Two sets of detectors are positioned around a removable AmBe neutron source and housed in a 43mm OD down hole logging assembly called a Quad Neutron Tool (QNT), or “Quad”. Also in the Quad tool string are several supporting detectors. These include: Natural Gamma Ray, Split Spectrum Gamma Ray, CCL, Top and Bottom Temperature, Fluid Resistivity, and an Accelerometer.  The Quad data bus and modular connector configuration enables attachment of many other detectors to be accommodated for specific applications.

Quad Neutron tool is used on high risk horizontal new drills and can log through drill pipe, case and then log. It’s also a great tool for cased reservoir management wells and can identify areas with high water saturation and bypassed hydrocarbon. Applications for shale oil and gas formations, formation water salinity determination and fracture planning and evaluation can also be done with this tool.[/vc_column_text][vc_empty_space height=”25px”][vc_empty_space height=”25px”][vc_column_text css_animation=”fadeInUp”]

The standard log presentation is the Quad Litho Log and below are just some of the interpretable parameters:


  • Porosity including clay free porosity.
  • Saturation including the ability to differentiate between fresh water and heavy oil.
  • Clay Volume.
  • Relative Permeability.
  • Relative Bulk Density.
  • Dolomite identification in carbonate reservoirs.
  • Pyrite and calcite identification in clastic formations.
  • Differentiation between bitumen and moveable oil.
