Authors: Wang Zhongliang 
Published: November 2024

Abstract
Electronic pressure gauge is a kind of well logging instrument for measuring downhole temperature and pressure accurately. Its high reliability and accuracy are widely used in well testing. With the oil field production entering the middle and late period, the requirement of well testing is increasing, and the daily calibration of electronic pressure gauge is put forward higher requirements. The measuring accuracy of the new electronic downhole pressure gauge is very high, but with the use of the instrument, the working time increases, the measuring accuracy of the electronic pressure gauge will gradually decline. In order to determine the effect of working time on the measuring accuracy of the electronic pressure gauge, a reasonable calibration period of the instrument is determined. Using mathematical statistics and function regression method, this paper analyzes the calibration data of the past two years, and obtains the factors that influence the measuring accuracy of the electronic pressure gauge. The results show that the measurement accuracy of the electronic pressure gauge decreases with the increase of its working time, and the change is obvious every four months. Through this conclusion, the optimal calibration period of the electronic pressure gauge can be determined, thus improving the measuring accuracy of the instrument, reducing the work intensity of the calibrator, making the downhole data more accurate, avoiding the invalidation of the measured data due to the error of the instrument, and saving manpower and material resources.

Abstract
The formation mechanism, production limits and injection-production pattern of residual oil were studied by laboratory experiment, micropore simulation and reservoir engineering. The findings indicate that when injection times increase, the displacement efficiency rises as well. The residual oil mostly remains in the pore throat, which has a radius of 10 to 50 μ m, with a mean pore throat radius of 35 μ m.. As the displacement pressure gradient increases from 0.004MPa/m to 0.012MPa/m, When the displacement ratio of piston type increases and the displacement ratio of water film flow drops, the displacement efficiency grows. The horizontal well pattern’s gradient of displacement pressure is increased by 1.5 ~ 1.7 times compared with the oriented well pattern, and the displacement efficiency is increased by 12% ~ 15%. The development of the Bohai oilfield during the ultra-high water cut stage has been informed by the aforementioned findings, forming a horizontal well joint directional well three-dimensional pattern development model, oil production rate increased from 1.3% to 2.3%, and water drive recovery rate increased from 24.5% to 38.6%, realizing efficient development in the ultra-high water cut stage, and providing reference for the development of similar oil fields.

Abstract
Fracturing truck is the key technical equipment for oil and gas production stimulation. Fracturing pump of fracturing truck is subjected to high pressure load for a long time during use. Due to the influence of many factors such as transportation and equipment aging, the performance of fracturing pump in field use is reduced and the output power is insufficient. In order to realize the on-site inspection of fracturing pump, a set of intelligent inspection and evaluation system of fracturing pump is developed. Through the establishment of the hardware test platform and the development of the software system, the intelligent inspection and evaluation system of fracturing pump with the features of one-click automatic detection, automatic analysis of performance indicators, intelligent prediction and maintenance of health status is realized. The system can support the static pressure test, water power test and overpressure protection test of 140MPa ultra-high pressure fracturing pump. Experimental tests show that the test accuracy of the equipment can effectively meet the detection and evaluation needs of the field fracturing truck, ensure the normal function through static pressure and water power detection, and determine the safety of the equipment through overpressure protection detection, which greatly improves the effect and efficiency of fracturing operations.

Published: November 2024

Abstract
Deep carbonate reservoirs present significant hurdles for reservoir stimulation due to extreme temperatures and rapid acid-rock reactions. The dense adsorption layer has the ability to postpone the interaction between rock and hydrogen ions, which is crucial for lowering the acid rock reaction rate. Based on the surfactant and film-forming agent’s synergistic impact, the retarding agent SH-1—which has the ability to generate a dense adsorption film on the surface of rock samples—was chosen for this study. After adding synergist and corrosion inhibitor, a new type of high temperature resistant adsorption type retarding acid system ’ 0.9% SH-1 + 20% HCl + 0.1% synergist + 1.5% corrosion inhibitor ’ was developed. The retarding performance of the retarding acid system at high temperature and various parameters of acid rock reaction kinetics were studied. The results show that the new adsorption-type retarded acid system can achieve good retarding effect at high temperature and ultra-high temperature, and the retarding rate is 90 % at 180 °C. In comparison to traditional hydrochloric acid, the new adsorption-type retarded acid exhibits a lower hydrogen ion mass transfer rate and a higher acid-rock reaction activation energy. These differences can effectively lower the acid-rock reaction rate. Additionally, an examination of the etching morphology reveals that the retarded acid is more easily etched along the cracks leading to the deep core. The novel adsorption-delayed acid offers excellent retarding power, high temperature resistance, and minimal damage. Consequently, it has certain reference value for the study of acidification transformation of ultra-high temperature deep carbonate reservoirs.

Abstract
Carbon Capture, Utilization and Sequestration (CCUS) is a method of burying CO2 captured in various ways into the reservoir and extracting the remaining oil from the reservoir. It is one of the important methods to reduce carbon emissions and achieve carbon neutrality in the next few decades, and it is also considered to be the most economical and effective method to slow down the greenhouse effect. It is very important to study the influence of reservoir heterogeneity on CO2 storage and oil recovery in order to make CCUS scheme store more CO2 and recover more remaining oil. Firstly, the numerical simulation model of reservoir is established in this paper. Its injection-production mode is gas injection in vertical wells at the top of the reservoir at a fixed gas injection rate, and oil production in horizontal wells at the bottom of the reservoir at a fixed pressure. Secondly, the distribution of reservoir porosity and permeability is designed, and four reservoir models are established: homogeneous reservoir, heterogeneous reservoir, positive rhythm heterogeneous reservoir and reverse rhythm heterogeneous reservoir. Finally, the effects of four reservoir models on CO2 storage and oil recovery are studied, and the migration law of CO2 is comprehensively analyzed according to the characteristics of reservoir pressure distribution. The reverse rhythm reservoir has the best CO2 storage effect, and the positive rhythm reservoir has the highest oil recovery. That is, when burying is the main method, the reverse rhythm heterogeneous reservoir is preferred; When oil displacement is the main method, positive rhythm reservoir is preferred. Among the four homogeneous or heterogeneous reservoirs, the migration law of CO2 in reservoirs is quite different, mainly due to the influence of reservoir heterogeneity. CO2 preferentially migrates from the dominant channels in the reservoir, but regardless of the reservoir type, the molar fraction of CO2 at the top of the reservoir is the highest. In addition, the CO2 invasion of four kinds of reservoirs in different stages of caprock is analyzed and its safety is analyzed. This study provides an effective reference for the establishment of numerical simulation models of different types of heterogeneous reservoirs, the migration characteristics of carbon dioxide in reservoirs and the effective operation and evaluation of CCUS scheme.

Abstract
Gas lift is a widely employed artificial lift method in the oil and gas industry, with the potential to significantly impact oil recovery from reservoirs. This study investigates the effect of gas lift on the oil drainage area within reservoirs, aiming to enhance our understanding of its role in reservoir management. Using advanced reservoir engineering and simulation techniques, the research explores the dynamics of gas lift and its influence on the accessibility of hydrocarbon resources.
The study provides a comprehensive analysis of gas lift parameters, including gas injection rates, depths, and configurations, and their collective impact on the drainage area. It also considers the interplay between gas lift operations and reservoir characteristics such as permeability, porosity, and fluid properties.
Findings from this study reveal that gas lift can effectively expand the drainage area by reducing bottomhole pressures and facilitating the movement of oil within the reservoir. This expansion enables the recovery of hydrocarbons from previously untapped regions, resulting in improved oil production. The research underscores the importance of optimizing gas lift design to maximize reservoir performance.
Additionally, the study addresses operational challenges associated with gas lift, including gas allocation, injection optimization, and equipment reliability. It provides insights into the economic and operational considerations of gas lifts, offering valuable recommendations for reservoir management.
The outcomes of this research contribute to a deeper understanding of how gas lift influences the oil drainage area in reservoirs, providing valuable insights for reservoir engineers, operators, and industry professionals involved in oil production. This knowledge supports informed decision-making to optimize oil recovery, reservoir performance, and the efficient use of gas lift technologies.

Abstract
Metal casings shield the cathodic protection current and detection signals of buried metal pipelines, making the corrosion protection and detection technology of pipelines at the casing one of the challenges for safe operation and integrity evaluation of pipelines. This paper uses the primary current distribution physics interface in the COMSOL Multiphysic simulation software to study the effects of the coating quality of the casing and pipeline, the installation of sacrificial anodes in the casing, the conductivity of the electrolyte, and defects in the pipeline coating in the casing on the pipeline potential. The influence of distribution. The results show that: The coating quality of the outer surface of the casing and the pipe inside the casing has a great influence on the cathodic protection potential of the pipeline. The better the coating quality, the more negative the cathodic protection potential is, and the less cathodic protection current required by the pipeline, so the power consumption of the forced current law is reduced, and the service life of the sacrificial anode is longer. Installing sacrificial anodes in the casing has a positive effect on the cathodic protection of this special pipe section. The conductivity of the electrolyte in the casing has a certain impact on the cathodic protection potential of the pipeline. When the conductivity of the internal electrolyte is greater, the protective potential of the pipeline becomes more negative. However, impurities such as soil, groundwater, and silt make the pipeline more susceptible to corrosion, so keeping the annular space relatively dry is an important prerequisite for anti-corrosion. When there is a coating defect on the inner and outer pipes of the casing, the potential at the damaged point will have a potential peak. The larger the potential peak difference, the more serious the coating defect is.
Birds of passage: Rudolf Peierls and Dick Dalitz in Oxford
Authors: Hey Tony 
Published: November 2024

Abstract
This paper traces the different routes that Rudolf Peierls and Dick Dalitz travelled on their way to being the founding members of a new Department of Theoretical Physics in Oxford. Peierls had had the good fortune to meet all of the originators of modern quantum mechanics in Europe and had been able to apply the new theory to many areas of physics. At Birmingham with Otto Frisch he wrote the famous Frisch-Peierls Memorandum which showed that it was possible to develop an atomic bomb. Dalitz had a shorter route to Oxford and worked with Peierls at Birmingham and Hans Bethe at Cornell before rejoining Peierls in Oxford after seven years in Chicago. His pioneering work on both the τ-θ puzzle and on the constituent quark model are then briefly described. The efforts of both Rudolf and Genia Peierls to create a ‘Bohr extended family’ model for his department in both Birmingham and Oxford are described, along with some observations about their style of theoretical physics research as ‘phenomenologists’.
The bright side of the Moon: The historical journey of our tidally locked satellite
Authors: Pumfrey Stephen 
Published: November 2024

Abstract
The paper discusses a major shift in the (Western) science of our Moon. It reconsiders well-known developments, as the Aristotelian concept of distinct celestial and terrestrial worlds in which the Moon was one of seven perfect planetary spheres gave way to our modern view of a very Earth-like body, even endowed at one stage with oceans and continents. It examines the impact of pre-telescopic and telescopic observations in the period 1560 to 1660, notably those of Galileo Galilei and William Gilbert. Its new perspective is to present the strong evidence that supported the idea of the Moon as a planet. In large part this was because it is now known that aspects of the Moon’s orbit are unusual compared with the multiplicity of “moons” in the Solar System. It argues that a major reason was Aristotle’s influential argument for the theoretical impossibility of lunar libration. It concludes with the extraordinary work of William Gilbert (1544-1603) who, it is argued, was the true discoverer of libration because Galileo, who is often credited with it, failed to grasp the necessary dynamics of lunar motion. Notwithstanding, both played crucial roles in the emerging conception of our Moon as “another Earth”. Human activity is now degrading both bodies.

Abstract
This paper briefly presents the dark matter problem and the many ongoing attempts to solve it. After a brief introduction to the history of dark matter, the paper reviews the relevance of this mysterious component of the Universe in modern cosmology and it discusses the implications of the absence of evidence for dark matter in all experiments carried out in the past four decades. It then argues that a new era has started in the search for dark matter with much astronomical data about to become available and a new generation of gravitational wave experiments about to start operations. Finally, it stresses that the field of dark matter searches is completely open and that there are exciting opportunities for the next generation of scientists to develop new ideas and to make ground-breaking discoveries.
Philosophical questions about the arrow of time
Authors: Deng Natalja 
Published: November 2024

Abstract
Philosophical questioning about the arrow of time is an active research area, but one with a long and industrious history in both physics and philosophy. This paper begins by distinguishing between a puzzle about the origin of the thermodynamic time asymmetry and questions about whether the thermodynamic time asymmetry can itself explain other temporal asymmetries. It goes on to give a brief description of how the puzzle arises in classical mechanics, followed by an interlude on whether and how quantum mechanics might change the situation. Finally, it takes a closer look at the puzzle in terms of statistical mechanics and one proposed solution.
A very brief history of colour metaphysics
Authors: Müller Olaf 
Published: November 2024

Abstract
These are five playfully pessimistic meditations on the metaphysics of colour, arguing that metaphysical thinking does not fit well with the beautiful universe of colours: Neither Platonism nor relativism nor reductionism nor the distinction between primary and secondary qualities nor the denial of the existence of some colours at the expense of others offers convincing ways of dealing with the phenomena of colour. In the final, sixth meditation the standard analysis of magenta is challenged with some unorthodox ideas that can be traced back to Johann Wolfgang von Goethe’s colour research.

This paper delves into the profound influence of light-based technologies on society, culture and various scientific fields by exploring the understanding of the electromagnetic spectrum and highlighting seminal inventions developed from our understanding of it. Historically the visible spectrum served as humanity’s primary interface with light, giving rise to basic tools like the magnifying glass and the prism. However, the 19th and 20th centuries heralded groundbreaking revelations about the broader spectrum—discovering rays invisible to the naked eye from gamma rays to radio waves. This understanding stimulated technological revolutions, profoundly altering our daily lives and global infrastructures. Prominent inventions such as the radio, televison, X-ray machines, optical fibres and lasers, each harnessing distinct parts of the spectrum, have propelled advancements in communication, medicine, materials and information technology. Additionally light technologies have been pivotal in critical breakthroughs in quantum mechanics, relativity and astrophysics, deepening our understanding of the Universe. Light-based technologies rooted in our evolving comprehension of the electromagnetic spectrum have indelibly impacted our world. From fundamentally altering industries to reshaping daily rituals the influence of light is a testament to humanity’s enduring quest for progress and understanding.
