Reduced Diameter Neutron and Density Tools

Product Information

A popular version of reduced diameter neutron and density sondes is also available. These sondes offer the advantage of having a slimmer diameter, making them suitable for reduced diameter boreholes.

They also require smaller radioactive sources. However, they are only suitable for qualitative porosity or density measurements because they do not lend themselves to easy or effective calibration.

38mm Trisonde (2pi gamma-gamma probe) – bottom loading

  • Provides qualitative formation density readings in cps
  • Uses a 10mCi Cz-137 radioactive source – this is a smaller and weaker source then the standard density probe
  • Combinable with other Geovista probes (bottom of tool string)
  • Commonly used for logging coal seams (in open and cased holes)
  • Smaller diameter then the sidewall formation density sonde – can be run inside drill-pipe
  • The sonde has three detectors (short, long and natural background detector)

46mm Trisonde (2pi gamma-gamma probe) – side loading

  • Provides qualitative formation density readings in cps
  • Uses a 10mCi Cz-137 radioactive source – this is a smaller and weaker source then the standard density probe
  • Combinable with other Geovista probes (in-line so you can connect probes above and below this probe)
  • Commonly used for logging coal seams (in open and cased holes)
  • Smaller diameter then the Sidewall Formation Density sonde – can be run inside drill-pipe
  • The sonde has two detectors (short and long detectors)

38mm Neutron-Neutron probe – bottom loading

  • Provides qualitative formation porosity readings in cps
  • Uses a 10mCi Am-Be radioactive source – this is a smaller and weaker source then the standard Dual Neutron probe
  • Combinable with other Geovista probes (bottom of tool string)
  • Smaller diameter then the Dual Neutron sonde – can be run inside drill-pipe
