A PLT (Production Log Tool) plot is a special well plot for comparing observed production (well flow rates) and simulated production. The curves are plotted as production against measured depth (MD). Simulated production data is retrieved directly from the grid model or from the corresponding (*.rft) files, while observed production data are loaded from well log files (*.las).
There are several ways to create new PLT Plots
From Project Tree in the Plot Main Window
From the Project Tree in the Main Window
From the 3D view
To be able to plot observed production data for a well, a well log file containing that data must be imported. Production data in a well log file is expected to have column names:
|Oil||QOZT, QOIL, _xxxxQOIL|
|Gas||QOZT, QGAS, _xxxxQGAS|
|Water||QGZT, QWAT, _xxxxQWAT|
|Total||QTZT, QTOT, _xxxxQTOT|
To be able to plot simulated data for a well, the trajectory for that well have to be imported. If no well trajectory is found, ResInsight will present a warning dialog to the user.
The property editor lets the user select which curves to display in the PLT plot.
Select the well to display in the plot. Only observed well paths are displayed.
After a well has been selected in the Well Name field, sources for that well should appear in the sources field. The sources are placed in one of three different groups:
WRFTPLTin the Eclipse manual for information)
When the user selects a source, time steps for that source appears in the Time Steps field.
The Time Steps field contains available time steps for the selected source(s). Some combinations of selected sources may display a filtered list of time steps instead of the union of all time steps for all selected sources. The policy is as follows:
Each time step is postfixed by an indication of which source type(s) the time step is belonging to. This indication is displayed as one or more letters within square brackets. Examples: [ O ], [ R G ].
More than one letter for one single time step, means that the time step belongs to multiple case types.
The curve selection group lets the user control which component(s) of the PLT data to display.
This property editor lets the user control how formations are handled. This is what it looks like in the PLT plot context.
Please see the full documentation on the formations property editor for details.
When the formation names property editor is used in the context of PLT plots, the fields Trajectory and Simulation Well are hidden because those values are given by the PLT plot definition.
This property editor lets the user control visual properties for the legend and axis.
The PLT plot displays groups of curves. A group consists of the components oil, gas and water. The curves within a group are stacked, the biggest component first.
