Alexander Arkadyevich Kaufman (1 August 1931 – 7 June 2023)[5][6] was a geophysicist and professor. He directed the Laboratory of Electromagnetic Fields at the Trofimuk Institute of Petroleum-Gas Geology and Geophysics (IGG) and also served as head of the Department of Geophysics at Novosibirsk State University (NSU). Kaufman later taught as Professor in the Department of Geophysics at the Colorado School of Mines (CSM)[1]. His research focused on surface, borehole, and deep electromagnetic sounding. He authored and co-authored 18 monographs in English[7] and several in Russian, as well as numerous papers. He held a United States patent.[8]
Biography
[edit]Kaufman graduated from the Geophysical Faculty of the Russian State Geological Prospecting University (MGRI) in 1954 and began working in the research division of MGRI.[6]
He earned his Candidate of Sciences degree in 1959 and his Doctor of Technical Sciences degree in 1965.[5] He was awarded the title of professor in 1969.[9]
In 1975 Kaufman left the USSR and later worked in Toronto, Canada, at Scintrex Ltd. and as a consultant for Geonics Ltd. [10]
In 1977 he moved to the United States, continuing his academic career at the Colorado School of Mines in Golden, Colorado.[11], where he taught geophysics.
Kaufman initiated the GEOFIZIK Charity Fund to support Russian scientists who needed medical assistance.[1]
Family
[edit]Kaufman was married to his first wife, Irina, for 56 years until her death. After his death, he was survived by his second wife, Natalie, and his son from his first marriage, Dmitry.[5]
Research
[edit]Kaufman worked on the theoretical foundations of electrical prospecting and well logging. He worked on solving direct problems of electromagnetic (EM) fields in complex media.[12], compared amplitude–phase and transient process methods, and created or improved several practical EM techniques.[13]
Exploration geophysics
Kaufman developed the near-field transient electromagnetic sounding method (ZSBZ), also known as TDEM (Time-Domain Electromagnetics).[14] The method enabled deep geoelectrical surveys using compact equipment and close transmitter-receiver spacing.[5] The method was used in oil exploration on the Siberian Platform[15] and in searches for deep ore deposit in Krasnoyarsk Krai, Yakutia, and the Altai region.[16]
Well logging
Kaufman extended L. M. Alpin’s concept of using the second derivative of the electric field potential to determine formation conductivity through casing.[17] He added a calibration method to account for variations in casing conductivity. The patented solution[8] has been used for fluid tracking[5] and reservoir management.[18]
He also contributed to the development of transient and induction logging.[1] In the book Theory of Inductive Prospecting, he described the dual-frequency modification method (FDEM), which combined features of both frequency and time-domain approaches.[13][5] The FDEM was later developed by his former students into a logging technique capable of measuring formation conductivity and electrical anisotropy.[19][1]
In the monograph Principles of Dielectric Logging Theory (2021),[20] Kaufman presented a theoretical foundation for dielectric logging from first principles to instrument design.
Scientific school and teaching
[edit]Between 1965 and 1974, Kaufman led the Laboratory of Electromagnetic Fields at the Institute of Petroleum-Gas Geology and Geophysics (IGG) and headed the Department of Geophysics at Novosibirsk State University.[6] According to an obituary in SPWLA Today, the laboratory was associated with several generations of researchers in electromagnetic well logging and geophysics.[5]
He supervised a number of PhD students, including L. A. Tabarovsky[3], Yu. N. Antonov and M. I. Epov who later earned doctoral degrees.
Kaufman was a faculty member at Novosibirsk State University from 1963 to 1974[9] and at the Colorado School of Mines from 1977 to 2004.[9][11] His courses covered electromagnetism, geophysical exploration methods, and electrical prospecting.[11]
A 21-part lecture series titled “Electromagnetic Phenomena and Their Application in Mining and Exploration” is available on YouTube.[21]
