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.
E.6.3 • Automatic Shut-in
Go back to KAPPA Client 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.
In the tab ‘Shut in’, after clicking on ‘Start editing’ click on the ‘auto’ button .
The shut-in detection settings dialog appears:
Make sure that ‘analyze the signature of the
data’ is checked with the displayed option
selected.
Set the minimum pressure change for a shut-
in to be 200 psia and minimum shut-in
duration to be 1 hour.
Press OK.
All the BUs detected are highlighted according to the criteria. See figure below.
