Sealing/Packing TRIZ Cases

Eliminates permanent stop shoulder to maintain full bore access and reduce housing material usage

A wellbore isolation device uses a dissolvable anode and electrolytic compound to enable chemical dissolution of the metal structure.

An accumulator system supplies fluid pressure to actuate a setting tool via a spoolable line.

A setting and retrieval sleeve disengages an engagement member from a body lock ring to release trapped energy in downhole tools.

A blowout preventer monitor uses magnets to couple plates and detect ram position via a trigger sensor.

Helical milling extracts permeable cement from the annular space, eliminating fluid migration pathways and restoring well isolation integrity.

Radial expansion of the elastomeric seal wall resolves transport and installation constraints while maintaining structural integrity.

An overshot sleeve swivel converts torque to axial motion, eliminating separate disconnection tools and reducing contamination risks during wellbore operations.

Nested deformable members stretch over each other to accommodate varying casing diameters, ensuring reliable fluid tightness across different well operations.

A packer assembly uses a movable piston and collapsible locking member to set and unset the device in one trip.

A soluble metal bridge plug uses a metal sealing ring to provide hard sealing at the wedge and slip junction.

Differential pressure drives a cementing tool sleeve to open flow ports, eliminating plug removal steps and reducing operational complexity.

Thermal stimulation transforms a protected cylindrical cup into a sealing shape, preventing abrasion damage during installation in deviated wellbores.

A tubing hanger running tool integrates a pressure equalization system with an internal accumulator to maintain hydraulic control without external umbilical lines.

Mediator adapter with localized engagement members secures slip hangers, eliminating damage risks during retrieval operations.

Segmented wellhead assemblies allow closing master valves without severing injection tubing, reducing workover rig costs.

A degradable landing collar body weakens upon fluid exposure to enable removal.

Grain-like solids anchor a wellbore plug by translating axial force into radial friction, resisting slippage under high pressure.

Universal packer design accommodates non-standard threads without adapters, ensuring reliable wellbore sealing.

Segmented expandable sleeve increases collapse rating without raising expansion pressure for high drawdown wellbores.

Pseudo direct drive motors replace hydraulic cylinders to eliminate fluid leaks and improve ram position precision.

A pressure regulating branch diverts coolant flow to reduce pump stress caused by high dielectric oil viscosity at low temperatures.

An adjustable packing element assembly uses an expandable ring and sleeve to match varying casing diameters.
