PLC SHIFT
WELL TEST
Oil and gas well testing solution with AGA/API compliant measurement and simplified reporting
WELL TEST cost effectively measures gas, oil and water production from several wells in close proximity to each other. Manual or automated valves are used to direct the flow from a single well through a test separator. This separator employs measurement devices and flow computers to determine flow accumulation for each component (gas, oil and water) over a set period of time.
Key Features
Seamless Integration With PLC SHIFT Flow apps
Connects internally to PLC SHIFT Gas Flow and Liquid Flow apps for configuration, control, and status of the apps.
Well Configurations
Store up to 20 individual well configurations including
Gas Composition
Liquid density - For API Corrections
Liquid Product Type - ie Crude Oil, NGL - For API Corrections
Base Density of Oil and Water - Inferred Water Cut
Correction Factor Oil
Correction Factor Water
Well Test Control
Select Well on Test
Start/Stop Test
End Purge Manually
Advanced Data Handling
Each well has a configurable "Asset ID" This is a unique identifier that is included in all data records generated by all connected Flow Computer apps.
Each well test has a unique "Batch ID". The same batchID is and included in all data records generated by all connected Flow Computer apps.
These two identifiers make reporting trivial in SCADA and SQL database systems as it provides a reliable key to join and filter data across dozens of data tables.
We have built a sample report with interactivity using Microsoft Power BI desktop reporting tools. Desktop format can be found online at this link. A simpler version that is suitable for mobile devices is here.
