Survey TRIZ Cases
- Water Hammer Analysis for Wellbore Friction Loss Determination
Induce tube waves to measure pressure changes at the wellhead, determining pipe and perforation friction without downhole sensors.
- Mud Gas Separator Weight Monitoring for Drilling Fluid Gain Detection
A mud gas separator tracks internal weight to identify fluid gain or loss events during drilling operations.
- Acoustic Telemetry with Distributed Acoustic Sensing
Distributed acoustic sensing detects strain in optical fiber caused by downhole acoustic signals.
- Closed Loop Model Predictive Control for Directional Drilling
Model predictive control compensates for feedback delays by predicting future drilling attitudes, eliminating oscillations and preventing borehole spiraling.
- Double-Studded Pack-Off Adapter for Fracking Pressure Differentials
Integrated double-studded pack-off adapter joins lower-pressure wellhead casings to high-pressure fracking assemblies via multiple sealing interfaces.
- Acoustic Core Sample Testing with Elastic Pressure Cell
Segmented sample chamber and elastic membrane apply uniform confining pressure to maintain consistent transducer contact during acoustic velocity measurement.
- Piezoelectric Transducer Fluid Isolation Diaphragm
A diaphragm isolates the sensor from conductive borehole fluids, preventing impedance errors while measuring sound speed.
- Integrated Fuel, Power, and Comms Cable Assembly for Fracturing Units
Merging fuel delivery, power supply, and data connections into one assembly reduces setup time and complexity for hydraulic fracturing operations.
- Low Density Gas Hydrate Inhibitor Formulation
Lithium chloride and glycol ether blends inhibit downhole hydrates while maintaining fluid density between 1.08 and 1.3 gm/cm3.
