Published: November 2024

Abstract
In recent years, pressure in the annulus of gas storage reservoir injection wells has become increasingly common. This presents a significant challenge to the safe and efficient operation of gas storage reservoirs and the integrity of injection wells. This paper presents a systematic introduction to the prevention and control measures of annular pressure. The introduction is based on research into the development status of prevention and control methods both domestically and internationally. The measures mainly include two aspects. Firstly, for the sealing failure of the tubular column, the differential pressure activated blocking agent is used for management. Secondly, for the sealing failure of the cement ring, the sealing agent is managed by extruding cement, resin, and other blocking agents. The text analyses the advantages and disadvantages of the treatment technology in depth, in combination with existing research. The repair methods for gas storage reservoir annulus with pressure have problems such as insufficient construction conditions, poor implementation effect, and limited types of blocking agents available. Additionally, the different working conditions and performances of the reservoir annulus are taken into account. To ensure high efficiency and cost-effectiveness, we propose a new method for treating annulus pressure. This involves repairing any damage to the cement ring, restoring the production packer’s seal, and rebuilding the integrity of the old wellbore. By doing so, we can guarantee the safety of gas storage reservoirs throughout the entire injection and production life cycle. It is important to maintain the integrity of the old wellbore to ensure the safety of gas storage during injection and extraction.

Published: November 2024

Abstract
As a result of research, it has been found that DME from natural gas (methane), oil production and oil refinery wastes and low molecular weight olefins based on it are studied. Therefore, methanol and DME, along with synthesis gas, are relevant for the improvement of the production technology of environmentally friendly motor fuels. The most active and selective catalysts for the dehydration of methanol in DME have a texture that allows the resulting DME to desorb from the surface without steric hindrance. Such “open surface” catalysts of acidic nature include mesoporous γ - Al2O3 and large-pore zeolite HU, whose promotion with H3PO4 achieves 100 % selectivity for DME formation at 88-90 % conversion of methanol. Experiments were performed by varying the amount of methanol in the CH3OH : (CO + H2) reaction mixture from 25 to 100 % by volume. In the main experiments with CO : H2 = 1:1 ratio, the linear speed of the reaction gas flow was kept constant at 3.8 ÷ 0.2 cm3 min−1, that is, the contact time was kept constant for 15.5-16 s. The reaction products were analyzed by gas chromatography.

Abstract
In order to meet the water plugging requirements of high salinity reservoirs at different temperatures, we developed three kinds of movable gel plugging and regulating agent by using salt resistant polymer as the main agent, organic chromium and organic aldehyde as the cross-linking agent, supplemented by organic stabilizers and reinforcing agents. Namely, low, medium and high-temperature and high-salinity composite movable gel plugging and regulating agent, and the formulas are 0.4% YG-100 + 0.1% YG-107,0.4% YG-100 + 0.15% YG-107+0.8% YG-103,0.4% YG-100+0.15% YG-107+0.8% YG-103 respectively. The gelling performance, thermal stability and salt resistance of the composite movable gel are evaluated. The results showed the suitable temperature is 40~126 °C, and the salinity of formation water is 260000mg/L. Seven well groups were implemented on site, and the oil pressure in the water wells generally increased. Water channeling was controlled to a certain extent, and the comprehensive water content decreased from 90.5% to 85.1%, a decrease of 5.4%. The cumulative increase in oil production was 3164 tons, and a good oil increase effect was observed.

Abstract
With the gradual deepening of petroleum exploration and development, the scale of reservoir research in oil and gas reservoirs is getting smaller and smaller, and the demand for accuracy is getting higher and higher. During the development of clastic reservoirs in the Tarim Basin, the lithology of reservoir sand bodies changes rapidly and the lateral continuity is poor, so it is difficult to effectively identify the space distribution of sand bodies by relying solely on geological logging data. In this study, combined with the advantages of logging curve for vertical identification of sand bodies and seismic data for horizontal distribution identification of reservoirs, the seismic inversion constrained geological modeling technology is proposed to realize the quantitative characterization of thin reservoir sand bodies in developed oil and gas reservoirs :①Through the analysis of sensitive characteristic curve and the extraction of targeted seismic plane attributes, the feasibility evaluation of inversion in the target area is completed, and the seismic inversion results of thin reservoirs are generated. ②Based on the results of seismic inversion simulation, a high-precision 3D lithofacies geological model is constructed by analyzing the applicability of stochastic modeling method. ③ Combined with geological cognition, the physical property characterization of 3D lithofacies geological model is realized by physical property truncated simulation method, and the spatial distribution pattern of effective sand bodies is depicted. Through the application of this method in the study area A, the problem of certain deviation between reservoir inversion driven by conventional frame model and geological cognition is solved. While the spatial recognition ability of sand bodies is further improved, the quantitative characterization of thin reservoir physical properties is realized, which provides effective technical support for the subsequent development of oil and gas reservoirs.
Doctor Mirabilis: Roger Bacon’s legend and legacy
Authors: Clegg Brian 
Published: November 2024

Abstract
Roger Bacon (1214?-1292?) has been portrayed in three ways since his death: as a figure of legend, as a Victorian scientist ahead of his time and as an overrated individual with little impact on the development of science. The evidence suggests that Bacon was in reality a significant proto-scientist, but very much a man of his time.
Newton’s disputes with Hooke and Leibniz: Institutional, scientific and personal aspects.
Authors: Iliffe Robert 
Published: November 2024

Abstract
This paper discusses the often fractious personal and academic relationships that Isaac Newton enjoyed with Robert Hooke and Gottfried Leibniz. It suggests that their disagreements operated at several levels: intellectual, methodological, institutional and personal. The disputes were related to a number of pre-existing rules of behaviour, notably those governing the correct ways to assign intellectual property and to manage disputes relating to it. Although these procedural codes concerned intellectual issues, they drew in part on etiquette in polite or genteel society more generally. The disputes were to some extent made possible by the appearance of new academies and societies, which provided new fora for disseminating results and for managing disagreements between scholars over extended distances. The presence of these intellectual institutions meant that there were novel aspects to the rules that governed these contests and indeed entirely new rules. Indeed, it was the way that the combatants attempted to get their preferred rules of engagement accepted more generally by others and the ways in which they manipulated them that conditioned the nature of their disagreements. More broadly, the capacity to engage in such contests was shaped by national pride, the ability to attract powerful support for respective causes and finally by the personalities of the individuals involved, which are perhaps best revealed in these situations.
The Big Bang versus the Steady State: Gamow, Hoyle and Ryle, rivals in cosmology
Authors: Mitton Simon A. 
Published: November 2024

Abstract
This account of the controversy concerning the Big Bang and Steady State theories contrasts the different approaches to science of George Gamow, Fred Hoyle and Martin Ryle. Einstein’s general relativity offered theoretical physicists an indispensable tool kit for making mathematical models of the Universe. Georges Lemaître made an astonishing impact in 1927 with his proposal that the expanding Universe started from a decaying super-radioactive primeval atom. Gamow refined Lemaître’s model by proposing that primordial nucleosynthesis in the early expanding Universe had formed the chemical elements. Hoyle, who by contrast had discovered the conditions under which stellar nucleosynthesis could occur via the evolution and explosion of massive stars, publicly dismissed Gamow’s cosmology as an unnecessary speculation. Hoyle, Hermann Bondi and Thomas Gold proposed the alternative steady state theory in 1948. In 1950 Ryle constructed the first radio telescope with the sensitivity to discriminate between the rival models of the Universe. Steady state cosmology survived Ryle’s first surveys of cosmic radio sources because Ryle’s data was inadequate. However results from the much improved Third and Fourth Cambridge Surveys demonstrated that our Universe had evolved. The Ryle-Hoyle debates became intensely passionate and personal. In 1965 the discovery of the cosmic microwave background radiation settled the argument in favour of the Lemaître Big Bang evolving Universe.

Richard Feynman’s talent for finding things out
Authors: Broadhurst David 
Published: November 2024

Abstract
This paper describes Feynman as an unconventional polymath primarily concerned with his own understanding of nature, having little regard for previous authorities. His curiosity, respect for experiment, ability to calculate and notable ingenuity led to important developments in quantum mechanics, quantum electrodynamics and strong interactions. In particle physics Feynman diagrams have been a mainstay of calculation for the last seventy five years. His relish for the spoken word led to renown as an educator and raconteur. His perceptions were influential in a wide range of other scientific fields, including weak interactions, gravity, superconductivity, biology, nanotechnology, algorithmic computation and quantum computers. In all of this, he held to the idea that nature has an intrinsic simplicity and beauty that permit one to find things out if only one tries hard enough.
On the role of brilliant blunders in physics
Authors: Livio Mario 
Published: November 2024

Abstract
Even the greatest scientists have made some serious blunders. This paper on brilliant blunders in physics concerns the evolution of the Earth, of stars and of the Universe as a whole. It explores and analyses major errors committed by such luminaries as Lord Kelvin, Fred Hoyle and Albert Einstein. The paper scrutinises the various types of blunders and attempts to explain how they occurred. It argues that blunders are not only inevitable, but also an integral component of the advancement of science. “Brilliant blunders” in particular can be the portals to discoveries.
‘The Service of Astronomy’: European star-gazing and its implications in the Middle Ages
Authors: Gasper Giles 
Published: November 2024

Abstract
What follows is an exploration of medieval European astronomy focussing on the twelfth and thirteenth centuries as a period of significant change in terms of technologies and learning largely via the inheritance from Greek and Islamicate astronomical thought through translation into Latin. Robert Grosseteste (c. 1170-1253) is used as a particular focal point for discussion, setting his treatise on astronomy On the Sphere in the context of his writing on related topics and those of his contemporaries. Why contemporaries should claim astronomy as the highest of the liberal arts is understood and appreciated through the use of case study and more general reflection - and so too the limits of the discipline.
Maya and Aztec astronomy: Skywatching in prehispanic Mesoamerica
Authors: Šprajc Ivan 
Published: November 2024

Abstract
The Aztecs, Maya and other Mesoamerican peoples achieved advanced knowledge of the regularities of the apparent motion of the Sun, Moon and various planets visible with the naked eye, particularly Venus. Much of this knowledge enabled orientation in space and time and was particularly useful for scheduling agricultural activities. However, since the celestial order is apparently superior to that on Earth, the phenomena observed in the sky were believed to exert influence on earthly affairs. Therefore, the exact astronomical knowledge was intertwined with religious beliefs and ritual performances, and this complex worldview had a prominent role not only in subsistence activities but also in the political ideology of the ruling class. The relevant information is contained in the imagery and hieroglyphic texts in prehispanic manuscripts or codices, mural paintings, sculpted monuments and other archaeological objects, as well as in early colonial written sources and ethnographically documented survivals of prehispanic concepts. Important data are also provided by architectural orientations, most of which were laid out on astronomical grounds, largely referring to the Sun’s positions on the horizon on certain dates.
The problem of solar energy generation: from Eddington to Bethe
Authors: Kragh Helge 
Published: November 2024

Abstract
The problem of explaining the Sun’s enormous output of heat and light was first attacked in the 1840s and soon resulted in a consensus view that solar energy was mechanical in origin. From about 1860 to 1905 the standard model was the so-called Helmholtz-Thomson contraction theory which however faced a number of serious problems. Physicists and astronomers slowly realised that the source was not mechanical but due to intra-atomic processes, either proton-electron annihilation or fusion of hydrogen into helium atoms. Both possibilities were discussed by Arthur Eddington in the 1920s, but it was only with quantum mechanics and a new picture of the atomic nucleus that quantitative models were developed. The old riddle of solar energy was essentially solved with Hans Bethe’s celebrated theory published in 1938-1939. This paper briefly reviews the developments from about 1850 to 1940.

Abstract
Exobiology is a burgeoning research field. There is a realistic prospect that in a decade or two we will have the capability to detect biosignatures – non-equilibrium atmospheric chemistry, vegetation etc. – for the nearest exoplanets. But of course what is most interesting of all would be some techno-signatures, indicating not just ‘life’, but intelligent life. This paper offers some introductory comments on this topic.

Published: November 2024

Abstract
SETI, the Search for Extraterrestrial Intelligence, is an old idea but a new science. Both inspirational and controversial, the scientific search for non-human artificial signals or communications, known as technosignatures, was pioneered by a few visionary scientists and through amazing technological advances of recent years is experiencing a renaissance that may soon answer one of the greatest scientific questions of this or any age: Are we alone? This paper describes the origins of SETI science, its rocky road to acceptance and some of the bold new ideas and explorations that are pushing the limits of our understanding of the nature of life and intelligence in the Universe.
