Wells & Subsurface

Lifecycle Wells Expertise

Our wells and subsurface teams support the lifecycle of wells, from early subsurface evaluation and well design through operations, integrity management and end-of-life plugging and abandonment.

Integration drives value and we can provide specialist support or take full responsibility for well operations. By assuming greater responsibility we can share risk, limit your liabilities, and ensure wells are designed, operated, and closed safely and compliantly.

We deliver:

  • Subsurface studies and field evaluation
  • Well completion design and engineering
  • Well construction and operational management
  • Well integrity monitoring and intervention
  • Plugging and abandonment programs
  • Integrated, multi-well decommissioning delivery

Well Decommissioning

Through our well operator, engineering, and decommissioning projects, we understand the issues for wells approaching end of life. We offer a fit-for-purpose, asset-led approach to each project, supporting discrete studies, integrated service packages, or complete turnkey solutions.

We are the only contractor globally who can deliver decommissioning and well plugging and abandonment under a fully managed model – from working with customers to create initial methodologies to well plugging and abandonment, disconnection, dismantlement, and onshore breakdown.

And by leveraging our core capabilities developed in oil and gas, we are also ready to support emerging carbon capture and storage projects, where the re-use of existing assets, wells and reservoirs offer new opportunities.
