It measures the volumetric hydrogen content (neutron porosity) of rocks. It includes a compensated neutron-neutron probe and a neutron gamma probe (2 thermal NNL + NGL).
The tool comprises the IBN-8-5 source.
Our Company holds licenses for designing, manufacturing and operation of devices that contain radioactive sources.
25 wells were drilled using the neutron-neutron logging module as of May 25, 2019.
