Tuen Mun–Chek Lap Kok Link: an outstanding subsea tunnel project in Hong Kong
Authors: Schwob Antoine , Cagnat Estelle , Chen Sebastien , Chan Albert W Y , Ng Conrad C W
Published: September 2019

The 4·5 km long northern subsea tunnel section of the new Tuen Mun–Chek Lap Kok Link in Hong Kong had to overcome challenging ground conditions, not least groundwater pressures of over 5 bar. Hard ground meant some 2000 disc cutters on the two 14 m diameter slurry tunnel boring machines needed changing during the drives, initially by professional divers kept in saturation conditions. Two robotic systems were later developed and installed on the tunnelling machines to do the job. Other innovations included pipe-jacking the 41 subsea cross-passages and creating a 500 m long, 43 m deep caterpillar-shaped cofferdam for a cut-and-cover section. This paper presents details of the innovative solutions used and lessons learned.

Authors: Amariles-Mejía Cristina
Published: September 2019

Introducción: la pregunta por las concepciones y prácticas de la educación en el sector solidario de Medellín es una apuesta por escuchar la voz de las personas y las organizaciones que han desarrollado este tipo de procesos. Metodología: esta investigación tiene un enfoque hermenéutico, con el fin de comprender los textos (entrevistas) de personas clave en el sector de la economía social y solidaria en Medellín. Resultados: el artículo está dividido en cuatro partes: la primera, de contextualización del sector solidario en Medellín y de la investigación como tal; la segunda, centrada en las concepciones de educación que resultan del análisis de las entrevistas; la tercera parte está basada en las prácticas de educación solidaria que presentan los entrevistados, generando una tipología de prácticas, dependiendo del enfoque y el lugar fundamental (o no) en el sector de la economía solidaria de Medellín y, finalmente, las conclusiones. Conclusiones: existen dos modos de ver la educación en el sector de la economía solidaria: uno, con relación al fortalecimiento interno del sector y su apuesta educativa para su promoción y consolidación; y dos, la otra mirada en articulación con los movimientos sociales y en una apuesta de transformación de la sociedad.
Ciudad: ¿máscara civilizatoria?
Authors: Segura-Gutiérrez José Miguel
Published: September 2019

Propósito: el artículo reflexiona en torno a la forma en que la ciudad, como expresión inacabada del proceso civilizatorio, al menos en Occidente, ha favorecido no solo la institucionalización de formas socioculturales, políticas y económicas para beneficio de la humanidad, sino que, a su turno, también ha provocado su malestar; tanto por el carácter egoísta que habita en los seres humanos, como por la búsqueda incesante de mejores condiciones de vida. Descripción: se muestra, desde la posición del ciudadano-persona, su fragilidad frente a ciertas formas de administración de la vida humana, que se emplazan desde espacios institucionales para subjetivar al sujeto y revelar de esa forma la compleja y problemática realidad social, subjetiva y cultural de aquellos que la habitan. Punto de vista: es desde la ciudad como espacio social donde es posible advertir las tensiones entre los diferentes individuos que la habitan, frente a las demarcaciones socioespaciales, de tiempo y consumo. Conclusiones: la vida humana que se desarrolla en la ciudad no es más que la teatralización de un proceso civilizatorio que, en su momento, estuvo colmado de buenas intenciones. La experiencia de vivir en la ciudad no solo es racional y económica, sino también sensorial y muy emotiva.

Published: September 2019

Agricultural education based on active learning
(learning by doing) is an essential part of the daily school life which may
promote the acquisition of knowledge and skills related to the ecological and
social dimensions of sustainability. The purpose of this study was to compare
the learning achievements and skills in agricultural practices between students
who learned through the School Agricultural Learning Center (SALC) and those
who learned in the normal classroom. Participants were 150 Thai high school
students in grade 12 recruited by purposive sampling. The study included three
steps: 1) Investigation of basic data for developing the SALC, 2) Establishment
and development of the SALC, and 3) Use of the SALC for learning: Facebook and
Line were employed as the channels for knowledge exchange, communication on
learning activities holding and activities transfer. A posttest-only control
group design was employed. The results revealed that the students who learned
through the SALC exhibited significantly (p < 0.01) higher learning
achievements and skills in agricultural practices than those who learned in the
normal classroom. Our findings suggest that the SALC is pivotal for improving
the students’ learning achievements and skills in agriculture and should be
promoted to become a natural part of sustainable agriculture education.

Abstract This article explores the relationship between the academy and Roma communities and reflects on how horizontal violence, commodification and scientism have created disconnection and forms of institutional racism. The article reflects upon the emergence of a new cadre of critical Roma researchers challenging the established hierarchies of the academy.   The paper will assess the strength and validity of these challenges and reflect on whether merely new power elites are being formed or whether critical approaches to Romani Studies presents scope for transformative change.
Bringing Gender In? EU Foreign and Security Policy after Brexit
Authors: Haastrup Toni , Wright Katharine A. M. , Guerrina Roberta
Published: September 2019

In this article, we identify Brexit as a critical juncture, wherein the EU has had the opportunity to reflect on and reinforce its identity, as a promoter of gender issues within the security domain. It draws on this identity from a foundational myth of the EU as gender equality polity, resulting in the creation of a socio-legal order and sustained discourse on gender inclusivity in all policy areas. Existing scholarship has drawn attention to the EU’s particular success in gender equality promotion in the areas of social inclusion at member state level, including in the UK. But, is the EU’s reach comprehensive beyond this policy sphere? We examine the ways in which gender is manifested in the area of foreign policy, an area where the UK has consistently shown some leadership on the integration of gender perspectives in its foreign policy through its international development programmes and the implementation of the Women, Peace and Security agenda. It is therefore timely to consider what impact Brexit has on EU policies, practices and the promotion of gender equality in this policy domain. Using a critical feminist lens, this article looks at the evolution of gender equality as a dimension of EU foreign and security policy in the context of EU–UK relations, and the divergences, opportunities and constraints that are crystallised by the Brexit process.
Yüksek riskli gebelerde psikolojik sağlamlık, algılanan stres ve psikososyal sağlık
Authors: ÜZAR ÖZÇETİN Yeter Sinem , ERKAN Mehtap
Published: September 2019

Amaç: Bu çalışmada yüksek riskli gebelerde psikolojik sağlamlık, algılanan stres ve psikososyal sağlık düzeyleri ve ilişkili değişkenlerin değerlendirilmesi amaçlanmıştır.Gereç ve Yöntem: Tanımlayıcı araştırma deseni kullanılan bu araştırmanın örneklemini 54 yüksek riskli gebe oluşturmuştur. Veriler ‘Connor-Davidson Psikolojik Sağlamlık Ölçeği’, ‘Algılanan Stres Ölçeği’ ve ‘Gebelerde Psikososyal Sağlığı Değerlendirme Ölçeği’ ile toplanmıştır. Bulgular: Bulgular değerlendirildiğinde hastane yatış deneyimi olan gebelerin kaygı ve stres düzeylerinin, psikososyal destek gereksinimlerinin, algılanan stres düzeylerinin yüksek olduğu belirlenmiştir. Benzer şekilde yatak istirahati gereksinimi duyan gebelerin stres rahatsızlık algısı, psikososyal destek gereksinimi daha yüksektir. Eğitim düzeyi düşük olan gebelerin algılanan stres düzeyleri daha fazladır. Düzenli gebelik takibi yaptıran gebelerin özyeterlik algısı daha düşüktür ve kaygı ve stres puanları daha yüksektir. Çalışan gebelerin negatif olaylara tolerans düzeyleri daha yüksek çıkmıştır.Sonuç: Yüksek riskli gebelik, algılanan stres düzeyinin artması, psikolojik sağlamlık ve psikososyal sağlık düzeylerinin yüksek olması ile doğrudan ilişkili olabilmektedir. Gebeliği süresince hastane yatışı deneyimleyenlerin algılanan stres düzeylerinin yüksek olması, hastaneye yatışın bireylerin mevcut stres düzeyini artırmasına bağlı olabilir. Bu gebelerin psikososyal sağlık düzeyleri yüksek olsa dahi, algılanan stresi azaltmada yetersiz kalmıştır. Sonuç olarak yüksek riskli gebelerin psikolojik sağlamlık düzeylerinin desteklenmesinin ve geliştirilmesinin gebelerin bu süreci daha kolay ve sağlıklı atlatmalarında önemli bir unsur olduğu söylenebilir.

A flexible upgrade path for the Australian National Broadband Network
Authors: A. Gregory Mark
Published: September 2019

This paper provides a flexible upgrade path for the Australian National Broadband Network (NBN), if the new government decides to alter the construction methodology to include a copper-based access system such as Fibre to the Node (FTTN). The approach described in this paper utilises fibre past premises to provide a transmission media for a Gigabit-capable Passive Optical Network (GPON).  GPON to FTTN devices would be situated in pits adjacent to premises and utilise copper tails to provide a VDSL2 Internet connection to premises. The approach provides a flexible upgrade path for customers to move from their copper based access system to a Fibre to the Home (FTTH) system utilising the relatively future-proof GPON.

Affordable retail pricing on the NBN
Authors: JTDE Editor
Published: September 2019

The National Broadband Network (NBN) has the potential to transform economic and social relations. But realising that potential requires universal take-up and significant utilisation of the NBN. This paper examines how NBN wholesale pricing can help to do this. It introduces a mark-up concept to build a bridge between wholesale and retail prices, provides a yard-stick for how we might define affordable retail pricing and suggests how an entry level wholesale price can be specified to deliver that and enable low income customers to access the NBN.
References to Iconic Landscapes in the Debate Surrounding the Founding of Finland’s National Parks, circa 1880–1910
Authors: Niemelä Juho , Ruuskanen Esa
Published: September 2019

This article reviews the formation of the idea of national parks in Finland between the 1880s and 1910s. It argues that both the term and the concept of national park evolved in a long-lasting deliberative process between competing definitions. The main actors in this process were geographers, forestry scientists and NGOs devoted to popular education and the promotion of tourism. As a result of the debates, iconic landscapes and species were located in Finnish nature inside the wholly artificial boundaries of the national parks. Eventually, both the science and tourism poles of the decades-long debate were incorporated into the plans and visions for Finland’s national parks in the early twentieth century. The national park debate between the 1880s and 1910s focused mainly on landscapes, land formations and vegetation zones, and not so much on the wildlife or indeed the people who lived inside these areas.
Pretreatment of Food Industry Wastewater by Coagulation: Process Modeling and Optimization
Authors: YAZICI GÜVENÇ Senem , CAN GÜVEN Emine
Published: September 2019

In this study, coagulation processes using FeCl36H2O and Al2(SO4)318H2O as coagulants were employed and designed for chemical oxygen demand (COD) and total suspended solids (TSS) removal from food industry wastewater via response surface methodology (RSM). RSM was used for the optimization of coagulation processes and evaluation of the effects and interactions between process variables (pH, coagulant dosage and reaction time). ANOVA was used to analyze the experimental data obtained in the study and secondary regression models were developed by using Statgraphics Centurion XVI.I software. The optimum conditions were pH 9, dosage 1500 mg/L and time 25 min for maximum COD removal efficiency for FeCl36H2O and pH 9, dosage 1493 mg/L and time 25 min for Al2(SO4)318H2O. Under optimum conditions, COD and TSS removal efficiencies were 46.4% and 96.7% for FeCl36H2O and 31.2% and 96.2% for Al2(SO4)318H2O, respectively. ANOVA results showed that the responses of model have high coefficient values (R2 > 0.80), and hence the second order regression model can be explained with these experimental data. The proposed model fits very well with the experimental data with R2 of 0.9677 for COD and 0.9543 for TSS removal for FeCl36H2O and 0.9456 for COD and 0.9260 for TSS removal for Al2(SO4)318H2O, respectively. Model results showed that the RSM for coagulation processes using both coagulants is a powerful tool for optimizing the experimental conditions. Moreover, it can be concluded that both coagulation processes may be an effective alternative pre-treatment process for food industry wastewater.

Published: September 2019

Este artigo identifica alguns acontecimentos marcantes na cidade de Belém-Pará, os quais influenciaram na produção e reconfiguração de Espaços Públicos, em especial na conformação dos largos que, atualmente, são mais conhecidos pela denominação de Praças Públicas. Para tanto, utilizou-se de ampla pesquisa bibliográfica e documental sobre a fundação e expansão urbana da cidade de Belém. Os resultados apontaram que, por aproximadamente dois séculos, a institucionalização desses espaços esteve vinculada a interesses religiosos de consolidação do catolicismo, por favorecer a aglutinação de pessoas. Somente no final do século XIX, foram denominados de praças e passaram a servir, mais fortemente, às práticas de lazer e de sociabilidade na cidade.

Authors: Leal Leal Avigo Eric , F. Stodden David , A. R. Silva Ayrton , B. Rodrigues Vinicius , A. Barela José
Published: September 2019

BACKGROUND: Previous studies have confirmed that there is a developmental delay in the fundamental motor skills (FMS) of Brazilian children based on various samples. However, none of these previous studies included a comprehensive and direct diagnosis of motor competence levels of children in the urban areas of Brazil, which tend to encompass a wide range of socioeconomic and cultural environments. AIM: The purpose of this study was to directly assess children’s FMS competence levels in the city of São Paulo, Brazil. METHOD: Three hundred and eighty-three children (ages 6, 8, and 10) from elementary schools in all five geographic regions of São Paulo participated in this study. The FMS of children were assessed using the Test of Gross Motor Development-Second Edition. RESULTS: The results indicated that children from all five geographic areas of São Paulo demonstrated low competence levels (below the 15th percentile) across all FMS. Moreover, the observed motor competence deficit increased with age. Children’s competence levels were classified as poor in 6-year-old children and very poor in 8- and 10-year-old children. CONCLUSION: The developmental delay in motor competence is associated with decreased levels of health-enhancing physical activity, physical fitness, executive function, and perceived competence and increased obesity.

Authors: Momose Akishi , Yabe Michihiko , Chiba Shigetoshi , Kumakawa Kenjirou , Shiraiwa Yasuo , Mizukami Hiroki
Published: September 2019

Background: We investigated ion channels at the skin, including peripheral nerve endings, which serve as output machines and molecular integrators of many pruritic inputs mainly received by multiple G protein-coupled receptors (GPCRs). Methods: Based on the level of chronic kidney disease–associated pruritus (CKD-aP), subjects were divided into two groups: non-CKD-aP (no or slight pruritus; n=12) and CKD-aP (mild, moderate, or severe pruritus; n=11). Skin samples were obtained from the forearm or elbow during operations on arteriovenous fistulas. We measured ion channels expressed at the skin, including peripheral nerve endings by RT-PCR: Nav1.8, Kv1.4, Cav2.2, Cav3.2, BKCa, Anoctamin1, TRPV1, TRPA1, and ASIC. Results: Expression of Cav3.2, BKCa, and anoctamin1 was significantly elevated in patients with CKD-aP. On the other hand, expression of TRPV1 was significantly reduced in these patients. We observed no significant difference in the levels of Cav2.2 or ASIC between subjects with and without CKD-aP. TRPA1, Nav1.8，and Kv1.4 were not expressed. Conclusions: It was concluded that this greater difference in expression of ion channels at the skin tissue including specific for cutaneous peripheral nerve endings in CKD patients with CKD-aP may increase generator potential related to itching.

Abstract: Current models in design of urban water management systems and their corresponding infrastructure using centralized designs have commonly failed from the perspective of cost effectiveness and inability to adapt to the future changes. These challenges are driving cities towards using decentralized systems. While there is great consensus on the benefits of decentralization; currently no methods exist which guide decision-makers to define the optimal boundaries of decentralized water systems. A new clustering methodology and tool to decentralize water supply systems (WSS) into small and adaptable units is presented. The tool includes two major components: (i) minimization of the distance from source to consumer by assigning demand to the closest water source, and (ii) maximization of the intra-cluster homogeneity by defining the cluster boundaries such that the variation in population density, land use, socio-economic level, and topography within the cluster is minimized. The methodology and tool are applied to Arua Town in Uganda. Four random cluster scenarios and a centralized system were created and compared with the optimal clustered WSS. It was observed that the operational cost of the four cluster scenarios is up to 13.9 % higher than the optimal, and the centralized system is 26.6% higher than the optimal clustered WSS, consequently verifying the efficacy of the proposed method to determine an optimal cluster boundary for WSS. In addition, optimal homogeneous clusters improve efficiency by encouraging reuse of wastewater and stormwater within a cluster and by minimizing leakage through reduced pressure variations.

Objectives. Vertebrobasilar dolichoectasia (VBD), an elongation and distension of vertebrobasilar artery, may present with cranial nerve symptoms due to nerve root compression. The objectives of this study are to summarize vestibulocochlear manifestations in subjects with VBD through a case series and to discuss the needs of thorough oto-neurotologic evaluation in VBD subjects before selecting treatment modalities.Methods. Four VBD subjects with vestibulocochlear manifestations were reviewed retrospectively. VBD was confirmed by either brain or internal auditory canal magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA). Patient information, medical history, MRI/MRA findings, and audiometry or vestibular function tests were reviewed according to patient’s specific symptom.Results. Of the four subjects, three presented with ipsilesional sensorineural hearing loss (SNHL), three with paroxysmal recurrent vertigo, and two with typewriter tinnitus. The MRI/MRA of the four subjects revealed unilateral VBD with neurovascular compression of cisternal segment or the brainstem causing displacement, angulation, or deformity of the cranial nerve VII or VIII that corresponded to the symptoms.Conclusion. Vestibulocochlear symptoms such as SNHL, recurrent paroxysmal vertigo, or typewriter tinnitus can be precipitated from a neurovascular compression of the vestibulocochlear nerve by VBD. Because proper medical or surgical treatments may stop the disease progression or improve audio-vestibular symptoms in subjects with VBD, a high index of suspicion and meticulous radiologic evaluation are needed when vestibulocochlear symptoms are not otherwise explainable, and if VBD is confirmed to cause audiovestibular manifestation, a thorough oto-neurotologic evaluation should be performed before initial treatment.
Ipsilateral Posterior Cruciate Ligament Insertion Avulsion and Femoral Head Fracture Without Dislocation: A Rarest of Rare Dashboard Injury and Principles of Management
Authors: Kumar Prasoon , Agarwal Saurabh , Rajnish Rajesh Kumar , Aggarwal Sameer , Kumar Vishal , Jindal Karan
Published: September 2019

Case:

A 25-year-old man presented with posterior cruciate ligament (PCL) avulsion and ipsilateral fracture of the femoral head after sustaining a dashboard injury. The hip was not dislocated on presentation, and there were no other injuries; he was managed operatively for both. His hip and knee healed well, with good functioning at 15 months of follow-up.

Conclusions:

Dashboard injuries can cause simultaneous knee and hip injuries, usually PCL and posterior hip dislocation. This case report identifies a specific pattern of tibial avulsion fracture of the PCL combined with femoral head fracture with no dislocation at presentation. The good outcome achieved at 15 months indicates that standard treatment of open reduction and internal fixation for both fractures can provide good clinical results in this severe combination injury pattern.

Authors: Aya Kessiena L. , Carmichael Kelly D. , Igbinigie Matthew
Published: September 2019

Case:

We present an unusual case of a distal metaphyseal femur insufficiency fracture in an adolescent with a history of multiple low-energy appendicular fractures. A genetic workup was significant for a variant of unknown significance to the Col1A1 gene.

Conclusions:

To our knowledge, this is the first report of this collagen gene variant as a risk factor for multiple fractures. The case illustrates the presentation of this gene’s phenotype and suggested medical management.

Authors: Samade Richard , Jones Grant L. , Bishop Julie Y.
Published: September 2019

Case:

A 66-year-old man presented with 2 years of atraumatic right shoulder pain and difficulty with overhead activities. Radiographs and magnetic resonance imaging demonstrated Hamada stage I changes and a massive irreparable rotator cuff tear involving the supraspinatus and infraspinatus. He underwent superior capsular reconstruction with acellular human dermal matrix (SCR with ADM) allograft. Diagnostic arthroscopy and humeral avulsion of the glenohumeral ligament repair 1 year postoperatively showed that the SCR appeared intact and vascularized.

Conclusions:

This is the first study to confirm visually that SCR with ADM allograft is well-vascularized and intact 1 year post-operatively.

Published: September 2019

Case:

A 65-year-old man previously treated by intramedullary nailing for a left tibial shaft fracture presented 6 years later with an open refracture of his left tibia after a motorcycle accident. Treatment required extraction of the bent nail before revision nailing.

Conclusions:

Extraction of deformed intramedullary devices is a skill that will continue to be demanded of orthopaedic surgeons. In this case, standard extraction though the entry point proved successful. Standard extraction offers the safest form of removal and should be contemplated before considering more morbid methods of extraction while examining the fracture's morphology and the device's deformity.

Published: September 2019

Background:

Good long-term outcomes have been reported for the Salter innominate osteotomy (SIO), which is widely used to correct developmental dysplasia of the hip (DDH) in children. In this study, we describe the procedure and early outcomes of a new pelvic osteotomy termed “angulated innominate osteotomy” (AIO).

Methods:

Twenty-one patients (22 hips) underwent AIO. We evaluated age at the time of surgery, operative time, blood loss, and time to bone union. Several radiographic parameters were assessed preoperatively, immediately postoperatively, and at the time of the latest examination. Measurements were compared with those of 20 previous patients who underwent SIO. The AIO is made to form an isosceles triangle. This enables 2 points of contact between the proximal and distal bone fragments, eliminating the need for a bone graft.

Results:

Mean age at the time of surgery was 5.9 years, and the mean duration of follow-up was 30.8 months. The mean operative time was 103 minutes, mean blood loss was 33 mL, and mean time to bone union was 9.8 weeks. Immediately postoperatively, the mean “distance d” (lateral displacement of the distal fragment), mean ratio of the obturator heights (ROH), and mean lateral rotation angle (LRA) were 7.2 mm, 70.4%, and 19.3°, respectively. At the latest examination, the mean acetabular index (AI), center-edge angle (CEA), and acetabular head index (AHI) were 16.4°, 23.7°, and 85.5%, respectively, each of which were significantly improved compared with the preoperative values. Moreover, the mean postoperative iliac length difference (ILD) between the operative and contralateral sides was only 0.1 mm. Those treated with AIO had a significantly shorter operative time and time to bone union, and less blood loss, than those treated with SIO. The mean distance d, ROH, and LRA did not differ significantly from SIO results, while the mean ILD was significantly less.

Conclusions:

AIO is a less-invasive procedure that does not require a bone graft, and the short-term outcomes were favorable. Sufficient coverage of the acetabulum with displacement of the distal bone fragment to an extent similar to SIO can be achieved; we consider AIO a worthy surgical procedure that has the potential to provide good long-term outcomes similar to those seen with SIO.

Objectives: Dramatic increases in opioid and drug overdose mortality have occurred in the United States (US) over the past two decades. To address this national public health crisis and identify gaps in the literature, we analyzed recent empirical trends in US drug overdose mortality by key social determinants and conducted a selective review of the recent literature on the magnitude of the opioid crisis facing different racial/ethnic, socioeconomic, and rural-urban segments of the US population.

Methods: We used the 1999-2017 mortality data from the US National Vital Statistics System to analyze trends in drug overdose mortality by race/ethnicity, age, and geographic area. Log-linear regression was used to model mortality trends. Using various key words and their combinations, we searched PubMed and Google Scholar for select peerreviewed journal articles and government reports published on the opioid epidemic between 2010 and 2018.

Results: Our original analysis and review indicate marked increases in drug overdose mortality overall and by race/ethnicity and geographic regions, with adolescents and young adults experiencing steep increases in mortality between 1999 and 2017. Our selective search yielded 405 articles, of which 39 publications were selected for detailed review. Suicide mortality from drug overdose among teens aged 12-19 increased consistently between 2009 and 2017, particularly among teen girls. The rise of efficient global supply chains has increased opioid prescription use and undoubtedly contributed to the opioid epidemic. Many other important contributing factors to the epidemic include lack of education and economic opportunities, poor working conditions, and low social capital in disadvantaged communities.

Conclusions and Global Health Implications: Our analysis and review indicate substantial disparities in drug overdoses and related mortality, pain management, and treatment outcomes according to social determinants. Increases in drug overdoses and resultant mortality are not only unique to the US, but have also been observed in other industrialized countries. Healthcare systems, community leaders, and policymakers addressing the opioidepidemic should focus on upstream structural factors including education, economic opportunity, social cohesion, racial/ethnic disadvantage, geographic isolation, and life satisfaction.

Slimhole Unconventional Well-Design Optimization Enables Drilling Performance Improvement and Cost Reduction
Authors: Schumacker Eric , Volgelsberg Philip
Published: September 2019

Slimhole well design can reduce well–construction cost through a reduction in steel, fluids, and disposal costs. In the industry, there has been a misconception that slimhole size involves the tradeoff of slower rate of penetration (ROP) and less–efficient fracture treatment. Improvements in downhole tools, drillstrings, rig capability, and drilling–fluid design have been implemented to improve ROP in slimholes. Completion designs were refined for slimmer holes to avoid any significant loss in stimulation effectiveness and maintain well value. Through systematic replication of learnings and designs across basins, slimhole well design has advanced. Slimhole well design (transition from 8.5/7.875–in. hole and 5.5–in. production casing to 6.75/6.25–in. hole and 5.5/4.5–in. production casing) can reduce unconventional well cost, which reduces well unit-development cost (UDC).
