Abandoned Well Monitoring System with Wet Christmas Tree
Authors: Eduardo Gonzales Panta Pedro , Campos Furtado Rafaela , Roberto Moreira José 
Published: October 2019

Abstract
This paper approaches the challenges of temporarily abandoned well monitoring with wet christmas tree (WCT), analyzes the regulatory requirements, the Brazilian scenario and proposes a new methodology system to checking the two Well Safety Barriers (WSB) integrity as required by the ANP (Petroleum National Agency, the regulatory institution in Brazil) resolution nO46/2016. So, the system is compared with other monitoring alternatives, even economically, namely: using rigs or plugging and abandonment. A system is presented that allow the monitoring by means of WCT chamber pressurization or depressurization, hydrocarbons detection, leak measuring by control valves, measuring the WTC chambers pressure, collecting the probable hydrocarbons in a safety way and, and if required, actuating some WTC valves. The control valves and WTC chambers are accessed by the Vertical Connection Module (VCM) mandrel where a modified abandonment cap will be installed with a Control Module on the top. An isolation valve is installed in the Control Module, as a WSB redundancy. The monitoring system avoids the use of expensive intervention rigs and allow the indefinite postponement of plugging and abandonment, entailing sensible economic gains. In addition, the control module installation is made along with the abandonment cap, therefore, no additional cost is required. Another main issue is that the control module monitoring not entails significative impact in the time of well inspection routine. Besides fulfills the legal requirement, the monitoring system provides safety in operations and economic gains when compared to other alternatives. The proposed system patent has been deposited in Brazil. The economy and safety offered by the monitoring system doesn´t have similarities to the existing methodologies in the international market. However, it will be necessary a test prototype to develop.
Depth Imaging of Complex Geological Structures using the RTM Technique in Order to Reduce Exploration Costs
Authors: Xavier Mitchel Wagner 
Published: October 2019

Abstract
This work aims to perform a comparison of depth imaging results using values not commonly used for source and receiver intervals to prove that it is possible to obtain good results, in terms of the quality of seismic sections, with less data, which can significantly reduce petroleum exploration costs. Bidimensional acoustic modeling with a finite difference scheme was applied to a slice of the 3D SEG/EAGE Overthrust model to generate the synthetic seismograms. These seismograms were generated comparing 25 m for shot and receiver intervals, which is a common interval for a seismic acquisition process, with 200 m for shot and receiver intervals, which is not a common value. A reverse time migration (RTM) technique was applied to perform the depth migration of the generated pre-stack seismic data, and the migrated shots were stacked to create the seismic section. In addition, suggestions related to seismic illumination studies and visibility analyses are discussed to improve the results and to contribute to exploration and production (E&P) cost reduction. In these cases, the SEG/EAGE Salt Dome model and the Sigsbee model from the SMAART JV project were used to illustrate the discussion.

Abstract
Libra Area has presented gas/oil ratio (GOR) and CO2 content higher than the typically found in other Pre-Salt fields. These characteristics can significantly increase the size and complexity of the gas processing plant (GPP), especially in gas export scenarios. More efficient gas treatment technologies and with the ability to handle high CO2 levels need to be developed to reduce footprint and weight, improving oil plant capacity. This paper presents two membrane technologies selected for evaluation: Carbon Molecular Sieve (CMS), a partnership with Shell focused on CO2 removal, and All Membrane Solution (AMSTM), a commercial Air Liquide solution that can optimize the GPP layout by replacing conventional processes used for contaminants removal. AMS aims to remove, not only CO2, but also other contaminants such as H2S, H2O, and heavy hydrocarbons. Both technologies promise to lower the CAPEX and OPEX while increasing the oil production capacity, leading to more economically attractive projects. The demonstrations will be carried out at Atalaia Experimental Nucleus (NEAT), which is a Petrobras’ center for gas technology assessment, located in Aracaju city, Brazil. Pilot-scale skids operating under Libra typical gas conditions will be used for technology assessment. CMS and AMS will be tested sequentially, the former expected to start in the second half of 2019 and the latter in the first half of 2020. For CMS technology, further tests on an industrial-scale prototype will still be needed afterwards, whereas for AMS, due to its higher technology readiness level (TRL), it is expected that it can be implemented just after the demonstration.

Abstract
An innovative Oil Loading Terminal (OLT) system was recently developed to attend FPSOs (Floating, Production, Storage and Offloading) units up to 250.000 barrels/ day of oil production and operating in deep waters. This OLT allows offloading operations from the FPSOs onto Very Large Crude Carriers (VLCC) shuttle tankers moored in a Single Point Mooring Buoy type usually called CALM Buoy. The heart of this OLT concept is a tether anchored subsurface buoy - named BSL (Buoy for Supporting Lines) - application to support the submerged Oil Offloading Lines OOL segments between the FPSO and CALM Buoy. The BSL presence de-couples the motions of the two floating bodies. As a result, the OOLs loads and fatigue efforts also decrease on all connections. The fact is the submerged BSL will decrease the wave's impact on the design. It is important to recognize that all components are field proven and installable as described in [4]. The scope of this paper is to evaluate some different arrangement of the OLT submerged components to assess the level of influence of each one.
This work will perform a parametric assessment of the main geometric and inertial characteristics of each component seeking consequences on the static and dynamic tensions in hot spots and the fatigue life on the main components. The first aspect to watch is related to the relative and total horizontal distances between the FPSO, BSL and CALM Buoy. The other is the depth of the BSL, followed by the floater length in both branches of the flexible lines. Geometries were tested in Santos basin, Brazil (2200m water depth). For each case an economic quantification is performed, since the best economic result may not coincide with the best tension and fatigue life.
The proposed OLT should allow the employment of conventional tankers, either Suezmaxes or VLCCs, connected onto the FPSO via a CB and a BSL plus OOLs, by placing the largest fraction of the OOLs weight supported by the FPSO and BSL. The sections of the OOLs between the BSL and the FPSO can be of either steel or flexible; or even a combination of both.
The use of BSL conception for the Brazilian offshore pre-salt area is in fact a reliable, safe and robust system when compared with the FPSO tandem offloading or the complementary Ship-to-Ship oil transfers.

Abstract
Tight gas reservoir has potential to provide a significant contribution to meet the global energy demand. Unconventional resource plays and in particular tight gas reservoir are generally characterized by lower geologic risk but higher commercial risk. For that reason, a precise understanding of the potential range can lead to the commercial success; this weighs on the economic evaluation process.
The cutting-edge method "Technical Datamining" (DM), use artificial intelligence, statists, and algorithm of learning machines to accomplish new knowledge of clustering and predictive types. Neural networks-DM are computational models that have been used in different research fields with outstanding results. Thus, models of temporal series are pursued to develop to achieve reliable estimations of the main economic indexes: NPV, IRR, Payout and investment performance in the high-risk Oil & Gas portfolios, in particular economic evaluation of unconventional/Tight Gas resources, which is our concern. Neural networks learn from experience and errors: when more wells of the investment's portfolios are added, the experience will improve.
The process of knowledge improvement begins with the extraction, transformation and loading data to the collection of the resultant model and its analysis. This involves an exhaustive work with the exploration and evaluation with the behavior of independent variables (Capex, Opex, Reserves, Gas Price and Time), the outliers, the normalization, variability and the distributions. Furthermore, it is vital to maintain a complex and extensive training of the neural network model with different parameters and iterations, using the previous experience's expert. Our study has 4 years and a monthly seasonality for processing the data in the search to optimize decision making.
The model application will be developed in the sectoral block of the Lajas Formation of the Neuquén Basin, with six wells in production, the GOIS value above 3000 MMm3 and the current recover factor estimated in 19 %. In addition to this, are expected the incorporation of new wells to the block to increase the recovery factor above 35 % and thus improve the return on investment (NPV / Investment). Finally, the construction of neural network model will provide predictive values more precisely through a time series using 80 % focusing on tasks for training and 20% for testing, with minor errors of 5 %.

Background: Antiretroviral therapy (ART) started between 7 and 12 weeks of age improves neurodevelopmental outcomes in HIV-infected (HIV+) infants, but the impact of even earlier initiation is not yet described.Objective: We assessed the early neurodevelopment of HIV+ infants who started ART within 21 days of life. Methods: Participants were enrolled from the public sector birth HIV-diagnosis program. Inclusion criteria included: birth weight 2000g, infant commencing ART 6 weeks and no infant Cytomegalovirus disease. ART included Zidovudine/Lamivudine/Nevirapine for the first 2 weeks, the latter then replaced by Lopinavir/Ritonavir. Once body weight 3kg and gestational age 44 weeks, Abacavir replaced Zidovudine. The Griffiths Mental Development Scales (GMDS) were administered at 10-12 months.Results: Of 29 infants assessed, 23 (79%) were girls. Mean birth weight was 3002 ± 501g. Twenty-four mothers (83%) received ART during pregnancy. Seven (24%) infants were diagnosed HIV+ within 48 hours of birth. Median [IQR] viral load (VL) at diagnosis was 3904 [259;16922] copies/ml, age starting ART was 6.0 [3;10] days and age at VL suppression was 19.1 [15; 36] weeks. At the GMDS assessment nine (31%) participants had detectable VL and 26 (90%) had WHO clinical stage I disease. GMDS was performed at a mean age of 11.5±0.8 months. Mean quotients were within the average range: Global Griffiths score was 103.6±10.9 and mean quotients on the subscales ranged from lowest 95.9±13.4 for Locomotor to highest 112.8±11.3 for Hearing-and-language.Conclusion: Preliminary findings in this small group suggest that early neurodevelopmental scores are within the normal range in infants with perinatal HIV-infection who started ART at a median of 6 days.
Improving Value-Based Care Education in a Fellowship by Incorporating ACGME Competencies
Authors: Zanotti Kristine , Somasegar Sahana , Hooper Monica Webb , Hopp Elizabeth 
Published: October 2019

ABSTRACT

Background
Most value-based care educational interventions teach knowledge of cost but fail to recognize the interrelatedness of the Accreditation Council for Graduate Medical Education (ACGME) competencies of medical knowledge, patient care, practice-based learning and improvement, and systems-based practice.

Objective
We analyzed the impact on clinical decision-making of an educational curriculum that incorporated the spectrum of ACGME competencies.

Methods
Five didactic sessions for a gynecologic oncology fellowship were modified to incorporate cost- and value-based care considerations for each clinical topic addressed. After discussion, the group of fellows identified 1 high-value and 5 low-value practices to target for improvement. The fellows then undertook a chart audit of clinical decisions occurring for patients seen in the outpatient clinics. The frequency of low- and high-value practices was compared before and after the educational intervention.

Results
A total of 126 patients with a cervical cancer diagnosis were seen by participants in the outpatient setting during the entire observation period. After the intervention, the occurrence of 3 identified low-value practices was reduced by 13% to 33%, demonstrating modest effect sizes (effect size φ = 0.2–0.3). One high-value practice (smoking cessation counseling) increased 100% after a fellow-initiated quality improvement project was undertaken. Two low-value practices, including routine surveillance imaging, remained unchanged.

Conclusions
Overlaying value-based concepts in didactic conference teaching resulted in measurable changes in decision-making behavior. Engaging learners in a subsequent, focused quality practice review served as a vital part of their educational experience and allowed us to assess learner competency in its practical application.

ABSTRACT

Background
Graduates of emergency medicine residency programs can seek certification from the American Board of Emergency Medicine (ABEM), yet the costs and perceived value by residents is not clear.

Objective
This report sought to better define the value of board certification by asking physicians taking the ABEM Oral Certification Examination (OCE) to describe its costs (eg, time, money) and perceived benefits.

Methods
A descriptive, cross-sectional, voluntary, anonymous survey was administered to physicians taking the 2018 spring and fall ABEM OCEs. Response frequencies were used to report response rates.

Results
There were 2016 physicians who participated in the 2018 OCEs, of whom 1565 (78%) completed a survey. With respect to preparation, 38% (599 of 1565 responses) spent more than 30 hours preparing for the examination. Regarding the expense of preparing for the examination, 21% (328) spent nothing, 50% (776) spent less than $1,000, and 2% (38) spent more than $3,000. Most physicians (80%, 1254) reported a learning benefit to preparing for and taking the OCE. There were 49% (765) of respondents who reported that preparing for the examination reinforced their knowledge of emergency medicine; 20% (311) reported no learning benefit. Most physicians (92%, 1442) reported that ABEM certification provided a career benefit, the most common of which was more career opportunities (69%, 1076).

Conclusions
Initial certification requires a considerable investment of time and money. Physicians seeking initial ABEM certification found both learning and professional benefits, with the most frequently reported being reinforcement of medical knowledge and more career opportunities.
Detection of Residents With Progress Issues Using a Keyword–Specific Algorithm
Authors: Tremblay Gaby , Carmichael Pierre-Hugues , Maziade Jean , Grégoire Mireille 
Published: October 2019

ABSTRACT

Background
The literature suggests that specific keywords included in summative rotation assessments might be an early indicator of abnormal progress or failure.

Objective
This study aims to determine the possible relationship between specific keywords on in-training evaluation reports (ITERs) and subsequent abnormal progress or failure. The goal is to create a functional algorithm to identify residents at risk of failure.

Methods
A database of all ITERs from all residents training in accredited programs at Université Laval between 2001 and 2013 was created. An instructional designer reviewed all ITERs and proposed terms associated with reinforcing and underperformance feedback. An algorithm based on these keywords was constructed by recursive partitioning using classification and regression tree methods. The developed algorithm was tuned to achieve 100% sensitivity while maximizing specificity.

Results
There were 41 618 ITERs for 3292 registered residents. Residents with failure to progress were detected for family medicine (6%, 67 of 1129) and 36 other specialties (4%, 78 of 2163), while the positive predictive values were 23.3% and 23.4%, respectively. The low positive predictive value may be a reflection of residents improving their performance after receiving feedback or a reluctance by supervisors to ascribe a “fail” or “in difficulty” score on the ITERs.

Conclusions
Classification and regression trees may be helpful to identify pertinent keywords and create an algorithm, which may be implemented in an electronic assessment system to detect future residents at risk of poor performance.
Contemporary Indonesian Fashion
Authors: Lopez y Royo Alessandra 
Published: October 2019

Indonesian fashion has undergone a period of rapid growth over the last three decades. This book explores how through years of social, political, and cultural upheaval, the country’s fashion has moved away from “colonial fashion” and “national dress” to claim its own distinct identity as contemporary fashion in a global world.
With specific reference to women’s wear, Contemporary Indonesian Fashion explores the diversity and complexity of the country’s sartorial offerings, which weave together local textile traditions like batik and ikat-making with contemporary narratives. The book questions concepts of “tradition” and “modernity” in the developing world, taking stock of the elite consumption of luxury brands and the large-scale manufacturing of fast fashion, and introduces us to the rise of new trends such as busana muslim (or “modest wear”), creating a portrait of a vibrant and growing national and, increasingly, international, industry.
Exploring clothing in shopping malls, on the catwalk, in magazines, and online, the book examines how Indonesian fashion is made, presented, and consumed, combining research in Indonesia with analysis and personal reflection. Contemporary Indonesian Fashion ultimately questions the deeply entrenched eurocentrism of “global fashion”, simultaneously interrogating current homogenizing beauty and body image discourses posited as universal, by pointing to absences, silences, and erasures as reflected by contemporary Indonesian fashion— hence the “looking glass” of the title. Aptly illustrated, the book offers a new perspective on a rapidly developing new fashion capital, Jakarta.
The Third Realm of Luxury
Authors: Roberts Joanne , Armitage John 
Published: October 2019

In a world that is obsessed with luxury, critical luxury studies is a rapidly emerging field. This is the first book to explore the interplay between the real and imaginary realms of luxury, considering the most significant developments in the theories and practices of luxurious places and spaces over the last fifty years.
Providing a critical approach to contemporary interpretations of luxury, the book interrogates the distinction between real places and imaginary spaces. Bringing together an interdisciplinary group of leading scholars, it features a range of case studies which take the reader from the Rolls-Royce Ghost Black Badge to expressions of sensuality in the 1970s domestic interior, and global conceptions of fine wine and art.
The Third Realm of Luxury considers the interplay between luxury and space in both the past and the present, examining the abstract conception of excess and exoticism, as well as the real locations of the home, hotel, apartment, and palace. Full of original research, it is a key contribution to the study of consumption, design, fashion, and architecture.
Bond Girls
Authors: Germanà Monica 
Published: October 2019

Since Ursula Andress’s white-bikini debut in Dr No, ‘Bond Girls’ have been simultaneously celebrated as fashion icons and dismissed as ‘eye-candy’. But the visual glamour of the women of James Bond reveals more than the sexual objectification of female beauty. Through the original joint perspectives of body and fashion, this exciting study throws a new, subversive light on Bond Girls. Like Coco Chanel, fashion’s ‘eternal’ mademoiselle, these ‘Girls’ are synonymous with an unconventional and dynamic femininity that does not play by the rules and refuses to sit still; far from being the passive objects of the male gaze, Bond Girls’ active bodies instead disrupt the stable frame of Bond’s voyeurism.
Starting off with an original re-assessment of the cultural roots of Bond’s postwar masculinity, the book argues that Bond Girls emerge from masculine anxieties about the rise of female emancipation after the Second World War and persistent in the present day. Displaying parallels with the politics of race and colonialism, such tensions appear through sartorial practices as diverse as exoticism, power dressing and fetish wear, which reveal complex and often contradictory ideas about the patriarchal and imperial ideologies associated with Bond. Attention to costume, film and gender theory makes Bond Girls: Body, Gender and Fashion essential reading for students and scholars of fashion, media and cultural studies, and for anyone with an interest in Bond.
