The demand for lithium (Li) has greatly escalated during the past decade and is predicted to increase continuously with the market growth of the electrified transportation and renewable energy, given that Li–ion batteries are the major energy storage method for these sectors. In spite of the urgent need of satisfying the increasing demand of Li, so...

Carbon dioxide (CO2) storage and sequestration is regarded as an effective approach to mitigate greenhouse gas emissions. While injecting an enormous amount of CO2 into carbonate-rich aquifers, CO2 dissolves in the formation brine under the large pressure and the subsequently formed CO2-enriched brine reacts with the calcite. Reaction-induced chang...

Secondary recovery methods such as waterflooding are often applied to depleted reservoirs for enhancing oil and gas production. Given that a large number of discretized elements are required in the numerical simulations of heterogeneous reservoirs, it is not feasible to run multiple full-physics simulations.

Feasibility of exploration and exploitation of geothermal energy from Enhanced Geothermal Systems (EGS) involves consideration of flow in naturally occurring fractures and faults. However, seismic imaging of fractures and faults in geothermal systems is difficult because the same fluid (hot brine) fills the fractures and faults as fills the matrix...

With the goal of detecting and characterizing faults and fractures in enhanced geothermal systems (EGS), a new technology involving CO2 push-pull testing, active-source geophysical imaging, and well logging has recently been proposed. This technique takes advantage of (1) the contrasting properties of supercritical CO2 and water which cause CO2 to...

Low oil price necessitates the efficient production of hydrocarbon from heavy oil reservoirs. Steam Assisted Gravity Drainage (SAGD) has been the prevalent process for mobilizing heavy oil and bitumen by steam injection. SAGD, however, has economic and technical issues relevant to low energy efficiency and high steam-oil-ratio. Solvent-aided therma...

Response authorities for the Gulf oil spill in 2010 were concerned that far-field surface slicks may have originated from an underground failure of the Macondo well after capping and before plugging. Bureau of Ocean Energy Management and Lawrence Berkeley National Lab carried out subsurface modeling to test scenarios of multi-phase hydrocarbon fluid escaping through failed casing. The goal was to determine if broaching could occur at the seafloor within a time frame of regulatory concern.
