WGS Wet gas measurement
Highly flexible and economical solution for well performance optimisation
- Venturi based metering systems for wet gas (gas volume fraction 90...99%)
- Well performance verification and well management
- Smart diagnostics and system fault monitoring
The KROHNE Venturi based wet gas solutions, WGS 1000 / 2000 / 3000, are designed to measure the flow of unprocessed gas directly from the well. Intermediate parameters at the point of measurement are calculated from known reservoir and well compositions and used to generate fraction and density tables for the operational range of the well or reservoir.
The WGS wet gas measurement systems are capable of determining flowrates of dynamically changing well streams with a high accuracy of ±1...3%. Compared to a test separator, the WGS system is space-saving, can be implemented much quicker and requires low maintenance. The WGS 1000 / 2000 / 3000 comes with three different variants for basic to very demanding applications. Each wet gas system is based on a wet gas Venturi meter with computational supervisory software, providing continuous validation and smart diagnostic features. The whole project management from consultation to instrumentation, integration, service and support is provided by KROHNE.
