Development of ICT competence among students when teaching inverse problems for differential equations with the use of computer technology
Authors: Kornilov Viktor S.
Published: February 2020

Problem and goal. The great need to apply the theory of inverse problems for differential equations (IP) in the research of applied problems is explained by the fact that it is possible to effectively study hard-to-reach or inaccessible objects and processes, to identify, for example, the location of objects, determine their shape, etc. In addition, it is possible to identify causeand-effect relationships of processes and phenomena (see, for example, [5; 6; 8; 11; 14; 17; 19]). It became possible, in many respects, thanks to modern computer technologies which allow to investigate various mathematical models of inverse problems, realize modern computational algorithms of the numerical solution of inverse problems for differential equations, carry out three-dimensional visualization of their decisions and control of accuracy of calculations. This circumstance explains the widespread introduction of modern computer technologies in the process of teaching students of IP educational institutions of physics and mathematics (see, for example, [2; 5; 6; 8; 10-14; 17; 19; 20]). In the process of teaching, goals are set to ensure that students form a system of fundamental knowledge in the field of theory and practice of inverse problems, applied and computational mathematics, acquire the skills to choose and apply computer technology to find solutions to inverse problems, develop their ICT competence. Methodology. The development of ICT competence among students of universities of physical and mathematical areas of training, as a result of learning IP, is ensured by how successfully the conditions will be implemented in practice, including: 1) involvement of specialists in the field of inverse problems for differential equations with experience in the use of computer technology in the study of inverse problems; 2) conducting lectures and practical classes using multimedia and computer technologies; 3) implementation of didactic principles of teaching inverse problems for differential equations using computer technologies; 4) attraction of students to performance of semester tasks, course and final qualifying works on inverse problems for differential equations with use of computer technologies. Results. In practical classes, students acquire the skills to apply modern computer technology in the study of IP. Students gain experience in analyzing new information about the studied physical processes and phenomena using computer technology. Students form knowledge about the role of computer technology in mobile research of mathematical models of inverse problems for differential equations, demonstrating ICT competence. Conclusion. Developed in the process of teaching inverse problems for differential equations using computer technologies, ICT competence will obviously allow students in their future professional activities to effectively apply a variety of computer technologies in the study of mathematical models of inverse problems.

Authors: Escallón-Portilla Andrés Felipe , Ruiz-Guachetá Víctor Hugo , López-Perafán José Giovanny
Published: February 2020

Este artículo propone el diseño y simulación de un módulo de radio frecuencia basado en un sistema de multiplexación por división de frecuencia ortogonal (OFDM) con modulación de amplitud en cuadratura (16-QAM) a una tasa de transmisión de datos de 10 Gbps y a una frecuencia de 10 GHz, utilizando la herramienta de simulación OptSim. Para ello, se diseñó a nivel de simulación un sistema de red con fibra hasta el hogar (FTTH)-óptica pasiva Gigabit (GPON) Triple Play (servicio de datos/voz a 2,5 Gbps y servicio de video CATV digital con 16-QAM a 0,8 Gbps) con el fin de integrar el módulo de radio sobre fibra (RoF) para ofrecer servicios Quad Play (Triple Play más Internet móvil). Posteriormente, se evaluó el desempeño para el enlace descendente a nivel físico del sistema FTTH-GPON después de que se incorporó el módulo RoF, con base en los parámetros de monitoreo de desempeño óptico (OPM), tales como: potencia de recepción óptica, magnitud del vector de error (EVM), diagrama de constelación, relación señal a ruido (SNR), tasa de error de bit (BER), Factor de calidad (Q) y diagrama del ojo. Los resultados muestran que es posible que los usuarios de las redes FTTH-GPON puedan contar, además de los servicios Triple Play, con un cuarto servicio (Internet móvil) ya que la calidad del servicio móvil está garantizada dentro del “último kilómetro” para redes de acceso, usando el despliegue actual de fibra óptica estándar, demostrando la factibilidad del sistema propuesto.

Published: February 2020

Las redes sociales acumulan gran cantidad de información. Las actuales técnicas de Procesamiento de Lenguaje Natural permiten su procesamiento automático y las técnicas de Minería de Datos permiten extraer datos útiles a partir de la información recopilada y procesada. Sin embargo, de la revisión del estado del arte, se observa que la mayoría de los métodos de clasificación de los datos identificados y extraídos de redes sociales son biclase. Esto no es suficiente para algunas áreas de clasificación, en las que hay más de dos clases a considerar. En este artículo, se aporta un estudio comparativo de los métodos svm y Random Forests, para la identificación automática de n-clases en microblogging de redes sociales. Los datos recopilados automáticamente para el estudio están conformados por 190 000 tweets de cuatro organismos oficiales: Metro, Protección Civil, Policía, y Gobierno de México. De los resultados obtenidos, se recomienda el uso de Random Forests, ya que se consigue una precisión media del 81.46 % y una cobertura media del 59.88 %, con nueve tipos de quejas identificadas automáticamente.

Authors: Barros Contreras Ismael , Vargas Olavarría Ángelo , Muñoz Arancibia Fabián
Published: February 2020

En este trabajo, aplicando la teoría de las capacidades dinámicas, testeamos el modelo de ‘dynamic familiness’ en el contexto chileno. Este modelo de familiaridad dinámica ha sido desarrollado recientemente, se fundamenta a partir de la influencia de la familia en la empresa y en sus dos enfoques de análisis – participación y esencia – y su impacto en la generación de rutinas organizativas familiares. En este sentido, el modelo permite estudiar la generación de capacidades dinámicas a partir del proceso idiosincrásico de gestión del conocimiento que se manifiesta en la empresa familiar. De acuerdo con el estado de desarrollo teórico de la literatura que fundamenta el modelo de investigación, se aplica la metodología de estudio de caso a una empresa familiar representativa en el contexto chileno. El estudio proporciona evidencia relevante para contrastar el modelo de investigación en el contexto chileno. Los resultados obtenidos permiten analizar en perspectiva como la influencia familiar impacta en el desarrollo de capacidades, haciendo que la empresa se proyecte a través de las generaciones. Esta investigación permite ampliar la evidencia sobre el alcance de la familiaridad dinámica en el contexto tanto teórico como de gestión de la empresa familiar.

Application of PiCUS® Sonic Tomograph 3 in studies on the cultural heritage of the Lublin region – restoration of the Eastern Orthodox church of the Dormition of the Blessed Virgin Mary in Uhrusk
Authors: Dudkiewicz Margot
Published: February 2020

Uhrusk is a small town located in eastern Poland, in the Lublin region, along the border river, the Bug. The temple is situated on the outskirts of the village, on a low hill, where there was a castle founded by Prince Daniel Halicki in the Middle Ages. The Orthodox church existed here before 1220, and for the first decades of its functioning it had the status of a council. Today, the existing church building was erected in 1849 as a Greek Catholic temple founded by the owner of local estate, Laura Kirsztejnowa. In 1915, the church was abandoned when the Orthodox residents of Uhrusk became refugees. In the years 1920-1927, it was renovated, due to significant losses suffered during the First World War and the Polish-Bolshevik war. The building was open again from 1920 to 1947, after which it was closed following the deportation of Orthodox Ukrainians as part of the “Wisła” Operation. At the end of the 1950s, the Orthodox church was restored for liturgical use as a branch of the parish in Włodawa. The style of the building is defined as classicist-Byzantine with neo-Romanesque and neo-Gothic elements. In 2017, on the initiative of the Dialog Foundation in Lublin, a general renovation of the temple building and its surroundings began. Studies conducted with the use of specialized diagnostic equipment in the form of a Picus 3 sonic tomograph were important for the dendrological inventory. Within the boundaries of the property, 11 trees are growing, at different ages and in a healthy state. On the basis of the material collected, possible directions for the restoration of the Orthodox church’s surroundings were presented.

Hortiterapia jest pojęciem o szerokim spektrum rozumienia. W tym pojęciu mieszczą się działalności związane z pracą w ogrodzie czy twórczością wykorzystującą ogrodowe elementy.
W artykule skupimy się na ogrodach dedykowanym terapii chorób neurodegeneratywnych i psychicznych.
Rozważania o sposobach włączenia chorych w różne aktywności ogrodowe są bogatym źródłem informacji o funkcjonowaniu ogrodów terapeutycznych jednak uwagę zwraca marginalne traktowanie aspektów związanych z projektowaniem.
Metodyka postępowania w projektowaniu ogrodu dla hortiterapii wynika z połączenia zasad projektowania przestrzeni z uwzględnieniem projektowania uniwersalnego oraz celowego stosowania rozwiązań odnoszących się do konkretnych dysfunkcji.
W wyniku przeprowadzonych analiz stwierdzono, że zasady projektowania dla hortiterapii nie są uniwersalne a zróżnicowanie w doborze elementów i ich form jest skorelowane z dysfunkcją.
Projekt ogrodu dla hortiterapii w swej specyfice ukazuje możliwość takiej organizacji przestrzeni, aby stawała się ona miejscem szczególnym, ukierunkowanym na potrzeby chorych wynikające z ich dysfunkcji.

Published: February 2020

This paper presents the influence of varieties and different doses of applied
nitrogen on grain yield and protein content of triticale. The experiment was
set in the period from 2010 to 2012 in the north of Montenegro, in the
vicinity of Bijelo Polje. The research included 5 varieties of winter
triticale (Odyssey, Kg-20, Triumph, Rtanj and Tango) originating from
different breeding houses and the following varieties of fertilization:
control (without fertilization), only nitrogen in the amount of 60 kg ha-1
and nitrogen in the amount of 60 and 90 kg ha-1 in combination with the same
amount of phosphorus and potassium (80 kg ha-1). The results of the study
showed that the lowest average grain yield was obtained in the
non-fertilizing variant - control. The use of fertilizers in all tested
varieties has led to a very significant increase in yield in all variants
compared to control. The Kg-20 variety had the lowest average yield, and the
Tango variety had the highest. The highest average protein content was
achieved in the fertilizer variant where only nitrogen was used in the
amount of 60 kg ha-1. Among the researched varieties, the Triumph variety
had the highest protein content in the grains. The data on the achieved
yields and the content of protein in grains, depending on the variety and
the used doses of fertilizer, indicate the characteristics of individual
varieties and can serve as a criterion for the selection of the most
suitable variety for certain agroecological conditions. This is particularly
important for cattle-oriented farms, where the main priority is to ensure a
sufficient amount of quality food.

Published: February 2020

A 2-year farm trial by employing the nutrient priming technique on common
bean (Sar?k?z) and cowpea (?imal) seeds was performed to assess seed yield
and protein content. Priming: (p1) control, (p2) KH2PO4, (p3) ZnSO4 and (p4)
KH2PO4+ZnSO4, planting date: (d1) 20 May, (d2) 15 June 2015, (d1) 7 May,
(d2) 7 June 2016 were used to study the yield (kg ha-1) and crude protein
(%) of the mentioned crops in Ankara, Turkey. In 2015, application of p3 and
p4 (868.8, 834.8), d2 (962.3) and p4d2, p2d2 and p3d2 (1061, 1052, 1028)
increased seed yield of Sar?k?z, and p2 and p1 (899.5, 835.9) and d2 (955.9)
increased the yield of ?imal. Treatments of p4 and p3 (18.7, 18.5), d2
(19.2), and p4d2 (21.3) increased the protein of Sar?k?z and d2 (19.4)
increased the protein of ?imal. In 2016, p3 (2506), d2 (2516) and p3d2
(3650) increased the yield, and p4 (26.1), d2 (26.8) and p4d2 (28.3)
increased the protein of Sar?k?z. Treatments of p3 (1979.1), d2 (2664.3) and
p3d2 (3310.6) increased the yield, and d1 (24.1) and p3d1 (25.7) increased
the protein of ?imal. Application of Zn and P by seed priming seems to
effectively increase the yield and protein content of these crops.
Autoantibody Reversion: Changing Risk Categories in Multiple-Autoantibody–Positive Individuals
Authors: So Michelle , O’Rourke Colin , Bahnson Henry T. , Greenbaum Carla J. , Speake Cate
Published: February 2020

OBJECTIVE

Most individuals with two or more islet autoantibodies progress to clinical type 1 diabetes. However, in some individuals, autoantibodies are subsequently lost. Here, our objectives were to determine the frequency of autoantibody loss (reversion) in multiple-autoantibody–positive individuals and to determine the association between reversion and progression to clinical disease.

RESEARCH DESIGN AND METHODS

We analyzed multiple-autoantibody–positive individuals participating in TrialNet’s Pathway to Prevention Study for reversion and determined the effect of reversion on progression to clinical disease using a Cox regression analysis.

RESULTS

Of 3,284 multiple-autoantibody–positive subjects, reversion occurred in 134 (4.1%) and was associated with reduced incidence of clinical disease. Reversion occurred more frequently with older age, lower autoantibody titers, and fewer positive autoantibodies.

CONCLUSIONS

Although reversion of multiple-autoantibody positivity is rare, when it occurs, the risk of progressing to clinical disease is reduced. This suggests unknown mechanisms promoting immune remission in some individuals.

THE ELDERLY’S QUALITY of LIFE IN THE PANTI WERDHA AND THE COMMUNITY OF BANDUNG CITY: WHOQOL-BREF and WHOQOL-OLD Indonesian Version
Authors: Nurbasari Nadya Ayudiawati , Gondodiputro Sharon , Dwipa Lazuardhi
Published: February 2020

The inability of families to care for their elderly causes them to place the elderly in the Panti Werdhas. The elderly who move to a Panti Werdha usually have difficulties to adapt the new surroundings that can affect their quality of life. The World Health Organization (WHO) developed instruments to measure quality of life, a multidimensional and cross-cultural approach,  namely WHO Quality of Life-BREF (WHOQOL-BREF) and WHO Quality of Life-OLD (WHOQOL-OLD). Both instruments have been translated into Indonesian language. The aim of the study was to analyze the differences in quality of life between the elderly who live in the Panti Werdhas and in the community. A cross-sectional analytic quantitative study was carried out  from October to November 2019 at 5 Panti Werdhas and 6 public health centers (Puskesmas) in Bandung City, West Java, Indonesia. The total number of respondents in the Panti Werdha and at the Puskesmas as many as 42 respondents. The selection of respondents in the Panti Werdhas used purposive sampling, whereas in the puskesmas used consecutive sampling. The Chi-square or Fisher's Exact test was used to analyze the respondent's characteristics and  the Mann-Whitney test was used to analyze differences in the quality of life.  This study discovered that respondents living in the Panti Werdhas were older, not married/divorced and less educated compared to respondents in the community. The quality of life of the elderly in Panti Werdhas was lower compared to the elderly in the community for all dimensions (p=≤0.05) except the dimensions of death and dying (p=0.741). It can be concluded that there are differences in the quality of life between the elderly who live in Panti Werdhas and in the community  except at the dimensions of death and dying.
Examining cultural planning in Vienna
Authors: Krisch Astrid
Published: February 2020

Culture and planning have often been connected through issues of culture-led urban development and regeneration or cultural and creative industries. However, cultural provision as a form of social infrastructure has rarely been used to understand the institutionalization of culture within planning practices. I claim that how culture is institutionalized through discursive interactions between different agents reveals the importance of culture for planning practices. I exemplify this notion by analysing the discursive institutionalization of culture within strategic planning in Vienna. The results point to a diametral position of the underlying ideas of culture within planning in Vienna: 1) planning for culture, where culture plays an important role for the social functioning of the city, and 2) planning through culture by using culture as a selling point for the city. The paper analyses cultural planning practices in Vienna since the 2000s, thereby contributing to detailed knowledge on the institutionalization of culture and path-dependent developments of culture within urban planning practices. The paper illustrates the use of culture as a form of social infrastructure for rethinking strategic cultural planning in Vienna.
Participation game
Authors: Prilenska Viktorija
Published: February 2020

Civic engagement in decision-making concerning the built environment has become a widely acknowledged practice. Today this is no longer about the dilemma of civic engagement, but rather about the best strategy for the purpose. Games and gamified applications are gaining popularity as efficient tools for civic engagement, which attract and retain participants, as well as foster learning and experimentation. The article presents the case of a role-play urban design game, Participation Game, which was developed in the iterative design process. The initial prototype of the game was transformed from session to session based on the player feedback, collected through questionnaires and debriefings, as well as the analysis of video recordings of game sessions. The overarching goals of the game were, firstly, to familiarise the audience with public hearings of urban design related projects, and, secondly, to find out how the changes in the setup of the game influence the player experience and the outcomes. The findings indicate that game setup limits the opportunities for discussion, and might even steer it towards desirable (for game authors) outcomes.

Published: February 2020

Immobilization of enzymes is a good field of study to extend the life of enzyme and reduce the cost of the chemical processes, such as separation processes. Urease is an important enzyme with medical and industrial applications. The aim of the present study is to prepare an immobilized urease on a strong cation exchange resin (Amberlite IR120 Na) and study its activity and stability. We monitored the release of Na ions in the collected fractions and searching for enzyme in the fractions as indicators of immobilization by ion exchange phenomenon. Sodium is determined by using atomic absorption spectroscopy technique, while the enzyme concentration was tested by Bradford’s method. Immobilized urease activity was evaluated by salicylate-hypochlorite method. The results indicated a complete immobilization of urease enzyme on the resin surface with reserving 92% of the activity of free enzyme. The immobilized urease enzyme on resin showed good stability and it has a 62% of its activity after 154 days of storage at room temperature. It is concluded that a new immobilized urease enzyme system is prepared with good enzyme activity and stability.
ОСОБЕННОСТИ ЕСТЕСТВЕННОГО ВОССТАНОВЛЕНИЯ ЛЕСНЫХ ЭКОСИСТЕМ НА БЫВШИХ СЕЛЬСКОХОЗЯЙСТВЕННЫХ ЗЕМЛЯХ (НА ПРИМЕРЕ ЮЖНОГО АГРОКЛИМАТИЧЕСКОГО РАЙОНА КАРЕЛИИ)

На примере южного агроклиматического района среднетаежной подзоны Карелии показан хронологический сукцессионный ряд восстановления лесных сообществ. Изучен период в 110 лет после забрасывания сенокосов и пашен, представленный 20- 65- 110-летними реперными древостоями. Процесс постагрогенной трансформации нарушенных участков идет в направлении формирования зональных типов экосистем. Для изучаемых условий характерно восстановление хвойных древостоев с постепенным снижением доли лиственных по мере приближения их к предельному возрасту. Показано, что внутри сукцессионного ряда происходит изменение свойств почв. Изменение экофизиологических показателей состояния микробоценоза наиболее выражены в верхнем (0-20 см) слое почв. Переход пахотных почв в залежные земли приводит к накоплению органического углерода в слое 0-10 см, что вызывает усиление дыхательной активности почв и существенное увеличение пула микробного углерода в них. В слое 10-20 см, напротив, содержание углерода микробной биомассы самым высоким было в пахотной почве хроноряда. В целом, отмечено увеличение численности микроорганизмов важнейших эколого-трофических групп в ряду: ельник 110-летний, ельник 65- летний, березняк 20-летний, сенокос-пашня. Функциональная активность микробного сообщества была максимальной в почвах сенокоса и пашни. Показано, что через сто лет со времени выведения земель из сельскохозяйственного использования сформированные на них растительные сообщества становятся физиономически мало отличимыми от лесов, существовавших до освоения территории. Эти изменения могут быть идентифицированы по косвенным признакам. Одним из них является более высокая продуктивность древостоя по сравнению с участками, незатронутыми сельскохозяйственной деятельностью. Полученные данные комплексных исследований можно использовать при диагностике почв, находящихся на разных стадиях постагрогенной трансформации, также они могут быть основой при мониторинге природной среды.

Peneltian ini memberikan perhatian pada peran P2TP2A Kabupaten Malang sebagai lembaga yang dibentuk untuk memberikan perlindungan terhadap kepentingan dan masa depan anak korban kekerasan seksual. Penelitian ini mengambil rumusan masalah Peran P2TP2A Kabupaten Malang dalam memberikan layanan advokasi korban terhadap anak sebagai Korban Kekerasan Seksual, kendala yang dihadapi dan upaya yang dilakukan P2TP2A Kabupaten Malang dalam memberikan layanan advokasi korban terhadap anak sebagai Korban Kekerasan Seksual. Penelitian ini merupakan peneltian hukum normatif dengan menggunakan metode pendekatan perundang-undangan (statute approach) dan pendekatan empiris yang dianalisa secara deskriptif kualitatif.

Berdasarkan hasil penelitian dan pembahasan, dapat diketahui bahwa keberadaan P2TP2A Kabupaten Malang bisa memberikan pengaruh penting guna meminimalisir kasus kekerasan seksual yang terjadi di Kabupaten Malang. Peran P2TP2A Kabupaten Malang dalam memberikan layanan advokasi korban terdiri dari 2 bentuk yakni secara litigasi dan nonlitigasi. Secara litigasi, berjalan baik tetapi belum maksimal dikarenakan belum tersedianya sumber daya manusia yang memadai atau belum mempunyai keahlian di bidang litigasi. Sedangkan secara non litigasi, bentuk pelayanan yang diberikan terdiri dari dampingan psikologi spiritual, konseling dan mediasi. Sejauh ini layanan nonlitigasi sudah sangat baik dan mendapat dukungan dari masyarakat. Adapun bentuk – bentuk hambatan yang dihadapi ialah belum didukungnya sumber dana dan sumber daya manusia yang memadai dan faktor budaya masyarakat yang masih memandang bahwa permasalahan yang menimpa keluarga mereka merupakan masalah internal yang tidak perlu melibatkan orang luar. Upaya untuk mengatasi hambatan telah dilakukan dengan melakukan pendekatan dan koordinasi dengan instansi daerah terkait dan melakukan sosialisasi atau penyuluhan kepada masyarakat.

Melihat kenyataan ini, disarankan kepada pemerintah daerah untuk menjadikan isu perlindungan anak korban kekerasan seksual menjadi prioritas pembangunan yang termasuk didanai oleh APBD dan kepada lembaga P2TP2A Kabupaten Malang dapat lebih mengoptimalkan program – program yang menjadi prioritas kegiatannya.

The mole ratio of an acid base reaction is one of the important values to state the stoichiometric relationship between acids and bases. However, solving acid-base problems based on stoichiometry is still challenging for new chemists.This issue renders the use of a model for predicting the volume of the acid used an exciting endeavour in academia. This work was to study the individual and interactive effects of the titration parameters such as acid concentration, base concentration and the number of the indicator drops on the volume of acid used in the titration process, using methyl orange as an indicator.We also aimed to study the central composite design (CCD) model of response surface methodology (RSM) for experimental design and modelling of the process. The experimental data were analysed using analysis of variance (ANOVA) and fitted to a second-order polynomial equation using multiple regression analysis. The regression analysis showed a good fit of the experimental data to the second-order polynomial model with a coefficient of determination (R2) value of 0.9751 and model F-value of 43.37. The response surface and contour plots were generated from RSM tool for the interactive effects of the studied parameters on the volume of acid used. The developed model was further validated using existing acid-base titration problems from the Senior Secondary Certificate Examination (SSCE) past questions over 30 years. All observations indicated that the developed model was only valid for a monobasic acid.
PHENOL REMOVAL FROM SYNTHETIC WASTEWATER USING BATCH ADSORPTION SCHEME
Authors: Al-Doury Muzher Mahdi Ibrahem , Alwan Maadh Hasan
Published: February 2020

Phenol is one of the most dangerous pollutant of petroleum industry. Thus its removal is very essential. One of the most popular method used to remove phenol is through adsorption by activated carbon. In the present work, batch adsorption experiments are carried out under various operating parameters: pollutant concentration (CO) (10, 30, and 50mg/L), and activated carbon dose (CD) (250-1500mg/1.25L with an increment of 250). All experiments are performed at laboratory temperature (19ºC) and pH of 7 ± 0.1 while a full factorial mode is applied. Many adsorption models are used to fit experimental data and find out adsorption capacity (ADC) which is a widely used term.The results show that phenol can be completely removed and the adsorption capacity depends on the pollutant concentration (CO) and adsorbent dose (CD). The actual adsorption capacity (AADC) is calculated and found to be highly different from adsorption capacity.

Reduce Drilling Risk in HPHT Gas Field Using Innovative Look-Ahead Technology - A Case Study from South China Sea

Published: February 2020

Located in offshore South China Sea, Ledong high-pressure/high-temperature (HPHT) gas field has entered the appraisal phase after the first discovery was announced in 2015. The pressure gradient of the main target zone is close to 2.2 g/cm3 whereas the top formation is approximately 1.8 g/cm3; the sand packages are separated by a variable shale layer thickness. To avoid kicks, mud losses, or other drilling problems, mud weight must be adjusted accordingly to preserve the well integrity. Hence, the main objective for this hole section is to stop drilling above the main target sand and set casing to isolate the formation with different pressure gradient.

An innovative look-ahead technology based on deep electromagnetic measurements was used to predict the formation change ahead of bit in real time to reduce the drilling risk. After review of the technical and geological challenges encountered in this field, this paper will discuss the successful approach taken to detect formation changes using the new technique. After the shale layer above the target sand has been identified in real-time, drilling will stop above the high-pressured sand to set casing. In addition, the authors will also describe the bottom hole assembly (BHA) configuration and measurement selection in the planning phase to ensure the success of this well.

The real-time interpretation of look-ahead measurements enables boundary detection ahead of the bit at distances ranging from 3 to 20 m in this example. The depth of detection depends on the resistivity contrast between formation, layer thickness, presence of laminations, and the transmitter-to-receiver distance. The application of the innovative look-ahead technology has helped to

Reduce the drilling risk by detecting formation change ahead of the bit

Accurately identify casing shoe position to ensure well integrity

Eliminate extra casing string, which will directly increase the well construction cost

Avoid unnecessary operation adjustments and improve drilling efficiency

Clear prediction of the resistivity profile ahead of the bit enables proactive decision making while drilling. This additional information has removed the need to consider the possibilities for different scenarios and the extra circulating time taken to make decisions among stake holders.

The successful implementation of the look-ahead technology and the application in the HPHT well has led to reduction in overall nonproductive time by reducing drilling risk and improving drilling efficiency. This innovative technique changes the real-time decision-making process while delivering a new way to manage drilling risk.
The Development of High-Performance Float Equipment, Industry Standards and Potential Failure Modes and Causes
Authors: Gonzalez David J , Farley Douglas B
Published: February 2020

The history of float equipment began in 1907, with the development by R.C. Baker of a casing shoe that allowed casing to be cemented in wells. Since that time, major changes in cementing techniques and equipment have taken place to address more challenging applications. This paper reviews the progress of float equipment design over the years and discusses the various failure modes that have been encountered and addressed.

As the drilling and casing installation has grown in reach and design, so the level of sophistication of float equipment and operational techniques has developed and inherent problems have been encountered, identified and addressed. The development of the API Specification 10F will enable operators to better understand the design and performance of float equipment and make choices in design that are best suited to the application being planned. It is of vital importance that operators understand the possible failure modes and the choices available in float equipment valve design that are best suited to their application. There is quite often a tendency to underestimate the importance of choosing the right equipment for the application, and this will be addressed in this paper. The authors will also provide a detailed evaluation of the development, design, performance and suitability of the equipment choices that are available. They will review the industry standards that are applicable to float equipment, the various failure modes that can occur, identify the causes and discuss how to anticipate and address them. Navigating the various features associated with seeming simple float equipment can significantly reduce operational cost.
