Nuclear Applications in the Oil Industry
Brad Roscoe Scientific Advisor and Nuclear Program Manager Schlumberger-Doll Research Oil-Field Service companies, like Schlumberger, provide services to oil companies to help them identify and efficiently produce oil from their wells. As a service company, we provide many things to our clients, the most important being information. A large part of our business is supplying petrophysical information for an oil-well including many parameters such as: porosity of the rock, type or rock, permeability of rock, type of fluids present, characteristic of fluids, etc… To accomplish this, we utilize any physical measurement that may give us information concerning these parameters of interest; for example, electromagnetic, sonic, ultrasonic, nuclear magnetic resonance, and nuclear measurements. This talk will give a background of the nuclear technology that has been developed for the oil industry and how is applied. There is quite an impressive list of nuclear technology that has been developed for the oil industry including neutron generators, linear accelerators, scintillators (LSO was invented by Schlumberger), and signal processing. The fact that these technologies need to operate at 150 to 175oC and at 20 to 30 kpsi while being no larger than 1-3 inches in diameter adds extra challenges to the technology. In addition, the borehole geometry in which the measurements must be performed complicates getting reliable information as does the fact that we have to provide useful information with only several seconds of data accumulation. Come hear about the nuclear measurement challenges in the oil-field service industry. Brad Roscoe is a Scientific Advisor and Nuclear Program Manager at Schlumberger-Doll Research in Cambridge, MA. Brad has been with Schlumberger for 26 years where he has developed pulsed-neutron tools and measurements for borehole applications. Currently, he is working in research on the development and application of nuclear technology to downhole applications. He has 32 outside publications and is a holder of 16 patents. Brad obtained a BS degree in Electrical Engineering (1975) and an MS degree in Nuclear Science and Engineering (1976), both from Virginia Polytechnic Institute and State University and a Ph.D. degree in Nuclear Engineering (1981) from University of Illinois.
