Re: The extent of CO2 injection cooling using ECO2N Just some additional info regarding the files: Only 1 rock type used: RESRK Relative Error Criterion of 1.0E-3 is trivial for speedy run, it also works with lower value but not much difference seen…

The extent of CO2 injection cooling using ECO2N
Hi all, Aiming at thermal QC of another code by using Tgh2-ECO2N, I made a simple coarse model with dimension 25x5x100 where dx=dy=200m and dz=4m, por & perm were 0.…

Re: Salt precipitation dependency on rate (and grid size) Just to add that the rock had kh=300md, kv=1md, h=200ft, q_high: 30kg/s, q_low:6kg/s and Van-Genuchten function used for relative perm and capillary pressure.

Salt precipitation dependency on rate (and grid size)
Hello folks; This is about testing salt precipitation in a 1D radial model with a single injection well at its center using ECO2N where capillary forces included and a pressure release well put on…

Temperature limits of various ECO2N versions
Hi Folks, Anybody can send me a few words on this: We have a version of ECO2N (as a part of iTough2.7.0.) which doesn't perform with T>103.4, same indication seen in CO2Tab data that is limited to…
