Depending on the size of the data set, we can load data either by choosing:
Add new gauge (mirror)...
or
Add new data (no filter)...
For a large size data set we
must
load the data as 'New Gauge'. It presents the advantage to
create a mirror of the data set that will display only a reduced number of points (around
1/1000 points) for the sake of preview.
The mirroring method is designed to optimize handling of large data set: Filtered Dataset can
then be created under a ‘Mirror Gauge’ node, and we can create as many samples as needed,
by adjusting the filter settings according to the needs of analyses.
When faced with a small sized dataset, we can load the pressure as 'New Data' directly. As the
option says, no filter is applied and the complete set of points will be displayed and
manipulated entirely. In case of large amount of data set, the 'Add new Data' option should
not be used as the data display and its manipulation would be extremely slow.
Note:
right-clicking on one of the nodes below the ‘production’ group displays a pop-up menu
will only allows loading as complete data (without filter) and not as mirror gauge. This method
as said earlier is meant for low number of data points. As we have here real-time flowmeter
data for production rate, we need to go through the mirroring method for loading. This
procedure to load filtered production data will be described later in chapter
E.4
. Let us for the
moment focus on how to load pressure data.
Select 'Add new gauge'.
In the 'Data source' dialog select the 'Training Bli' created by the IT engineer. Press 'Next'.
You are then connected to the 'simulated database'.
In the 'Tag Search' dialog press on ‘Search’ to display the available tags.
EcrGS01p contains the pressure data and EcrGS01q the production data.
Select EcrGS01p, then press on ‘Get limit date’ and ‘Get # records’ to display the main
statistics of the pressure channel.
