Electric/Magnetic Detection For Well-Logging TRIZ Cases
- Cryogen-Free Cryostat for MRI Hyperpolarized Sample Preparation
A vacuum-insulated cryostat enables MRI hyperpolarization without cryogen handling while limiting polarization loss during sample melting.
- Slotted Point Dipole Antennas for Accurate LWD Resistivity
Closed-loop slotted dipoles with ferrite rods improve LWD resistivity antenna efficiency and modeling accuracy while reducing induced current effects.
- Directional Borehole Earthing with Real-Time Resistance Monitoring
Real-time resistance monitoring during directional drilling guides earthing electrode placement into lower-resistivity ground with less excavation.
