Sealing/Packing TRIZ Cases
- Articulated Backup Resister for High-Pressure Well Seals
Articulated backup resisters expand under pressure to anchor against borehole walls, solving high-pressure seal failure.
- Angled Wing Bore Self-Draining Subsea Production Tree
Angled wing bores enable self-draining of hydrate-prone fluids during shut-in operations, preventing blockages without complex insulation.
- Mandrel Head Annular Sleeve Positioning for Wellhead Sealing
Positioning the threaded connection and O-rings below the seal pack prevents fluid leakage under high pressure while supporting external forces.
