources contribute to advancing CO2-EGR technology knowledge. Additionally, assessing ecological and economic impacts of storing CO2 in different reservoir types is important for understanding the overall effectiveness of CO2-EGR operations.

Molecular simulation study of CO2/CH4 adsorption on realistic heterogeneous shale surfaces

Kawthar Adewumi Babatunde et al.

Summary: Molecular simulation is widely used in adsorption studies, but realistic modeling and preparation of shale remains a challenge. Existing studies often use single components to represent shale surfaces, lacking the heterogeneity and mineral diversity of actual shale surfaces. The proposed molecular shale model exhibits higher adsorption capacity and surface area, providing a more accurate understanding of adsorption behaviors.

Insights into the Molecular Competitive Adsorption Mechanism of CH4/CO2 in a Kerogen Matrix in the Presence of Moisture, Salinity, and Ethane

Jiawei Li et al.

Summary: The study utilizes a hybrid methodology of molecular dynamics and grand canonical Monte Carlo simulation to investigate the effects of geological factors on gas adsorption and displacement mechanisms in CO2-enhanced gas recovery projects. Results show that moisture, salinity, and C2H6 have significant impacts on CH4 adsorption under different simulation conditions, providing valuable insights for better gas resource estimation and recovery enhancement in unconventional systems.

Kerogen nanoscale structure and CO2 adsorption in shale micropores

Aleksandra Gonciaruk et al.

Summary: Gas storage and recovery processes in shales are influenced by nano-scale porosity and chemical composition. Research shows that gas adsorption at low pressure is controlled by pore width rather than chemical composition. Nanoscale structure of kerogen includes various forms, allowing accurate prediction of gas sorption, storage, and diffusion properties in shales.

Effects of moisture, salinity and ethane on the competitive adsorption mechanisms of CH4/CO2 with applications to coalbed reservoirs: A molecular simulation study

Jiawei Li et al.

Summary: Injection of carbon dioxide into coal seam gas reservoirs is a popular method to enhance methane production, but factors like moisture, salinity, and presence of ethane can influence the efficiency of methane displacement by CO2. This study used molecular dynamics and Monte Carlo methods to investigate the adsorption properties of methane and the competitive adsorption behavior with carbon dioxide under different conditions. Results show that moisture, salinity, and ethane content all impact methane adsorption, with high moisture hindering methane adsorption, high salinity decreasing methane adsorption capacity, and high ethane reducing methane adsorption amount.

Dynamic fluid states in organic-inorganic nanocomposite: Implications for shale gas recovery and CO2 sequestration

Liang Huang et al.

Summary: This study conducted microscopic modeling for shale nanocomposites, revealing different gas recovery mechanisms during pressure depletion and CO2 sequestration. The study suggests CH4 adsorbed state as a potential target for enhanced shale gas recovery. Additionally, increasing water content reduces CH4 recovery during pressure depletion but improves CH4 recovery during CO2 injection.

Utilization of zeolite as a potential multi-functional proppant for CO2 enhanced shale gas recovery and CO2 sequestration: A molecular simulation study of the impact of water on adsorption in zeolite and organic matter

Kaiyi Zhang et al.

Summary: Water can suppress the adsorption of CO2 and CH4 when its content is high, but can enhance CO2/CH4 selectivity under certain circumstances. Kerogen shows a stronger preference for CO2 adsorption over CH4.

Kerogen Swelling in Light Hydrocarbon Gases and Liquids and Validity of Schroeder's Paradox

Zheng Li et al.

Summary: This study investigates the sorption of hydrocarbon gases and liquids in kerogen and the induced swelling of kerogen matrix. The results show that smaller hydrocarbon molecules have higher sorption and induced greater swelling in the kerogen matrix. Hydrocarbon liquids induce higher kerogen swelling than gases, leading to significant changes in pore structure in the kerogen matrix.

Direct gas-in-place measurements prove much higher production potential than expected for shale formations

Pedram Mahzari et al.

Summary: Novel high-pressure experimental techniques have demonstrated that gas in deep shale gas reservoirs may be up to five times higher than estimated by industry standard approaches, especially for heavier composition gases. The proposed instrumentation is reliable for quick assessment of gas in place potential, which could be useful for evaluating hydrocarbon reservoirs and geological carbon sequestration potential in a given formation.
