The value of well testing at carbon storage sites

Carbon capture, utilisation, and storage (CCUS) is recognised as one of the pivotal enabling processes in the global transition towards reducing greenhouse gas emissions and achieving 2050 net-zero targets.

A previous article highlights the importance of CCUS in combatting emissions from the hydrocarbon industries and hard-to-abate sectors such as cement, steel or chemicals.

The International Energy Agency recognizes that while CCUS momentum is growing with over 500 projects in various stages globally, at this level CCUS deployment would remain well below what is required to reach net-zero by 2050.

For companies with a background in supporting the hydrocarbon sector, CCUS presents opportunities at various levels. As an example, leading provider of energy services Expro, which this year celebrates 50 years of supporting the North Sea energy sector, is advancing its industry-leading well testing expertise and capabilities into CCUS projects.

It delivered an integrated well testing solution for the flagship Northern Lights project in the Norwegian North Sea, where the data from the test provided critical contributions to the field development plan and final investment decision.

“CCUS is going to be key for the world to reach our climate change goals and Expro is establishing a successful track record in this emerging sector,” says Ingrid Huldal, director of sustainable energy solutions, Expro.

“It’s a great opportunity for Expro to bring all our 50 years of North Sea experience and expertise in well testing and well flow management, combined with our industry-leading technologies and services, to the development of CCUS projects regionally and globally,” she adds.

“Supporting CCUS is a natural evolution for us. Our technology is transferable, and we know many of the leading operators. From a just transition perspective, it supports job retention and fits well into our business strategy. It’s good for our communities and good for climate change.”

James Yard, CCUS development manager, Expro, agrees. “Detailed well testing will be critical in de-risking CO2 storage plans. Exploration and appraisal are common practices and well understood in the oil and gas industry.

“Appraising CO2 storage reservoirs, especially saline aquifers, will be equally important to characterise the pore space for CCS projects."
