NUCLEAR INSTRUMENTATION; OIL EXPLORATION; PETROLEUM PRODUCTION. For about five years, Expert consulted with Teleco Oilfield Services on the design of nuclear Measurements While Drilling (MWD) tools. He offered expertise in nuclear physics experimental methods, nuclear instrumentation, radioactivity, vacuum technology, photomultipliers, and geophysics. He co-invented the Schlumberger SNP and CNL neutron porosity tools, which are widely used by the oil industry for use in petroleum exploration and production. He developed a borehole accelerator used to make thermal decay time measurements and to do capture gamma-ray spectroscopy. The borehole accelerator is a sealed tube about a foot long and one inch in diameter. It produced 14 MeV neutrons at an intensity of 10(8) neutrons/sec. In order to perfect this device, he used his knowledge of gas discharges, high voltage insulation, and nuclear reactions.

Expert designed and developed neutron tools that use chemical sources. These sources are small doubly encapsulated cylinders, typically 1-3 inches long and less than one inch in diameter. Contained in such capsules is a mixture of beryllium and some other element that happens to be an alpha-emitter (alpha is a helium nucleus).

NEUTRON MEASUREMENT. For the last 20 years Expert was with Schlumberger, he helped design and develop thermal and epithermal neutron measurement tools. These tools are currently the only two kinds of neutron measurements that can be made involving slowed down neutrons. One of the measurements he co-developed brought $200 million in annual revenues.

Expert is a member of the American Physical Society, Sigma Xi, Society of Professional Well Log Analysts and previously Sigma Pi Sigma. He also holds membership in the Connecticut Bar Association.

Expert has been admitted to practice law before the Federal District Court and all Connecticut courts.

"Depth of the Investigation of the CNL," one of the numerous technical articles Expert has authored, won an award for best presented paper at a meeting of SPWLA.
