Abstract
The chemical composition of an extrasolar planet is fundamental to its formation, evolution, and habitability. In this study, we explore a new way to measure the chemical composition of the building blocks of extrasolar planets by measuring the gas composition of the disrupted planetesimals around white dwarf stars. As a first attempt, we used the photoionization code Cloudy to model the circumstellar gas emission around white dwarf Gaia J0611−6931 under some simplified assumptions. We found that most of the emission lines are saturated, and the line ratios approach the ratios of thermal emission; therefore, only lower limits to the number density can be derived. Silicon is the best-constrained element in the circumstellar gas, and we derived a lower limit of 1010.3 cm−3. In addition, we placed a lower limit on the total amount of gas to be 1.8 × 1019 g. Further study is needed to better constrain the parameters of the gas disk and connect it to other white dwarfs with circumstellar gas absorption.

time-series photometry for 212 RR Lyrae (173 fundamental-mode, 24 first-overtone, and 15 mixed-mode variables) and five Anomalous Cepheids in Draco dSph are presented and used to derive their period–luminosity relations at NIR wavelengths for the first-time. The small scatter of ∼0.05 mag in these empirical relations for RR Lyrae stars is consistent with those in globular clusters and suggests a very small metallicity spread, up to ∼0.2 dex, among these centrally located variables. Based on empirically calibrated NIR period–luminosity–metallicity relations for RR Lyrae in globular clusters, we determined a distance modulus to Draco dSph of μ

Our recommended ∼1.5% precise RR Lyrae distance, D

Spontaneous thrombosis of type II vein of Galen aneurysmal malformation: a case report
Authors: Bogovski Stefan , Sirakova Kristina , Sirakov Stanimir 
Published: April 2024

Vein of Galen malformations (VGAMs) are rare and complex congenital brain vascular anomalies that pose significant diagnostic and treatment challenges. The natural history of this type of vascular anomaly is very poor, with many patients succumbing to complications such as congestive heart failure, hydrocephalus, and brain parenchymal injury. Although the clinical course of most VGAMs was considered unfortunate, with meticulous imaging, a group of lesions with a more placid presentation and course can be identified.
We present a case of spontaneous thrombosis of VGAM where no embolization or surgical repair was attempted, with excellent clinical outcomes.
This case also highlights the possibility of spontaneous thrombosis in VGAM, even in the absence of clinical symptoms, and emphasizes the importance of a regular imaging follow-up in patients with known vascular malformations.

Authors: Chim Paul Roselé 
Published: April 2024

La gouvernance joue un rôle essentiel dans le fonctionnement et l’amélioration de la performance des entreprises en définissant proprement leur structuration pour s’adapter aux changements de l’environnement économique. Penser que toutes les sociétés pourraient appliquer des règles de gouvernance identiques serait perturbant, voire déstabilisant pour un système qui est par ailleurs globalement doué à rechercher toujours plus de cohérence et d’efficacité. Dans les discussions sur la gouvernance et la performance, le dirigeant occupe une place majeure dans le processus conduisant à la création des richesses. Ce papier se focalise à étudier la gouvernance d’entreprise à travers un échantillon de 22 entreprises de taille assez variée qui recouvre l’ensemble de l’économie de la Guyane française.
L’effectivité des lois sur la sortie de l’indivision successorale en Outre-mer atlantique

Published: April 2024

40 % du foncier serait encore paralysé par des indivisions successorales en Guadeloupe ou en Martinique. Cette problématique n’est pas propre aux Antilles, elle se retrouve aussi dans d’autres territoires ou collectivités d’Outre-mer (la Réunion, Mayotte…), mais aussi la Corse. Ainsi, ces dernières années, les régions ultra-marines ont bénéficié d’une inflation législative ayant pour finalité de sortir de ces indivisions complexes. Plusieurs dispositions transitoires spécifiques aux Outre-mer ont été adoptées. Ensuite, la loi dite « Letchimy » du 27 décembre 2018 s’est donné pour objectif de lutter contre les situations d’indivision inextricables et relancer la politique du logement. Elle vise à faciliter la sortie des indivisions successorales de plus de 10 ans en Outre-mer. Il s’agit d’un dispositif expérimental pour une période de dix ans qui permet au notaire de partager les biens dès lors qu’une majorité simple des indivisaires est atteinte au lieu de l’unanimité requise en droit commun. Cependant, les notaires qui sont les chevilles ouvrières du dispositif font montre de nombreuses réticences. Comment l’expliquer ? L’effectivité de ces lois est pourtant une question sensible dans la mesure où elle permet d’apprécier, d’évaluer la portée de ce mouvement législatif. Il convient dès lors de comprendre ce qui fait obstacle à la mise en application du dispositif afin de tenter de trouver des solutions pour débloquer ces situations.

Abstract
The intelligent well completion in Brazilian Pre-salt wells poses challenges for workover operations. This paper describes the main challenges faced and the new methods employed for workover in this scenario. Since acid stimulation caused severe fluid losses in these wells, which are equipped with integral intelligent completion [1 – SPE-195935], the removal of the production string brings several complications. Through tubing operations, such as the use of nippleless plug set, feedthrough packer release, and mechanical cutting of the production string, were conducted. The removal of the completion string was done in a single trip, with fluid losses sustained and well safety concerns considered. The use of Managed Pressure Drilling (MPD) techniques was employed and required modifications to existing tools. A thorough planning for the new completions was developed to safely return the well to production. The successful application of these techniques in a workover operation in 2023 demonstrated its suitability for high complexity and high productivity wells, such as those found in the Brazilian Pre-salt, potentially benefiting the entire industry.
Monitoring Subsea CCS: Following the CO2Molecules From Top to Bottom and Ensuring They Stay in the Rock
Authors: Wiltshire M. , Roux P. 
Published: April 2024

Abstract
This paper evaluates technologies and available methods for the surveillance of flow in subsea CO2 injection systems, going from the subsea infrastructure to the injection wells, into the reservoir, and then back to the seafloor. Considerations and provisions required in the subsea system to accommodate certain surveillance technologies are highlighted. In this paper, the potential path taken by CO2 molecules are followed through a subsea storage system, with leak detection and plume surveillance in mind.
Feasibility and opportunities for using monitoring methods and leak detection technologies were assessed by utilizing an assessment matrix which summarises the various advantages and disadvantages of plume monitoring technologies and leak detection methods. The following aspects were assessed for each technology: 1. Technical feasibility; 2. Technology Readiness Level (TRL) and development required; 3. Impact of the solution on the subsea system (e.g. field architecture, power and communication); 4. Relative costs; 5. Schedule (e.g. added risk due to development required).
Leak detection methods having unknown efficacy and limited research in CO2 applications were screened out. Those methods which have been field tested for CO2 service or currently under lab testing were advanced to a second stage of screening by product specifications to further consider their integration into the subsea injection system design. Passive acoustic technology was found to be the best suited for detection across subsea infrastructure as it covers a desirable detection radius at the lowest cost. Screening of plume monitoring methods showed benefits and drawbacks of each method evaluated; the review concluded that different technologies should be used at different stages of a subsea CCS project. Near well bore, CO2 migration monitoring can be performed using Vertical Seismic Profiling (VSP) as it yields a high-resolution image in the vicinity of the well. When the plume eventually outgrows VSP's radius of investigation, a sparse acquisition strategy can later be used to verify conformance of reservoir model's plume migration at strategic locations. Finally, leak detection tools such as an AUV with side scan sonar and a chemically degraded trigger and beacon could be used for leakage from the reservoir through the seabed and legacy wells respectively.
This paper provides a novel integrated view of CO2 escape paths, bringing together topics around CO2 leak detection from subsea injection equipment, sub-surface plume monitoring and leakage from reservoir through the seabed. The results of this research can benefit CCS projects in the concept phase influencing the design of subsea infrastructure to accommodate monitoring methods, thus guiding technology and risk assessments to support a Measurement, Monitoring and Verification (MMV) plan.

AbstractDecommissioning decision-making is an integral and complex process in various industries, such as nuclear power plants, oil and gas facilities, and industrial manufacturing plants. The planned service life of many offshore oil and gas facilities is coming to an end. Decommissioning these facilities has emerged as a crucial task due to significant and uncertain expenses, high operational risks, potential social consequences, and environmental considerations related to the marine ecosystem. This paper proposes an evolving methodology to assist a sustainably oriented decision process for decommissioning the subsea infrastructure of offshore oil and gas facilities.Decision-making plays a crucial role in the search for a balance between the concerns of stakeholders, such as oil and gas companies, government bodies, environmental protection organizations, marine and coastal environmental users, and local communities. The decision problem is often complex since, most of the time, no ideal option is available to satisfy all criteria. Decision-makers can employ advanced approaches to address this problem, such as the multi-criterion decision analysis presented in this work. This methodology improves the decision-making process by ranking the various options for decommissioning subsea oil and gas assets. The model considers six criteria: Safety, Environment, Waste Management, Technical, Social, and Economic. Multiple decommissioning alternatives are compared, where groups of structures with similar technical and environmental characteristics are identified and analyzed together.The paper summarizes the application of this methodology in decommissioning different fields off the Brazilian coast, demonstrating excellent performance in helping the decision-making process.The methodology proposed addresses the growing concern about properly disposing of the decommissioned materials in an environmentally responsible manner with guidance from life-cycle assessment methods. Furthermore, attention is given to sustainability-related concerns regarding emissions generated during decommissioning operations. A set of tools was developed to help the stakeholders to have a better understanding of the results. The methodology contributes to reducing the subjectivity of the decision by assisting a project that is still conceptual to make decisions based on solid foundations raised through various databases and specialist knowledge.

Abstract
TotalEnergies is committed to the goal of sustainability as it targets to achieve NetZero by 2050. One of the levers to carbon intensity reduction is to reduce direct emission from our portfolio and developing carbon sinks. Hence, the plan is to provide carbon storage services which would store equivalent of 50-100Mt/year of CO2 (TotalEnergies, 2023). To realize this objective, the logical step is by building capacity, in terms of skills and projects, to adapt to the new requirements of CO2 injection.
This ambition requires developing viable and sustainable surface and downhole equipment design which can meet the challenges of CO2 injection. Our focus is the case of CO2 that is transported in dense phase to the well and then injected into a highly depleted reservoir. Among the challenges associated with the dense phase CO2 injection into a depleted reservoir is the question of compatible completion strings, tubing connections and Downhole Safety Valve (DHSV); which form the primary well barrier, capable of handling potentially extreme low temperatures and rapid swings of temperatures associated with transient conditions of CO2.
Thus far, we have proposed credible load cases for completions stress analysis and developed a methodology / guideline for completions design in highly depleted reservoir. Today, we routinely apply it to every project in focus; to incorporate CO2 sequestration in the project development plans.
The results of this methodology clarify the specific need(s) for completions design and associated equipment qualifications for CCS applications in highly depleted reservoir environment.
