Well Integrity

Giving you the full picture of your well’s performance

Well Integrity

We are experts in well integrity evaluation. For 30 years we’ve been delivering solutions that help operators and service partners overcome their well challenges all over the world.

Well integrity evaluation means getting the full picture of your well’s barrier performance. It’s about understanding the structural integrity of your tubing, casing, liners and cement. Ultimately, this helps you manage risk, extend operating life and optimise the management of your wells across their lifecycle.

READ offers a range of specialist well integrity services, enhanced by value-adding technologies, for accurately identifying and quantifying damage and deformation, holes, leaks, corrosion and scale build-up, deployable on electric wireline, slickline or coiled tubing in memory and real-time.

Our solutions are tailored to your individual equipment and operations. Our know-how and expertise provide the answers to help with:
