Saturation Logging

Carbon Hydrogen Tool

FUNCTION

  • To evaluate the saturation of oil inside the well as a part for reservoir monitoring.

PRINCIPLE

  • Using the Pulsed Neutron principle with the measurement of Carbon Hydrogen Ratio (CHR)

Comparisons between C/H & C/O

Lab test in pure sandstone showing CHR influenced by oil saturation, barely influenced by porosity and mineralization
