Abstract
Gamma-ray emission in the MeV–GeV range from explosive cosmic events is of invaluable relevance to understanding physical processes related to the formation of neutron stars and black holes. Here we report on the detection by the AGILE satellite in the MeV–GeV energy range of the remarkable long-duration gamma-ray burst GRB 221009A. The AGILE onboard detectors have good exposure to GRB 221009A during its initial crucial phases. Hard X-ray/MeV emission in the prompt phase lasted hundreds of seconds, with the brightest radiation being emitted between 200 and 300 s after the initial trigger. Very intense GeV gamma-ray emission is detected by AGILE in the prompt and early afterglow phase up to 10,000 s. Time-resolved spectral analysis shows time-variable MeV-peaked emission simultaneous with intense power-law GeV radiation that persists in the afterglow phase. The coexistence during the prompt phase of very intense MeV emission together with highly nonthermal and hardening GeV radiation is a remarkable feature of GRB 221009A. During the prompt phase, the event shows spectrally different MeV and GeV emissions that are most likely generated by physical mechanisms occurring in different locations. AGILE observations provide crucial flux and spectral gamma-ray information regarding the early phases of GRB 221009A during which emission in the TeV range was reported.
Organomineralization of dolomite in hypersaline microbial mats from Qatar sabkhas visualized by TEM &amp; STXM

Published: October 2023

Deep insight into the low-temperature mineralization mechanism of dolomite in sediments has remained elusive. This issue is popularly termed “The Dolomite Problem” due to its multifactorial nature. Dolomite has been observed to mineralize in the exopolymeric substances produced by microbial mat communities (Bontognali et al. 2013), where productivity is high. One working hypothesis suggests that degrading organic matter in hypersaline environments releases the necessary component ions, increasing saturation with respect to dolomite (DiLoreto et al. 2019, Dupraz et al. 2009, Petrash et al. 2017). Other models suggest a dissolution-reprecipitation reaction of calcite to dolomite (Rivers 2023). High-resolution micro-spectroscopy techniques (such as transmission electron microscopy, TEM; and scanning transmission X-ray microscopy, STXM) can be used to determine chemical changes in crystals nucleating in a matrix, however to date very little studies have focused on observing dolomite mineralization at the nano-scale. The present study investigates microbial mats collected from hypersaline salt flats in the Persian gulf at micro- to nano-meter scales using high-spatial and -energy resolution TEM (Thermo Scientific Talos 200X at the Canadian Centre for Electron Microscopy) and STXM (PolLux Beamline at the Swiss Light Source at Paul Scherrer Institut), specifically to see changes in carbonate mineralization due to interactions with organic matter. C, Ca and O elemental maps of carbonate crystals were obtained with EDXS (energy-dispersive X-ray spectroscopy) in TEM. These crystals were also indexed by SAED (selected area electron diffraction in TEM). Fine spectral signatures (near-edge X-ray absorption fine structures, or NEXAFS) at the C K-edge (280-290 eV) and Ca L2,3-edge (344-356 eV) in STXM were used to determine the chemical identity of carbonate minerals and surrounding organic matter of the microbial mats.
The results of the study show that dolomite nucleates in close association with the organic matter of the mats, where degradation is highest (defined in our adjacent study as the increase in C:N ratio). In TEM, polycrystalline dolomite is seen mineralizing in the matrix of the microbial mat organic material (Fig. 1). In STXM, the identity of the carbonate mineral changes from calcite on the outside to dolomite on the inside of the microbial mat particle (Fig. 2). In addition, our microsensor observations of elevated H2S concentrations, surface oxygenation from oxygenic phototrophy, high reduction potential, high organic carbon, high Mg:Ca ratio and high organic matter degradation (by C:N ratio) in each of the studied microbial mats confirms that the ideal dolomite mineralization conditions according to models of the dolomite problem are present in each case.

L’ordonnance Cadre Eau impose le cout-vérité de l’eau conformément au principe du pollueur-payeur. En pratique, les consommateurs d’eau – domestiques et non domestiques – bruxellois sont les principaux contributeurs au financement de la lutte contre les inondations, de la collecte et de l’épuration des eaux présentes dans le réseau unitaire d’égouts bruxellois. Cependant, environ la moitié des eaux résiduaires sont des eaux de pluie et des eaux claires parasites qui ne sont pas liées à la consommation d’eau. Les consommateurs ne devraient donc pas être mis à contribution pour les couts qu’elles engendrent en vertu du principe du pollueur-payeur. Nous estimons que 20 % de la facture d’eau des consommateurs est indument à leur charge et examinons comment ces montants pourraient être financés autrement.

Abstract
This article aimed to analyze the relevance of wind and solar energy for the supply of artificial lifting systems on offshore platforms in the Brazilian equatorial region. The scope encompassed a detailed technical and environmental assessment, with an emphasis on the integration of a 10 MW floating photovoltaic power (FSPV) system to meet the demand for 10 pumps. In addition, the study sought to evaluate the potential for solar power generation in the region, considering the abundant global horizontal solar radiation (GHI).
The methodology employed involved a thorough evaluation of the energy required for the artificial lifting system, using nine steps as described by Centrilift. For the analysis of solar power generation, the System Advisor Model (SAM) developed by the National Renewable Energy Laboratory (NREL) was used. The meteorological data and wind potential were obtained from measuring stations of the National Institute of Meteorology (INMET). Through SAM, FSPV performance has been carefully modeled, considering different scenarios to determine the viability of the power solution.
The results obtained highlighted the high viability of the 10 MW FSPV system to meet the energy demand of the 10 artificial lifting pumps. The simulations carried out in the SAM indicated a significant annual generation of electricity, with a high supply capacity and a good performance index, ensuring an adequate and sustainable energy supply over time. In addition, the analysis revealed the promising potential of solar power generation in the equatorial region, consolidating FSPV as the most appropriate option and with the best prospects for offshore platforms in this location.
This study provides valuable information by highlighting the feasibility of floating solar energy as a viable energy solution for offshore platforms in the Brazilian equatorial region. The integration of the FSPV system was thoroughly evaluated, demonstrating the benefits of the abundant availability of solar radiation, as well as the modulation and scalability of the systems. In addition, the environmental impacts associated with both energy sources were identified, underscoring the importance of mitigating any possible negative effects. The study presents an in-depth and reasoned analysis, offering valuable guidance for future renewable energy projects in regions of similar characteristics.
Coming Innovation for the Provision of Remote, Reliable, Unattended Power Generation and Data Communications for Deep-Water Applications: The Autonomous Offshore Power System
Authors: Lesemann A. R. 
Published: October 2023

Abstract
The paper describes the autonomous offshore power system (AOPS) — an innovative power and data communications system — that is being prepared for introduction to remote, deep-water applications. This paper consolidates technical and market information about the AOPS presented in prior OTC papers and contextualizes it for the Brasilian offshore upstream oil and gas sector.
The AOPS is currently being introduced into shallow-water environments for support of mobile and static assets, such as data-gathering systems, surface and subsea robotics, and operating equipment for the offshore energy, defense, security, and research markets. The AOPS uses multiple energy resources (ocean energy and solar) and storage technologies (rechargeable batteries and pre-charged fuel-cells) to provide ultra-reliable energy supplies and data communications in remote, offshore locations. An AOPS can provide primary, redundant, or emergency power and data communications capabilities. For instance, an AOPS can provide first power to a greenfield development, enable 24/7 leak detection monitoring and reporting, provide permanent in-situ power for a brownfield upgrade, or avoid the need for replacement of a failed umbilical to a stranded asset.
Innovative AOPS technologies are currently in pilot testing for shallow-water depth sites in temperate climate zone locations. Advancements currently underway to various AOPS technologies will deliver a system suitable for deep-water applications in tropical climate zone locations. The purpose of an AOPS is to reduce the cost, complexity, and carbon-intensity of offshore activities by replacing topside vessels and power and data umbilicals. An AOPS can also enable provision of new hardware and services not techno-economically possible before.
The paper will highlight the various AOPS technologies under development, the variety of use cases and applications an AOPS is suited for, and how an AOPS can reduce the cost, complexity, and carbon-intensity of deep-water operations in the Brazilian oil and gas sector.
Offshore Pipeline Case-Study: State-Of-The-Art Comparison Between Different ILI Technologies for Challenging Metal Loss Diagnosis and Remaining Lifetime Assessment

Published: October 2023

Abstract
This paper describes the history of an offshore pipeline that failed from an internal corrosion defect that was not detected by the MFL-A technology. After the failure, the pipeline was inspected with different technologies such as MFL-A, MFL-C, IEC, and Ultrasonic Wall Thickness Measurement. The authors discuss different detection capabilities, inspection variables, data analysis process, inspection results, and integrity management.
Internal corrosion is one of the main failure mechanisms of rigid pipelines. Accordantly to the U.S. Department of Transportation [3], between 1998 and 2017 approximately 12% of pipeline incidents were caused by internal corrosion. To detect, measure and evaluate the corrosion anomalies, the ILI technologies are the most accurate approach to define the maximum operating pressure and manage their integrity [13]. The industry offers different types of technologies, such as Ultrasonic Wall Thickness Measurement, Axial and Circumferential Magnetic Flux Leakage, and Internal Eddy Current. Corrosion defects offer different levels of complexity for detection and sizing depending on the nature of the corrosion phenomenon and its morphology. All technologies have advantages and limitations; therefore, it is important for operators to identify the priorities to select the most appropriate technology based on needs.
The decision of which technology or combination of technologies should be used is the main task and responsibility of the Integrity Manager, and involves technical, commercial, and operational factors. The paper proves that some ILI technologies are not able to correctly identify and measure specific nature and geometry of corrosion anomalies. It intends to create a guideline for operators to correctly choose the ILI technology and be able to properly manage the integrity of rigid pipelines, defining its maximum operating pressure and evaluating the necessity for repair.
The authors intend to share with the industry the technical particularities in the data comparison from the last two inspections carried out to pipeline with Ultrasonic Wall Thickness Measurement, with special focus on challenging anomalies due to its location, geometry, and size. This Offshore pipeline case is turned public to share the knowledge gathered through many inspections and engineering analysis conducted during life extension assessment of the pipeline.

Abstract
FPSO platforms have traditionally employed conservative designs for their electrical systems, resulting in lower load conditions than originally anticipated during the design phase. This work proposes a machine learning framework for data driven FPSO electrical systems design and simulation, with several machine learning and data analysis routines being implemented. The user experience design was done with the objective of the tool being easy to understand and use by engineering teams responsible for management level decisions. To achieve this an iterative development process was employed using target users’ feedback, with the final automatic regression functionality achieving an average mean absolute error of 0.87% per platform on validation data. Some features, such as the clustering functionality were specifically requested during the development, while others, such as the automated data preprocessing pipeline, were designed to minimize the need for user interference while maintaining a high-quality dataset for the user to work with. Developed in the background of a partnership between a research team at UFF and Petrobras, the framework was found appropriate and is currently at an early adoption phase by relevant teams at Petrobras.

Published: October 2023

Abstract
Production from heavy oil reservoirs is a challenging task and needs special design. In this study, oil well production was maximized using nodal analysis for a field of study. The optimum tubing and flow line sizes are selected by means of pressure traverse. The wellhead pressures and choke sizes were computed by finding the inflow and outflow of the flow line. Several reservoir parameters for the purpose of observing the effects of pressure depletion were investigated. Initially, fluid description, flow type, type of artificial lift, well type whether offshore or onshore, and well completion is selected. PVT data are entered, and the matching process requires some parameters such as reservoir temperature, with the corresponding pressure to be produced. Then, IPR is selected and found depending on the reservoir data. The calculated data should be matched with measured data using VLP/IPR quality check to make sure that the models emulate the actual well data. If there is no matching, entered PVT data should be checked until matching is found. If performance is accepted, the operating point is found at the intersection of IPR and VLP and that is before optimization. The optimal values are entered into the design and computing the operating point after modification if results are not as expected, the modification process is checked again until reaching satisfactory outcomes and this project's goals are met. The results of the study revealed that there was no fluid flow before the gas lift or ESP operation. All the methods studied revived well-X. The significant result was the ability of GL which was 1509 2708 STB/ day, and ESP has achieved the highest oil production of 2708 STB/ day. The economic range was found to be [(2-4.2), (2- 3.6), and (1-2.7)] MMSCF/D for CH4, N2, and CO2 respectively. That led to an economic injection rate of 3, 3.4, and 2.4 MMSCF/D for CH4, N2, and CO2 correspondingly, and for ESP is 180,229.4$ which is the highest revenue compared with the GL method. Finally, the findings contribute to oil and gas by considering greenhouse gasses. Also, it recommends the possibility of using another gas injection type and another artificial method, then compared with these results to find the best method for heavy oil.
A New Delta-Transient Method for Real-Time Permeability and Skin Prediction in Multi-Layered Oil Reservoirs Near Sealed Zones

Published: October 2023

Abstract
Permeability and skin prediction in multilayered reservoirs near sealed boundaries during production are essential for the appropriate oilfield development. This work proposes a new method for obtaining the transient individual layers’ permeability, k(t) and skin, S(t) data in a well near a no-flow boundary (sealing fault case) by combining a production logging tool (PLT) and a mathematical formulation that deals with equivalent rock and fluid properties, e.g., transmissibility, pressure drop, and oil flow rates. New fault parameters βf and δf arise in the logarithmic approximation of the line-source solution Ei(r, t) to represent the role of the fault on the real-time permeability and skin responses.
The mathematical model presented in this paper is based on the equivalent representation of a system composed of a multilayered reservoir near a no-flow boundary that considers each unsteady-state individual layer property for the formulation. A new reservoir layer parameter named Delta-Transient for sealed zones is derived, and it deals with the unsteady-state permeability and skin effect as a function of the equivalent oil flow rate and pressure gauge real-time data. This paper shows that this parameter comprises the sum of the infinite-acting-radial-flow and the well-sealing fault terms. The calibration of the model developed in this study was performed using a numerical simulator named Saphyr, and the results presented convergence. An error analysis was also presented and demonstrated that the method is sensitive to flow rate and pressure variations.
The proposed model is applicable to formation evaluation and reservoir engineering to predict unsteady-state permeability and skin behavior on carbonates reservoirs due to the lack of adequate methods to provide reliable information. This practical field application, combined with the model's simplicity, constitutes the advantages of the model addressed in this paper.
