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 are to be estimated where the total amount of injected or produced fluid
is approximately known, or if the total generation rate is prescribed in
block GENER, but the phase composition of the produced fluid is variable and
sensitive to the parameters of interest. Finally, the cumulative amount of
injected or produced fluid can be used as an observable variable for wells
on deliverability. Note that the cumulative mass of a phase produced in an
element strongly depends on the composition of the produced fluid mixture
according to the options provided by TOUGH2 flag MOP(9). Component number
icomp or component name comp_name, and phase number iphase or phase name
phase_name depend on the EOS module being used. They are listed in the
iTOUGH2 header and can be specified either on the command line or using the
two subcommands
Example
