Systems, methods, and devices for matching the lithology effect of a downhole tool having a lower-energy neutron source, such as AmBe, using a downhole tool having a higher-energy neutron source, such as an electronic neutron generator, are provided. One such downhole tool may include a neutron source, first and second neutron detectors, and data processing circuitry. The neutron source may emit neutrons into a subterranean formation, which may scatter off the formation. The first neutron detector may detect neutrons of a relatively lower spectrum of energies than the second neutron detector. From counts of these neutrons, the data processing circuitry may determine a property of the subterranean formation having a lithology effect that substantially matches another lithology effect associated with another downhole tool having a lower-energy neutron source. |
