Flow Assurance


Flow assurance—ensuring the successful and economical flow of hydrocarbons from the reservoir to the point of sale—is vital to successful long-term operations. 

Weatherford Laboratories’ suite of reservoir fluid analysis techniques is designed to identify the various components of reservoir fluid which threaten flow assurance. This is dynamic testing protocol that constantly evolves as more information becomes available. Testing continues to be honed until we are satisfied that the analysis will yield the best and most cost-effective flow assurance solution.

Threats to flow assurance include a diverse set of components in the fluid that may deposit on the internal walls of piping and process equipment, under the right conditions of temperature and pressure, to slow or ultimately
stop flow.

The deposition of solid particulates such as asphaltenes, wax/paraffins, and scale can quickly hinder production from a well and require costly and time-consuming intervention methods to remedy. Weatherford Laboratories employs a suite of solids deposition screening tests to evaluate the potential for these solids to form, and then suggest the appropriate mitigation strategy to keep production flowing and avoid an intervention. Current capabilities include:

  • BS&W

  • Asphaltene screening

  • Asphaltene onset pressure (AOP)/ Asphaltene deposition envelope (ADE)

  • Wax deposition and wax appearance temperature (WAT)

  • Scaling/asphaltene tests using tube blocking techniques

  • HP/HT solids onset (NIR or laser) system with HP microscope

A thorough understanding of the composition and phase behavior of reservoir fluids is an important parameter in managing the flow assurance program for any field.

As reservoir fluids from different sections of a reservoir (or from different wells) commingle, it is vitally important to understand the interaction between fluid streams and any potential flow assurance risks to the production system. Weatherford Laboratories has the tools and analytical expertise to analyze fluid streams at a fundamental level and their potential for scale, corrosion, asphaltene deposition, or hydrate formation.

The formation of natural gas hydrates is a pervasive problem in deep and ultra-deep water fields and can quickly plug off a pipeline or riser if left untreated.

Weatherford Laboratories fluid analysis toolkit includes a suite of hydrate formation tests to identify hydrate formation potential and suggest proper mitigation methods, including hydrate-stirred autoclave cells.

We work with our clients to understand the specific flow assurance problems they want to solve. From there, we tailor a customized flow assurance test protocol to address their challenges.
