James D. Patterson, L.G.

President and Principal Geologist

James Patterson leads technical projects, field operations, and systems engineering at Cenozoic Resources, and serves as Corporate Radiation Safety Officer. He has a decade of experience in borehole geophysics and vadose zone characterization at DOE sites, within a 20-year career in geology, hydrogeology, and geotechnical and analytical laboratory management.

Directed a research and development team building nuclear geophysical logging equipment, and reviewed logging systems, calibration certificates, and log data reports for QA/QC
Prepared neutron moisture and drywell monitoring log data reports for DOE tank farm characterization; logging methods include spectral and gross gamma, neutron moisture, gyroscopic deviation, acoustic, resistivity, caliper, and optical televiewer
Managed a geotechnical laboratory running more than 20 accredited test methods with up to 35 staff, and served as RSO under a Washington State radioactive materials license
As a U.S. Geological Survey hydrologist, developed the geologic framework for a regional groundwater model of the East Pasco Basin

Education and licenses: M.S. and B.S., Geology, Central Washington University; Washington Licensed Geologist No. 3274; RSO training, Radiological Worker II, 40-hour HAZWOPER. Author of 12 publications and presentations, including USGS Scientific Investigations Report 2016-5026 and a 2008 article in Nature Geoscience.

Dr. Russel R. Randall

Chief Scientist

Russel Randall is a nuclear logging physicist with five decades in borehole geophysics, including 30 years of vadose zone characterization at DOE sites. He has designed, calibrated, and characterized logging instruments for the petroleum industry and for DOE vadose zone monitoring. He founded Three Rivers Scientific in 1995 and developed the slim-hole spectral gamma, neutron moisture, and temperature tools that Cenozoic Resources acquired in 2025 and now operates at DOE sites. Three Rivers Scientific continues as an independent firm.

Led development of a pulsed neutron logging tool from concept to commercial use in 18 months, and directed a neutron generator manufacturing and research facility
Directed a theoretical research department characterizing nuclear, resistivity, sonic, and production logging instruments, and led development of a gamma-gamma density measurement-while-drilling tool
Developed and calibrated neutron moisture logging instrumentation for DOE vadose zone monitoring, co-developed the MCNP models used to calibrate the logs, and co-authored the 1996 calibration in the Hanford moisture models
13 patents in logging instrumentation; 20 technical documents for DOE site contractors; 28 industry and university papers
