Dear All,
This is a part of PI to EC project.
We’re are now working on SCADA instrument tag type selection to automate Well Test data transformation from SCADA to PI and to EC.
We would like to see your SCADA or DCS which you usually read the well test results and record in our worksheet manually before you key-in into EC.
If you have using 100% of well test results from SCADA excel file please and upload it to EC, please confirm us.
Let me share my experience about well test problem of Platong that I’ve visited them last week.
In PLCPP,PLCPP2, there was an issue that well test result tag on the Well test result screen of SCADA is not quite stable. After operator command SCADA to perform well test, some platform didn’t get active in the screen, so operator couldn’t record any well test result of WHP from the screen.
The well test result in the Excel file which has been exported around 1.00AM is using different tag we called “platform level tag” , CST program the report to pull well test result from this tag instated of using result tag of the well test result screen.
Theoretically, both tag types should have the same values, but it was founded that it is not equal, Our current assumption is PLC clock resulting in this problem.
Additional problem is Excel file from SCADA doesn’t contained all well test results of that day, so they have to use the test result from SCADA well test monitoring screen by copying from SCADA (Test monitoring screen) to excel and average or spot the value and record in his worksheet, before input to EC.
EC&PI has to use only tag type, currently, I got endorsement to use Result Tag of Well Test Result Screen, but it will be a limitation for some asset doesn’t have well test result screen.
