ECO2N / ECO2M: handling of wettability in a dry zone
Hi folks, When exposing the initially brine-filled grid cells near injection point to CO2 injection, a dry zone is established. At a certain condition of flow and rock properties water saturation…

Using rock type "x" in T2Well
Hi T2well gives you the option to represent your tubular as a bundle of smaller tubes. I was trying to use rock type x (domain) right after the wellhead for representation of the wellhead choke.…

Pressure reporting: Tgh2-ECO2M
Hello ECO2M users, It is about pressure reporting of Tough2 when running a 1D radial model initialized with only water, flooded by CO2 at Its center using ECO2M. I get the following curves.…

JT Heat exchange in the cell containing well (using ECO2N)
Hello guys, In a non-isothermal run with gas (CO2) injection into an aquifer conditioned within supercritical domain of CO2, you expect some heating from compression and some cooling from expansion.…
