Fig.D01.3 • Shut-in express
If we wanted to carry on with a real analysis, the first step would be to visit the Main
Information section of the Saphir document to enter the proper Test and PVT parameters. We
will not do it in this session.
Close the Saphir file (do not save).
Note: you can select several shut-ins periods and still use ‘Shut-in express’ . By doing so,
when in Saphir you will have multiple build-ups or fall-offs extracted at the same time in the
loglog plot and the semilog plot, very useful for comparison.
D01.3 • Automatic Shut-in
Go back to Diamant and stay in the EcrGS01p Fltd data node. This time we are going to use
the automatic shut-in functionality to define all the build-ups in one go. This option allows the
user to define multiple shut-ins in the history using an algorithm which considers the pressure
behaviour and shape.
Click right on the node, then above the plot window, click on to reset the
channel to 0. You can do this by right clicking on the shut-in Indicator node as well. All the
defined shut-in periods will be erased.
Click on the EcrGS01p Fltd data node and display the plot.
Click on the button .
