Constructions TRIZ Cases
- Slidable Isolation Sleeve With I-Shaped Seal for Multilateral Wellbores
An I-shaped seal on a sliding sleeve isolates secondary wellbores from high-pressure fluids, protecting existing equipment during stimulation.
- Dual Flapper Valve for Reverse Cementing
A dual flapper valve shifts positions to direct cement slurry into the annulus without inner tubing.
- Interchangeable Module for Integrated Perforating Gun Assembly
An interchangeable module simplifies assembly by replacing specialized components with a single unit that reduces logistical complexity.
- Shield Machine Excavator With Swinging Cutter Head
A shield machine excavator uses a swinging rotary cutter head to adapt excavation contours.
- Shock-Absorbing Sleeve for Downhole Tools
A shock-absorbing sleeve uses pressurized dampening fluid to control axial movement speed.
- Flexible Borehole Liner with Segmented Carbon Strips for Fracture Flow Detection
A flexible liner impregnated with a tracer substance uses segmented activated carbon strips to adsorb leached material from flowing water.
- Passive Acoustic Array for Wellbore Sand Detection
Passive acoustic array detects sand movement via model-based feature extraction, preventing infrastructure erosion from uncontrolled production.
- Subsurface Safety Valve Locking Tool Prevents Uncommanded Closure
A locking tool with a protrusion abuts the fishneck to mechanically hold the subsurface safety valve open during wireline operations.
- Drill Head Wireless Transmitter Antenna Placement
A drill head wireless transmitter antenna placement strategy minimizes eddy current losses within the conductive housing during operation.
- Field Deployable Clumped Isotope Analysis System
Replaces time-consuming wireline sampling with real-time spectroscopic analysis to distinguish reservoir compartments.
- Photomultiplier Dynode Ring Structure for Electron Collection
A photomultiplier uses conductive outer and inner rings on dynodes to shape electric fields.
- Dry Drilling Dust Extraction with Rotary Lobe Blower
Rotary lobe blowers maintain stable volume flow during dry drilling, preventing pressure drop disruptions while cyclones separate coarse cuttings.
- Moisture Sensor Groundwater Detection in Rock Drill Cuttings
Moisture sensors analyze rock cuttings to map groundwater locations, reducing unnecessary explosives and grouting costs.
