PVT & Flow Assurance


At HOT fluidXlab, we understand the unique challenges that energy companies face in today’s competitive market. We have designed our solutions to provide innovative, reliable and HSE-compliant fluid testing services. This allows us to meet the requirements of even the most challenging projects (CCS, CCU, hydrogen).

WHY CHOOSE fluidXlab?

We specialise in fast and accurate PVT (pressure-volume-temperature) and fluid analysis, helping engineers understand fluid behaviour at different scales. By leveraging our technologies and expertise, we can draw valuable conclusions from the results that can support you in optimising your operations.

All laboratory experiments are being conducted in compliance with the strictest HSE regulations using fluids and diverse gas mixtures including hydrogen, carbon dioxide and hydrocarbons in extreme conditions (under high pressure and in extreme temperatures).

Key Benefits of our fluid
testing services

Our PVT and fluid analysis solutions are designed to deliver the most accurate and reliable results, allowing you to make informed decisions and stay ahead of the competition. The benefits for the oil & gas and Energy companies include:

Robust Workflows
at scale
