A lei 10.639/2003 instituiu o ensino de história e cultura afro-brasileira nos estabelecimentos de ensino fundamental e médio, oficiais e particulares no Brasil. Entretanto, algumas universidades não oferecem este conteúdo em seus cursos de licenciatura, necessitando assim de capacitações como o “Curso Conhecendo a África e fortalecendo nossa identidade”, promovido pela Secretaria Municipal de Educação (Semed)/Maceió, para os/as professores/as da rede municipal, no período de 20 de outubro a 07 de dezembro de 2021. O objetivo deste artigo é relatar a experiência de oferta de três turmas deste curso, na modalidade de ensino híbrido e remoto, com tecnologias digitais. Metodologicamente, descreve-se a experiência, com a reação de cursistas e equipe pedagógica; segue uma abordagem qualitativa, com observação participante; baseia-se em relatos, observações in loco e relatórios finais. O curso possibilitou revisão da história, apresentando o continente africano e sua diversidade histórica e cultural e evidenciando a africanidade no estado de Alagoas e também na capital, Maceió. Conclui-se que, além de possibilitar um conhecimento ampliado da diversidade histórica, cultural e linguística da herança africana que compõe a formação social brasileira, desafiou todos a aprenderem também a utilizar tecnologias nas práticas pedagógicas, mostrando que podemos ser Ubuntu mesmo distanciados e nos mais diversos espaços.
ENTRE PRESERVAR E TRANSFORMAR

Este trabalho trata de práticas culturais das gerações mais novas de uma comunidade quilombola do Sertão nordestino, localizada no município de Água Branca-AL, Brasil. Foram realizadas 11 oficinas com 37 crianças quilombolas e 2 idosos/as. A partir do protagonismo das crianças, foram executadas caminhadas pelo território, rodas de conversas, diálogos intergeracionais, brincadeiras e confecção de brinquedos ensinados por essas gerações. Com as atividades realizadas, os/as participantes mais jovens explicitaram sua identidade quilombola ligada essencialmente ao que fazem no território; envolvendo práticas culturais específicas da sua posição geracional enquanto crianças. Identificamos como exemplos dessas práticas: cantigas populares; brincar de ximbra; confeccionar bonecas e petecas de milho, carrinhos de bananeira e/ou de lata; se envolver (ou não) no artesanato local; cantar e dançar funk. Com base nestas experiências e nos estudos de culturas infantis, compreendemos que, ao mesmo tempo em que as crianças preservam parte da tradição popular, passada de geração em geração, elas também são catalisadoras de algumas transformações culturais locais. Como conclusão, é relevante a desconstrução da imagem generalizada dos quilombos apenas como locus de transmissão e reprodução das tradições, bem como das crianças marcadamente como receptoras da cultura dos/as mais velhos/as.
ESPAÇO, LUGAR E APROPRIAÇÃO EM NARRATIVAS COLONIAIS
Authors: Vilas Bôas Felipe
Published: October 2023

As linhas que seguem são uma tentativa de verificar a potencialidade de se investigar a relação entre espaço e sociedade na região de Kassanje, Angola, no século XIX, buscando compreender a utilização de relatos coloniais para inserir os subsídios espaciais para além de palco de acontecimentos, mas como um elemento importante na construção de narrativas coloniais. Para tal, se lança atenção à narrativa produzida pelo Capitão e Diretor da feira de Kassanje, Antonio Rodrigues Neves, além do breve relato de seu superior, o Major Francisco de Salles Ferreira. Os testemunhos trazem elementos importantes para inferência não apenas por seus conteúdos, mas porque se inserem em uma produção colonial que está intimamente ligada ao contexto de conflitos abertos entre portugueses e africanos no entremeio do século XIX, pautado por ideais do liberalismo e da garantia de forças políticas crivadas por tensões comerciais herdadas da Independência do Brasil, da paulatina queda do comércio de escravizados e de tentativas outras de inserções comerciais em Angola. Tal objetivo permite abrir um leque de questões, como os motivos que levaram a historiografia a não depositar interesse na espacialidade do território Kassanje e tampouco a interação entre espaço e sociedade no contexto colonial africano oitocentista.

Kilka uwag na temat historycznej „perspektywy stołu”
Authors: Kita Jarosław , Korybut-Marciniak Maria
Published: October 2023

Jedenasty tom z serii wydawniczej Życie prywatne Polaków w XIX wieku, opatrzony podtytułem „Perspektywa stołu”, przenosi uwagę na kulturowe i społeczne kwestie spożywania pokarmów, wpisuje się więc w coraz bardziej popularny nurt badawczy – historia jedzenia. Stanowi ogląd życia prywatnego i życia codziennego epoki przez pryzmat praktyk i nawyków żywieniowych oraz szeroko pojętej kultury jedzenia. Analiza życia prywatnego XIX-wiecznych Polaków w kontekście kultury kulinarnej, rytuałów konsumpcyjnych oraz społecznych uwarunkowań wyżywienia nie była do tej pory szerzej podejmowana przez badaczy. Wiek XIX, oglądany przez pryzmat kuchni, wydaje się szczególnie interesujący. Znamionował go szybki rozwój przemysłu i komunikacji (kolej), co dało początek stopniowej niwelacji zjawiska głodu na kontynencie europejskim. Na ziemiach polskich nastąpiło zetknięcie „kuchni polskiej” z kulturami żywieniowymi zaborców. Czy stół polski zachował swoją tożsamość? Czy kuchnia polska miała jakiś wpływ na przetrwanie tej tożsamości? Co zapożyczyliśmy od naszych zaborców? Jakie były smaki emigracji – czy wiązały się również z nostalgią za narodowymi potrawami, czy przeciwnie – nowe doznania smakowe dogadzały polskim podniebieniom? Jakie czynniki miały wpływ na praktyki żywieniowe w poszczególnych grupach społecznych? To tylko niektóre z pytań, na które warto poszukiwać odpowiedzi.
Ojczyzna smakami zapamiętana. Patriotyczno-literacka apoteoza polskiej
Authors: Załęczny Jolanta
Published: October 2023

Opuszczający ojczystą ziemię po powstaniach XIX w., udający się na emigrację czy zsyłani na Sybir zabierali ze sobą najdroższe wspomnienia osób, miejsc, a także zapamiętane smaki, które będą im w każdym czasie przypominać Polskę. Opisywali je potem w pamiętnikach i wspomnieniach, a literaci utrwalili je na kartach powieści i w strofach wierszy. Z dala od rodzinnego kraju próbowali przypominać sobie polskie potrawy, czasem nawet starali się je przygotować, tworząc w ten sposób namiastkę ojczyzny. Na sposób polski urządzano wigilię i święcone. Niektóre przepisy weszły do kanonu literatury polskiej i nieodłącznie wpisały się w patriotyczno-literacką apoteozę polskiej kuchni, tworząc kanon polskiej kuchni narodowej. Mistrzem był tu Adam Mickiewicz, którego opisy potraw i zastawy stołowej utrwalone na kartach narodowej epopei weszły na trwałe do historii literatury, ale też zbudowały wyobrażenie ojczyzny poprzez smaki i zapachy potraw uznawanych niemal za narodowe.

„Jarskie uzdrowisko” w Bojarowie i jego twórca Konstanty Moes-Oskragiełło
Authors: Śmiechowicz Anna
Published: October 2023

W drugiej połowie XIX w. na ziemiach polskich pojawił się ruch jarski odwołujący się do ideologii uzdrowienia uciemiężonych narodów poprzez odnowę ducha i ciała. Propagatorem tej nowatorskiej myśli w latach zaborów był Konstanty Moes-Oskragiełło, który pierwotnie poszukiwał w tej idei lekarstwa na swoje wątłe zdrowie. Działał on prężnie w kwestii popularyzacji wegetarianizmu w Warszawie i Krakowie, a zwłaszcza w Bojarowie koło Otwocka. Stworzył tam w 1883 r. uzdrowisko, gdzie jedną z metod leczenia była dieta pozbawiona produktów mięsnych.
„Żołnierski wikt” w wojsku polskim w 1807 roku
Authors: Srogosz Tadeusz
Published: October 2023

Podczas stacjonowania w koszarach lub na kwaterach, kiedy dochodziły regularnie dostawy, dzienna racja żywnościowa w wojsku polskim była wystarczająca. W warunkach polowych, zwłaszcza zimą i na przednówku, odżywienie żołnierzy pogarszało się gwałtownie. Kraj, ogołocony wojną i rekwizycjami, nie mógł wyżywić znacznej liczby żołnierzy skoncentrowanych na niewielkim obszarze. Brak szczegółowych danych nie pozwala określić wysokości konsumpcji alkoholu przez żołnierzy, jednak można przypuszczać na podstawie źródeł pośrednich, że była ona wyższa niż w całym społeczeństwie. Żołnierski wikt w lazaretach kształtował się podobnie jak podczas stacjonowania.
Urzędniczy wikt. Sytuacja materialna urzędników administracji państwowej w Imperium Rosyjskim w XIX wieku
Authors: Kowalik Jolanta
Published: October 2023

Świat urzędników państwowych Imperium Rosyjskiego był pełen regulacji prawnych. Od początku ścieżki kariery (która miała swój przebieg zgodnie z tabelą rang), po strój i uposażenie pracownika, wszystkie te aspekty musiały być zatwierdzone przez samego cara. Wzrost liczby służby cywilnej w Imperium Rosyjskim w XIX w. nie był proporcjonalny do wzrostu wydatków państwa na administrację urzędów. Skutkowało to niskimi płacami, zwłaszcza dla pracowników, którzy przychodzili w dużej liczbie do ministerstw i urzędów centralnych. Ich ledwie „życiowe” wypłaty zapewniały jedynie minimum niezbędne do życia, w związku z czym wydatki na podstawowe środki do życia, w tym żywność, również były skromne i często nie zaspokajały podstawowych potrzeb fizjologicznych człowieka. Jednak urzędnicy wyższego szczebla zajmujący stanowiska ministerialne lub wojewódzkie znajdowali się w innej sytuacji materialnej. Zarobki pozwalały im na prowadzenie wyższego standardu życia, co wiązało się także ze spożywaniem urozmaiconych posiłków, nie tylko w domu, ale także w restauracjach, klubach i na organizowanych przez nich imprezach. Badania nad kuchnią urzędników Imperium Rosyjskiego w XIX w. stały się pretekstem do prześledzenia warunków ich codziennego życia i kosztów utrzymania, co dowodzi panujących nierówności ekonomicznych w tej grupie społecznej. Analiza tematu została przeprowadzona na podstawie dostępnych źródeł archiwalnych, wspomnień i literatury.
Przykłady wykwintnej kuchni dworskiej księcia żagańskiego Napoléona Louisa (Ludwika) de Talleyrand-Périgord w latach 1878–1894
Authors: Głowania Katarzyna
Published: October 2023

Artykuł omawia sferę praktyk życia codziennego w drugiej połowie XIX w. poprzez analizę zwyczajów żywieniowych rodu Talleyrand-Périgord. Podstawę analizy stanowią wydatki książęcej kuchni dworskiej z Żagania za czasów księcia Ludwika Napoleona de Talleyrand-Périgord (1863–1898). Rodzina książęca dzieliła swój czas między Paryżem, posiadłością w Valençay, mieszkaniem w Berlinie a pałacem w Żaganiu na Dolnym Śląsku. Hucznie obchodzono tutaj zarówno uroczystości rodzinne (urodziny księżnej Pauliny), jak i wydarzenia towarzyskie, zwłaszcza w 1881 r. (ślub córki księcia „Dolly”) i 1886 r. (100-lecie zakupu księstwa żagańskiego przez księcia kurlandzkiego Birona), w których uczestniczyli znamienici przedstawiciele arystokratycznych rodów europejskich. Przy uroczystych posiłkach wzrastała wykwintność potraw. Zamawiano wówczas luksusowe produkty, jak ananasy, wanilia, czekolada, strasburskie pasztety czy grzyby trufle z południowej Francji. W wydatkach bardzo często pojawiały się produkty lokalne sprowadzane z całej Europy, jak tyrolskie jabłka, helgolandzkie homary, holenderskie ostrygi, brukselskie pulardy, angielska szynka czy włoski makaron. Książę żagański dbał nie tylko o jakość posiłków, ale i o wystrój jadalni, jej wyposażenie i liberie lokajów podających posiłki. Szczególną uwagę przywiązywał do profesjonalnego przygotowywania posiłków. Co istotne, wysoką pozycję księcia podkreślała nie tylko staranność przygotowywania posiłków w kuchni dworskiej i podawania ich przy stole. Wszystkie te elementy tworzyły kulturę jedzenia i podkreślały wytworność żagańskiego stołu.
„Woli w Polszcze leda schaby / Niż tu ostrygi i żaby / „Woli zraz pieczeni spory / Niźli kaulafiory”. Kuchnia włoska w oczach polskich peregrynantów
Authors: Szadkowska-Mańkowska Olga
Published: October 2023

Kulturowe relacje Polski i Włoch na przestrzeni wieków stanowiły (i stanowią nadal) ważny element w podejmowanych dyskusjach historyczno-literackich. Nie ulega wątpliwości, że italianizm – pojęty bardziej jako sposób postrzegania Włoch, wynikający z roli odgrywanej przez Italię w kulturze Zachodu, niż jako doktryna na temat Włoch – oznaczał całkowicie nową koncepcję zwiedzania. Co ciekawe, nie tylko architektura, malarstwo, rzeźba czy wyjątkowo sprzyjający klimat włoski budziły emocje u polskich peregrynantów. W kręgu ich zainteresowania pozostawała również kuchnia włoska. Miłość do kuchni włoskiej nie jest tematem jednorodnym – solidnym mięsiwom i godnym napitkom polskim często przeciwstawiana była „wykwintność” włoska. Tradycjonaliści społeczeństwa polskiego, tkwiący w kulcie starego obyczaju, nie wychylający się poza granice polskie, z pewnością przysłużyli się kiepskiej sławie włoskiej mody, w tym włoskiej kuchni. I chociaż większość głosów dotyczących cieni i blasków potraw z Italii należy do mężczyzn, ci bowiem podróżowali częściej, to ciekawym źródłem do analizy codzienności w podróży są wspomnienia kobiet-peregrynantek. Teofilia Morawska, Waleria Tarnowska czy Katarzyna z Sosnowskich Platerowa to przykłady podróżniczek polskich przełomu XVIII i XIX w., które wzbogaciły tę tematykę swoimi rozważaniami. Niezależnie od celu i powodu podróży kobiecej, każda z nich na swój sposób poszerzała horyzonty i przyniosła doświadczenie bezcenne w życiu człowieka. To, z czym się stykały opisywały w sposób zrównoważony, snuły spokojne refleksje, ponieważ odczuwały pełną więź z Europą Zachodnią i jej życiem. Niejednokrotnie włączały one rzeczywistość kraju, który znały – również od strony „stołu”. Czy rzeczywiście „kuchnię włoską pokochaliśmy dopiero w XX w.?” W artykule podjęto także zagadnienie polskiego stosunku do kuchni włoskiej w pamiętnikach kobiet z podróży początków XIX w.
Liderazgo distribuido en escuelas públicas y relación con sus categorías de desempeño
Authors: Galaz Moraga Elisabeth , Verdugo Peñaloza Alejandro
Published: October 2023

El liderazgo distribuido es considerado uno de los nuevos modelos de liderazgo en educación ya que permite un trabajo colaborativo, de relaciones horizontales, que favorece la confianza de liderazgos internos, abordando de mejor manera esta sociedad globalizada, compleja y acelerada. Esta investigación busca analizar las percepciones sobre los patrones del liderazgo distribuido de directivos y docentes, estableciendo si existe relación con las categorías de desempeño de las unidades educativas estudiadas. Se adopta un paradigma positivista, de enfoque cuantitativo y tipo correlacional, que considera la participación de 27 directivos y 73 docentes de escuelas públicas de la ciudad de Antofagasta. La recogida de información es por medio de un cuestionario con preguntas tipo Likert. Los resultados muestran que los patrones de distribución del liderazgo formal, pragmático y estratégico son los que están presentes en las unidades educativas; además, los directivos perciben de mejor manera el liderazgo distribuido que los docentes y se establece que existe relación entre las categorías de desempeño y los patrones estratégico e incremental. Este estudio aporta al diagnóstico del liderazgo distribuido, considerado escaso en el país y coincide con otro estudio previo en cuanto a los patrones de liderazgo distribuido presentes y ausentes, además de la percepción más favorable de directivos por sobre docentes.

Authors: Adamiak Borys , Szczotka Andrzej , Woodburn Joseph , Merkisz Jerzy
Published: October 2023

Exhaust emissions testing of vehicles under real driving conditions (real driving emissions, RDE) using portable exhaust emissions measurements systems (PEMS) was introduced a few years ago by the European Commission as a mandatory test during type approval and later also for in-service conformity. This paper compares results from mobile systems for measuring exhaust gas emissions (PEMS) with a stationary laboratory (BOSMAL’s Exhaust Emissions Testing Laboratory). The tests were carried out using a passenger car equipped with a spark ignition engine, which was tested on chassis dynamometer over the WLTC cycle. The results showed that the differences between PEMS analysers and stationary analysers range from a few percent to a dozen or so percent, depending on the component and the measurement method.

Published: October 2023

Stretchable energy-storage devices are required to power next-generation wearable electronics intimately integrated with the human body. The microbatteries and microsupercapacitors represent promising candidates featuring small footprints and facile system integration. This perspective reviews common strategies to convert conventional rigid devices into stretchable forms. Several prototype soft electronic systems are presented utilizing microbatteries and microsupercapacitors as power sources. We discuss the current challenges and perspectives of the stretchable microbattery and microsupercapacitor. Stretchable forms of miniaturized energy-storage devices often show a significant trade-off between mechanical deformability and electrochemical performances, which present attractive opportunities for the material and engineering community.

Published: October 2023

» The quadriceps tendon (QT) autograft is becoming increasingly popular in both primary and revision anterior cruciate ligament reconstruction (ACLR).

» The biomechanical properties of the QT are similar to those of the native ACL, the hamstring tendon (HT), and bone-patellar tendon-bone (BTB) autografts.

» QT autograft allows surgeons to be flexible with their graft size and reconstruction technique.

» The QT autograft performs in a similar fashion to the BTB and HT autografts, with excellent patient-reported outcomes, consistent postoperative knee stability, and low rates of postoperative complications including graft failure and donor site morbidity.

» There are emerging data that the QT autograft is a viable option in revision ACLR.
Equity and employability: A study into the challenges faced by healthcare learners with a disability and/or learners pursuing part-time work
Authors: Taylor Lisa , Chandler Charmaine , Jong Stephanie
Published: October 2023

An increasing amount of evidence suggests that learners within Higher Education (HE), and graduates, are struggling with their transition into the workplace. With the increased prominence of workplace learning requirements, these challenges are becoming more evident for learners during HE studies. This study aimed to identify the challenges faced by learners and graduates transitioning into the healthcare workforce, and the challenges experienced by key groups such as healthcare employers and other influencers within HE. The key focus was on disability, part-time work and transitions into the workplace. Thirty-two individuals participated in an online survey focused on equity and employability. Questions were both quantitative and qualitative in nature. Participants were learners, graduates, academics, career advisory staff, and employers. Thematic analysis of the qualitative data identified eight themes.
Challenges identified by participants included work-life balance, stigma and stereotypes, organisational and individual empowerment, navigating additional administrations tasks, information and signposting, consistency in language and messaging, advocacy, and exemplars for guidance. The study highlights the responsibilities of all involved with HE provision, and the importance of collaboration with employers to inform, educate and advocate for all learners to maximize employability opportunities and enhance transitions into employment. Policy and practice in this area should quality assure the robustness of the support, aiming to meet individual needs, including education to empower and facilitate individual agency, as well as reviewing the visibility and accessibility of resources.
Multiple Production Time Series Forecasting Using Deepar and Probabilistic Forecasting
Authors: Han JiangXia , Xue Liang
Published: October 2023

The majority of production forecasting methods currently used are point forecasting methods developed in the setting of individual well forecasting. For an actual oilfield, instead of needing to predict individual production time series, one is faced with forecasting thousands of related time series and the uncertainty can be assessed. The objective of this work is to enable global modeling and probabilistic forecasting of a large number of related production time series using Deep Autoregressive Recurrent Neural Networks (DeepAR). The DeepAR model consists of three parts. First, the auxiliary data such as static classification covariates and dynamic covariates are encoded. Second, establish a forward model based on an autoregressive recurrent neural network. Third, the normal distribution is defined as the output distribution function. And the variance and mean are obtained by solving the maximum log-likelihood function using the gradient descent algorithm. We demonstrate how the application of DeepAR to forecasting can overcome many of the challenges(e.g. frequent well shut-in and opening, probabilistic prediction, classification prediction) that are faced by widely-used classical approaches to the problem. In this work, history fitting and prediction were performed on a dataset from more than 2000 tight gas reservoir wells in the Ordos Basin, China. The DeepAR and conventional methods were tested and compared based on the datasets. We show through extensive empirical evaluation on several real-world forecasting data sets accuracy improvements of around 30% compared to RNN-based networks. In the case of frequent well shut-ins and openings, the RNN-based network structure cannot capture the fast pressure response and extreme fluctuations, which eventually leads to high errors. In contrast, DeepAR is more stable to frequent or significant well variations, can learn different dynamic and static category features, generates calibrated probabilistic forecasts with high accuracy, and can learn complex patterns such as seasonality and uncertainty growth over time from the data. This study provides more general production forecasting and analysis of production dynamics methods from a big data perspective. Instead of performing costly well tests or shut-ins, reservoir engineers can extract valuable long-term reservoir performance information from predictions estimated by DeepAR trained on an extensive collection of related production time series data.
Estimation of Water Cut, Gas Oil Ratio and Inflow Parameters for Deep Water Wells with Infrequent Well Tests Using Regression-Based Method
Authors: Nandanwar Manish , Lolla Sri , Pareek Aditya , Pandya Rohan , Gupta Robin , Kedia Kushal
Published: October 2023

Real-time production surveillance and optimization requires availability of predictive well models with reasonable accuracy that can estimate production rates in response to change in operating conditions. These models that are mostly physics based are parameterized in terms of gas oil ratio (GOR), water cut (WC), productivity index (PI), and reservoir pressure. Further, the models are tuned using measured data namely production rates of oil, water, gas, and pressure measurements such as downhole gauge pressure, wellhead and flowline pressures that are captured during a well test. For mature oil fields where, well tests are infrequent or sensors start malfunctioning, relevant data required for model tuning is no longer available. In absence of updated models, real-time predictions tend to deviate with time compared to the observed data resulting in less reliable well rate allocation and production optimization recommendations, if any. This work describes a regression-based technique and its application for predicting quantitative as well as directional changes in well parameters between well tests that can be used to improve well allocations.

A regression method that estimates well parameters while minimizing a non-linear least square loss function derived from deviation between measured and model-based estimates of rate and pressure data is implemented. The method can estimate well parameters for both an individual and multiple wells simultaneously while solving for a network of wells connected to production separator using IPM GAP. The application of the method to a subsea asset is demonstrated while evaluating its performance for different scenarios comprising variation in number of wells and well parameters. Additionally, the capability of the method to predict directional changes in well parameters is demonstrated by validating it against historical data.

The estimates from regression method were found within 5% difference compared to well parameters obtained from multiphase flow meters for the scenarios where number of wells and the number of regression parameters per well were limited. This difference increased with increase in number of wells and number of regression parameters per well owing to the fact that solution space expands with increased degrees of freedom. However, the directional changes in parameters were predicted accurately when looked at larger time scales. It was inferred that the application of regression method is best suited for the scenarios where well parameter estimations are needed for a limited number of wells and the parameters for the remaining wells in a network are representative. Additionally, availability and reliability of sensor data largely impacts the method outcomes.
Detection of Leaky Pneumatic Actuators in Real-Time for Fugitive Methane Emissions Management
Authors: Adeyemi A. K. , Younis R. M. , Keller M. W. , Lynch P. K.
Published: October 2023

Pneumatic actuators are pervasive in oil and gas infrastructure, from wellhead sites to transmission lines. Domestic field studies (industry and government stakeholders) identify them as the leading culprit for unintended fugitive methane leaks. We developed a real-time computational approach that utilizes streaming observations of an actuator’s inlet pressure, rate, and displacement to identify whether it is leaky. The approach can be used in integrated modeling workflows to account for the implications of controls on emissions.

Our approach is informed by the fluid-structure interaction (FSI) between compressible gas flow and diaphragmatic elastodynamic. Canonical models are established with a dimensionless parameter space, given cataloged device specifications. High-fidelity three-dimensional FSI simulation is applied to generate a large synthetic dataset spanning operations of the pneumatic actuator under normal and dysfunctional settings. The dataset provides a statistically meaningful sampling of diaphragm rupture events during transient and steady periods with the addition of noise to account for measurement errors and background vibration. Dimensional analysis is applied to design predictor features, and several supervised-learning methods are applied within a hyper-parameterized dimensionless space.

Training, validation, and testing are performed, and confusion matrices and prediction accuracy are computed to assess the predictive capacity of the methods. The accuracy of the methods ranged between 80% and 97% for binary leak/no-leak predictions. Predictions for multicategory leaks (tear geometry and size) show improved accuracy with tear size. Combined pressure transient and elastodynamic predictors improve performance significantly compared to the use of acoustic data only. Generalization within the spectrum of relatively narrow designs is promising.

Previously reported leak detection methods exploited the dynamics of rapid negative pressure waves as a key discriminator. However, given the rapid timescales and sensitivity to sensor location, predictive accuracy is limited. This work augments acoustics with mechanics to obtain a stark improvement in predictive accuracy. Furthermore, the predictors are evaluated exclusively using process flow observations and device specifications, rendering our methods amenable to use in integrated surface facility models and SCADA systems.
Stuck Pipe Prediction in Utah FORGE Geothermal Wells

Published: October 2023

Four stuck pipe events occurred during the construction of six geothermal wells in the Utah FORGE field, causing several hours of non-productive time (NPT). All of them could have been avoided if effective preventive measures and tools had been used. This paper provides an analysis of these events with the publicly available Utah FORGE dataset and discusses their predictability using a new hybrid approach that can in future be used to avoid stuck pipe incidences at Utah FORGE.

Our analysis is primarily based on physics-based simulations combined with well information, such as trajectory, lithology, and the position of the drillstring (specifically the contact points) with respect to the geometry during the time the events occurred. Based on this detailed analysis, we implemented anomaly detection techniques in the time window before each stuck pipe event to automatically identify root causes. Following this, we formulated guidelines that combine the developed early stuck pipe event detection capability with accepted industry operational practices, to prevent similar stuck events in the future.

The Utah FORGE stuck pipe events were found to be primarily related to wellbore geometry (i.e., mechanical stuck pipe) and use of non-optimum operational drilling practices. The incidents, analyzed in time domain after dimensional transformations, show clear early signs of anomalies in the time frame before their occurrence. This means they could have been detected and potentially prevented. The guidelines include recommendations for acting pro-actively on early stuck pipe indicators identified by real-time data analysis, as well as making appropriate additional changes during well planning and execution phases, such as changing the bottom hole assembly to be less sensitive to mechanical sticking. The work shows the high value of robust predictive models for stuck pipe prevention.

The work will help reduce geothermal well construction (which is expected to expand significantly in the near future) cost by enabling better stuck pipe NPT avoidance. However, the approach is not specific to geothermal well construction and can be expanded to all drilling applications as well as stuck pipe incidents that are non-geometrical in origin. This paper therefore provides a new real-time data analysis system and effective guidelines which, if implemented, will enable better mitigation of stuck pipe risks on future wells.

This paper aims to demonstrate the transferable skills of oil and gas professionals relevant to the energy transition and low-carbon technologies. We examined both core technical and non-core technical skills.

The approach to this study involved using the SPE competency matrix for oil and gas professionals and mapping it against the different concepts related to decarbonization and renewable energy sources. We covered core technical and non-core technical oil and gas skills, and how they related to concepts such as carbon capture and sequestration, underground energy storage, rare earth elements, and renewable energy. We graded each item in the oil and gas competency matrix to demonstrate how relevant they were to the low-carbon technologies. We referenced case studies in research where oil and gas skills are being used in several aspects of the energy mix.

The results showed that the technical competencies of oil and gas professionals were most useful in areas such as carbon storage, underground energy storage, and geothermal energy. The study also showed that geoscience skills cut across almost every aspect of low-carbon technologies and other concepts related to the energy transition. We also observed that non-technical competencies such as project management, HSE (health, safety, and environment), and business development skills cut across all low-carbon technologies and were very relevant for renewable energy resources like solar, wind, and hydro. Data science and digital skills were seen to be applicable to all low-carbon energy technologies. Using the case studies, we discuss the required upskilling, reskilling, and cross-skilling.

The novel deliverable of this study is a comprehensive skillset map that shows where the oil and gas skills fit within low-carbon energy technologies. Professionals with skills in geosciences, reservoir engineering, production engineering, drilling, and wells engineering can see what areas they can easily transfer their skills, where they require reskilling, and where upskilling will be required. This could help organizations design a reskilling and upskilling strategy to help oil and gas professionals remain relevant in the energy transition.
Real-Time Performance Optimization Using Temperature Derived Rates to Prevent Productivity Decline
Authors: Izgec Bulent
Published: October 2023

This work presents a well performance analysis technique that identifies formation damage and/ or productivity loss real-time using rates derived from measured well temperatures. It also provides insights into expected damage mechanisms enabling efficient stimulation treatments.

The analytical technique recognizes damage patterns at inception. The diagnostics to drive operational decisions are then presented as simple cartesian plots that grant easy access to users of all levels of experience. Data driven temperature-to-rate models provide continuous conversion of flowing well temperatures to production rates that help automate diagnostics for optimum daily surveillance.

Case studies from several deepwater wells demonstrate how the technique has been successfully operationalized to eliminate productivity losses, gain early insight into damage mechanisms, and investigate the impact of well interventions. Evaluations and comparisons using pressure transient analysis (PTA), rate transient analysis (RTA) and numerical history matching studies conducted with and without temperature derived rates corroborate the robustness of the method. Temperature derived rates exhibit less than 3 % error when compared to well tests, multi-phase, and ultrasonic flow meters.

Shutting in the wells is not required for the analysis, therefore lost production and additional stress cycles on the completion are eliminated. The analysis identifies the maximum drawdown limit, thereby helping the operator optimize well performance real-time. In addition, a data driven approach is outlined for estimating PTA equivalent skin values without shutting-in the wells. Data driven temperature-to-rate models can be developed and maintained with little effort to improve rate allocations, cut back on metering costs, and reduce operational complexities associated with increased number of tests.
Multibarrier Integrity Evaluation in a Field with Active Faulting – A Case Study
Authors: Kotlar N. , Castro Chacon A. , Jimenez Gomez J. A.
Published: October 2023

The producing basins located in Los Andes region of Colombia are often subject to active tectonic stresses and severe faulting. This is exacerbated by uneven formation pressure due to preferential depletion or injection. Due to the large horizontal stresses, the casing often deforms plastically, resulting in buckling, shearing and ovalization. Consequently, the ability to re-entry the well may be compromised, the production can be impacted, and the mechanical properties of the tubulars can also be affected.

The well presented in this study was evaluated using Multifinger Caliper, Electromagnetic thickness measurements and Segmented cement tools. The presence of casing deformation is sometimes masked by the processing steps involved in the data conditioning of the internal radius measurements. Multifinger caliper data automatically corrected for eccentricity does not show obvious signs of deformation, although the pipe tortuosity can be severe. In this well, different deformation mechanisms are identified, and a procedure is proposed to characterize the type and magnitude of these events. Apart from corrosion and internal casing wear, the remnant mechanical properties of the pipe are also impacted by deformation and might result in reduced burst and collapse ratings. Electromagnetic thickness data is used to evaluate this aspect.

Integrating the multifinger caliper results with the cement evaluation logs show that the main deformed intervals lack of annular cement isolation. This was key to understanding the nature of the faults, that not only contribute to well deformation, but are also conductive pathways that lead to fluid and cement losses.

Correlating the deformed intervals and sections with poor cement with the geological descriptions of the field allows identifying, and sometimes predicting, problematic faults and potential high-stress regions of the formation. This has an immediate impact on the field development plans, well design and surveillance programs. Moreover, by establishing a clear workflow to identify and characterize deformation through internal radius evaluation (multifinger caliper or ultrasonic logs), the analysts are better equipped to face similar situations in future evaluation jobs, and also capable to re-analyze existing logs in the field.

This study highlights the value of data integration in cased hole logging integrity evaluation. The combination of the casing integrity and cement logs leads to a deeper understanding of the fields' faulting and stresses, which allows identifying wells that require interventions and integrity evaluation, and is vital information for the management of the reservoir and future well placing.
Beyond API: How to Evaluate Industry Standards for Practical Applications Improving Cementing Fluid Designs and Testing Accuracy

Published: October 2023

A standard can represent the foundational instruction for performing any task consistently and enabling repeatable results. Laboratories as well as personnel can apply the practices and techniques documented in standards without the knowledge of the intent – how it relates to managing the risk at the wellsite and achieve the execution success. Within standards there can be instructions which resulted from field experience helping to improve the representative test conditions in the laboratory to overcome risks previously identified. As well operations evolve, cement placement and the resulting laboratory testing evolve aligning with standard organizations using a reaffirmation process for documents over time. As standards tend to omit acceptance or evaluation criteria due to differences of opinion across the industry or potential misinterpretation by regulatory agencies, the manuscript serves as a complimentary document helping to identify risks during wellsite execution and a means to optimize designs with suggested evaluation criteria as well as test method modifications when applicable.
