Proactive strategies are required to manage the impact of these solids on production and to maximise productivity. Solids production is typically episodic and can cause extreme damage almost instantaneously. The consequences can include reservoir damage, erosion of choke valves, erosion and accelerated corrosion of pipework, reduction of corrosion inhibitor performance and the filling of Separators: all resulting in reduced productivity. Reliable instantaneous management of solids in offshore and subsea systems is of vital importance. We offer state of the art measurement products and advocate an integrated measurement and control approach to solids management by providing directcorrelation tools between process measurement (volumetric flow and velocities, choke position, chemical inhibition-rates, pressure and temperature) and real-time intrusive erosion & corrosion measurement of particle impact effects. These are then linked to alarm management functions. This facilitates an instantaneous response to solids production thereby mitigating damage. The approach also provides the platform for the development of reliable empirical models/algorithms for the trending of the reservoir behaviour and establishing safe operational limits in terms of erosion damage. PTECTM range products provide options for Pressure, Temperature, Erosion or Corrosion measurement in a single probe (see data sheet CMEP023). Sand Erosion Probes can detect the minute quantities of material lost due to the erosion effects of the impact of entrained solids. The unique CEION® metal loss measurement technology has exceptional resolution and extended sensor life giving both high sensitivity to erosion and low cost of ownership. Field applications have documented the very high sensitivity of the probes to particles of all sizes, ensuring that low velocity fines for example, undetectable by acoustic methods, can be measured.
