Le rapport de travail en France au XIX e siècle : un rapport marchand ?
Authors: Lemercier Claire 
Published: August 2021

Les renouvellements de l’historiographie ont révisé une vision du travail au xix e siècle qui était dominée par les modèles du paternalisme, de la discipline usinière et de la liberté de contrat sans limite. Ils décrivent des rapports de travail plus précaires mais aussi plus négociés, notamment dans le cadre des chaînes de sous-traitance complexes de la fabrique collective et de la proto-industrie. Les conseils de prud’hommes étaient en particulier un lieu de délibération sur des règles qui pouvaient dans une certaine mesure redresser le rapport de forces en faveur des ouvrier·ère·s. Ces conseils produisaient un « droit des ouvriers », bien distinct de celui des marchands, même si les rapports entre ouvrier·ère·s et patron·ne·s ressemblaient à des rapports marchands. Les conseils de prud’hommes étaient cependant loin d’être accessibles à tou·te·s les travailleur·euse·s manuel·le·s ; beaucoup ne pouvaient pas participer à l’élaboration de ce droit ni bénéficier de son application.
Que peut-on encore espérer de la méthode expérimentale ? Étude comparée en Sciences de Gestion et en Médecine
Authors: Helfrich Vincent , Weber Jean-Christophe 
Published: August 2021

Cet article propose de clarifier et de dépasser l’irréductible variabilité qui contrarie toute tentative de qualification des pratiques expérimentales au sein d’une discipline ou à travers les disciplines. Pour ce faire, nous mobilisons la notion philosophique d’air de famille, au sens de Wittgenstein, qui permet de catégoriser des objets conceptuels sous la contrainte de leurs ressemblances et dissemblances. Notre analyse est basée sur une étude comparative entre la gestion et la médecine. Cette dernière permet de qualifier à la fois un air de famille « interne » aux pratiques expérimentales propres à chaque discipline (gestion et médecine) et un air de famille « externe » entre ces deux disciplines. Cette analyse insistera notamment sur les cas archétypiques des perspectives expérimentales de la recherche-intervention en gestion et de la clinique médicale.
Coronavírus é como: relações de sentido a partir de metáforas por símile
Authors: Pimentel Rocha Jean Michel , Curti-Contessoto Beatriz 
Published: August 2021

Neste artigo, debruçamo-nos sobre metáforas por símile a fim de analisá-las no contexto da pandemia de covid-19, considerando as relações de sentido em jogo, as quais abarcam domínios conceituais, aspectos socioculturais, bem como funções pragmáticas e discursivas que emergem das situações examinadas. Para tanto, assumimos um quadro teórico que concebe a metáfora como um fenômeno multifacetado, permeando distintos níveis linguísticos. Ademais, adotamos um método baseado na web como corpus para identificação das metáforas, por meio dos gatilhos coronavírus é como, covid-19 é como, coronavírus é que nem e covid-19 é que nem. À luz de nossos achados, de modo geral, podemos afirmar que, mesmo que os enunciadores lancem mão de domínios metafóricos similares, eles o fazem a partir de distintas posições e intenções discursivo-argumentativas, o que pode resultar, por exemplo, em avaliações positivas ou negativas acerca dos efeitos da pandemia.

Simultaneous estimation as an alternative to young eucalyptus aboveground biomass modeling in ecophysiological experiments

Published: August 2021

Accurate forest biomass estimates require the selection of appropriate models of individual trees. Thus, two properties are required in tree biomass modeling: (1) additivity of biomass components and (2) estimator efficiency. This study aimed to develop a system of equations to estimate young eucalyptus aboveground biomass and guarantee additivity and estimator efficiency. Aboveground eucalyptus biomass models were calibrated using four methods: generalized least squares (GLS), weighted least squares (WLS), seemingly unrelated regression (SUR), and weighted seemingly unrelated regression (WSUR). The approaches were compared with regard to performance, additivity, and estimator efficiency. The methods did not differ with regard to the mean biomass estimation; therefore, their performance was similar. The GLS and WLS approaches did not satisfy the additivity principle, as the sum of the biomass components was not equal to total biomass. However, this was not observed with the SUR and WSUR approaches. With regard to estimator efficiency, the WSUR approach resulted in narrow confidence intervals and an efficiency gain of over 20%. The WSUR approach should be used in forest biomass modeling as it resulted in effective estimators while ensuring equation additivity, thus providing an easy and accurate alternative to estimate the initial biomass of eucalyptus stands in ecophysiological models.

Published: August 2021

AbstractInjection wells experience extremes of pressure and temperature as well as expansion and contraction during their normal operating cycles. This can cause numerous well integrity issues related to corrosion, leakage, degradation of barrier elements, operational practices that all put the health of the well at risk and require appropriate management.This paper will describe a case of a North Sea injection well that over time had developed sustained casing pressure (SCP) in the B-annulus. As a critical well in the development it was necessary to understand the origin and nature of the SCP as this would set further operational plans for the well helping to decide whether the well could continue to be operated safely, would require an intervention, or potentially will be abandoned. A leak investigation was needed to try to determine the source of the pressure, the type of fluid causing the pressure, the fluid path, and whether there was an injection out-of-zone as a result.To address all of the set objectives Distributed Fibre Optic (DFO) system was selected as a technology of choice. DFO provides an advantage over traditional leak detection methods through the ability to simultaneously monitor entire length of the well recording both acoustic and temperature profiles. Distributed Acoustic Sensing (DAS) was used to record acoustic signature of the well helping to determine the leak origin and likely pathway, while Distributed Temperature Sensing (DTS) was used to record well outflow profile and advise on possibility of out-of-zone injection. Use of pattern recognition techniques allowed to extract leak signature from background noise and other acoustic signals helping to pinpoint leak location.As a result of the application of DFO technology coupled with appropriate processing techniques way ahead for the well was identified providing an operator with a confident answer and saving on further intervention costs.

AbstractExploration in the Guyana-Suriname Basin has been a decades-long endeavor, including technical challenges and a lengthy history of drilling with no offshore success prior to the Liza discovery. The 1929 New Nickerie well was the first onshore well in Suriname, and was followed by 30 years of dry holes before the heavy-oil Tambaredjo field was discovered in the 1960s. In the 1990s, nearly 40 years after the Tambaredjo discovery, ExxonMobil utilized the 1970s-vintage, poor-to moderate-quality, 2D seismic and gravity data available to create a series of hand-drawn, level-of-maturity (LOM) source and environments-of-deposition (EOD) maps over the basin to move their exploration efforts forward. This work established the genetic fundamentals necessary for understanding the hydrocarbon system and led to negotiation for and capture of the Stabroek Block in 1999.The Liza-1 success in 2015 spurred extensive activity in the Basin by ExxonMobil and the Stabroek Block co-venturers, Hess Guyana Exploration Limited and CNOOC Petroleum Guyana Limited (Austin et al. 2021). The collection of extensive state-of-the art seismic data has been leveraged to enable successful exploration of multiple play types across the Guyana-Suriname Basin. Further data collection, including over 2 km of conventional core and additional seismic data acquisition and processing, has enabled ExxonMobil to adopt interpretation techniques that are applied across the entire basin to characterize and understand the subsurface better.From initial hand-drawn maps to the use of advanced technology today, ExxonMobil's work in the Guyana-Suriname Basin has relied on integration of geologic and geophysical understanding as well as the ability to leverage new technology to continue a successful exploration program with 8 billion barrels discovered to date.
Principles for Selection of the Quality, Health, Safety and Environmental Digital Solution
Authors: Efendi Riad , Cabassa Marc , Cagnart Bruno 
Published: August 2021

Abstract
A digital solution for the Quality, Health, Safety and Environmental (QHSE) management system has lately become almost a must for any progressive company, especially the one that strives to take on, pass and maintain third-party certifications (such as ISO 9001, 14001 and 45001).
However, its selection may be a complicated process balancing interests of field workers, executives, procurement, IT, safety/environmental/risk managers and training personnel.
The process of selection of the QHSE digital solution starts with defining the scope of the project and its sponsors, stakeholders, resources and budget (most likely estimated, at initial stage).
The next step is building of a list of requirements of a desired solution based on feedback from business. It will be followed by research of available solutions on the market and/or in-house capabilities to develop one.
Three to five vendors with solutions best conforming to the defined requirements will be requested to do presentations of their capabilities, followed by proof-of-concept for 2-3 top candidates, leading to a selection of a winner.
Despite the process described here being very straightforward, there may be pitfalls caused by complex interplay of interests of different disciplines and divisions within the company.
The most important conclusions addressing these pitfalls are:
It is unlikely that you will find one vendor, whose solution will become the best fit for all disciplines comprised by your management system (quality, occupational health, safety and environmental). An early decision needs to be made (most likely at the executive level) if you would go with a One Solution (Best-of-Suite) or different specialized software (Best-of-Breed) approaches. You need to get a very good idea of various QHSE-related software currently being used in your company at local or division levels. If the decision is made to switch to a new comprehensive digital solution on a global level, you will need to get a buy-in from local/division users before making this switch. Finally, you need to ensure that all stakeholders and interested parties are involved in (or at least informed of) the selection process and agree on its scope.

Abstract
The industries using floating facilities such as FPSO and offshore wind turbine are increasing. Since these vessels have been fixed and operated in the installed area for a long period of time, they cannot be regularly docked, inspected and repaired as opposed to normal ship case, and limited to the inspection of the hull outer plates from under the water and the inspection of inside the tanks are conducted once every five years. These inspections involving visual inspections and thickness measurements at representative points, only examine the current state, and don’t evaluate quantitatively the future potential (remaining life) over the subsequent long operation period. To predict residual life in order to maintain the integrity of these structures, digital twin technology is proposed to realize this demand. This paper shows the method to develop digital twin assessment which solve the insufficiency of conventional monitoring and simulation method in order to utilize for risk-based inspection (RBI) and condition-based maintenance (CBM) to the operators.
Drilling with Glass and Air: Using Hollow Glass Spheres to Address a Wide Ranging Drilling Challenge in a Safe, Efficient and Cost-Effective Manner

Published: August 2021

Abstract
A major development with multiple rigs delivering extensive multi-laterals encountered a pervasive mud-window issue within the reservoir. The resulting severe mud losses, extensive NPT and formation-damage was also deteriorating with time due to depletion. Conventional approaches to stem losses had failed and adoption of an energized mud-system with acceptable Effective Circulating Density (ECD) was not considered cost effective, pragmatic nor safe. Instead a novel application using Hollow-Glass-Spheres (HGS) was trialled, that demonstrated an effective and highly successful outcome.
With 10 rigs drilling 60-70 wells per-year, each with 5,500 to 6,750m in the reservoir, quick resolution of the issue was required. For these reasons the Team at bp Russia looked carefully at alternatives that might fit the mud-window, but that offered a realistic approach for the environment and conditions in Eastern Siberia. The Team identified HGS as an approach to lighten the mud, often used for cementing ECD, application for drilling has been limited. For this approach we required an option with broad capabilities that could be scaled-up and exported to other development areas where such issues existed.
This paper will report on the planning, delivery, and execution of a pilot on the Sb. field at TYNGD, in Eastern Siberia. Initially deployed on three wells, including multi-laterals, the paper will walk through the engineering considerations, during the planning and execution phases. Reporting comprehensively on the data gathered and the many lessons learned during the incremental and stepwise deployment. Data will be provided that demonstrated loss-free drilling was achieved where this had not occurred before, with a dramatic reduction in NPT, FLA needs and costs. The paper will also report on the post drilling productivity and comparison with offset wells drilled with conventional mud systems and suffering severe losses. The results of this pilot have beaten all expectations, there have been many insights and the Team are now looking to set a timetable to scale-up across the NOJV. Much has been learned, waste HGS material has been demonstrated to be an effective FLA pill in other sections of the well and centralisation of mud process may offer additional cost savings and improvements. Further efficiencies are expected to be achieved and potential across the Company portfolio could be a major game changer.
HGS for cementing is well documented, application for drilling fluids has been less reported and almost exclusively applied to one-off sections/wells. The TYNGD application is novel as this is a major new development with 10 drilling rigs. Application is on multi-laterals and prior offset wells are available for direct comparison. The results of the approach demonstrate a new way of performing well construction in an effective manner for major Field Developments where losses are prevalent.
Electrically Heated Trace Flowline on Ærfugl Project - A journey from Product Qualification to Offshore Campaign

Published: August 2021

AbstractThe Ærfugl field is close to the existing Skarv development located in Norwegian Sea, making it a tie-back opportunity. The hydrate management and operational savings were major drivers for the subsea system design requiring the use of an electrically heated trace flowline (EHTF).The scope of this paper is to present how the EHTF technology has been further developed, qualified and industrialized during the execution of the Ærfugl project. It will also illustrate how a unique collaborative model between an Operator, an SPS Contractor and an EPCI Contractor contributed to the delivery of the first heated Pipe in Pipe system on a sizable project.Starting from a conceptual technology selection to the project delivery, numerous qualifications were performed to validate the EHTFsystem design and ease its industrialization. The development of a new technology starts from the component design through system qualification up to the installation phase. It is of prime importance that all the different phases of the system life cycle are equally considered, as being interdependent. By using this holistic design approach right from the start of the qualification phase, the final product eventually meets all the requirements, from the component specification to the system performance.The collaborative model in place on the Ærfugl project allowed the efficient integration of the Operator at each different step of the design, qualification and industrialization process resulting in delivery schedule savings when compared to a conventional project delivery approach. Several important development activities took place during the Ærfugl project and the holistic design approach backed by robust system engineering processes enabled a smooth and efficient workflow supporting the onshore fabrication and offshore installation readiness activities.Several fabrication challenges were overcome during the project to safely deliver the EHTF solution with a continuous focus on quality and this paper will also cover the most relevant ones.Following the Ærfugl project execution, the EHTF technology, supported by a unique collaborative model with the operator, is now fully qualified, and deployed offshore based on robust and reliable manufacturing and installation methods.

Published: August 2021

SummaryOffshore fields present a growing need to guarantee safety and productivity while minimizing operational costs and increasing remote assistance. Brownfields are more exposed to risks due to the presence of aged assets requiring in depth inspections to assess potential life extensions. This challenge was tackled with a comprehensive approach to asset integrity management based on the enhanced use of digital solutions to enable new health care services on offshore assets, like CALM Buoys.In line with the recent Oil & Gas industry trends, new digital technologies have been recently developed and deployed on board our fleet of CALM (Catenary Anchor Leg Mooring) Buoys, such as the 3C Telemetry system, Inspection Tablets, the IDEA Web Portal and the Marine Drone. All these new digital solutions will be presented in the proposed paper concerning their technical capabilities and the overall integrity performance improvements achieved with their enhanced use on offshore assets.The 3C Telemetry system converts and upgrades CALM Buoys into smart, internet-friendly offloading terminals, connecting the system to Cloud services and ensuring secured data transmission, treatment, storage, and privacy, while delivering reliable accurate information to operators anywhere in the world. Inspection tablets are used to optimize health check campaigns on Buoys with a real-time and remote back office engineering support. These systems can also be connected to the IDEA (Imodco Digital Experience Access) Web Portal to allow online data visualization and analysis of the mooring systems performance."The Marine Drone is an unmanned survey vehicle to perform diverless UWILD (Underwater Inspection in Lieu of Dry-docking). The system can perform in depth visual inspections with its ROV (Remotely Operated Vehicle) and high-resolution subsea layout mapping of CALM buoys’ structures with its 3D bathymetry system, all providing high quality digital data post processed by advanced analytical tools for integrity analysis and preventive maintenance planning" (Castro, R., et al. 2020).Data management has become the most valuable asset for companies seeking to have a better understanding and to continuously improve operations. This paper will demonstrate how Buoys and passive (process wise) equipment, like Turrets, can be operated in new ways: 1. Connected Asset (IoT): 3C Telemetry, Tablets, and the Marine Drone. 2. Platform to share/connect data to algorithms/users: IDEA System. 3. New operating business models enabled by health care approach.
Characterization of Productive Zones with Data from Advanced Mass Spectrometry of HPHT Well

Published: August 2021

Abstract
The construction of the A-2 well is considered challenging because it is a horizontal offshore HPHT well in shallow water. In fact, the well had a programmed target to reach the carbonatic rocks of the Upper Jurassic Kimmerdgian age, a light oil producing reservoir of complex type and low porosity, consequently, to select the best intervals with oil presence and define the location of water–oil contact was vital to avoid unnecessary deepening saving additional costs.
Being the data interpretation of the geochemical profile in the JSK zone of main importance for reservoir characterization, allowing to determine prospective intervals in a timely manner as a key task. The information from the lithological description was integrated into the geochemical profiles, where intervals of interest are related to hydrocarbon impregnations, fluorescence and visual porosity of each one of the samples.
