Syntax >> FLOW (phase_name/PHASE: iphase) (component_name/COMPONENT: icomponent) (HEAT) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> CONNECTION   Description This command selects as an observation type the total fluid flow rate, flow of a given phase, total component rate, rate of component in a given phase, or total heat flow rate. This observation type refers […]

Syntax >> ENTHALPY (phase_name/PHASE: iphase) (CHANGE/DELTA) Parent Command > OBSERVATION Subcommand >>> SINK Description This command selects as an observation type the flowing enthalpy in a production well. This observation type refers to a sink code name. If multiple elements are provided, the flowing enthalpy is weighted by the individual production rates. If a phase

Syntax >> DRAWDOWN (phase_name/PHASE: iphase) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects as an observation type the pressure drawdown during a pumping test. This observation type refers to one or more elements. The drawdown is calculated from a reference pressure, which is the pressure at the specified element at

Syntax >> CUMULATIVE (comp_name/COMPONENT: icomp) (phase_name/PHASE: iphase) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> SOURCE   Description This command selects as an observation type the cumulative injection or production of component icomp or phase iphase. This observation type refers to a sink or source code name. It can be used when time-dependent generation rates

Syntax >> COVARIANCE (FILE: file_name) Parent Command > OBSERVATION   Subcommand –   Description This command reads the diagonal elements of the a priori covariance matrix Czz. Usually the variances of the observations are specified separately for each data set using command >>>> DEVIATION (o), or they are provided as a separate column along with

Syntax >> CONTENT (phase_name/PHASE: iphase) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects as a parameter the content of phase iphase as an observation type. Phase content is defined as the product of saturation and porosity. The phase name phase_name or phase number iphase, which depend on the EOS

Syntax >> CONCENTRATION (comp_name/COMPONENT: icomp) (phase_name/PHASE: iphase) (CHANGE/DELTA) Parent Command > OBSERVATION   Subcommand >>> ELEMENT   Description This command selects as an observation type the concentration [kg/m3] of a component in a given phase. Concentration is defined as the product of mass fraction of component icomp in phase iphase times density of phase iphase.

Syntax >>>> WEIGHT: 1/sigma Parent Command all third-level commands in block > PARAMETER and > OBSERVATION Subcommand –   Description (see >>>> DEVIATION (p/o)) Example (see >>>> DEVIATION (p/o)) See Also >>>> DEVIATION (p) | >>>> DEVIATION (o)

Syntax >>>> VARIATION: sigma Parent Command all third-level commands in block > PARAMETER Subcommand – Description This command specifies the expected variation sigma of a parameter p. sigma is used to scale the columns of the Jacobian matrix, yielding dimensionless and comparable sensitivity coefficients. While the solution of the inverse problem is not affected by
