  • Issues with compensated neutron log response

    W. A. Gilchrist, Jr. and Noel Atzmiller, Baker Hughes Inc.

    Compensated Neutron (CN) logs have been around for many years and used successfully for many petrophysical applications. Although the basic design and general response characteristics of these instruments have remained relatively constant over the years, service companies have refined the response characterizations and have updated their hardware, providing evolutionary improvements. Unfortunately, the general understanding among earth scientists of how CN instruments work and how to make the best use of the log data appears to have lagged, or perhaps even worsened, in recent years.
