Errors when compiling TOUGH2 ECO2N

Hello Every one, When I compiled the TOUGH2 ECO2N in Microsoft Visual Studio, I met the problem as follow, could you please tell me how to solve it? I have added T2CG2.f, MA28.f, MESHM.f, T2f.…

how could FLAC3D simulate the deterioration of soil when coupling with TOUGH

I am read many essay about FLAC3D+TOUGH, including FLAC3D+TOUGH2 and FLAC3D+TOUGH+HYDRATE, and i have completed the couple with FLAC3D AND TOUGH+HYDRATE,…

Relative permeability curves in tough2

Hello Every one I faced problem with the relative permeability curve while I working with tough2.1 to build a 3D reservor model for CO2 storage by using both the source code and also the petrasim…

Confining beds option geothermal doublet

Hello, Does anybody have a benchmark problem or an example for a geothermal doublet (with 1 production well and 1 injection well) in a porous aquifer using the confining beds option (MOP(15)=1)?…

Blank MESH

Hello Stefan! I'm running the sample problems and I'm having a problem with the Heat Sweep in a Vertical Fracture for EOS1 - rvf input file. I'm creating a meshmaker with the characteristics given…

No convergence in NSIN at - non-isothermal simulation T2WELL/ECO2N

Dear TOUGH community users, I am trying to simulate CO2 injection using T2WELL/ECO2N. In the model, the grid is radial and both wellbore and reservoir are initially fully saturated with water X3=0.…

Who can send me a TMT2 program, thank you

I need to convert the grid generated by GMS to tough2 format

applying heat load in BHE and varying input T?

Hi all, I am using T2Well with TOUGH2 to model a borehole heat exchanger and was wondering if it was possible to apply a heat load to the BHE? I have tried something of the form below:…

Pressure vs CO2 DG

Hi everyone, I've asked my self a question that i can't find a plausible answer, i hope that you can help me with this. It regards to CO2 injection at 15 ºC and 33 MPa on a reservoir…

T2WELL/ECO2N problem with mass rate

Dear TOUGH2 community users, I am new to T2Well and I am trying to simulate pure gas-CO2 injection with several radial wellbore cells and only one big reservoir cell,…

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.…

Using TOUGH ECO2N for Core flooding

Hi all, I am curious to know if TOUGH2 is able to model a core flooding. Suppose that there is a core sample of length 30 CM. I have tried, however my simulation didn't converge.…

T2Well semi-analytical solution in reservoir

Hi all, I notice in the T2Well manual that you can turn on a semi-analytical solution of the reservoir by setting thermal conductivity in well cells to a negative value.…

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).…

Incorporating dip angle in meshmaker

Hello, I am trying to model a gently dipping aquifer, and am setting up the grid using the online meshmaker utility. The input field called "Angle between Y-axis and the horizontal" is meant to help…

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.…

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,…

Dear all, I am working with TOUGH2 Landfill Bioreactor Model (T2LBM) to simulate a biological reaction in my domain which stimulates by injecting oxygen.…

FOFT keyword no printing

hi. I have been trying to select the elements of my interest to print out in the forward.out or another time series file like in the manual examples by using FOFT in my forward input file but…

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.…

Residual and solubility trapping

Hello everyone. I am working on Co2 storage using both ECO2N answer ECO2M. In the result we have 1-sg which represents the saturation of CO2 in gas phase.…

immature termination

Hi all, I'm trying to model an experiment where I had a cylinder filled with sand and some headspace on the top. The sand had some solvent in it. The whole cylinder was initially at about 100 degC…

Pore Compressibility in ECO2M

Hi guys, I have a 3D cartesian model where I assign constant porosity across all elements in the model. In TOUGH2, I think we can assign only a constant value of pore compressibility.…

T2Well questions

Hi there, Starting to play around with T2Well and having good fun. ;) Two things (at least) that I didn't understood: 1- ROCKS data block: the domain name for wellbore cells starting with 'x'.…
