Carbon Capture and Storage

Safe well re-entry and abandonment for CO2 storage applications

LEGACY WELL RE-ENTRY AND TIEBACK SOLUTIONS

Key to carbon capture and storage is the integrity of the formation/reservoir that the CO2 will be stored within.

Whilst legacy oil and gas fields are considered good carbon capture and storage locations, given the proven formation properties and existing pipeline and platform infrastructure, a key risk and liability is the remaining suspended, or abandoned legacy wells. These legacy wells may have been abandoned correctly at the end of the field’s life, but barrier selection and testing may not be suitable for underground CO2 storage applications. A field that would otherwise be the perfect carbon capture and storage location could be discounted due to CO2 integrity concerns, or even need a costly relief or intersection well drilled to correctly plug and abandon the legacy well and ensure it's secure.

 

At Aquaterra Energy our field-proven well re-entry and tieback engineering products and services can help carbon capture and storage projects eliminate issues such as these.

Our track record of successfully planning, engineering, and re-entering suspended, or abandoned wells is second to none, with over 500 wells engaged and over 100 years of combined in-house experience.

We understand that every well re-entry has its own unique challenges; such as lack of well data, damaged tieback connectors, cut or below mudline connectors, and well integrity issues to name a few. But with careful planning, access to our large inventory of riser systems and tieback tools and equipment and, where necessary, design and manufacture of bespoke well specific primary and contingency equipment, even the most problematic legacy wells can be safely re-entered and abandoned to suit carbon capture and storage applications.

To find out more about how our well re-entry and tieback engineering services can support your carbon capture and storage projects eliminate issues associated with legacy wells, get in touch.
