CO2 flooding is now widely used as an enhanced oil recovery (EOR) technology and is also one of the most valuable CCUS processes. The interface characteristics of CO2 with crude oil and the rock matrix dynamically change during CO2 flooding. In this…
Asphaltene deposition is a ubiquitous problem in crude oil exploitation, which can cause the blockage of pore throat, leading to a significant reduction of oil recovery. Understanding the microscopic mechanism of asphaltene deposition and its…
Hydrogen is presently evaluated as a clean fuel to mitigate anthropogenic CO2 emissions and reduce the greenhouse gas effect. However, one of the major challenges for implementing a full hydrogen economy is hydrogen storage (as hydrogen is highly…
Geologic carbon storage projects aim to permanently trap large volumes of CO2 in reservoir rock sealed with low permeability layers. As high-pressure supercritical or liquid CO2 is injected, hydromechanical and chemical processes caused by the…
Thermal desorption (TD) behaviors of high-concentration petroleum-contaminated soil (PCS) are affected by soil properties, especially inorganic minerals, in the soil composition. In this study, the TD behaviors of petroleum-contaminated quartz…
Injection of supercritical CO2 (SCCO2) causes significant changes in the petrophysical properties of shales and affects the integrity of geological storage sites. The alteration of mineralogy and pore structure plays a major role in defining the…
Because the thermal release correlates directly with the success of in-situ combustion (ISC) technology, this research performs a series of investigations concerning thermal behavior and kinetics of heavy crude oil during combustion using high…
It is crucial to determine the sequence of reservoir tightening and hydrocarbon accumulation for analyzing the accumulation dynamics, oil migration mode, and oil distribution pattern of tight oil reservoirs. The tight sandstone reservoirs in the Fuyu…
The process of obtaining titanium tetrachloride (TiCl4) from the quartz-leucoxene concentrate (QLC) from the Yaregskoe oil-titanium field was studied. The carriers of titanium in the concentrate are leucoxene grains, which are polymineral aggregates…
Hydrocarbons are trapped at great depths with pressure and temperature higher than surface conditions which would vary depending on reservoir properties. When the well is set on production, these hydrocarbons travel through the wellbore over reducing…
The wettability of glass micromodels and sandstone rock processes plays a vital role in CO2 processes. There is a common belief that glass micromodels are a powerful tool to mimic the mechanisms involved in any EOR/IOR process qualitatively. However,…
