Fluid Removal TRIZ Cases
- 3D Hybrid Grid Generation for Reservoir Simulation
A 3D hybrid grid generation method combines structured and unstructured zones to model heterogeneous formations.
- Refracturing Borehole Isolators for Thermal Shift Alignment
Bottom hole assembly isolators position offset from existing perforations to enable new perforation through the sealing device.
- Pressure Set Liner Hanger Without Tubing Wall Ports
A pressure-set liner hanger uses a movable setting sleeve to sequentially deploy slips and packer seals via hydraulic pressure.
- Horizontal Wellbore Vertical Inclusion Propagation for Heavy Oil Drainage
Vertical inclusions propagate from horizontal wellbores to create permeable drainage planes, addressing low heavy oil mobility in unconsolidated formations.
- Vitrified Glass Spheres from Waste Metabasalt
Transforming depleted high-grade sand scarcity by converting waste metabasalt into vitrified glass spheres with enhanced fracture toughness.
- Oriented Flow-Through Passages for Sequential Wellbore Fracturing
Orienting flow-through passages creates varying fracture initiation pressures across multiple wellbore zones, eliminating sequential equipment repositioning.
- Expandable Sleeves for Hydraulic Stimulation Zone Isolation
Expandable tubular sleeves mechanically seal against well casings to isolate stimulation zones.
- Recovery Valve Shear Ring for THRT Retrieval
A recovery valve uses a shearable ring to unlock tubing hanger running tools via hydraulic pressure shifts.
