The MPNN tool is cost-effective for running pulsed neutron logs on slickline or coiled tubing. This short, slim tool string can get in many wells where more extensive 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. For example, gas/oil/water contacts missed the analysis of hydrocarbon zones and time-lapse water saturation.

The tool’s physics maintains statistical accuracy in low-salinity formations and is less dependent on the fluid type. Further, in the borehole to deliver accurate results. The development of the MPNN tool provided a cost-effective way to run pulsed neutron logs. Therefore, the combined conventional pulsed neutron technology with dual He³ detectors. As a result, detectors recorded the data. For instance, in 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. In short, with a measurement point 5’ from tool bottom.
