Roxar Multiphase Salinity System
Data Sheet
Direct, continuous measurement of water conductivity in a multiphase flow
Measuring conductivity / salinity of the produced waterfrom a well has become increasingly important as a keyoperational parameter for many operators.
Key features• Compact design, consists of a pipe spool and an
Exd flow computer mounted typically upstream of the multiphase meter
• Stand-alone product based on modularity, allowing integration with both new and existing multiphase meters
• Real-time continuous outputs of both water conductivity and salinity
• Low uncertainty and large operating range
Roxar Multiphase Salinity System - A new innovation from Roxar, thepioneer in multiphase flow metering
Added Value for Customer• Salinity independent multiphase measurement • Formation water detection and break-through
monitoring• Flow assurance, e.g. optimise corrosion,
erosion and scale inhibitors• Reservoir management purposes e.g. maximise oil
production /minimise water coning• Injected water monitoring
With the introduction of this product to the Roxar portfolio, for those applications which demand high accuracy, or are experiencing high watercuts and unstable salinity, Roxar are able to offer the RMSS as a solution to support and enhance the multiphase measurement achieved by the Roxar Multiphase meter.
