revolution
We are on the verge of a second quantum revolution, building on the one that occurred in the last century. The first revolution involved manipulating groups of quantum particles like electrons and photons, which led to the development of technologies such as transistors and lasers that completely transformed the world. The second revolution, which began in the 1980s and has gained momentum in recent years, is expected to be even more transformative. It involves manipulating individual quantum particles and utilizing the quantum phenomena of superposition, entanglement, and interference. This leads to the development of three new technologies: quantum computing, quantum communications, and quantum sensing.
Milo Backus was an American geophysicist, pioneer in 3D seismic imaging, and the 1979-1980 SEG President. Milo Backus has won the highest honor given by SEG (the Maurice Ewing Medal in 1990) and by EAGE (the Conrad Schlumberger Award in 1975); he was made an Honorary Member of SEG in 1988; he has been elected to the SEG Executive Committee on two occasions; and he was a major factor in the Distinguished Achievement Awards that SEG bestowed on GSI in 1986 and 1989. This abbreviated list of honors endorses the point made in his citation (see TLE, February 1991) for the Ewing Medal that here is an individual of great vision, possibly one of the greatest in the history of our profession. Milo was one of that fabulous group of MIT graduates who entered the field of applied geophysics in the 1950s and played such a huge role in the digital revolution in our field.

Ludger Mintrop (July 18,1880 - January 1, 1956) was a German mine surveyor and geophysicist. Mintrop is considered the inventor of the seismic method for exploration of hydrocarbons and minerals (Patent 1916), through the seismic refraction method. Among the many accolades and awards in recognition of his seminal work in seismic prospecting, Mintrop was awarded SEG Honorary Membership. Ludger Mintrop was born the fifth son of 15 children on July 18, 1880 at his parents' Barkhoven estate near Essen-Werden. He passed his matriculation examination at Aachen Grammar School. Subsequent to a thorough practical training in the Ruhr mining industry, he studied at the Mining Academy in Berlin and at the Technical University in Aachen under Professor Karl Haussmann. In 1905, after passing the civil service examination, he obtained his papers to become a mining surveyor and then returned first of aIl as an assistant to Haussmann, where he experienced the decisive contact with geophysics. After setting up a seismic station in Aachen based on the Goettingen prototype, he moved in 1907 to study with Wiechert in Goettingen and was encouraged to undertake thorough tests with artificially produced earthquakes and to construct more easily transportable seismographs. Upon his appointment as a lecturer in mining surveying at the School of Mines in Bochum, he set up here too a seismic station, but at the same time pursued his ideas of applying seismics to practical purposes.

The seismic industry has been impressively dynamic and creative during its 60-year history. Although it is relatively a small sector within the oil and gas industry at large, it has made the most significant impact on increasing proven reserves and reserve-production ratios worldwide. We shall now sketch a brief historiography of the seismic industry before we look ahead. The evolution of the seismic industry can be described briefly in decades of development and forward leaps from one theme to another as outlined in Table I-1. In the 1960s, the digital revolution profoundly changed seismic acquisition.

Enders A. Robinson (1930–2022) was an American Geophysicist and one of the scientists responsible for the transition from analog to digital data processing in geophysics. Enders was the Maurice Ewing and J. L. Worzel Professor of Geophysics at Columbia University in New York City. Robinson gained international prominence in the early 1950's when he was the founder of the Geophysical Analysis Group (GAG) at MIT. GAG research lead to the digital revolution in geophysics a decade later. Robinson published more than 25 books on digital signal analysis, seismic data processing, and wavelet estimation. Robinson helped found Digicon in 1965; there he developed the first commercial programs for academic positions, including the McMan Distinguished Professor of Geophysics at the University of Tulsa. Robinson was the highest honored scientist in the field of geophysics, SEG's Reginald Fessenden award 1969, the EAEG's CSch award 1969, and the IEEE's DGFP award 1984.

Steve lays out the case for why the seismic you have is better than you think. He argues that the industry needs to undergo a complete change of mindset regarding visualization. Steve explains a natural seismic display, the third form of resolution that's often ignored, and the unsung technological hero of the 20th century. Steve hopes to convince you that there's a tremendous amount that you're not seeing. And that most of the information acquired in seismic has yet to be observed or interpreted.

Abstract The objective of bit selection is to drill a round, ledge free hole, without patterns, with minimum vibration, minimum dog leg severity, that reaches all directional and geologic targets. And to do this in one run per section where rate of penetration (ROP) is unconstrained by the bit, and it remains vibration free in control drilling situations. The objective of this paper is to share these guidelines, accumulated from forensics investigations and sometimes costly lessons learned over the past decade. Bit selection can be based on; offset runs, forensics analysis, and first principles. Offsets capture past learnings. Forensics analysis is applied to past and current wells, and it is the foundation for continuous improvement. First principles, based on independent thinking, are required to challenge the status quo. These guidelines are the distillation of forensics observations, offset analysis, and physics modeling. It is important to note that these are guidelines, not rigid standards. They are presented in their current state, to be challenged, tested, and revised as new ideas and technology are developed. They are not a substitute for thinking. The guidelines start with a description of the formation properties, drilling environment, and other requirements such as directional objectives, drill out considerations, and required life. They cover how to suppress bit whirl, stick slip, and borehole patterns; improve structural integrity, allow for predictable build rates, reduce gauge trimmer damage, and design for appropriate aggressiveness, ribbon flow, bit stability and life. These functions and dysfunctions are paired with design features such as depth of cut elements; gauge pad length and relief; cutter materials, size, and geometry; back rake; blade count and standoff; hydraulic design; and blade strength. The guidelines document specific and general lessons learned and why each rule was established. They help drilling engineers and service companies determine which design features are most important for a given application. Applying them across teams and applications highlights design elements that may be of concern and has helped avoid repeat failures. The first failure is for learning, the second failure is a failure to learn. Design features have been matched up with associated critical performance limiters. This transparency in thinking allows the assumptions to be questioned, provides knowledge of which rules apply in each application, and provides background to evaluate when new technology may help. Some of the hard problems that remain are; consistent forensics analysis, chip flow modeling, cutter stress verses rock strength and penetration per revolution, understanding and suppressing high frequency torsional oscillation, and improvement and expansion of in-bit instrumentation.

Abstract Industrial revolutions have been significant in shaping the modern world as we know it because it brings transformation across technology, economic and societal structures. Each revolution represents a shift in the way goods are produced, services required in production, labor and human capital dynamics and even daily life of society. The question of whether revolutions indeed occurred historically has been subject of the works of revisionists and historians and there have been debates over the establishment of a timeline during which these events happened. This may have been because of the localization of the early Industrial revolutions. For this reason, arguments about what exactly changed, when it started, when it ended, and where to place the emphasis keep raging. Another reason for this contemplation is the drawn-out periods attributed to these revolutions. The retrospective presentation of Industrial revolutions may not necessarily paint the same picture as with people who lived through them without the benefit of hindsight. Four different schools of thought were thus identified as concerning what mattered or what changed during the Industrial Revolutions. The Social Change School, The Industrial Organization School, The Macroeconomic School and The Technological School. These schools have different areas of emphasis yet overlap to a point where clear line of distinction cannot be made.

Abstract This paper outlines the creation, implementation, execution, and assessment of the first 16" usage of a hybrid bit on a rotary steerable system for drilling lengthy interbedded formations with up to 50% of abrasive cherts in Unconventional Gas reservoirs. The main hurdle overcome by the solution was drilling through the tough layers of chert while steering clear of trips caused by damage to the PDC bit or time constraints of Tricone Bit Inserts. Furthermore, it improved the overall drilling speed (ROP) and met the necessary directionality. This solution proved superior in ROP compared to rollercone bits, in addition to enhancing PDC cutter durability and decreasing reactive torque, leading to improved steering and stability, which will be further explored in this paper. A key element to the success was the use of a new hybrid bit technology that combines the cutting methods of both Polycrystalline Diamond Compact (PDC) and rollercone bits. This allowed for more efficient drilling by employing the robust crushing action of rollercone to penetrate tough interbedded rock layers and the effective shearing action of PDC cutters to boost ROP without compromising the toughness of the cutting structure's edge. Combined with the continuous proportional rotary steering system, the proposed solution successfully drilled a footage of 7,018 ft through a mixed formation with chert nodules, achieving an average ROP of 47 ft/hr. It reached the casing point in a single run, eliminating the need for additional trips using rollercone bits to drill through the sizable cherts and preventing damage to the PDC bit. This resulted in a 30% cost reduction per foot. Furthermore, the hybrid bit outperformed expectations, accomplishing 1.49 million revolutions, with an efficient bearing and well-preserved drilling cutting structure. The directional goals were also achieved with high-quality directional drilling that avoided colliding with neighboring wells. This success was made possible through careful analysis, creating drilling plans for specific formations, and optimizing drilling parameters for improved overall efficiency. The incorporation of rollercone and PDC components in a hybrid bit, specifically designed for better efficiency and torque stability, greatly improved drilling performance by completing the section in one single run. This confirms that varied rock formations can be drilled end to end.
