Description |
Overview Pflotran_coupling_data defines data required to couple ParaGeo with Pflotran or Pflotran-OGS. When coupling ParaGeo with a reservoir simulator like Pflotran, generally only the reservoir and the most permeable formations (including permeable faults) will be solved by the reservoir simulator and consequently only those formations will existin the flow grid whereas the ParaGeo model geometry will generally consider all the formations in the overburden plus any underburden and side burden. Hence the data from Pflotran model grid will be mapped to the equivalent formations (groups) in ParaGeo.
The data required is dependent on the coupling options, with the minimal data being the list of ParaGeo groups in the geomechanical model for which the flow will be solved by Pflotran or Plotran-OGS.
