Full text
Abstract:
The concept of petroleum reservoir geophysics is relatively new. In the past, the role of geophysics was largely confined to exploration and, to a lesser degree, the development of discoveries. As cost‐efficiency has taken over as a driving force in the economics of the oil and gas industry and as major assets near abandonment, geophysics has increasingly been recognized as a tool for improving the bottom line closer to the wellhead. The reliability of geophysical surveys, particularly seismic, has greatly reduced the risk associated with drilling wells in existing fields, and the ability to add geophysical constraints to statistical models has provided a mechanism for directly delivering geophysical results to the reservoir engineer.

Abstract:
This review assesses the contributions and impact that GEOPHYSICS journal has made to both the theory and the applications of exploration geophysics during its publication life span. The contributions are evaluated first on the basis of Journal Citation Reports data, which summarize information available since 1975 about the impact factor of our journal. The impact factor for GEOPHYSICS in 1975–2002 has ranged between 1.461 and 0.591, with an average of 0.924 and with a relative ranking between 16 and 45 for all journals in its category. The journal receiving the highest impact factor for the period 2000–2003 in the “Geochemistry and Geophysics” category is Reviews of Geophysics, with an average impact factor of 7.787 and which ranged between 9.226 and 6.083. A second and important criterion is the frequency with which individual papers published in GEOPHYSICS have been cited elsewhere. This information is available for the entire publication history of GEOPHYSICS and supports the choices made for the early classic papers. These were listed in both the Silver and the Golden Anniversary issues of GEOPHYSICS. In August 2004, the five most-cited papers in GEOPHYSICS published in the time period 1936 to February 2003 are Thomsen (1986) with 423 citations, Constable et al. (1987) with 380 citations, Cagniard (1953) with 354 citations, Sen et al. (1981) with 313 citations, and Stolt (1978) with 307 citations. Fifteen more papers exceed a threshold value of 200 citations. During 2000–2002, GEOPHYSICS, Geophysical Prospecting, Geophysical Journal International, and Journal of Applied Geophysics were the four journals with the highest number of citations of papers published in GEOPHYSICS. In the same 2000–2002 period, those journals in which papers published in GEOPHYSICS are cited most are GEOPHYSICS, Geophysical Prospecting, Geophysical Journal International, and Journal of Geophysical Research. During 1985, the total number of citations in all journals in the Science Citation Index database to papers published in GEOPHYSICS was 2657. By 2002, this same citation count for GEOPHYSICS had increased to 4784.

Abstract:
Geophysical observations began in Australia with the arrival of the first European explorers in the late 18th Century and there have been strong connections with European and North American geophysics ever since, both in academic and exploration geophysics. Government institutions, particularly the Bureau of Mineral Resources, have played a large part in the development of the subject in Australia, certainly more so than in North America. Academic research in geophysics has been dominated by that at the Australian National University. Palaeomagnetic research at the Australian National University has been particularly valuable, showing the large northerly drift of the continent in Cainozoic times as part of the Australia-India plate. Heat flow, electrical conductivity and upper mantle seismic velocities have been shown to be significantly different between Phanerozoic eastern Australia and the Western Shield. Geophysical exploration for metals and hydrocarbons began in the 1920s but did not develop strongly until the 1950s and 1960s. There are relatively few Australian geophysical companies and contracting companies, and instrumentation from North America and Europe have played an important role in exploration. Exploration for metals has been hampered by the deep weathered mantle over much of the continent, but the development of pulsed (transient) electromagnetic methods, including an Australian instrument (SIROTEM), has improved the situation. Geophysics has been important in several discoveries of ore-bodies. In hydrocarbon exploration the introduction of common depth point stacking and digital recording and processing in reflection surveys have played an important part in the discovery of offshore and onshore fields, as in other countries.

Abstract:
A detailed citation analysis was conducted for fourteen major journals dealing with exploration geophysics, to judge their cost‐effectiveness and impact. The analysis was for papers published in 1984, so that papers had approximately five years of visibility at the time the citation analysis was conducted. In addition, a study was performed for Geophysics for the years 1980 to 1988, to assess the influence of the length of time a paper was in the literature. The leading journal, in terms of number of citations, was the Journal of Geophysical Research, which received an average of 17.4 citations per paper, followed by the Geophysical Journal of the Royal Astronomical Society (8.6) and Geophysics (5.4). Several journals average less than 1 citation per paper. For Geophysics, the average paper receives an extra 1.2 citations per year over the nine years studied. The percentage of nil citations decreases from 35 percent after one year, to 8 percent after 9 years. Four percent of papers receive 20 percent of all citations; these are the classic papers of exploration geophysics. Short notes, on average, receive half the number of citations as full papers. Self‐citations, which account for approximately one in five citations, do not appear to significantly affect the importance or relevance of a paper. When examined in terms of cost‐effectiveness, SEG publications rate very well. Geophysics and SEG Expanded Abstracts have the lowest cost per 1000 characters of all the journals studied. In terms of the number of citations per unit cost, Geophysics is more than twice as cost‐effective than its nearest neighbor, the Journal of Geophysical Research. The results also confirm those of earlier studies, that commercial journals are not as cost‐effective as those published by not‐for‐profit professional societies.

Most authors of GEOPHYSICS papers are from universities or government research institutions. That does not mean no interesting research is being done by the oil or geophysical industry. In the current competitive age, it is apparently difficult for geophysicists from the industry to find time to write elaborate papers for GEOPHYSICS. Therefore, the GEOPHYSICS editors have decided to encourage authors from the oil and geophysical industry to submit high-quality papers. SEG Editor Gerard T. Schuster asked me to develop a shorter route for such papers that have at least one author from the industry.

Abstract:
The origin and usage through time of geologia, geognosy, geogony, oryctognosy, geology and geophysics, as characterised by their frequency of occurrence in the Google Books Ngram Corpus, is discussed. The English, French, German, Italian and Spanish corpuses used in this study have been normalised over the same timespan using the average frequencies of occurrence of the same set of ‘neutral’ words in each language (as advocated by Younes and Reips 2019). Use of the term geology is found to predate publication of James Hutton's Theory of the Earth in 1795 by about 100 years; geognosy, oryctognosy and geogony, much less commonly used, became established in the 1780s and began to fall out of use around 1820. The terms geologist, and geognost follow a similar pattern. The emergence of geophysics is a less familiar field: While the phrases physics of the Earth and physical geography can both be traced back to the early 1700s, geophysics only began to be used in the early 1800s and did not really become common until about 1860; geophysicist becomes common in German after 1860, but more generally after 1880. The first geophysics-related publications were bulletins from magnetic and seismic observatories and its first dedicated journal, Beiträge zur Geophysik, began publication in 1887, eighty years after the formation of The Geological Society of London. The tems earth science and geoscience, popular today, have steadily increased in their usage since being introduced in the 1880s and 1930s respectively.

Abstract:
Geophysics is enhanced if the value it adds to society, economic systems, and the environment is assessed, understood, and communicated. A clear value proposition can inspire new generations of scientists to pursue careers in geophysics and motivate current geophysicists to expand their activities and utilize their skills in ways that could enable their long-term employability or entrepreneurship. One way to position geophysics and geophysicists as value creators is to map geophysical applications and practices to the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015. A Geophysical Sustainability Atlas was developed to illustrate how geophysics contributes to each of the SDGs and to provide examples of specific applications and collaboration strategies. The atlas aims to facilitate an understanding of the value geophysics brings toward achieving each SDG, providing geophysicists and stakeholders with a sense of being frontline contributors in the pursuit of these objectives and, at the same time, providing a visualization of current and future opportunities related to the sustainability of our world and our profession.

Abstract. In Anatolia, the history of geophysical sciences may go back to antiquity (600 BC), namely the period when Thales lived in Magnesia (Asia Minor). In the modern sense, geophysics started with geomagnetic works in the 1600s. The period between 1600 and 1800 includes the measurement of magnetic declination, inclination and magnetic field strength. Before these years, there is a little information, such as how to use a compass, in the Kitab-i Bahriye (the Book of Navigation) of Piri Reis, who is one of the most important mariners of the Ottoman Empire. However, this may not mean that magnetic declination was generally understood. The first scientific book relating to geophysics is the book Fuyuzat-i Miknatissiye that was translated by Ibrahim Müteferrika and printed in 1731. The subject of this book is earth's magnetism. There is also information concerning geophysics in the book Cihannuma (Universal Geography) that was written by Katip Celebi and in the book Marifetname written by Ibrahim Hakki Erzurumlu, but these books are only partly geophysical books. In Istanbul the year 1868 is one of the most important for geophysical sciences because an observatory called Rasathane-i Amire was installed in the Pera region of this city. At this observatory the first systematic geophysical observations such as meteorological, seismological and even gravimetrical were made. There have been meteorological records in Anatolia since 1839. These are records of atmospheric temperature, pressure and humidity. In the Ottoman Empire, the science of geophysics is considered as one of the natural sciences along with astronomy, mineralogy, geology, etc., and these sciences are included as a part of physics and chemistry.

SEG has propelled geophysics as a pure and applied science through decades of efforts to facilitate successful networking and collaboration among professionals in all segments of geophysics, but particularly in oil and gas. Through best-in-class programs, committees, technical events focused on specific topics, an array of publications that include The Leading Edge and Geophysics, online-learning resources, and activities for students, our Society has pioneered the positioning of geophysics as a primordial pillar in the exploration for energy resources. SEG has also been fundamental in envisioning integration strategies grounded on geophysical methods for the optimization of exploitation schemes and pivotal in highlighting new developments and technologies in applied geophysics. The progress of geophysics owes much to the collaborative efforts and networks created by SEG connecting the top geophysicists in the energy sector.

Upon entering the twenty‐first century, we see wide‐ranging changes in geophysics. As of this writing, quality and utility of geophysical data continues a trend of inexorable improvement punctuated by individual quantum steps (such as the 3-D seismic revolution). To a large extent, this improvement has been accomplished on the coattails of advances in computing and related disciplines. These advances have allowed cost‐effective implementation of methods that exploit our steadily increasing understanding of geophysical theory in ever increasingly realistic earth models. As a result, geophysical methods can now provide clearer images at greater distances with bette resolution and signal‐to‐noise ratio than ever before.

Abstract:
In the oil and gas industry, the geophysics bears the most knowledge-intensive and high-tech activity. The results of geophysical studies underlie the search, exploration and development of oil and gas fields. It is impossible to effectively drill, operate and repair wells without it. Success in the development of technology and technology in geophysics depends on the level of academic and industrial science, the effectiveness of the education system, and the intellectual training of personnel. The paper provides a historical insight into the era of geophysical research from the beginning of the last century to the present day. The current state and prospects of further development of the geophysical industry as the basis of Ukraine’s energy independence are analyzed. The main reasons for the negative state of affairs in Ukrainian geophysics are as follows: loss of professionalism, lack of high-quality basic education, lack of funding and short-sighted decision-making.

Abstract:
Geophysics has emerged as a significant and primary tool of archaeological research in Greece. It is no longer marginalized to a supporting role for excavations and pedestrian surveying, but has developed into a fundamental method of investigating layers of cultural heritage in its own right. This can be explained varyingly, from the increasingly holistic nature of archaeological fieldwork, to a broader appreciation of the diverse applications of geophysics to characterize historical contexts, the unique range of site assessment offered by geophysics and the capacity of geophysics to explore the subsurface in challenging conditions. Technology too plays a vital role. New generations of equipment have the ability to map archaeological features in high resolution, in rapid sequence and oftentimes in 3D. Geophysics along with other non-invasive methods, like satellite and airborne remote sensing, has also gained wider traction because of concerns about the costs, impacts and time horizons of traditional fieldwork practices. This brief report highlights some of the recent developments and applications of geophysical survey in Greece. It is not meant to be an inclusive account or an evaluation of each geophysical technique; instead, it emphasizes current trends in this important and expanding field of research and touches upon its future prospects in the country.

Abstract:
During the period 1990 to 1995, experimental programs using high‐resolution geophysics at several Australian operating mines and advanced evaluation projects were undertaken. The primary aim of those programs was to investigate the application of geophysical technology to improving the precision and economics of the ore evaluation and extraction processes. Geophysical methods used for this purpose include: 1) borehole geophysical logging to characterize ore and rock properties more accurately for improved correlations between drill holes, quantification of resource quality, and geotechnical information. 2) imaging techniques between drill holes to map structure directly or to locate geotechnical problems ahead of mining. 3) high‐resolution surface methods to map ore contacts and variations in ore quality, or for geotechnical requirements. In particular, the use of geophysics during evaluation of the Century zinc deposit in northern Australia demonstrated the potential value of these methods to the problems of defining the lateral and vertical extent of ore, quantitative density determination, prediction of structure between drill holes, and geotechnical characterization of the deposit. An analysis of the potential benefit of using a combination of borehole geophysical logging and imaging suggested that a more precise structural evaluation of the deposit could be achieved at a cost of several million dollars less than the conventional evaluation approach based on analysis from diamond drill‐hole logging and interpolation alone. The use of geophysics for the Century evaluation also provided substance to the possibility of using systematic geophysical logging of blast holes as an integral part of the ore extraction process. Preliminary tests indicate that ore boundaries can be determined to a resolution of several centimeters, and ore grade can be estimated directly to a usable accuracy. Applying this approach routinely to production blast holes would yield potential benefits of millions of dollars annually through improved timeliness and accuracy of ore boundary and quality data, decreased dilution, and improved mill performance. Although the indications of substantial benefits resulting from the appropriate and timely use of geophysics at Rio Tinto’s mining operations are positive, some challenges remain. These relate largely to the appropriate integration of the technology with the mining process, and acceptance by the mine operators of the economic value of such work. Until the benefits are demonstrated clearly over time, the use of geophysics as a routine component of evaluation and mining is likely to remain at a low level.

Abstract:
AbstractOver the past decades, the development of fibre optic cables, which pass light waves carrying data guided by total internal reflection, has led to advances in high-speed and long-distance communication, large data transmission, optical imaging, and sensing applications. Thus far, fibre optic sensors (FOSs) have primarily been employed in engineering, biomedicine, and basic sciences, with few reports of their usage in geophysics as point and distributed sensors. This work aimed at reviewing the studies on the use of FOSs in geophysical applications with their fundamental principles and technological improvements. FOSs based on Rayleigh, Brillouin, and Raman scatterings and fibre Bragg grating sensors are reviewed based on their sensing performance comprising sensing range, spatial resolution, and measurement parameters. The recent progress in applying distributed FOSs to detect acoustic, temperature, pressure, and strain changes, as either single or multiple parameters simultaneously on surface and borehole survey environments with their cable deployment techniques, has been systematically reviewed. Despite the development of fibre optic sensor technology and corresponding experimental reports of applications in geophysics, there have not been attempts to summarise and synthesise fibre optic methods for prospecting as a comprehensive and modern branch of geophysics. Therefore, this paper outlines the fibre optic prospecting methods, with an emphasis on their advantages, as a guide for the geophysical community. The potential of the new outlined fibre optic prospecting methods to revolutionise conventional geophysical approaches is discussed. Finally, the future challenges and limitations of the new prospecting methods for geophysical applications are elucidated.

Donald Macpherson was born in Edmonton, Alberta, Canada, on 6 October 1941. He passed on 20 August 2020. Though he was a proud Canadian till the end, he clung to his Scottish culture and became a fixture with his bagpipes at many events throughout the Dallas–Fort Worth area. He attended the University of Alberta, initially studying music and fine arts and earning a bachelor's degree in 1964 with a minor in math and chemistry. He graduated with a master's degree in isotope geochemistry and geophysics from the University of Alberta in 1965. Don walked into the “best job in the world” as a geophysicist at Mobil Oil Canada in 1965. There, he was responsible for seismic acquisition crews, processing, and interpretation of geophysical data.

Abstract:
Almost exactly 20 years ago, in July 2001, I organized and chaired the first SEG Summer Research Workshop on the topic of “Synergies in Geophysical, Medical and Space Imaging” (see The Leading Edge [TLE], 21, no. 6, 599-606). At the virtual SEG Annual Meeting in October 2020, special sessions were held on “Planetary Geophysics” and “Geophysics in Medicine.” Recently, I have been asked by SEG President Maurice Nessim to help lead two task forces to advance the use of applied geophysics in both the medical and space sciences. It is therefore an excellent time to share some thoughts on the next 20 years of collaboration possibilities in these areas.

Abstract:
As unconventional resources continue to be the focus of many operating companies, applications of cost-efficient practices along with technological advancements in drilling and completion will continue to be key enablers for efficiency and obtaining economies of scale. However, this pursuit of efficiency has led to a perception that developing these resources is strictly an engineering-optimization endeavor. This perception suppresses the value of geophysics in addressing uncertainties related to reservoir quality and completion effectiveness. Eventually, it may hinder unlocking the full potential of these resources. Despite this narrative about efficiency versus effectiveness, geophysics is challenged by inherent constraints such as noise, resolution of data, and the ability to identify economic sweet-spot fairways. Therefore, geophysicists encounter difficulties quantifying the value of geophysics in unconventional resource plays and struggle expressing it in economic terms. This paper sheds light on an SEG workshop, “Maximizing the value of geophysics in unconventional resource plays,” that was conducted in Dubai in October 2018. A total of 52 attendees from 17 companies and nine countries took home one common message: “How can my geophysical work positively impact the bottom line, i.e., $/BOE.” The workshop addressed questions related to how the value of geophysics can be realized and measured throughout the unconventional asset life cycle and how this value can be maximized and expressed in economic terms.

Abstract:
We present an approach to the use of electomagnetic geophysical methods for delineating groundwater contamination, and test the concepts at three waste disposal sites. The approach includes a technique for modelling a site's response to a variety of instruments, and a device-independent method of contouring the data. The modelling attempts to account for the noise inherent in the measurement process, particularly the effects of lateral variations in stratigraphy. These concepts are evaluated by comparing the geophysical response to groundwater conductivities measured in sampling wells. We conclude that geophysics offers a cost-effective supplement to drilling, and that it is best used in a reconnaissance mode to map the general distribution of contamination prior to a detailed sampling program. The correlation between the observed and predicted geophysical response as a function of groundwater conductivity is as good as can be expected given the uncertainties in the process. The methodology proposed is simple to use and practical. Key words: groundwater, contamination, geophysics, electromagnetic, mapping, modelling.
