ONS 2024: SLB releases well integrity assessment tool for carbon storage developers

SLB has released a well integrity assessment technology that assists carbon storage developers quantify the risks associated with wells at prospective storage sites with previous drilling activity.

The company says its new methodology for quantifying the probability and potential impact of carbon leakage helps users understand the risks associated with each well, informing remediation strategies and ultimately estimating the project's long-term viability.

“The significance of the risks associated with each well and the costs of remediation to mitigate leakage risks can make a project economically unfeasible,” said Frederik Majkut, SLB's senior vice president of Industrial Decarbonization. “By addressing potential well integrity issues early in the development process, SLB’s well integrity assessment solution can help storage developers avoid costly delays or operational disruptions, and drive companies toward their net zero ambitions.”

Many prospective carbon storage sites are located in either mature or retired oil and gas fields, and having a large number of wells at a site can increase the risk of potential leakage pathways for the stored carbon.

The well integrity assessment technology incorporates advanced failure mode effect and criticality analysis to assess potential leakage pathways, well barrier, failure mechanisms and resulting consequences. Utilizing multi-physics 3D modeling, SLB says it can assess the volume and flow rates of brine and carbon leakage over time to better estimate risk.

SLB is exhibiting this week at booth 8150 at ONS 2024 in Stavanger.
