Platform & subsea well life extension

2H Offshore - Platform and Subsea Well Life Extension

2H provides clients with detailed assessments of a subsea well’s current condition and potential future use to determine if life extension is possible.

Life extension of subsea wells is proving to be a cost-effective method of maximising production in fields that are aging and possibly approaching the end of their design life.

The assessments conducted by 2H consider the asset’s operational history since installation and detail its residual strength and fatigue capacity to help decision making regarding re-entry. To achieve this, 2H works closely with clients to gather as much data as possible on the well’s operational history, including as-built design records and surveys detailing any degradation.

2H then defines and delivers a scope of work that is appropriate to the specific well. The outcomes of the assessment are used to define guidelines and recommendations for the planned operations, which may include the use of structural monitoring or in extreme cases, wellhead load relief systems.
