“Our goal is to add value and wealth creation to operators, and support Maximising Economic Recovery with design, manufacture, and application of Subsea Sampling Systems, through provision of sound Engineering and Production Chemistry practices.”
Benefits • Trace heating on sample cylinders • Modular design for easier build & Maintenance • Real-time instrumentation for pressure and temperature • Visual indicators for accurate sample volume verification
Subsea Cylinder, 20000 psi, PED, DOT
Rented or PurchasedWith expertise in Production Chemistry & Engineering, we understand subsea sampling.
• Slops handling• System control & sensors• Sample collection cylinders
• Iso-thermal & iso-baric sampling• Phase biased sampling & enrichment• System deployment, connection & disconnection
Representative subsea sampling
Proserv specialises in delivering solutions for ROV and Diver Subsea Sampling Systems, allowing for the capture of samples from the subsea tree, pipeline or manifold.
Based on market-leading sampling technology, our Subsea Sampling Cylinders are designed and qualified specifically for use in the harsh environments experienced subsea.
In addition, the Proserv SSC is certified for shipping, therefore eliminates the risks associated with handling and transferring sample
Operational Benefits Upstream of Manifold• Easier to obtain a chemical free sample • Improved modeling of system dynamics • Removes necessity for production deferment • Nearer to source of fluids without expense of well
intervention • Undiluted, a more representative sample, less
doubt over validity of results • Reduces requirement for back-out calculations,
second-guessing flow rates• Potentially upstream of deposition, therefore
provides a sample in ideal condition
Cleanliness Benefits at Point of Source• Reduces risk of environmental release to sea • Provide reassurance to regulatory of system
condition • Increases confidence in control fluid and umbilical
condition
Wealth creation
• Removes the potential of working on the wrong solution
• Production uptime is sustained for longer, resulting in increased revenue
• Better data, leads to improved reservoir management and production optimisation

Diver Case Study
Project Background A UK independent oil producer commissioned Proserv to design, manufacture and supply a subsea sampling system capable of capturing reservoir fluid samples at temperature from subsea Christmas trees to support their operations.
SolutionThe project formally kicked off in March 2017 and a project delivery team was established involving design engineers, project managers, planners, buyers and technicians, who all worked closely to deliver this project to exact design specification.
The diver operated system was designed to meet the following requirements:
• 2 x 2 Litre Slops Cylinders • 6 x 2 Litre Sample Cylinders • Compact design to interface with Christmas Tree• Water depth of 100 meters and a pressure rating of 1000 psi minimum • Isothermal sampling - circulation of hot water within skid to
reduce risk of wax and hydrate formation
The completed subsea sampling system was fabricated, assembled, tested and shipped from our sampling and injection solutions facility in Aberdeen within 11 days of official call off.
Summary The full sampling process was completed within 24hrs. Subsea verification confirmed estimated sample volumes and allowed the client to sign off prior to equipment removal from subsea. Once the skid was returned to surface the sample cylinders were isolated, removed from the skid and sent to a laboratory for analysis.
to transportation containers, in doing so reducing the risk of containment loss and exposure to H2S / CO2, which can present a danger to people and the environment.
Benefits • Easy to use Diver interface• Variable sample and slops volume capacity • Closed Loop design for zero discharge to sea • Isothermal and Isobaric sampling capabilities• Ability to back flush / chemical injection to clean lines
