Serge Alexander Scherbatskoy (1908-2002), a petroleum geophysical
engineer, held more than 200 patents worldwide in petroleum exploration.
Scherbatskoy was born July 18, 1908, in Buyuk Dere, Turkey, a
suburb of Constantinople where his father, Alexander Ippolitovich
Scherbatskoy, was Third Secretary to the Russian Embassy. After
the Russian Revolution of 1917, Alexander Ippolitovich planned
to accept a post in the Kerensky government. When that fell, he
joined the League of Nations offices in Berlin. Later, he moved
the family to Paris where he was employed by Yokohama Specie Bank.
Young Serge completed his education at the Sorbonne, earning a
degree in physics in 1926.
In 1929, only months before the stock market crash, Scherbatskoy
immigrated to the United States. He worked for Bell Labs in New
York City from 1929 to 1932. While there, Scherbatskoy worked
on the Type C Carrier telephone system, assisted in the Reproduction
of Music in Auditory Perspective (the first Hi Fi) and invented
an automatic volume control using copper oxide semiconductors,
for which the patent was denied. About this time, he met Mary
Ellen Dunham; they married in 1938 and had four children: Mary,
Serge, Timothy, and Jonathan.
After being laid off from Bell Labs in 1932, Scherbatskoy held
a number of odd jobs. He organized the “Bureau of Radio
Engineering” to repair radios house-to-house. In 1933, he
went to the University of Pennsylvania under a grant from the
Works Progress Administration (later Work Projects Administration;
WPA) and assisted with developing a “sound prism”
(i.e., spectrometer). He worked for PHILCO Radio and Television
Corporation from 1933 to 1934 where he developed a “sweeping
frequency” oscillator for testing radios. About 1936, Scherbatskoy
headed west to Tulsa, Oklahoma, and joined Seismograph Services
Corporation. While at Seismograph, he developed the “Expander”
and the “Automatic Signal Control” for use in seismographic
exploration.
Scherbatskoy left Seismograph Corp. and, with Bill Green and
Jerry Westby, started Well Surveys Incorporated in 1937 to develop
his idea of nuclear logging of cased wells. In nuclear logging,
logs are obtained by using radiation sources in the logging tool.
Well Surveys was one of the first American companies that applied
nuclear physics to oil prospecting. Standard Oil of New York financed
the project, but various parties could not agree and they dissolved
the Well Surveys Incorporated.
According to an audiotaped interview conducted by Scherbatskoy’s
daughter Mary, during World War II Serge Scherbatskoy worked for
the U.S. Navy as an independent prime contractor to develop the
lethal probability integrator (aircraft gunner training simulator)
and other projects. Scherbatskoy also was involved tangentially
with the Manhattan Project. As part of the Project, Scherbatskoy
was recruited by Gilbert LaBine (1890-1977), a Canadian prospector
who discovered radium and uranium deposits at Port Radium, Northwest
Territories in 1930. Known as the father of Canada's uranium industry,
LaBine was president of Eldorado Mining and Refining Limited from
its start in the late 1920s to 1947. Scherbatskoy developed a
portable radiation detector and headed a team pioneering this
form of uranium exploration near Great Bear Lake, Canada, during
1944, locating deposits used in atomic weapons production.
In 1948, Scherbatskoy formed Geophysical Measurements Corporation
(GMC) in Tulsa, Oklahoma. During this time, Scherbatskoy worked
on the development of well logging technology. “Well logging
is the process of exploring systematically the entire length of
a drill hole by means of an instrument capable of measuring physical
factors associated with the rocks traversed and producing a graph.”1
In December 1960, Scherbatskoy, Jan J. Arps (physicist), and Jacob
Neufeld (physicist) joined together with Reinholdt & Gardner
(a brokerage firm) to form a limited partnership named Arps Corp.
to assign, sell and license patents. The purpose was to lease
to the oil industry, equipment utilizing the patented Arps process
for continuous telemetering to the earth’s surface of measurements
made at the bottom of a borehole while drilling.
In 1964, GMC conducted a stock swap with McCullough Tool which
then went bankrupt in 1968. During the 1970s, Scherbatskoy’s
activities included consulting with Jacob Neufeld of Oak Ridge
National Laboratories. In 1973 he began a relationship with Marvin
Gearhart of Gearhart-Owen Industries of Dallas, Texas. Gearhart-Owen
was an instrument and oil services firm originally founded by
Marvin Gearhart and Harold Owen in 1955. In 1980, Marvin Gearhart
changed the name from Gearhart -Owen to Gearhart Industries, Inc.,
“The GO Company.” Scherbatskoy was named Director
of Special Projects and continued his own patent program which
developed “Measurement While Drilling” and directional
drilling patents.
"Measurement While Drilling" (MWD) refers to measurements
acquired down hole while drilling that specifically describe directional
surveying and drilling-related measurements. “Logging While
Drilling” (LWD) refers to petrophysical measurements, similar
to open hole wireline logs, acquired while drilling. Wireline
logs are a cabling technology used by operators of oil and gas
wells to lower equipment into the well. Directional drilling is
the science of drilling non-vertical wells. These systems—MWD
and LWD—are based on mud telemetry which is the transmission
of encoded data through a drilling rig's drilling mud system using
rapid fluctuations in the pressure of a closed loop circulating
system.
When Gearhart-Owen went bankrupt in 1986, it was acquired by
Halliburton. Scherbatskoy worked at Gearhart-Owen until 1988,
when he opened his own office in Fort Worth developing Measurement
While Drilling patents. Scherbatskoy died on November 25, 2002
in Fort Worth, Texas.
1 Oil and Gas Journal,
February 22, 1940, p. 62.
The Scherbatskoy papers provide insight into the relationship
between inventors and the United States oil industry between the
1930s and 1990s, the evolution of the history of applied geophysics,
and the development of technological innovation in oil prospecting,
specifically applied and geophysics. One of the strengths of the
collection is the patents Scherbatskoy pursued, renewed, or impeded.
As sole proprietor of his own company, Geophysical Measurements
Corp., Scherbatskoy meticulously constructed an international
patenting program which made him a successful player among the
giants of the oil industry. Another highlight of the collection
is Scherbatskoy’s fifteen laboratory notebooks that include
his well logging work notes and drawings. Legal files illustrating
litigation over the infringement of Scherbatskoy’s patents
are also found in the collection. The papers demonstrate how the
oil prospecting industry worked from scientific, commercial and
legal perspectives. The bulk of the papers are arranged chronologically
to reflect the timeline of Scherbatskoy’s career. Due to
the limited number of personal materials, Scherbatskoy’s
personal papers are placed at the end of the series list.
Series 1, World War II Work, 1935-2002, is
divided into three subseries and includes information on Scherbatskoy’s
relationship with physicists Bruno Pontecorvo (1913-1993) and
Jacob Neufeld (1906-2000). Neufeld and Scherbatskoy worked on
the application of nuclear physics to geophysical prospecting.
Neufeld would later join the staff of Oak Ridge National Laboratory.
Materials include a file about Pontecorvo, Neufeld’s laboratory
notebook, and some correspondence between Neufeld and Scherbatskoy.
This series also includes materials on Scherbatskoy’s well
logging projects during and after World War II.
Series 2, Invention Laboratory Journals and Drawings,
1958-1992, is further divided into two subseries and
includes fifteen laboratory journals and a folder of drawings
related to Scherbatskoy’s well logging work. The journals
are arranged numerically by journal number. In some instances,
journal numbers repeat. Journals are paginated and include drawings,
tipped-in graphs and charts, and notes relating to Scherbatskoy’s
well logging work. Some of the notebooks include pages signed
by a witness, which Scherbatskoy could use as evidence to prove
his ownership of a particular well logging invention idea.
Series 3, Radio Corporation of America (RCA), 1946,
1948, is comprised of one folder with a license agreement
between Scherbatskoy and Radio Corporation of America for magnetic
recording systems.
Series 4, Canadian Geophysical Measurements Corporation
(GMC), 1957-2002, is divided into three subseries and
provides information on Scherbatskoy’s company Canadian
Geophysical Measurements Corporation. Materials include license
agreements, correspondence, and Canadian Geophysical Measurements
vs. Computalog Gearhart, Ltd litigation files.
Series 5, ARPS Corporation (Jan J. Arps), 1960-1995,

Jacob Neufeld, and Jan J. Arps in Dallas, TX to develop and practice
measurement while drilling. The Arps Corporation materials are
comprised of administrative and financial records, business correspondence,
contracts of consultation, patents, license agreements, and Scherbatskoy’s
stock information.
Series 6, Gearhart-Owen Industries (GOI) (Gearhart Industries,
Inc., (GII)), 1961-1996, is divided into seven subseries
and consists of records generated during Scherbatskoy’s
measurement while drilling (MWD™) work with Gearhart-Owen
Industries, Inc. One of the largest series in the collection,
the Gearhart-Owen materials include license agreements, correspondence,
litigation files, measurement while drilling reports and blue
line prints of measurement while drilling equipment, signal extraction
measurement while drilling study reports, reference materials,
and United States, United Kingdom, and Canadian patent assignments
between Scherbatskoy, Gearhart-Owen, and the Scherbatskoy Family
Trust. Included in the litigation subseries is the Scherbatskoy
Family Trust vs. Gearhart Industries, Inc., case. The Scherbatskoy
Family Trust in 1975 sued for royalty payments due Scherbatskoy
under the Scherbatskoy Gearhart-Owen Agreement on nuclear well
logging technology and measurement while drilling. The case was
settled in the late 1980s, and Gearhart Industries, Inc., paid
royalties to the Scherbatskoy Family Trust. Gearhart materials
are also present in Series 7, 8 and 9.
Series 7, Halliburton Company, 1978-1999, is
divided into four subseries and includes license agreements, lawsuits
and patent infringements, patents, and company acquisitions. This
series documents Scherbatskoy’s relationship with the Halliburton
Company pre-and post-Halliburton’s acquisition of Gearhart
Industries in the 1980s. Halliburton materials are also in Series
8 and 10.
