Le partage des données vu par les chercheurs : une approche par la valeur
Authors: Rebouillat Violaine 
Published: March 2022

Le propos de cet article porte sur la compréhension des logiques qui interviennent dans la définition de la valeur des données de la recherche, celles-ci pouvant avoir une influence sur les critères déterminant leur motivation au partage. L’approche méthodologique repose sur une enquête qualitative, menée dans le cadre d’une recherche doctorale, qui a déployé 57 entretiens semi-directifs. Alors que les travaux menés autour des données sont focalisés sur les freins et motivations du partage, l’originalité de cette recherche consiste à identifier les différents prismes par lesquels la question de la valeur des données impacte la motivation et la décision de leur partage. L’analyse des résultats montre que, tous domaines confondus, la valeur des données reste encore cristallisée autour de la publication et de la reconnaissance symbolique du travail du chercheur. Les résultats permettent de comprendre que la question du partage est confrontée à un impensé : celui du cadre actuel de l’évaluation de la recherche, qui met l’article scientifique au cœur de son dispositif. Ce travail contribue donc à montrer que l’avenir du partage des données dépend des systèmes alternatifs futurs d’évaluation de la recherche, associés à la science ouverte.
Imaginer la possibilité de la guerre nucléaire pour y faire face
Authors: Pelopidas Benoît 
Published: March 2022

Comment les citoyens peuvent-ils se figurer la possibilité de la guerre nucléaire pour y faire face politiquement ? Pour répondre à cette nouvelle question, cette intervention s’inscrit dans la lignée des travaux sur la culture populaire visuelle et avance trois arguments. D’abord, elle réaffirme le rôle essentiel de l’imagination et de la forme fictionnelle. Ensuite, elle identifie quatre gestes esthétiques qui rendent la possibilité de la guerre nucléaire imaginable. Enfin, à partir d’une étude de la culture populaire visuelle portant sur la catastrophe nucléaire de 1951 à 2019, elle requalifie la période post-1990 comme moment de production d’un imaginaire dans lequel la guerre nucléaire est absente et les armes potentiellement salutaires, par contraste avec les quatre décennies précédentes. Elle s’appuie sur des matériaux empiriques inédits : une campagne d’entretiens auprès de ceux qui perpétuent, luttent contre, filment ou éduquent au sujet de la guerre nucléaire, en France, au Royaume-Uni et aux États-Unis ainsi qu’un sondage de grande ampleur de la population des États européens dotés d’armes nucléaires ou hébergeant des armes nucléaires américaines.

Quels sont les effets des interventions armées menées au nom de la « guerre contre le terrorisme » ? Fondé sur des études de cas localisées, en Afghanistan, au Mali et au Tchad, l’article invite à repenser les présupposés de l’interventionnisme et montre pourquoi la « guerre contre le terrorisme » ne peut être « gagnée » au sens classique du terme et comment elle contribue à perpétuer les conflits et à miner leur résolution. Si chaque configuration est singulière, on retrouve dans ces trois pays des processus similaires de perpétuation des conflits et de co-production de la violence armée par un ensemble d’acteurs internationaux et locaux.
Ce que la « guerre au terrorisme » fait à la justice

Published: March 2022

En matière de droit pénal et de droit de la procédure pénale, ces vingt dernières années ont été marquées par deux mutations majeures : le rapprochement du droit pénal et du droit des conflit armés d’une part et la prépondérance des logiques de prévention et d’anticipation d’autre part. La guerre au terrorisme a contribué à remettre en cause les fondements mêmes du droit pénal libéral. Que reste-t-il du rôle essentiel d’apaisement des désirs de violence lorsque la justice pénale elle-même participe au cycle de vengeance ?
Entre le licite et l’illicite : mobilités humaines, marchés et militarisation des contrôles dans le monde post-bipolaire
Authors: Peralva Angelina , Telles Vera 
Published: March 2022

La fin du monde bipolaire a ouvert la voie à une intensification sans précédent des mobilités humaines et marchandes. Autant sous forme d’un gouvernement des frontières que d’un gouvernement des villes, des dispositifs similaires de contrôle ont été mis en place. Ils se sont appuyés sur la capacité à cerner des frontières ou des espaces mouvants à sécuriser, et sur une militarisation à outrance des techniques et technologies de sécurisation. La même suspension de la loi et des droits, observable sur le plan de ces dispositifs de contrôle et sécurisation, se retrouve dans le mode opératoire de marchés – financiers, mais aussi économiques ou du travail. Tous transitent avec aisance entre le légal et l’illégal, le licite et l’illicite, sous le regard bienveillant des opérateurs de la loi. Ces questions sont abordées à partir de recherches franco-brésiliennes et du point de vue des transversalités nord-sud.

Published: March 2022

Abstract
Capital intensive industrial assets require highly specialized maintenance activities. Traditional preventive time-based approach, based on OEM maintenance policies, has been gradually evolving towards more sophisticated condition-based maintenance techniques. Further ISO 55000 states that assets exist to provide value to the organization and its stakeholders (BS ISO 55002, 2014). To develop a successful and modern maintenance program, it suggests having a value-based approach when dealing with maintenance decisions, both financial and non-financial constrains needs to be evaluated when decision taken regarding maintenance actions. Higher values can be reaped from an asset when the maintenance intervals are optimized. By optimization it is envisaged that the right number and type of maintenance tasks, at the right intervals, in the right way is performed on the asset to maximize the risk reduction within available budgetary constraints.
The paper presents an overview of an analytics framework for predictive maintenance service boosted by Machine Learning and asset knowledge, applied to turbomachinery assets. Optimization of the maintenance scenario is performed through a risk model that assesses online health status and probability of failure, by detecting functional anomalies or aging phenomena and evaluating their impact on asset serviceability.
Mitigating Early Pile Refusal to Meet Foundation Capacity Requirement for Offshore Platform

Published: March 2022

Abstract
The scope of this paper is to present the issues faced during pile installation for offshore platforms specifically due to early refusal and its implication to the required platform foundation capacities. The scope of the paper will include a discussion on pre-development activities, soil reports, drivability analysis, pile and conductor installation using jack-up rig (JUR) and advantages of drill and drive to mitigate early refusal.
Soil parameters obtained from soil boring during pre-development activity are used by the design consultant as upon relied information in developing the foundation design. Pile termination depth is formulated based on required pile capacity than translate into number of piles and size for both operating and storm condition of the platform. Early refusal means that the pile has not reached the termination depth but has met the refusal criteria. This is normally stated in blowcounts per depth at a given measured depth. Meeting the pile refusal criteria does not mean the pile has met the required foundation capacity as per platform design but it only indicates the pile cannot be driven further using the same hammer size. A larger hammer size maybe required provided that the stresses induced during driving is lesser than the allowable stress. During engineering stage, pile driving pattern can be predicted by performing pile drivability analysis and any sign of pile refusal prior to target penetration depth is reported. The outcome can be different for upper bound and lower bound cases that takes into consideration both continuous and set-up case during driving due to equipment breakdown. Mitigation to avoid pile refusal should be deployed to meet pile target penetration depth in ensuring long-term integrity of the platform.
If unavoidable due to limited piles and hammers selection, early refusal can be mitigated with planned drill and drive. Refusal can also occur if actual site condition differs from expected drivability analysis report. Internal skin friction contributed by the soil in the pile annulus is removed to reduce the resistance during pile driving. It is also critical to understand how JUR operates in terms of pile installation, handling of hammer and clean out activities to fully appreciate the complexities of drill and drive.
Based on two recent JUR-installed light weight structure (LWS) projects which is similar in design at two different locations, this paper will outline the notable difference in soil boring data, drivability analysis, planned and unplanned hard driving and corresponding methods on drill and drive.

Abstract
This paper will discuss the key focus areas in successfully delivering a slim well design as a Proof Of Concept (POC) for marginal fields and well cost optimization.
Well Tall-A is a Near Field Exploration (NFE) well targeting marginal reservoir which utilize the slim well concept; a 2-hole section well with 9-5/8" as the conductor. For a successful well execution, three (3) key focus areas were identified which are successful operation of 9-5/8" Casing While Drilling (CWD) to section TD, sustainability of 9-5/8" casing as conductor for the whole well life cycle and achievement of well objectives.
Tall-A recorded the longest and successful 9-5/8" CWD Level 2 (non-directional) for Asia Pacific with 1168m drilled footage as of year 2020. Lessons learnt from previous PCSB 9-5/8" CWD operation were incorporated for casing bit selection hence a heavy-set casing bit (8 bladed) which has been proven in drilling long hole interval in the Middle East (&gt;1000m) was utilized. Continuous monitoring during execution is essential in ensuring the casing is set at the desired setting depth. Sustainability of the 9-5/8" casing as conductor for the whole well life cycle is critical for a slim well design concept. Several studies and extensive discussions between multiple parties has been incorporated to enable utilization of the 9-5/8" as conductor with required sufficient tension to sustain the exploration well lifecycle. A conductor study was performed which incorporated the Metocean data, rig data and connection Stress Concentration Fatigue (SCF) to qualify the 9-5/8" as conductor. To meet the primary and secondary targets; the 8-1/2" hole needs to be kicked-off early and build up to maximum 44 deg before maintain tangent to final TD at 2752m MDDF. Due to the long open hole (1475m) and well inclination within the avalanche hole cleaning regime (30 to 60 deg), the well is prone to hole cleaning problem and wellbore instability. Hence, it is critical to have good drilling practices and precise mud weight selection to ensure no hole problem encountered. The well was successfully drilled to TD, completed the well testing and P&A.
In summary, well Tall-A successfully maneuvered all challenges to deliver the well safely that resulted in Best In Class (BIC) performance. The slim well design concept has been proven achievable and serve as base design for future marginal wells.
Qualification of Cost Effective Mechanically Lined Pipe Solutions for Reel-Lay Installation

Published: March 2022

Abstract
The use of mechanically lined pipe (MLP) for both flowlines and risers installed by reel-lay is well established, giving significant cost and schedule benefits relative to conventional metallurgically clad pipe. Successful offshore installation of MLP is underpinned by comprehensive qualification testing. Evolving MLP products, including the use of thin liners and adhesively bonded MLP, i.e. GluBi®, continue to improve the competitiveness of this linepipe product. The paper will highlight the key steps for qualification, including new products, the lessons learnt captured during fabrication and installation as well as the benefit of a local spool base for the Asia Pacific region.
Subsea 7 has worked in close collaboration with leading supplier Butting to perform the qualification of MLP. The latter, initially, comprises extensive non-destructive and destructive testing of the linepipe materials including the liner/ weld overlay interface. Subsequently reeling test strings are fabricated using qualified welding solutions. Internal visual inspection and dimensional measurements are carried out using laser metrology to provide a benchmark for comparison post reeling. The test strings are given a simulated reeling procedure using bending and straightening formers, representative of Subsea 7's installation vessels. The internal pressurisation technique, as per standard installation practice for MLP, is applied during the simulated reeling procedure. The need for internal pressurisation is eliminated in the case of adhesively bonded MLP. Post reeling the internal laser metrology inspection procedure is repeated to confirm the integrity of the liner and to check for the presence of any evidence of liner wrinkling or damage. Subsequently, for riser applications, full-scale fatigue testing is performed using the high- frequency resonance bending procedure with a focus on the integrity of the junction between liner and weld overlay or, as commonly termed, the triple point.
Additionally, finite element analysis (FEA) is often performed to further validate the satisfactory reeling performance of the MLP. All the qualification activities are carried out and verified in alignment with DNV-RP-A203 Technology Qualification (Ref.1)
To date Subsea 7 has installed several hundreds of kilometers of MLP flowlines and risers, with pipe NPS in the range 7" to 14" and including 316L, Alloy 825 and Alloy 625 liners. This thorough qualification process and experience combined with the successful set up of a regional spool base provides a robust and cost-effective alternative to the conventional metallurgically clad pipe.

Published: March 2022

Abstract
The early detection of a stuck pipe event is crucial as it is one of the major incidents resulting in nonproductive time. An ordinary supervised machine learning approach has been adopted to achieve the detection of stuck pipe in some previous studies. However, for early detection before stuck occurs with this approach, there are challenging issues such as limited stuck pipe data, various causes of stuck, and the lack of a prior exact "stuck sign" which should be a label in the training dataset.
In this study, the surface drilling data is first collected from multiple agencies to enhance the training dataset. Subsequently, a supervised machine learning algorithm with ordinary binary classification methodologies, such as support vector machines and neural networks is adopted. The supervised machine learning approach presents good performance for stuck pipe event detection. However, it detects "stuck has already occurred", and it cannot effectively predict the stuck pipe because there is no exact sign for stuck pipe which is mandatory as label for training data.
This study also adopts an unsupervised machine learning algorithm which employs architectures that include an autoencoder with long short-term memory, as well as a multiple prediction model to improve the expressiveness. The unsupervised machine learning process typically involves learning the features of normal activities, whereby the created model can represent only these activities. When stuck occurs or will occur, as such data are not represented by the created model, it should be detected.
The performance of the early stuck pipe event detection using supervised and unsupervised machine learning approaches is analyzed, and the results demonstrate that the unsupervised machine learning approach presents a better early stuck pipe detection capability. The proposed machine learning algorithm will be further improved in the future and the prediction result will be validated through actual operation.
An Electrifying Integrated Solution Towards a Safe and Environmentally Sound Well Abandonment in Urban Setting

Published: March 2022

Abstract
In the Netherlands, a large number of onshore wells are near urban areas or close to forests where environmental emission and noise reduction are important to consider. With more than 23 different well site locations to be abandoned, a significant amount of collaboration is required to ensure there is minimal interruption and impact to the local community and the environment.
To achieve this, the operator together with Baker Hughes as the project management lead, formulated a unique, low-impact solution with fully electrified equipment that mostly uses grid power. Alongside other service partners, the majority of the onsite equipment are electrically driven, such as the rigless well abandonment unit, cement pumps, ancillary equipment, and the slickline unit. A noise dampener and decibel readers were put in place to minimize and track sound emissions.
Such collaboration and integration with all providers were carefully identified and mitigated through a series of non-technical risks (NTRs) to ensure compliance with local regulations. Extra steps were taken to ensure that smell and noise remain unnoticed by the surrounding environment. Frequent communications are sent to the public by the operator to keep everyone informed prior to any mobilization.
After a one-year campaign, there have been zero LTI, zero accidents, zero non-compliance incidents and above all, safe and secured end-of-life oil wells in an urban setting with many more to follow suit.
This paper will provide insight into the integrated operations of a well abandonment project in a unique urban setting and the challenges to successfully abandon wells of varying complexity. This project is to be accomplished in compliance with the local mining and environmental regulations with no remaining liabilities, all while limiting total project costs. The supply chain stepped up by providing a cost-effective solution through multi-party collaboration, multi-skilling, technology innovation, and logistical solutions. The project planning, start-up phase, and an overview of the first year of operations will be presented.
Laboratory Investigation of Hybrid Nano-Assisted-Polymer Method for EOR Applications in Carbonate Reservoirs

Published: March 2022

Abstract
Currently, there has been a surge in evaluating the effectiveness of various hybrid enhanced oil recovery (EOR) methods as they combine the benefits of standalone processes. This study focuses on laboratory investigation to evaluate synergy between polymer and nanoparticles (NP), as their combination can simultaneously alter capillary and viscous forces.
N-vinyl-pyrrolidone-based partially hydrolyzed polyacrylamide and silica oxide nanoparticles are used in this study. The standalone polymer, nanofluid (NF), and combined polymer-nanofluid solutions are prepared in different salinities (1200-40,000 ppm). The zeta potential of solutions is measured to determine the stability of NF at various salinities. Contact angle measurements are performed to determine the optimum concentration of NP. A series of rheological experiments are accomplished at different nanoparticle concentrations (0.05, 0.1, 0.15 wt%), temperatures (25-80 °C), and polymer concentrations (500 to 3000 ppm). Additionally, a long-term stability test was conducted over thirty days at 80°C on nano-assisted-polymer fluid over a long period.
Zeta potential results proved that the stability of nanofluids decreases with an increase in solution salinity. However, the addition of polymer has a positive impact on the stability of NF and is stable up to 40 000 ppm salinity. The nanoparticles have shown potential in altering the wettability of the rock toward the intermediate wet conditions. A maximum deviation of 55° in contact angle is observed for a 0.1 wt% NP solution and is selected as optimum concentration. Rheology studies illustrate that the addition of NP increases the viscosity of the polymer solution by 25%. All nano-assisted-polymer solutions tested in this study showed shear thinning behavior. Long-term thermal stability of nano-assisted-polymer solution indicates that the solution achieves equilibrium after 5 days and maintains target viscosity of 4 cP.
The addition of polymer has positively impacted the salinity tolerance of nanoparticles. Additionally, nanoparticles improved the viscosity of the polymer solution. This study will open new doors for the hybrid EOR method.
