Geomechanical evaluation of CO2 underground disposal is complex and can be even more challenging in coal reservoirs due to natural fractures and combined effects of multi-component transport. The objective of the research work presented in this paper…
By conducting relative permeability experiments of multi-cycle gas-water displacement and imbibition on natural cores, we discuss relative permeability hysteresis effect in underground gas storage during multi-cycle injection and production. A…
CO2 injection into a reservoir with marginal permeability ( 1014 m2) could induce pressure high enough to fracture the reservoir rock and/or caprock. A pressure-driven fracture can immensely enhance the injectivity and would not compromise the…
Recently, the oil and gas industry started to experience a major evolution that could impact the geophysical community for decades. The effort to reduce greenhouse gas emissions will lead to more renewable energy and less fossil fuel consumption. In…
The industrial development of Xinjiang is facing serious carbon emissions and water shortage problems in this region. It is urgent to find a sustainable development way. CO2 geological storage combined with enhanced water recovery (CO2-EWR) is a…
Storage of large amounts of carbon dioxide (CO2) within deep underground aquifers has great potential for long‐term mitigation of climate change. The U.S. Gulf Coast is an attractive target for CO2 storage because of the favorable formation…
Natural gas hydrates, crystalline solids whose gas molecules are so compressed that they are denser than a typical fluid hydrocarbon, have extensive applications in the areas of climate change and the energy crisis. The hydrate deposit located in the…
