Sealing/Packing TRIZ Cases

Modular ram change assemblies let blowout preventer bonnets and rams move quickly for easier maintenance and reliable open-close transitions.

Arc arms and a compressed packer stack deploy a cup seal that conforms to irregular wellbores for uniform zone isolation and less cross-flow.

A retrofit pressure intensifier boosts bridge plug setting force through hydraulic amplification, avoiding costly DPU redesigns.

A thermoplastic deformable spacer expands against the tubing string to cut sealing-element strain and prevent fluid bypass in HTHP wells.

A segmented wellhead connector uses tapered fasteners and seals to handle high pressure while allowing stuck casing disassembly without internal cutters.

Downhole plugs, fluid-driven jarring, and internal severance free stuck wellbore tubing while avoiding pressure damage from surface cutting.

A layered metal alloy and cement seal repairs casing-annulus leaks while resisting pressure, temperature shifts, channeling, and creep.

An anti-rotation key and sleeve assembly helps downhole plugs set evenly, maintain a gas-tight V0 seal, and stay drillable in high-temperature wells.

Automatic load-triggered gear shifting moves BOP rams quickly, then boosts force to shear tubulars within tight API time limits.

A segmented anti-extrusion ring shields the spring from contamination, preserves packer seal integrity, and keeps components retrievable under high pressure.

Sensors inside the blowout preventer track ram position and trigger rig shutdown to prevent drill string and component damage.

A hollow bridge plug and sealed cement bailer place cement without blocking the flowpath, preserving logging and production access after water shut-off.

A slotted load ring expands by bending against the wellbore wall to improve horizontal well sealing and gripping without elastomer extrusion.

Interdigitated barrier walls create a tortuous path that expels debris from rotary seals, delaying lubricant contamination and bearing wear.

A floating piston and actuator sleeve move the locking dog remotely, securing leak-tight subsea connections with stable long-term engagement.
