A escrita epistolográfica de Clarice Lispector e a importância do gênero epistolar para os estudos literários
Authors: Silva Luciana Aparecida
Published: April 2018

Clarice Lispector residiu muitos anos no exterior, em diversos países: Suíça, Estados Unidos, Itália e Inglaterra, em razão do casamento com o diplomata brasileiro Maury Gurgel Valente. Por esse motivo, utilizou as missivas como a principal forma de manter contato com amigos e familiares e para tratar dos mais variados assuntos. As correspondências da autora estão publicadas em três livros: Cartas perto do coração (2000) - engloba as cartas trocadas entre a autora e o escritor Fernando Sabino; Correspondências (2002) - cujos interlocutores eram familiares, amigos, intelectuais, artistas e escritores; e Minhas queridas (2007), obra que reúne a vasta correspondência entre as irmãs Tania, Elisa e Clarice Lispector. Nas missivas trocadas entre a autora e seus interlocutores são tratados os mais diversos assuntos: momentos banais do cotidiano, literatura, arte, política, etc. Além disso, podemos notar que Lispector deixa transparecer aspectos que nos auxiliam na tentativa de desvendar a subjetividade da intrigante escritora que desempenhou vários papéis (mãe, mulher, escritora, amiga, irmã, etc) e utilizou várias "máscaras" ao longo da vida, pois "Escolher a própria máscara é o primeiro gesto voluntário humano. E solitário”.
NARRATIVAS CINEMATOGRÁFICAS E IDEOLOGIAS DA CONTEMPORANEIDADE: A EVOLUÇÃO DO FEMININO EM PRODUÇÕES INFANTIS
Authors: Santos Fernanda Oliveira , Barbosa Carrijo Silvana Augusta
Published: April 2018

Neste artigo pretendemos investigar de que forma os filmes Valente (2012), Frozen (2013) e Malévola (2014) concorrem para a formação de novas ideologias no que tange à reconfiguração do feminino examinando o processo de representação identitária das princesas nas narrativas em questão. Observaremos como a arte literária, interligada à arte do cinema, tem se relacionado com a construção da identidade do sujeito, contribuindo para a formação tanto individual quanto coletiva na contemporaneidade. Nos utilizaremos de contribuições advindas de estudos acerca da teoria do cinema, da literatura infantil, dentre outras, para a constituição do instrumental teórico a que recorreremos para compreender a relação da arte literária com a arte cinematográfica.
BOJUNGA – POR UMA LEITURA ESTÉTICA
Authors: Souza Dalma Flávia Barros Guimarães de , Leão Cleonice De Moraes Evangelista
Published: April 2018

Este artigo tem o objetivo de apresentar práticas alternativas que valorizem a qualidade artística de obras literárias e favoreça uma leitura estética, através da metodologia de diários de leitura e fichas de função. Para tanto discutimos alguns temas que se relacionam com os interesses da pesquisa, quais sejam: letramento literário, círculos de leitura, leitura literária com qualidade estética. Fizemos algumas considerações sobre a leitura de obras da autora Lygia Bojunga e sua eficácia para o círculo de leitura literária que sugerimos. Assim como Cosson (2014), acreditamos que os círculos de leitura é uma ótima estratégia, pois promove o hábito de ler, a formação do leitor e a leitura literária, deste modo, possui amplitude que vai além da escola, valorizando o letramento literário e a escolarização adequada da literatura.
PELO AVESSO DA BELEZA CONSAGRADA: ESCRITA E DESCONSTRUÇÃO EM A MULHER QUE ESCREVEU A BÍBLIA
Authors: Sousa de Menezes Alana Regina , Enedino Wagner Corsino
Published: April 2018

Este artigo tem como objetivo apresentar a obra A mulher que escreveu a Bíblia (1999), de Moacyr Scliar, sob uma perspectiva metodológica que associa o ato da escrita à desconstrução de olhares e de perspectivas; pensa ainda a respeito dos conceitos de feiura e do espaço ocupado pela representação do feminino na literatura. Para ancorar o percurso analítico, faz-se uso dos estudos de Umberto Eco (2007), no que tange aos elementos trazidos pela estética do feio; dos postulados de Theodor Adorno (2009), para melhor visualização dos aspectos filosóficos aliados à desconstrução do sujeito; bem como das ideias de Jonathan Culler (1999) e Autran Dourado (1973) para um panorama mais específico acerca de literatura e personagem. A obra reflete sobre o ato da escrita como um veículo de poder, desnudando uma personagem que é a metáfora do sujeito feminino pensado pela contemporaneidade.

Published: April 2018

RESUMO                                                                                                                   Este artigo pretende analisar o tratamento linguístico-discursivo conferido às informações sobre o Fim do Mundo referentes a uma reportagem publicada na revista Superinteressante, edição especial de novembro de 2012, durante a polêmica suscitada pelo Calendário Maia. Para isso, buscou-se descrever e analisar como ocorre o processo de recontextualização do conhecimento científico em textos de divulgação científica por meio dos procedimentos linguístico-discursivos de expansão, redução e variação e das estratégias divulgativas. Ao final da análise, chegou-se à conclusão de que a situação de comunicação é norteadora do discurso veiculado na reportagem. Verificou-se também que foram utilizadas várias estratégias divulgativas direcionadas para um público jovem. Percebeu-se que a revista informa e, como estratégia discursiva, deixa o leitor curioso e motivado em ler sobre o assunto em questão. O procedimento linguístico-discursivo mais recorrente na reportagem foi a expansão e a estratégia divulgativa mais utilizada foi a explicação.         PALAVRAS-CHAVE: Recontextualização; Procedimento linguístico-discursivo; Estratégia divulgativa.
CONECTANDO MULTISSEMIOSES E TECNOLOGIAS DIGITAIS À PRÁTICA DE ENSINO DE LÍNGUA PORTUGUESA
Authors: E Silva Gilda Das Graças , Ottoni Maria Aparecida Resende
Published: April 2018

Partindo da relevância de um ensino de Língua Portuguesa voltado para as práticas sociais de uso da linguagem, apresentamos, neste artigo, um protótipo de leitura e análise crítica e de produção de textos multissemióticos em conformidade com os Parâmetros Curriculares Nacionais (PCN) para o Ensino Fundamental. Baseamo-nos na Análise de Discurso Crítica (ADC) proposta por Fairclough (2003), na proposta da pedagogia de multiletramentos (ROJO, 2012, 2015; COPE; KALANTZIS, 2006, 2008) e nos letramentos digitais (DUDENEY; HOCKLY; PEGRUM, 2016). Esse protótipo prioriza o ensino de gêneros discursivos digitais do cotidiano do aluno, compartilhados em redes sociais e em aplicativos. Tal escolha deve-se ao fato de vivermos na era das linguagens fluidas - era digital, na qual nos deparamos com a necessidade de estratégias que correspondam com as demandas atuais do ensino e com as dos alunos. Dessa forma, destacamos que a escola é o espaço ideal para desenvolvimento dessas habilidades, para a promoção da autonomia e para o fortalecimento identitário do aluno.

Tereny zieleni w gminie miejsko-wiejskiej Stryków i ich wpływ na jakość życia mieszkańców
Authors: Pielesiak Iwona
Published: April 2018

W artykule zwrócono uwagę na tereny zieleni w gminie miejsko-wiejskiej na przykładzie gminy Stryków. W pierwszej części opracowania omówiono strukturę rodzajową i rozmieszczenie terenów zieleni, nawiązując do wybranych zagadnień współczesnego rozwoju społeczno-ekonomicznego omawianej jednostki. W dalszej kolejności przedstawiono wyniki wywiadu kwestionariuszowego z 490 mieszkańcami gminy. Omówiono percepcję lokalnych terenów zieleni oraz postrzeganie ich związku z jakością życia w gminie Stryków. Z badań wynika, że respondenci doceniają gminne tereny zieleni, zwłaszcza te, które poprzez bogate zagospodarowanie są dobrze przystosowane do pełnienia funkcji rekreacyjno­-wypoczynkowych. W wywiadach akcentowano także rolę zieleni w kształtowaniu krajobrazu gminy oraz poprawie lokalnych warunków zamieszkania. Jest to o tyle istotne, że badana jednostka terytorialna cechuje się dynamicznym rozwojem społeczno-ekonomicznym i silną ekspansją obiektów budowlanych, w tym wielkopowierzchniowych hal produkcyjnych i magazynowych oraz obiektów infrastruktury technicznej na tereny otwarte. Zjawiska te mogą w efekcie pogorszyć walory gminnego krajobrazu, a przez to – negatywnie wpłynąć na jakość i chęć mieszkania w gminie Stryków.

Significance of weather forecasting on oilseeds crop production in India: A-review
Authors: Meena H. M. , Jadon K. S. , Singh D. V.
Published: April 2018

Oilseed production in India is on cross-roads and has major dependency on the imports. The majority of oilseeds were introduced in India since ages and well-adopted by the farmers. Like other crops oilseed production also invariably depends on weather variables as major oilseeds are grown in rainfed situation. Therefore, an accurate weather forecast for the sowing time, growing season and pest-disease situation is need of hour to overcome the weather vagaries. In this review we have tried to mention important environment factors which affect oilseed production vis-a-vis disease situation in the oilseed crops and to measure the changing scenario.
Comparison of anterior segment parameters between pediatric and adult keratoconus groups
Authors: TOPRAK İbrahim , YILDIRIM Cem , YAYLALI Volkan
Published: April 2018

Aim: To determine differences in anterior segment measurements between pediatric and adult keratoconus groups using Scheimpflug imaging system.Materials and Methods: This retrospective study included 133 patients with keratoconus and 101 healthy controls. Subjects were grouped as pediatric and adult. Differences in anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), pachymetry, corneal volume (CV) and maximum keratometry (Kmax) were sought between the age-based subgroups.Results: Right eyes of the 133 keratoconus patients (56 pediatrics and 77 adults) and 101 healthy controls (41 pediatrics and 60 adults) were reviewed. Pediatric subgroups had significantly higher ACD and ACV compared to those of the adult subgroups in both groups (p<0.05). On the other hand, pediatric and adult keratoconus patients had significantly higher ACD than in the age (subgroup) matched controls (p< 0.05). In the pediatric keratoconus subgroup, eyes with stage 3 keratoconus had significantly deeper ACD than in the eyes with stage 2 keratoconus (p<0.05). However, in the adult group, only corneal parameters were significantly lower in eyes with stage 3 keratoconus compared to those of the eyes with stage 2 keratoconus (p<0.05).Conclusion: Anterior chamber measurements appear to be altered by aging in both keratoconus and control groups, whereas eyes with keratoconus in all age subgroups appear to have a deeper AC than in the age-matched normals. Moreover, an increase in ACD in pediatric keratoconus might be indicative of progression. However, in the adult keratoconus, corneal parameters appear to decrease with keratoconus progression.

Authors: KORKMAZ Özgür , MALKOÇ Melih , GÜRCAN Serkan
Published: April 2018

Aim: The aim of this study is to evaluate the anterior cruciate ligament (ACL) tears in Turkish office workers on the artificial playing surfaces.Materials and Methods: Eighty-seven patients who were operated for anterior cruciate ligament tear that had injuries on artificial surfaced playing areas (ASPA)s were evaluated retrospectively. Evaluations were undertaken using Lysholm and Tegner Activity Scale pre-operatively and in the last follow-up. Injury mechanisms, shoe types, frequency of sporting activity, time of warm-up exercises before sporting activity were assessed. Types of ASPA’s, body mass index (BMI) and return to work period were also determined.Results: Increase in Lysholm and Tegner activity scale between the preoperative and postoperative scores was found to be statistically significant (p<0.001). ACL tear occurred with non-contact injury in 65 patients, 22 patients had ACL tear with direct contact trauma. Football activity on the ASPAs is social allocation rather than a sportive activity. The rate of wearing special designed shoes for ASPA in sporting activities was low. The mean frequency of sporting activity was 1.4 times/month and the mean warm-up exercise time was 6.42 minutes. Sixty-nine ASPAs were made with 3th generation turf, 18 were 2nd generation turf. The mean BMI was 23.32 kg/m². The mean period for return to work was 17.41 weeks.Conclusion: Irregular sportive activity with insufficient equipment on the ASPA causes serious ACL injuries that have to be managed by surgical procedures with loss of working time and economical casualties.

Bone mineral density in obese children with prediabetes
Authors: ÜSTYOL Ala , ATABEK Mehmet Emre
Published: April 2018

Aim: The
aim of this study was to evaluate the relationships between bone mineral
density (BMD) vs metabolic risk factors in obese adolescents with
prediabetes. Materials and Methods: A total of 131 obese children and adolescents, aged 6-18 years of age
were enrolled the study. Prediabetes was determined by a fasting blood glucose
level of ≥100 to 125 mg/dL or 2-hour oral glucose tolerance test value of ≥140
to 199 mg/dL. Five patients who were diagnosed as having type 2 diabetes were
excluded and remaining participants were classified as normal glucose tolerance
(NGT) and prediabetic. BMD was measured on calcaneus using quantitative
ultrasound. BMD and metabolic parameters were investigated and compared in
these two groups.

Results: There
was no significant difference in BMD between children and adolescents with
prediabetes (n = 37) or NGT (n = 89). The parameters of prediabetes did not
affect BMD and these results did not change when we adjusted for weight,
height, age, sex, pubertal status. The multivariate linear regression analysis
revealed that the only independent factor associated with higher BMD was higher
BMI (OR=0.007 95%CI 0.002-0.013 p=0.013). No significant associations were
found between BMD and waist circumference or biochemical measurements.Conclusion: Plasma glucose within the
prediabetic range is not associated with bone mineral density in obese
children. Thus, the positive association of BMI with BMD may be by means of
alternative pathways.

Topological Information Data Analysis: Poincare-Shannon Machine and Statistical Physic of Finite Heterogeneous Systems
Authors: Baudot Pierre , Tapia Monica , Goaillard Jean-Marc
Published: April 2018

This paper establishes methods that quantify the structure of statistical interactions within a given data set using the characterization of information theory in cohomology by finite methods, and provides their expression in terms of statistical physic and machine learning. Following [1–3], we show directly that k multivariate mutual-informations (Ik) are k-coboundaries. The k-cocycles are given by Ik = 0, which generalize statistical independence to arbitrary dimension k. The topological approach allows to investigate Shannon’s information in the multivariate case without the assumptions of independent identically distributed variables. We develop the computationally tractable subcase of simplicial information cohomology represented by entropy Hk and information Ik landscapes. The I1 component defines a self-internal energy functional Uk, and (−1)k Ik,k≥2 components define the contribution to a free energy functional Gk of the k-body interactions. The set of information paths in simplicial structures is in bijection with the symmetric group and random processes, provides a topological expression of the 2nd law and points toward a discrete Noether theorem (1st law). The local minima of free-energy, related to conditional information negativity and the non-Shannonian cone of Yeung [4], characterize a minimum free energy complex. This complex formalizes the minimum free-energy principle in topology, provides a definition of a complex system, and characterizes a multiplicity of local minima that quantifies the diversity observed in biology. Finite data size effects and estimation bias severely constrain the effective computation of the information topology on data, and we provide simple statistical tests for the undersampling bias and for the k-dependences following [5]. We give an example of application of these methods to genetic expression and cell-type classification. The maximal positive Ik identifies the variables that co-vary the most in the population, whereas the minimal negative Ik identifies clusters and the variables that differentiate-segregate the most. The methods unravel biologically relevant I10 with a sample size of 41. It establishes generic methods to quantify the epigenetic information storage and a unified epigenetic unsupervised learning formalism.
Cell Propagation of Cholera Toxin CTA ADP-Ribosylating Factor by Exosome Mediated Transfer

Published: April 2018

Here we first report, how cholera toxin (CT) A subunit (CTA), the bacterial enzyme moiety responsible of cell signaling alteration, can take over the exosomal pathway, spread extracellularly and be transmitted in a cell population. A first evidence for long-term transmission of CT toxic effect via extracellular vesicles was obtained in CHO cells. To follow CT intracellular route towards exosome secretion we adopted a strategy apt to convert multivesicular body (MVB) derived exosomes in traceable fluorescent vectors. CT treated Me665 cells, a human melanoma cell line highly expressing caveolin-1 (Cav-1) and GM1, were used to purify and characterize fluorescent exosomes. Our results clearly show association of CT with exosomes together with typical exosomal markers and the HSP90 and PDI molecules, the required membrane translocation elements of CTA to the cytoplasm. Confocal microscopy proved direct CT containing fluorescent exo transfer into CHO cells coupled with the morphological cell change characteristic of CT action. Moreover, direct assessment of cAMP levels in Me665 cells treated with CT containing exo showed an efficient induction of cAMP increase comparable with CT alone. From our results, we can infer that CT can exploit exosome-mediated cell communication to target and extend its pathophysiological action throughout cell tissues.

Papel de la sensibilización central en la cronificación del dolor postquirúrgico
Authors: Sanisidro Torre Roberto
Published: April 2018

El dolor crónico posquirúrgico (DCPQ) es un cuadro clínico que dura al menos tres meses tras una intervención quirúrgica, donde adicionalmente se observan síntomas dolorosos neuropáticos.  El prerrequisito para el desarrollo de DCPQ es una lesión a los nervios principales que discurren por el lecho quirúrgico. En un estado basal, un estímulo nocivo despolariza una neurona sensitiva (nociceptor); ese nociceptor, en la médula espinal transmite la señal a una neurona espinal que envía la señal al tálamo; desde el tálamo se estimulan distintos centros cerebrales; la corteza prefrontal integra toda la información y el paciente siente dolor.  En ocasiones, no existe relación entre el estímulo doloroso y la respuesta que origina en el SNC: es entonces cuando se produce una importantísima amplificación de la señal nociceptiva, y a este fenómeno se le conoce como sensibilización neuronal o neuropatía, de forma que la información transmitida al cerebro origina una reacción dolorosa desproporcionada. Este desarreglo se produce tanto a nivel periférico (sensibilización periférica) como a nivel central (sensibilización central). Existe una nueva línea de abordaje, que evalúa los factores de riesgo: como el dolor postoperatorio agudo severo, las técnicas quirúrgicas mínimamente invasivas y las estrategias analgésicas preventivas multimodales; como factores sobre los que podemos ser capaces de influir en aras de evitar el desarrollo de esta sensibilización que favorece la cronificación del dolor.

Abstract

Seismo-electromagnetic effects occurring in wide frequency range that preceded earthquake have been widely reported in several previous studies. The effect is expected to be utilized in earthquake disaster mitigation. This study discusses application of magnetic polarization correlation method of Z / H component to identify earthquake precursors around Pelabuhan Ratu. Data used are three components magnet data for 31 days before earthquake events. Identification of magnetic anomaly was done by applying the magnetic polarization Z / H method to calculate correlation coefficient ratio (Skk) with standard deviation of correlation coefficient deviation (Dskk). The anomaly threshold is -1. Less than -1 of Skk / Dskk values indicate geomagnetic anomaly. The emergence of geomagnetic storms that affect geomagnetic anomalies is evaluated using the Disturbance storm time index (Dst index). The result of application of Z / H magnet polarization correlation method in five earthquake cases around Pelabuhan Ratu from January to March 2017 with magnitude M > 4 and meeting precursor manifestation radius zone showed the occurrence of geomagnetic anomalies categorized as earthquake precursors. The appearance of geomagnetic anomalies ranged from 16 to 2 days before earthquakes occurred.

Kompleksitas struktur pori terhubung pada sampel digital medium berpori 2D telah dianalisis menggunakan parameter tortuositas. Jalur pori terhubung dilacak dengan menggunakan Simple Neurite Tracer. Metode pelacakan dan perhitungan tortuositas tersebut diujikan pada lima model sederhana yang menunjukan perbedaan tingkat kompleksitas yang signifikan. Metode analisis kompleksitas tersebut kemudian diterapkan pada sampel medium berpori berupa citra digital batuan berukuran 560 × 393 piksel, dan tanah berukuran 560 × 475 piksel. Citra digital sampel tanah dan batuan yang dianalisis berupa irisan 2D pada bidang z-y (sagittal) yang diambil dari sampel 3D hasil pemindaian menggunakan -CT Scanner SkyScan 1173. Pelacakan jalur pori terhubung pada sampel model maupun sampel digital 2D batuan dan tanah yang menggunakan Simple Neurite Tracer menghasilkan koordinat jalur pori terhubung yang kemudian digunakan untuk menghitung nilai tortuositas. Tortuositas dihitung dengan menggunakan definisi rasio antara jumlah total sudut keberlikuan jalur terhadap jarak antara dua sisi sampel yang saling berhadapan. Untuk 5 sampel model yang menunjukkan kompleksitas yang berbeda, diperoleh bahwa semakin kompleks struktur pori tersebut, maka semakin besar nilai tortuositasnya. Untuk analisis pada sampel digital batuan, nilai tortuositasnya yaitu 0,0392 sedangkan pada sampel tanah didapat nilai tortuositas sebesar 0,0431.

Abstract

The complexity of the connected pore structure of 2D porous digital media samples has been analyzed using tortuosity parameter. Connected pore was traced using the Simple Neurite Tracer. The tracing method and the tortuosity calculation were tested on five simple models showing significant differences in complexity levels. The complexity analysis method was then applied on digital image of a rock sample with the size of 560 × 393 pixels, and a soil sample with the size of 560 × 475 pixels. Digital images of the rock and soil samples were analyzed on the 2D slices in the zy (sagittal) plane which were obtained from the scanned 3D samples using the µ-CT SkyScan 1173 Scanner. Connected pore tracing for both the 2D models as well as the rock and soil samples was done using the Simple Neurite Tracer which produce the coordinate of the connected pore path which is then used to calculate the value of tortuosity. Tortuosity is calculated by using the definition of the ratio between the sum of the curvaceous angles of the connected pore path to the distance between two facing sides of the sample. For 5 sample models with distinctive complexity, it was found that the more complex the pore structure, the greater the tortuosity value. For analysis on digital samples of rocks, the tortuosity is 0.0392 whereas in the soil sample, the tortuosity is 0.0431.

Abstract

Eddy current sensor is used to measure the thickness of metals, especially non-magnetic metals such as aluminum. This research has developed eddy current sensor made from PCB (printed circuit board) type FR4 which has 35micron copper layer thickness. The developed prototype uses a designed coil sensor with the number of winding (n) 30 turn, diameter () 30mm, width and distance between coils, (dkoil) 0.254 mm and coil resistance (Rkoil) of 4.26 Ω. The sensor response to the test material was evaluated by giving a single frequency excitation of 700 Khz, 1 MHz and 1.33 MHz. The plate thickness electronics has used a phase locked loop circuit and is capable to measure the thickness variations from 0.2 mm up to 2 mm, while the distance between the sensor coil and the test object was kept constant at 2 mm. The measurement results give the U (t) curve response in the exponential relationship.

Training-Image Assisted History Matching of Complex Multiple-Point Statistical Facies Models: A Pattern-Based Approach
Authors: Khaninezhad M. , Golmohammadi A. , Jafarpour B.
Published: April 2018

Traditional geostatistical methods that rely on two-point statistics (i.e., variogram models) to describe the spatial variability in rock properties are not appropriate for representing the spatial continuity patterns associated with complex geologic objects (e.g., curvilinear fluvial patterns and turbidite systems). Modern geostatistical techniques are developed to simulate multiple-point statistical (MPS) patterns from a training image (TI), as a conceptual model of geologic continuity, to generate model realizations with complex geologic connectivity. A major difficulty in using MPS methods is related to conditioning the simulation results on nonlinear dynamic production data. We develop a pattern-based model calibration approach for conditioning MPS-based facies models on nonlinear flow data. The formulation begins with defining a minimization problem in which the mismatch between predicted and observed production data is minimized. Since facies distributions are discrete variables, we use a parameterization method to transform them into a small number of continuous parameters that can be updated using gradient-based minimization. For this purpose, k-SVD sparse dictionary learning is adopted to approximate the connectivity patterns in the distribution of facies models. Because of the approximation involved in the k-SVD parameterization, an additional step is introduced, after each iteration, to map the resulting continuous models to the TI. To implement the mapping, a local search template is used to scan the TI to find local discrete patterns with smallest distances from the corresponding local patterns in the continuous solution. This process is repeated for all the grid cells in the continuous solution and the resulting local patterns are stored. To estimate the facies type in each grid cell, the collected patterns that intersect with any given cell are used to find the facies type with the highest frequency and assign it to that cell. Once the discrete solution is identified, it is passed to the continuous minimization problem to serve as a regularization term, for the next update iteration. The process is repeated until the discrete solution provides an acceptable match to the data. Numerical experiments are presented to evaluate the performance of the proposed approach for facies calibration in complex fluvial systems. The results suggest that the developed method presents a promising pattern-based approach for integration of production data into MPS-based facies models.
Surviving the New Oil Price Landscape: A Case Study Breaking Down Liquid-Rich Basins in the Rockies
Authors: Srinivasan Karthik , Krishnamurthy Jayanth , Borchardt Shannon
Published: April 2018

The oil and gas production landscape in North America has seen a paradigm shift since the collapse in oil prices in 2014. Although prices remain challenging, several operators have managed to sustain the relatively long period of low margins through some aggressive approaches. This paper inspects changes in operating strategies and field development plans across all oil-rich basins in the US Rocky Mountain fields and how operators have used a combination of low oilfield service prices, high-graded well locations, and incremental fluid/proppant volumes to increase production.

The paper investigates the transformation in operating philosophies since 2014 in four oil-rich basins in the Rocky Mountain region—Williston, Denver-Julesburg (DJ), Uinta, and Powder River. The Bakken formation in the Williston basin represents one of the best-quality rocks in all of North America. However, high oil-price differentials and well costs have made it difficult for drilling to remain profitable. The core of the DJ basin (Wattenberg) has one of the lowest break-even prices in the region, and rig count continues to increase as operators start seeing signs of recovery in the market. The Uinta basin, although relatively small in size, has shown tremendous return potential in the form of multiple stacked pays and promising production results. The Powder River basin poses one of the toughest operational environments in the region owing to wildlife stipulations, harsh weather, and deeper targets.

High-graded well locations in the Bakken are limited to few fields, which limits the scope of expansion in the current oil price environment. The DJ basin is challenged with high-density well spacing; estimated ultimate recovery (EUR) per drilling spacing unit (DSU) continues to increase, but EUR per well has gone down by as much as 60%. In the Uinta basin, formations never known to be continuous in the Green River group have shown significant return potential. The Powder River basin has recently attracted large investments from major independent operators as they tackle drilling challenges associated with abrasive rocks and testing optimum lateral landing points.

Case studies show how operating strategies have changed with changes in oil prices. The Bakken and DJ basins are relatively mature, and as drilled-but-uncompleted (DUC) inventory continues to increase, depletion from existing wells and interference between fractures is impacting production from new wells. The Powder River basin is still in the exploratory phase, and operators are still working on reducing well-costs, optimizing fracturing-fluid/proppant volumes, and examining productivity of other target rocks. The Uinta basin is in the early phases of expansion, with many of the fields still being explored for scalability. Changes in production maps and completion trends provide a comprehensive understanding of how these variables have impacted oil output from the region since 2012.
