Constructions TRIZ Cases

Radial expansion of the seal assembly allows oversized tools to pass through, resolving damage risks from proppant and tool passages.

Stationary and moving acoustic sensors capture leak signals to generate multi-dimensional probability maps for precise wellbore defect localization.

Shear pins retain an open valve member until flow exceeds a threshold, shearing to close the plug and enabling replacement gun deployment.

A segmented drive pin assembly with a guiding bushing prevents shear pin bending and burr formation during tool actuation.

Pleated rings and heated asphaltic sealant create a metal-to-metal seal that prevents micro-annulus formation and fluid leakage.

A machine learning system selects optimal logging deployment options by analyzing well, mud, and tool configuration data.

Anti-extrusion ring protects elastomer from high pressure while garter spring spans the gap, enabling reliable sealing and easy retrieval.

Sliding sleeves use ball-engaged inserts to open ports, allowing multiple zone treatments with one tubing string while buttons maintain pressure.

A dual flapper isolation valve uses independently actuated upper and lower sub-assemblies to maintain a slim outer diameter.

A gas-tight shaker uses diluent to separate oil-based mud from drill cuttings.

A reverse stage cementing sub uses a pressure-actuated flapper valve to control fluid flow between the annulus and casing string.

A circulating sleeve provides an internal return path for fluid within an expandable liner hanger assembly.

Dissociated methane creates buoyancy to lift well fluids, eliminating submersible pumps and preventing hydrate blockages.

A rotodynamic pump drives multiphase fluid through a series conduit, enabling flow rate calculation from two pressure differentials and rotational speed.
