Flushing TRIZ Cases
- Dual Drill String Actuator Valve Design
Segmented barrier valves prevent gas-kicks by closing internal and external flow paths without excessive complexity.
- Electrically Triggered Lost Circulation Material for Wellbore Plugging
An electrically activated lost circulation material system uses downhole electrodes to solidify electrorheological fluids into a gel plug.
- Subsea Landing String Autonomous Emergency Shut-In
An instrumentation module monitors tension to autonomously trigger emergency shut-in, preventing hydrocarbon release during overpull events.
- Ultrasonic Slip Velocity Measurement for Drill Cuttings
An ultrasonic device measures fluid levels in a narrow tube to determine drill cuttings slip velocity.
- Solid State Lost Circulation Material for Drilling
Expandable polymer layer hardens to seal lost circulation zones, eliminating cement setting delays.
- Fast Pressure Protection System for Wellbore Servicing
A pressure control system with a relief path and fast-acting valve dissipates excessive pressures within 0.10 seconds to prevent equipment damage.
- Magnetic Debris Collecting Tool for Drilling Fluid
Nested magnetic collectors remove debris from the drill string flow path to protect downhole components.
