Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) technique in
which the dissolved CO 2 can transfer to the oil phase to improve the oil mobility and to …

Over the past decade, the wide-spread implementation of laboratory-based X-ray micro-
computed tomography (micro-CT) scanners has revolutionized both the experimental and …

Carbon dioxide (CO 2) injection into geological formations is gaining global interest.
Examples include CO 2 storage to mitigate greenhouse gas emissions and water alternating …

The displacement of brine by CO 2 is an important process controlling plume migration and
initial pore-space utilization in geological CO 2 storage. We present CO 2–brine unsteady …

Studies of the rock matrix acidizing for enhanced recovery of oil or gas have entirely focused
on the fully water saturated conditions. In fact, matrix acidizing can be conducted in low …

Injection of acids into carbonate formations can lead to the formation of macroscopic flow
conduits. These so-called wormholes have the potential to dramatically increase effective …

Sandstone and carbonate core samples were challenged with a two-phase supercritical CO
2 and brine mixture to investigate the effects of chemical processes on the physical …

In chalk reservoirs, acid injection for well stimulation purposes as well as certain EOR
methods, such as CO2 injection, causes dissolution of the chalk matrix due to the acidic …

The geological storage of carbon dioxide is a promising method to reduce greenhouse gas
emissions to the atmosphere and to meet demanding climate targets. It is also a key enabler …

With the discovery of sizeable sour gas fields in recent years and the reduction of sulfur
prices, the economic unattractiveness has been added to the operational and environmental …
