Syntax >> VOLUME (phase_name/PHASE: iphase) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> MATERIAL >>> MODEL   Description This command selects as an observation type the total volume of phase iphase. This observation type refers either to the entire model domain or to the subdomain defined by a list of rock types. The phase name […]

Syntax >> USER (: anno) Parent Command > OBSERVATION Subcommand >>> CONNECTION >>> ELEMENT >>> MODEL >>> SOURCE Description This command selects a user-specified observation type. This option enables a user to introduce a new observation type, i.e., any type of data can be used for parameter estimation by defining the corresponding model output which

Syntax >> TOTAL MASS (phase_name/PHASE: iphase/ comp_name/COMPONENT: icomp) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> MATERIAL >>> MODEL   Description This command selects as an observation type the total mass of phase iphase or component icomp. This observation type refers either to the entire model domain or to the subdomain defined by a list

Syntax >> TIMES: ntime (EQUAL/LOGARITHMIC) (time_unit) or >> TIMES from DATA/OBSERVATIONS Parent Command > OBSERVATION Subcommand –   Description This command selects points in time during a TOUGH2 run at which the calculated system response is used for subsequent iTOUGH2 analysis. In the case of inverse modeling, these are the calibration times at which calculated

Syntax >> TEMPERATURE (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects temperature as an observation type. This observation type refers to an element. Example > OBSERVATION >> TEMPERATURE >>> ELEMENT : TCP_1 deg(C)=(deg(F)-32)*0.55 >>>> SHIFT : -32.00 >>>> FACTOR : 0.55 >>>> temperature DATA in deg(F) on file: temp.dat

Syntax >> SUBSIDANCE (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects displacement, i.e., subsidence (negative) or uplift (positive), as an observation type. Approximate, one-dimensional deformations are calculated based on porosity changes induced by changes in fluid pressure and/or temperature. No stress-strain calculation is performed. Relative porosity changes calculated by

Syntax >> SECONDARY (phase_name/PHASE: iphase) (: ipar) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects thermophysical properties, which are so-called “secondary parameters” in TOUGH2, as an observation type. This observation type refers to an element. The secondary parameter refers to elements of TOUGH2 vector PAR (see Pruess [1991], Figure

Syntax >> SATURATION (phase_name/PHASE: iphase) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects phase saturation as an observation type. This observation type refers to an element. The phase name phase_name or phase number iphase, which depend on the EOS module being used, are listed in the iTOUGH2 header. They

Syntax >> RESTART TIME: ntime (time_unit) (NEW) Parent Command > OBSERVATION   Subcommand –   Description This command selects points in time at which step changes are to be made to individual elements or element groups. At this specific point in time, the user can either change the element’s volume, porosity, permeability, or any of

Syntax >> REGULARIZATION (FILE: file_name) (BETA: beta) Parent Command > OBSERVATION > PARAMETER   Subcommand –   Description This command identifies pairs of parameters that are used to calculate a smoothness regularization term. Weighted differences between the two estimated values are added to the objective function. The pairs are identified by the ordering number in
