Fluid characterisation

CMR has a long-standing tradition of developing measurement methods and equipment for the characterisation of fluid properties. Application areas range from Oil&Gas and aquaculture to environmental monitoring.

Fluid characterisation

CMR has developed a large variety of methods for characterising single- as well as multiphase fluids, based on acoustic, electromagnetic, gamma-ray, or optical sensors. Amongst others, the following properties can be used to characterise different fluids:

  • Density and permittivity of crude oil
  • Caloric value of hydrocarbon gas
  • Water salinity and salt composition
  • Water-to-liquid ratio
  • Dissolved carbon dioxide in water

These parameters might be used directly, or integrated into multimodal measurement systems. Along these lines, CMR has developed the Subsea Online Fluid Analyser (SOFA), a multimodal, in situ, in-line measurement system for multiphase hydrocarbon streams. The core idea of SOFA is to sample the fluid by diverting a small portion of it into an in-line separation chamber. Here, measurements are performed on the individual phases using acoustic, gamma-ray, and electromagnetic sensors, before the fluid sample is released back into the stream.
