Sealing/Packing TRIZ Cases

Non-reactive colloid particles no more than 500 nm fill expanded-metal interstitial spaces to limit gas migration in wellbore pressure-isolation tools.

Alloy beads travel through the cleaner tubular interior, then melt into a plug that repairs leaking downhole annular seals.

Dual topside controllers and subsea electronics manifolds switch communication modes instantly, reducing downtime from controller faults.

Moveable alignment tabs engage wellhead channels to orient hanger ports, prevent rotation, and reduce fluid-induced damage.

This case uses sealing material to stabilize annular control lines during orbital cutting, helping prevent leak paths in abandoned wells.

An expandable metal circlet uses mechanical and hydrolysis-driven expansion to limit wellbore leaks and axial slippage.

A stroke sleeve ratchets directly with the base, removing the independent lock ring to reduce backlash and manufacturing complexity.

Anti-rotation connectors keep the polymer sealing element anchored during drilling, helping remove the hybrid frac plug smoothly.

A signal interrupter confirms downhole plug setting without manual cable-tension checks.

A setting tool and pressurized fluid expand a tubular metal seal for reliable frac plug sealing in irregular downhole casing.

Inclined anchoring parts convert axial movement into radial force, preserving zonal isolation as temperature and pressure vary.

Circumferential inserts with ribs and pivoting feet trap elastomer during actuation, preserving high-pressure blowout preventer sealing.

This case shows how injected isocyanate-polyol grout expands into irregular wellbore voids before curing for durable fluid containment.

Two expandable sleeves and a thicker connector support thin-layer isolation while improving manufacture and axial load transfer.

This downhole completion case sequences annular barrier expansion so the middle barrier fully abuts the borehole before outer barriers.

This case uses an electronic actuator and shift mechanism to compress a BOP packer, improving sealing reliability in deep subsea wells.

This well-tool case uses a rotary-driven threaded sleeve to expand sealing elements while preventing axial set back.

Slots and buttons let a frac plug backup ring resist seal extrusion while supporting reliable anchoring and easier milling.

A rounded bull-nose contour and symmetric angles help blowout preventer ram blades shear and seal tubulars while resisting bending.

A pressure-controlled expandable sleeve adapts to varying wellbore diameters for targeted injection without restricting production tubing.
