Detected build ups
Clicking on the node ‘Shut-in indicator’ displays the all the BU’s detected.
Before using these multiple build ups for analysis, we need to clean and adjust the production
history in order to synchronize it with the pressure history.
Note: Although the automatic detection is very useful and can significantly speed up the data
pre-processing stage, it is based on an algorithm which may sometimes come up with incorrect
limits if the pressure build-up exhibits such behaviors as irregular humping, soft shut-ins, very
noisy shut-ins, etc. In these situations, you can correct the limits manually or semi
automatically. In our current case, the selection made automatically can be kept.
