Parameters interactive modification
Accessible from the toolbar or the popup menu with 'Modify', this option lets you grab the
decline curve on the plot, and modify the parameters as you move the mouse in the plot:
Up/down moves change qi.
Left/right moves change Di.
Up/down moves with the Shift key pressed change b.
The following options are also implemented:
Plot type
The plot scale can be set to: q vs t, log(q) vs t (default), log(q) vs log(t), q vs Q, log(q) vs Q.
Add Plot
This option will add an Arps plot in the current view.
Show model
The display of the simulated rate/cumulative can be toggled on/off (off by default).
Show cumulative
When relevant, the cumulative can be displayed (data and decline curve).
Sample/filtered data
With less than 1000 rate points the plot shows by default the actual data. When more points
are present the sampled version, based on the number of points per cycle given in the
extraction dialog, is used.
Change the scale to q vs t and Show the cumulative, Figure B01.14.
Right-click in the plot to access the Change plot type option and select q vs t.
