Seismic Data Acquisition TRIZ Cases
- Seismic Interferometry Ground Roll Attenuation Using Derivative Sensors
Derivative sensors measure particle velocity and spatial derivatives to estimate ground roll noise for seismic interferometry processing.
- Time-lapse Seismic Processing Using Kinematic Invariants
Kinematic invariants streamline seismic data processing by bypassing redundant velocity analysis steps, reducing duration for time-lapse reservoir monitoring.
- Variable Weight Dynamite Charges for Seismic Frequency Control
Applying periodic action to distribute unique charge weights expands the acquired frequency spectrum, improving stratigraphic reflector continuity.
- Marine Surveying Sound Source Positioning for Odd-Even Artefacts
Positioning the sound source between segmented sensor groups eliminates odd-even artefacts by ensuring full fold coverage at high speeds.
- Simultaneous Source Separation via Seismic Apparition
Deterministic time variations and random dithering encode simultaneous airgun sources, resolving interference that degrades separation accuracy.
- Unmanned Airborne Vehicle for Seismic Node Communication
An unmanned airborne vehicle accesses remote seismic sensor nodes via Wi-Fi and GNSS to harvest data and troubleshoot issues in challenging terrains.
- Marine Seismic Source Array Position Determination
Measures pressure fields at multiple locations to determine marine seismic source positions without external monitoring systems.
- Multi-firing Acoustic Source Dispersion Analysis for Shear Wave Slowness
Multi-firing acoustic sources generate waveform data for multi-mode dispersion analysis to determine formation shear wave slowness.
- Autonomous Seismic Source Control via Distributed Coordination
Distributed seismic energy sources operate independently using GPS synchronization and wireless communication protocols to resolve central system complexity.
