An End-To-End Machine Learning Project for Detection of Stuck Pipe Symptoms During Tripping Operations
No full textNon-productive time due to stuck pipe costs the Oil and Gas industry substantial losses amounting to $250 million annually [1]. Thus, it is imperative for companies to invest in tools that can aid in prevention. This study integrates different concepts and methodologies from Petroleum Engineering, Data Analysis, and Machine Learning (ML). It aims to identify and extract hook load signatures before a stuck pipe event that can be used to train an ML model. The lack of transparent and consistent frameworks in many published papers using the same approach proved to be a problem. Hence, it is also our aim to present all the algorithms used.
In a Machine Learning project, data preparation accounts for about 80% of the work [2, 3]. For this reason, the author developed two web-based applications for cleaning and exploring raw drilling data. These provided time savings given the time constraints of this project.
Once the data was prepared, maximum and local minimum hook loads were extracted for tripping out and tripping in operations, respectively. During the study, a new concept for extracting the local minimum hook load was developed. It was able to identify the trend deviation as early as 4 hours and 30 minutes before the reported stuck pipe. Furthermore, all the extracted maximum and local minimum hook loads distinguished trend deviation between normal and deteriorating downhole conditions. This was not possible when basing solely on the real-time hook load.
Moreover, a long short term-memory network was trained using 50% of the extracted hook load signatures. This model was designed to predict and identify hook load trends during tripping operations. Then using the remaining data, the model was evaluated. Results showed that the model predicted hook loads with a mean absolute error of <3% from the average expected value. The model also resembled trends with a delay of utmost 20 minutes or six stands, particularly during the deteriorating conditions. Despite the model failing to forecast, it detected a deteriorating condition three hours before the stuck pipe incident. These results were heavily dependent on the amount and quality of data. Out of seven wells provided, only three were functional, having at least 0.2 Hz of measurement.
Further studies involving gathering more high quality drilling data and retraining the model are recommended to be able to create a model capable of forecasting the trend deviations earlier than the currently developed model
A alteridade e a espiritualidade dos universitários potiguara da Paraíba
No full textThis is the first PPGCR research produced by a Potiguara of Paraíba to understand how the
relations of the academic universe and the spirituality dimensions of the Potiguara indigenous
university students build their ethnic alterity and their traditional knowledge within the
university, as these university students practice the scientific knowledge within the indigenous
village. This research has a goal to investigate the actions of Potiguara university students in
the continuity and preservation of their alterity and ethnic spirituality as indigenous people,
both in the academy and in the indigenous village. The main theorists.are: Barcellos (2014),
Eliade (2002); Santos (2009); Palitot (2005), Vieira (2010); Mendonça (2014); Silva (2011);
Sousa (2017), among other theorists. This is an ethnographic research with a qualitative
approach, presenting the self-ethnography character because the author is a member of the
Potiguara nation. As research instruments were used the participant observation since in the
indigenous universe, the presence in loco is primordial to investigate the object of the study;
the field diary with all notes, the scripts, the restlessness with the indigenous people; the semistructured interviews that are essential to deepening the featured themes in the research. As a
result, the study revealed that the Potiguara university students continue to cultivate their
alterity and spirituality, the two primordial elements of the indigenous culture, offering a
recommended return for the strengthening of their myths and ethnic rites. Despite the
individualistic aspect of the University, it was identified that the indigenous university students
accept their Potiguara identity, as well, the collectivity spirit, within the University, thus being
able to return to their indigenous village, bringing the scientific knowledge to contribute with
your community. How this will happen, time will reveal!IMOMIRĨ: Iî ypýramo, PPGCR rupi, kunhã Potigûara Paraibygûara porandu-randúbi Potigûara

apresenta como objeto: compreender a práxis dos(as) universitários(as) indígenas Potiguara. Na
tentativa de apreender como as relações do universo acadêmico e as dimensões da
espiritualidade dos(as) universitários(as) Potiguara edificam sua alteridade étnica e seus
conhecimentos tradicionais dentro do espaço acadêmico, bem como, tais discentes praticam os
saberes científicos dentro das aldeias. Tem como objetivo investigar as suas ações na
continuidade e a preservação de sua alteridade, bem como, da espiritualidade étnica enquanto
indígenas, tanto na academia, como na aldeia de origem. Os principais aportes teóricos são:

Mendonça (2014); Silva (2011); Sousa (2017), dentre outros. Trata-se de uma pesquisa
etnográfica, com abordagem qualitativa, apresentando caráter da autoetnografia, por ser a
autora membro do povo Potiguara. Como instrumentos de pesquisa foram utilizados a
observação participante, uma vez que no universo indígena é primordial a presença in loco para
investigar o objeto de estudo; o diário de campo, a fim de fazer todas as anotações, os roteiros,
as inquietações junto aos(as) indígenas e as entrevistas semiestruturadas, essenciais para
aprofundar as temáticas em destaques da pesquisa. Como resultados, o estudo revelou que
os(as) universitários(as) Potiguara continuam cultivando a sua alteridade e espiritualidade,
elementos primordiais da cultura indígena, oferecendo retorno preconizado para o
fortalecimento de seus mitos e ritos étnicos. Mesmo com o aspecto individualista da
universidade, foi identificado que os(as) universitários(as) indígenas assumem a sua identidade
Potiguara, assim como o espírito de coletividade, dentro da academia, podendo assim voltar
para a sua aldeia de origem, levando conhecimentos científicos para contribuir com o seu povo.

Cellular accumulation and toxic effects of bile acids in cyclosporine A-treated HepaRG hepatocytes
No full textInternational audienceAlteration of bile acid (BA) profiles and secretion by cholestatic drugs represents a major clinical issue. Species differences exist in BA composition, synthesis and regulation; however presently, there is no in vitro reproducible cell model to perform studies on BAs in humans. We have evaluated the capacity of the human HepaRG cell line to synthesize, conjugate and secrete BAs, and analyzed changes in BA content and profile after cyclosporine A (CsA) treatment. Our data show that HepaRG cells produced normal BAs at daily levels comparable, though in different proportions, to those measured in primary human hepatocytes. A 4h treatment with CsA led to BA accumulation and profile changes associated with occurrence of cholestatic features, while after 24h BAs were decreased in cell layers and increased in media. The latter effects resulted from reduced function of BA uptake transporter (NTCP), reduced expression of BA metabolizing enzymes, including CYP7A1, CYP8B1 and CYP27A1, and induction of alternative basolateral transporters. Noteworthy, HepaRG cells incubated in a 2% serum-supplemented medium showed dose-dependent accumulation of the cytotoxic BA lithocholic acid in a nonsulfoconjugated form associated with early inhibition of the canalicular transporter MRP2 and sulfotransferase 2A1. In summary, our data bring the first demonstration that an in vitro human liver cell line is able to produce and secrete conjugated BAs, and to accumulate endogenous BAs transiently, concomitantly to occurrence of various other cholestatic features following CsA treatment. Retention of the hydrophobic lithocholic acid supports its toxic role in drug-induced cholestasis. Overall, our results argue on the suitability of HepaRG cells for investigating mechanisms involved in the development of the diseas
