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.

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

Geophysics aims to image subsurface geologic structure and identify different geologic units. While the former has dominated the interpretation of applied geophysical data, the latter has received much less attention. This appears to have persisted despite applications such as those in mineral exploration that inherently rely on the inference of geologic units from geophysical and geologic observations. In practice, such activities are routinely carried out in a qualitative manner. Thus, it is meaningful to examine this aspect and to develop a system of quantitative approaches to identify diff

An essential need for carbon sequestration is to have benchmarks that can be used to measure the geophysical responses to CO2 injections to evaluate different monitoring approaches. The primary purpose of the SEG Advanced Modeling Corporation (SEAM) CO2 project is to build realistic geologic models and to conduct simulations that provide data that can be used to test geophysical tools without field experimentation. A necessary requirement to meet our goals is to test the efficiency and accuracy of the various needed simulation and processing systems (geology, reservoir, geomechanics, geophysic

Void detection is a difficult task for geophysical methods. The main disadvantage is the uncertainty of the final interpretation and the need for verification of the results with direct methods of underground investigation. A good way to reduce this uncertainty, apart from drilling, is through the implementation of more than one geophysical method in the same area. An integrated approach of geophysical methods can be achieved by using multiparameter statistical techniques, such as cluster analysis. Firstly, the effectiveness of multiparameter analysis on synthetic data is studied and then on r

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 in

Neural networks are increasingly popular in geophysics. Because they are universal approximators, these tools can approximate any continuous function with an arbitrary precision. Hence, they may yield important contributions to finding solutions to a variety of geophysical applications. However, knowledge of many methods and techniques recently developed to increase the performance and to facilitate the use of neural networks does not seem to be widespread in the geophysical community. Therefore, the power of these tools has not yet been explored to their full extent. In this paper, techniques

Abstract. A brief summary will be given of the historical development of Geophysical Service of Austria, which comprises the national geomagnetic, gravimetric and seismological services as well as the “Applied Geophysics Section” located at the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Vienna in Austria. The paper presents the achievements, changes and challenges of the Department from its modest beginning in 1851 until 2020. Finally, a special emphasis is placed on the Conrad Observatory – one of the most comprehensive geophysical research observatories in the world.

The similarities and crossovers between geophysical and medical imaging are well known and documented (see President's Pages by D. Lumley and J. Zhang in the March 2021 and June 2022 issues, respectively, for two recent examples from this journal). Each of the two industries has introduced technology of tremendous value to the other, and one can only imagine what future advancements in medical imaging may bring to exploration geophysics — and vice versa. Welcome to the wonderland of the intersection of geophysical imaging and medical imaging.

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 201

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 citation

China is increasing its investment in the petroleum industry, with a goal of significantly expanding domestic oil and gas production.
