Enabling offshore carbon storage through data-led well testing

Accelerating offshore well testing to meet carbon capture, CO₂ storage, and net-zero targets

From first appraisal to full-scale deployment, Expro is setting new standards for CCS well testing – delivering certainty to permanently store CO₂.

Carbon capture and storage (CCS) is essential to achieving UK and European net-zero targets. The Northern Endurance Partnership (NEP) is a flagship North Sea CCS project, designed to transport and permanently store CO₂ offshore. It supports the country’s ambition to store up to 50 million tonnes of CO₂ annually.

Expro has been selected to deliver integrated offshore well testing services for the project, supporting appraisal of the Endurance reservoir for long-term CO₂ storage. Using our deep well flow management and subsea well access expertise, we’re enabling operators to gather high-quality data on reservoir performance, fluid behavior, and storage integrity. Our data-driven approach reduces uncertainty, accelerates project timelines, and ensures safe and reliable CO₂ injection and storage.

Building on our unrivalled CCS credentials, particularly in the North Sea with projects including Northern Lights and Smeaheia with Equinor, Havstjerne for Harbour Energy, and planned well tests in Denmark, we’re empowering faster, more informed decisions to advance carbon capture, offshore CO₂ storage, and CCS infrastructure.

From first appraisal to full-scale deployment, Expro is setting a new standard for CCS well testing – delivering the certainty to permanently lock away CO₂.
