Dualstream 2

Smart solution for high liquid wet gas wells

Dualstream 2 is a 3-phase measurement solution for allocation or monitoring gas condensate wells. It is typically used on a per well basis at the wellhead or in the flow line on wells with high liquids.

Standard field instrumentation makes Dualstream 2 ideally suited for remote wellheads or unmanned platforms.

Common applications include tie-ins to existing infrastructure or new field development where real time high accuracy gas measurement is a fundamental operation requirement and water measurement accuracy is required for efficient well operation.

Dualstream 2 replaces the need for test separators or tracer dilution techniques.
