Geophysics Downhole

1. Spontaneous Potential (SP) - electrical potential between borehole and formation fluids
2. Single Point Resistance (SPR) - resistance of rock, saturating fluid, and borehole fluid
3. 8", 16", 32", 64" Normal Resistivity - resistivity, in ohm-meters of rocks and saturating fluids
4. EM Induction (Conductivity) - conductivity of rock and saturating fluids
5. Natural Gamma - total gamma radiation from natural or artificial radioisotopes
6. Spectral Gamma - spectral gamma radiation from natural or artificial radioisotopes
7. Density - total electron density
8. Neutron - hydrogen content, elemental spectra
9. Full Waveform Sonic - compressional, shear, and tube wave velocities
10. Acoustic Televiewer (ATV) - acoustic reflectivity of borehole wall, borehole geometry and deviation
11. 3-Arm Caliper - hole or casing diameter and rugosity
12. Fluid Temperature and Resistivity - temperature and resistivity of fluid near sensor
13. Fluid Sampler - takes up to 1.5 liters of fluid at point-specific depths
14. Spinner Flow Meter (FLP-2492) - velocity of net flow in borehole
15. Borehole Deviation - inclination and bearing of borehole
