Comprehensive Decommissioning Solutions

Decommissioning is a critical phase in a well’s lifecycle, requiring detailed planning, innovative technologies, and cost efficient execution. Well Engineering Group offers expertise in:

Well Decommissioning Basis of Design
Collaborating with subsurface teams to develop tailored well decommissioning strategies based on geological and geophysical assessments.

P&A Design and Planning
Full well decomissioning project lifecycle management (or part thereof as required), including optimised P&A design, regulatory permissioning and compliance and full project planning for execution readiness. 

Pre-Rig Campaigns
Executing pre-rig activities from platforms and intervention barges in order to de-risk and lower the cost of rig-based P&A operations.

Plug & Abandonment (P&A) Operations
Managing the safe abandonment of open water wells, subsea wells (from jack-ups), platform wells, and subsea development/exploration wells.

Advanced P&A Techniques
Deploying casing cut and recovery tools, conventional cementing, Perforate Wash & Cement (PWC), section milling, multi-string annluar barrier/cement assurance, and alternative barrier material (e.g. Bismuth alloy) plug installations for secure well abandonment.

Complex Well Re-Entry
Developing bespoke solutions for safely and efficiently re-entering wells with degraded barriers or legacy wells with aged or damaged/removed wellheads etc.

Swarf Recovery & Conductor Removal
Installing swarf recovery systems on jack-ups and semi-submersibles, and performing pin and bore operations for conductor recovery on jackets.

Decommissioning Cost Estimates & Liability Assurance
Providing detailed cost analysis and liability assessments to support financial planning and regulatory compliance.
