Private Consultant (1996-1998) Senior Scientific Advisor (1998-1999)
Improved accuracy of hostile neutron and LWD neutron tools to increase competitive/commercial status as
premium logging tools. Developed new generation neutron porosity measurement systems for both open
and cased boreholes.
· Redesigned hostile neutron tool’s calibration, ratio-to-porosity transform, and environmental correction
algorithms and realtime software, resulting in significant improvement in porosity measurement
accuracy.
· Developed enhanced vertical resolution processing algorithms / software for this neutron tool and
integrated with gamma ray, density, and dual induction tool enhancements, thereby upgrading the
commercial position of the entire hostile tool string.
· Optimized designs for new generation neutron logging tools for open and cased boreholes. ISO 9000
certifications pending. Achieved higher logging speeds, better accuracy, and lower costs.
· Revised calibration procedures for 6 ¾” LWD neutron tool and its sandstone response, improving
measurement accuracy and satisfying clients’ concerns.

feasibility for automatic scanning of borehole acoustic images for fractures, cavities, and laminated
sections.
WRT ENERGY SERVICES – HARC - The Woodlands, Texas 1993 - 1996
Private Consultant
Provided scientific, hardware, and interpretative software for two novel gamma ray spectroscopy logging
tools, both for through-tubing wireline applications.
· Applied classical dual-water model for analyses of oil, water, sand and clay volume fractions from
capture gamma ray tool’s spectral data. Trained a neural net to provide the same analyses
automatically. This was an industry first for slim through-tubing logging tools and neural net
technology.
· Utilized both singular value decomposition and neural net methods for determining quantitative K, U
and Th concentrations from natural gamma ray tool’s spectra data that worked in casing or in casing
plus tubing. This was also an industry first.
· Demonstrated that BGO is superior to NaI(Tl) for carbon / oxygen inelastic gamma ray measurements
with pulsed neutron generators.
