Sealing/Packing TRIZ Cases
- High-Expansion Bridge Plug Setting Tool Wireline Core Bit
A step-up gearbox setting tool expands a bridge plug through a core bit, eliminating multiple drill rod trips and reducing formation damage risk.
- Corrodible Wellbore Plug Dissolution via Reservoir Fluids
Corrodible wellbore plugs dissolve in corrosive reservoir fluids, eliminating costly drill-out processes and preserving well integrity during deep operations.
- Wellhead Orientation Sensor for Tubing Hanger Alignment
Gyro sensor measures landing string rotation to prevent misalignment and costly reinstallation during deepwater wellhead operations.
- Nested Cylinder Compact Blowout Preventer Design
A compact blowout preventer uses nested cylinder actuators to generate high sealing force within a reduced outer diameter envelope.
- Well Tool Anchoring Device With Serrated Link Elements
Pivotable serrated link elements expand radially to anchor the tool, preventing upward movement of the heat generating mixture.
- Modular Wellbore Recovery System for Offshore Operations
A modular wellbore system uses a hydraulic latch piston to unlock and retrieve downhole components via wireline.
- Downhole Setting Tool Impact Dampening with Polyurethane Foam
Polyurethane foam composite absorbs shock energy in downhole setting tools without hydraulic fluids.
- Downhole Packer Ring Assembly Using Elastic Deformation
Downhole packer ring eliminates time-consuming set screw assembly by using elastic deformation of end tabs to provide uniform gripping force on the basepipe.
- Expandable Backup Rings for Downhole Bridge Plug Sealing
Spiral-slotted backup rings expand radially under axial force to seal the annular space, preventing fluid leakage in well casing operations.
- Swellable Packer Seal Element Using Gas-Responsive Polymer
Gas-responsive polymer seals expand upon hydrocarbon contact, replacing complex mechanical actuators for retrievable isolation.
- Installable Shoulder Segments for Tubing Head Component Retrieval
Segmented shoulder rings assemble within tubing head bores to support wellhead components and enable internal access.
