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.…

T2well output files
Hello T2well users; I have just started using the code. I run a case with only a well model (reservoir represented solely by the last grid block at the bottom).…

Re: JT Heat exchange in the cell containing well (using ECO2N) Appreciate your rapid help here, as usual. I am aware of the +/- effects upon "where" in the envelope one might be. But I got a better understanding of sole P and delta-H dependency now,…

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.…

Re: T2Well-ECO2N wellbore-annulus modelling Thank you Yingqi, I am sure his publications give a lot of insight and include perhaps the topic I brought up. Just to clarify more, I was looking for a practical example where wellbore and annulus…

T2Well-ECO2N wellbore-annulus modelling
Hello T2well-ECO2n users and advisors I am a new user of T2well, but familiar with Tough2 and several EOSs. Due to a limited number or limited variation in modelling samples following the code,…

Re: The extent of CO2 injection cooling using ECO2N Hi Yingqi, I tried the constant temperature approach and the results look much more realistic, it is also in line with what you obtained by using enthalpy.…

Re: The extent of CO2 injection cooling using ECO2N I might have used wrong pressure (288 bar: initial pressure), but it wasn't sensitiv to pressure at all- in that area of around 300bar. Godarzi

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.…
