Providing the full well performance picture

We are experts in well integrity evaluation with three decades of experience, delivering the best solutions and helping global operators and service partners overcome their well challenges.

Well integrity evaluation means getting the full picture of your well’s barrier performance. Our expertise will help you understand the structural integrity of tubing, casing, liners, and cement. By employing cutting-edge downhole tools and logging services, we provide precise identification and quantification of issues such as damage, deformation, leaks, and scale build-up.

Whether deploying electric wireline, slickline, or coiled tubing in memory or real-time, our well intervention services are tailored to suit your specific requirements and operational needs.

We optimise the performance and longevity across your well’s lifecycle.

Our industry knowledge, technical excellence and proven track record provide the answers to help you with:
