The MPNN tool is a cost effective way to run pulsed neutron logs on slickline or coiled tubing. This short slim tool string can get in many wells where larger competing tools may have difficulty accessing the zones of interest.

Scientific Drilling’s MPNN tool is an innovative and durable design ensuring downhole reliability for applications such as gas/oil/water contacts, missed hydrocarbon zones, and time-lapse water saturation analysis.

The tool’s physics maintains statistical accuracy in low salinity formations, and is less dependent on the fluid type in the borehole to deliver accurate results. The MPNN tool was developed to provide a cost effective way to run pulsed neutron logs and combines conventional pulsed neutron technology with dual He³ detectors. Data from the detectors is recorded to the downhole memory module, uploaded at the surface and used to calculate the borehole and formation components of the decay curve. In addition, the near and far total counts are overlaid on the log to provide gas or low porosity zone indicators.

The MPNN tool is available in 1.625″ and 1.69″ diameter sizes, with a measurement point 5’ from tool bottom.
