- Subsea Sampling
At-source production chemistry
Knowing the chemistry of fluids and solids inside the pipeline allows you to calibrate subsea multi-phase flow meters, assists in efforts to reduce production losses and supports the unrestricted flow of fluids from reservoir to refinery.
Proserv has been engineering and designing equipment for sampling subsea for over 15 years.
Understanding the chemistry
Operators are required to conduct analytical testing for a variety of reasons. This includes establishing a value, a concentration profile or determining local contamination. What is sampled, and the way samples are taken will impact the reason for the analysis. As a result, the significance of the sampling stage cannot be overstated. If the sample is not representative of the original material, it will not be possible to relate the analytical result measured to the original material, no matter how good the analytical method is or how carefully the analysis is performed.
Proserv works in partnership with clients to design, build, maintain and operate a range of subsea sampling systems to allow for representative sampling. We specialise in delivering solutions for remotely operated vehicle (ROV) and diver sampling systems, allowing for the capture of representative samples from the subsea tree, pipeline or manifold. We provide solutions that support umbilical controls, decommissioning, chemical injection, flow assurance issues, and metering and allocation.
Based on market-leading sampling technology, our subsea sampling cylinder (SSC) is designed and qualified specifically for use in the harsh environments experienced subsea. In addition, the Proserv SSC is certified for shipping, under PED & DOT, therefore eliminating the risks associated with handling and transferring samples to transportation containers. Designed to meet the stringent requirements of NACE, API-6A and API-17D, Proserv’s subsea sampling system specification can be customised as required to meet the client’s needs. Our rental units are available for rapid deployment.
The benefit of using the right sampling method is to obtain the right data. Sampling allows an opinion to be derived through enhanced understanding of the chemistry at source. Subsea sampling can provide a range of insights on the following:
