Subsea Fluid Sampling to Maximise Value in Offshore Development

The acquisition of representative subsea fluid sampling from offshore field development asset is crucial for the correct evaluation of oil reserves and for the design of subsea production facilities. Due to rising operational expenditures, operators and manufacturers have been working hard to provide systems to enable cost effective subsea fluid sampling solutions. To achieve this, any system has to collect sufficient sample volumes to ensure statistically valid characterisation of the sampled fluids. Therefore, the combination of subsea MPFM, ROV deployed fluid sampling system and mechanistic compositional fluid tracking model has the potential to provide a balanced approach to reservoir performance monitoring. This provides an accurate method for validating individual production well test fluid samples. The subsea industry, particularly subsurface and surface engineers, will benefit from the mechanistic compositional fluid tracking model as a complimentary solution, to reduce cost of intervention for subsea sampling operations. With appropriate application of this mechanistic model, Enhanced Oil Recovery (EOR) can be realised on offshore field developments.
