ScaleChek

Wood Group Production Technologyrovides continuous, real time monitoring and analysis. Fluctuations in the ionic concentrations are measured by the surface acquisition unit. When installed in conjunction with a Scale Management System, ScaleChek will control the chemical pump dosage. The sensing is passive, i.e. no sampling process or intervention is required.

The sensing employs a potentiometric principle where the potential difference between two electrodes is measured. Any changes in hydrogen ion or chloride ion concentrations will give a corresponding change in the potential difference.
Benefits
• Early detection of calcium carbonate scale
• Chemical injection treatment optimised
• Early detection of water influx
• Deferred oil minimised
• Interventions reduced
• Production increased
Features
• Realtime sensing and analysis
• Non-intrusive to production bore
• Can be deployed at surface or downhole
• Self cleaning sensor

The ScaleChek downhole hardware configuration is practically identical to that of a standard dual P&T configuration. The P&T gauge and the pH/CI gauge are multi-dropped off a single 1/4" electric cable. The gauges are housed in a mandrel that form part of the tubing string.
