COMPLEX RESERVOIRS. EXECUTION-READY ENGINEERING.
A three-zone development well required a well architecture and completion design that could accommodate significant overpressure in the deepest zone.
- Full casing architecture, liner design and load-case checks
- Torque and drag analysis for liner rotation during cementing
- Cementing programme and spacer optimization
- Dual-string completion architecture
- Two-barrier philosophy with pressure tests, leak-off validation and safety-valve verification
- Directional targeting and a detailed engineering risk register
The resulting well programme addressed pressure containment, cement integrity, connection torque limits and ongoing annulus monitoring.
