A gestão do Poder Judiciário sob a ótica de ex-conselheiros: análise da relação entre o CNJ e a Justiça Estadual de 2004 a 2013
Authors: Oliveira Leonel Gois Lima
Published: December 2019

O objetivo de pesquisa consiste em analisar a interação do CNJ com os tribunais estaduais em busca de melhorar os níveis de eficiência da Justiça Estadual no período de 2004 a 2013 na ótica dos ex-conselheiros. Os principais questionamentos a serem respondidos foram:  De que forma os esforços e ações realizados pelos Tribunais de Justiça estaduais para se adequaram as exigências do CNJ visando à melhoria da eficiência da prestação jurisdicional? Em que medida tem ocorrido uma convergência de esforços e alcance de resultados entre o CNJ e os Tribunais Estaduais para a melhoria da eficiência? Foram entrevistados 20 ex-conselheiros, adotando-se a análise temática ou categorial como forma principal de técnica de análise de conteúdo. As categorias estabelecidas para análises foram relacionadas ao predomínio de divergência (desconfiança e resistências), ao predomínio de convergência (aceitação e integração) e à alternância de cenários (relativismo e contexto de autonomia). De forma geral, os respondentes apontaram a existência de uma convergência de esforços entre o CNJ e os Tribunais de Justiça estaduais que foi sendo fortalecida na medida em que o desconhecimento e a desconfiança sobre o CNJ foram se dissipando. Percebeu-se que a relação de convergência e divergência apresenta alternâncias cíclicas, pois o entendimento alterar conforme a percepção de perda de autonomia por parte dos tribunais.

Este estudo teve como objetivo a elaboração de um programa de secagem da madeira de Pterodon emarginatus que é uma espécie nativa do Cerrado, amplamente utilizada na produção de madeira, principalmente para indústria de base florestal, em todo o Brasil. Para a realização deste trabalho foram confeccionados 10 corpos de provas para a determinação da densidade básica e retratibilidade com dimensões de 4,5x2,0x2,0 cm, e para o programa de secagem foram utilizados 10 amostras com dimensões de 15x4,5x1,0 cm, referentes a comprimento, largura e espessura. A secagem dos corpos de prova foi realizada segundo a metodologia de secagem drástica a 100°C adaptado por Ciniglio (1998). Os resultados demonstram que a madeira de Pterodon emarginatus possui uma densidade básica de 0,800 g.cm-3, classificando está madeira como moderadamente pesada. Sua umidade inicial foi de 70,61%, calculado por meio do método gravimétrico. O colapso foi o principal defeito observado nas amostras que apresentou valor de 0,450mm, sendo assim classificada como baixo grau de colapso. Os principais parâmetros do programa de secagem foram temperatura inicial (40,77), temperatura final (63,13) e potencial de secagem (1,8), o programa gerou uma secagem difícil para a espécie, indicando temperaturas mais baixas na secagem a fim de evitar defeitos severos na madeira.
Estéticas das resistências e o documentário: Diário de Exus

Published: December 2019

De 2013 a 2016, foram desenvolvidos três projetos de documentário sob minha direção, na região metropolitana de Campinas-SP, que resultaram na “Trilogia Afro-Campineira”. São três curtas-metragens focados em protagonistas de processos culturais, religiosos e artísticos, todos defensores de manifestações de matrizes africanas e seus potentes hibridismos. Os filmes são Diário de Exus (2015), A Dança da Amizade, Histórias de Urucungos, Puítas e Quijengues (2016) e A Mulher da Casa do Arco-Íris (2017/2018). Todos os filmes tiveram fontes de financiamento como FAEPEX/UNICAMP, FICC e Prêmio Estimulo ao Curta-metragem do Estado de São Paulo e contaram com uma rede de parceiros, da universidade (UNICAMP) e das comunidades e pontos de cultura envolvidos. Desenvolvem-se, nos filmes, o que nomeio como as “estéticas das resistências”, priorizando narrativas afro-diaspóricas, num processo de criação em que confluem estética e política. Esteticamente, trata-se de destacar a convergência e a disputa dos modos observativos, participativos, poéticos e performáticos de realização documentárias, voltados para sujeitos portadores de códigos culturais afrocentrados. Politicamente, realçam-se o papel da cultura e da religião na afirmação e construção identitária do negro, no Brasil. Esse texto documenta o processo de realização do primeiro curta-metragem, Diário de Exus.

Authors: Handayani Dewi , Laksono Dhony Eko , Novitiana Lydia
Published: December 2019

Banyaknya kasus kecelakaan yang terjadi tersebut dapat disebabkan karena padatnya kendaraan yang ada di jalan sebagai akibat dari meningkatnya jumlah pengendara, terutama pengendara sepeda motor, yang seringkali menimbulkan tingkah laku agresif. Kepadatan seringkali memiliki dampak pada manusia, salah satunya yaitu timbulnya perilaku agresif (Sarwono, 1995). Hal ini dikarenakan tindakan agresif merupakan tindakan paling umum yang ditampilkan pada saat berada dalam kondisi padat (Konecni, 1975, dalam Mann, dkk, 1982). Aggressive driving adalah suatu perilaku yang direncanakan untuk menyerang secara fisik, emosi atau psikologi di lingkungan mengemudi atau jalan raya. Selanjutnya, Tasca (2000) menambahkan bahwa, aggressive driving dilakukan secara sengaja, cenderung meningkatkan risiko kecelakaan dan dimotivasi oleh ketidaksabaran, kekesalan, permusuhan, dan atau upaya untuk menghemat waktu.  Perilaku aggressive driving tidak selamanya berujung selamat karena berdasarkan data yang relah diuraikan, terbukti banyak sekali kecelakaan lalu lintas yang disebabkan oleh perilaku aggressive driving. Tujuan penelitian untuk mengetahui karakteristik remaja pengendara sepeda motor dan mengetahui Pengaruh Perilaku Agresif (Aggressive Driving) Terhadap Potensi Kecelakaan Pengendara Sepeda Motor Remaja. Metode penelitian menggunakan analisis jalur dengan program AMOS 20.0. Pengumpulan data menggunakan kuisioner dengan skala likert yang diberikan kepada responden. Responden terdiri dari 360 remaja pengendara sepeda motor yang merupakan pelajar tingkat Sekolah Menengah Atas (SMA) yang terdaftar sebagai Sekolah Pelopor Keselamatan di Kota Surakarta. Hasil penelitian menunjukkan remaja pengendara sepeda motor di Kota Surakarta yang memiliki SIM C hanya 23.33%. Sebesar 94.44% remaja telah mengendarai sepeda motor sebelum usia 17 tahun. Pengaruh simultan pengaruh berkendara agresif terhadap potensi kecelakaan lalu lintas pada remaja pengendara sepeda motor di Kota Surakarta adalah sebesar 68,60%. Perilaku berkendara memegang peranan penting terhadap potensi kecelakaan lalu lintas sehingga diperlukan suatu kebijakan agar pengendara sepeda motor lebih tertib dan taat pada aturan lalu lintas.

The aim of this work was to investigate the influence of the addition of polypropylene, polyester, polyamide, aramid and aramid pulp fibers on the behavior of concretes subjected to high temperatures. For that, test specimens with fiber additions were made at a rate of 2 kg/m3 and submitted to temperatures in furnace, as well as to high temperatures through direct fire test. Columns were also built and subjected to a live fire simulator belonging to the Espírito Santo Fire Department - Brazil. Microstructural and mechanical properties were analyzed. It has been observed that the fibers may influence the properties of the concrete and that fire tests with standard fire load may be an alternative or complementary analysis of concrete subjected to elevated temperatures.
Primary Arthroscopic Stabilization for a First-Time Anterior Dislocation of the Shoulder
Authors: Yapp Liam Z. , Nicholson Jamie A. , Robinson C. Michael
Published: December 2019

Background:

The aim of this study was to evaluate the long-term efficacy of arthroscopic Bankart repair (ABR).

Methods:

Eighty-eight patients with an age of ≤35 years who had sustained a primary anterior glenohumeral dislocation were enrolled in a single-center, double-blinded clinical trial. Subjects were randomized to receive either an arthroscopic washout (AWO) or ABR. Participants were reassessed after a minimum of 10 years postoperatively. Data regarding recurrent instability, revision surgery, satisfaction, and function (Disabilities of the Arm, Shoulder and Hand [DASH] and Western Ontario Shoulder Instability Index [WOSI]) scores were collected.

Results:

Sixty-five patients (74%; 32 in the AWO group and 33 in the ABR group) were included and had an average follow-up of 14.2 years (range,12 to 16 years). The rate of recurrent dislocation was significantly higher in the AWO group than the ABR group (47% and 12%, respectively; p = 0.002). Kaplan-Meier curves were plotted for event-free survival using recurrent instability and/or revision surgery as clinical end points. This analysis demonstrated a sustained significant difference between the groups at 10 years after surgery (58% for the AWO group versus 79% for the ABR group; log-rank test [Mantel-Cox]; p = 0.018). Long-term WOSI scores were significantly better in the ABR group. The presence of recurrent instability was associated with significantly poorer WOSI and DASH scores.

Conclusions:

This study demonstrates a long-term benefit in overall shoulder stability and functional outcome in high-risk patients who have undergone ABR for first-time anterior dislocation.

Guest Editorial: Permian Shale Water Management: The Hidden Costs
Authors: Henthorne Lisa , Boysen Buddy
Published: December 2019

Guest editorial

Water management in shale plays is an extremely competitive business. Every cent counts. This is most evident in the Permian Basin where companies work tirelessly to minimize operating costs in order to contract new capacities and fill their capital-rich infrastructure. These players are under enormous pressure to evaluate every component of costs and wring out excesses. While traditional operating expenses (OPEX) are heavily scrutinized, a full picture of profitability in water management is gained only after comprehensively examining the unique aspects of their overall business model.

Traditional OPEX components in produced water management include labor, chemicals, consumables, infrastructure maintenance, transportation, disposal, solids handling, and power and other utilities.

Capital expenses (CAPEX) must also be considered in light of tradeoffs between CAPEX and OPEX. Water CAPEX is generally composed of infrastructure, including pipelines, disposal wells, ponds/storage treatment facilities, and associated utilities infrastructure; equipment; engineering, project management, and permitting costs; and land.

While all companies focus on these key expenses, another very significant cost driver emerges when the business model is more closely examined.

Midstream companies’ revenues originate from three primary sources:

Handling fees. Operators pay companies to collect and dispose of their produced water/flowback on a volume basis, and disposal is usually to a saltwater disposal (SWD) well. Gathering fees are charged for pipeline collection and disposal fees are charged for volumes disposed into SWDs.

Commodity-based margins. Companies separate skim oil from disposed volumes and sell oil. In some cases, ownership of the skim oil remains with the operator. Royalties and accounting costs must be considered as a component of the profitability of skim oil sales.

Treatment fees. Instead of disposing to a SWD, companies can treat produced water/flowback and sell recycled water to operators on a volume basis.

The fact that recycling in the Permian is gaining in popularity due to local water scarcity, transportation costs, environmental stewardship, and/or SWD limitations creates additional opportunities for generating new revenue by increasing the volumes of water treated and associated water disposal/delivery fees.

Revenue Bottlenecks

As recycling is more readily adopted, revenues are becoming constricted by a number of factors including: pipeline capacity, treatment facility capacity, water quality fluctuations that cause upsets in facility operations, and transportation distances/location to fracturing sites.
What’s the Difference Between Tier 1 and Tier 2? Not much
Authors: Rassenfoss Stephen
Published: December 2019

Financial reports have long lumped shale acreage like cuts of meat, with tier 1 for the best reservoir rock, and tiers 2 and 3 ranked as lower quality.

Tier 1 is rated superior to the lower tiers based on a handful of geological measures related to the oil in the ground and the ability to stimulate flow with fracturing.

Production tells another story. A recent study by the energy advisory arm of Deloitte of 35,000 wells in the Permian Basin and Eagle Ford found that production in regions outside tier 1 in those basins are not that different.

“We are starting to challenge that general notion that just investing in established tier 1 acreage drilling a longer lateral, pumping more proppant,” ensures wells that are both productive and profitable, said Tom Bonny, a managing director for Deloitte.

In the Eagle Ford shale, the breakdown in wells based on early production showed little difference between the tiers. Tier 1 wells had a slight edge in wells producing more than 1,500 BOE/D, but was also a bit higher in the percentage of wells at 500 BOE/D or less.

In the Midland Basin, the pie chart for tier acreage showed tier 1 outperformed lower tiers at both the high and low end.

The differences at the high end were relatively small. In the lowest quartile, the percentage of tier 1 wells was significantly lower but 42% of the tier 1 wells were in the bottom quartile, pointing to another problem highlighted by the datA&Mdash;many shale wells are not that productive. In this story, production is based on a 180-day measure that is adjusted as if it were from a 10,000-ft lateral, unless otherwise noted.

The message in the study is that reservoir rock quality matters, but even in what passes for good quality shale rock, getting oil out depends on where the well was located and how it was drilled, fractured, and produced.

“Rock is important, but a good rock without a good design is of less use,” said Anshu Mittal, an associate vice president for Deloitte. 

An average of the splits in the Deloitte pie charts are roughly in line with a rule of thumb offered years ago by George King, now a principal with GEK engineering, who said that for every 10 shale wells, there a couple of bad ones, a handful of marginally profitable performers, and a few strong wells that justify the effort.

What was once a wry observation back when oil prices were $100/bbl now sheds light on a pressing problem after the 2014 price crash forced companies to focus on increasing well productivity.

Operators reacted to that by driving down costs—often by reducing fees for services—and paying more to drill longer laterals and pump more sand.

During those years, the growing use of data allowed those inside the business, and outside, to critically consider the methods used to produce more oil and gas, and whether a well that produced more was worth what was spent to deliver it.
Technology Focus: Mature Fields and Well Revitalization (January 2020)

Technology Focus

Production decline with field maturing is a natural phenomenon, but the efforts to mitigate this decline and, in some cases, even to reverse the trend are truly remarkable. Achieving this feat requires not only a deeper understanding of the subsurface process involved but also a total synergy between the various disciplines engaged in maximizing production from brownfields. This message is apparent in the 90 papers reviewed this year covering various challenging aspects of the topic of mature fields and well revitalization.

The papers reviewed cover a wide range of topics, including the use of novel drilling fluids to target undepleted hydrocarbon layers below the depleted, highly exploited mature hydrocarbon-bearing layers and using novel logging tools to detect thin low-resistivity/low-contrast plays for adding new oil to mature brown-fields. In the current period of industry downturn, creating and executing opportunities to develop mature brownfields has become more economically challenging. Papers describe technical, commercial, and operational aspects that help in achieving an established economic cut-off for project sanction. Several papers describe the use of tools to monitor the status of development using casedhole logs and other resistivity-independent saturation-estimation techniques to locate bypassed oil. Studies have been conducted using classical reservoir engineering tools to supplement findings of detailed reservoir-simulation studies to locate infill wells.

Mature fields generally are believed to be fields having reached their economic limit after primary and secondary efforts. An increasing number of papers reviewed this year, however, also address the issue of refracturing in tight unconventional plays, adding to significant production. The surge in unconventional completions over the past decade has created ample candidates for hydraulic refracturing, and many opera-tors have found refracturing to be a viable alternative to drilling new wells in such formations.

The identification of low-rate leaks along with low annular-pressure buildup rates in any type of completion presents challenges to well integrity. This paper emphasizes the importance of understanding well-diagnostic problems to determine feasibility, isolate interest zones, enhance stimulation strategies, and optimize the acquisition of high-resolution acoustical data from the wellbore with a new leak-detection tool. This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well.

Introduction

The studied well in the Timor Sea offshore Australia was completed as a horizontal gas producer in 2010. The well featured a single packer completion with 7-in./9 5/8-in. tubing and a horizontal lower completion with a swell packer and pre-perforated 5-in. liner. The well contained a production casing (133/8 in.) with an A/B annulus (7-in./9 5/8-in. tubing×13 3/8-in. casing and 11¾-in./9 5/8-in. liners) and surface casing (20 in.) with a C annulus (13 3/8×20 in.).

In late 2016, the pressure of the A/B annulus was observed to have decreased from 10 to 0 barg over a 4-month period, having previously been stable at 10 barg for 1 year. Multiple attempts were made without success to restore pressure by topping up the A/B annulus with inhibited water.

In October 2017, the pressure of the A/B annulus was observed to have a slight vacuum effect of –20 kPa. Diagnostic testing was performed to confirm the issue. The A/B annulus was topped off with 46 m3 of inhibited brine. While filling the last 4 m3, with the A/B annulus confirmed full, the pressure plateaued at 4.25 barg while it continued to pump at 145 L/min, which confirmed a potential leak in the A/B annulus. After the pump was shut down, the A/B annulus pressure stabilized at 3.32 barg, and the fluid levels remained full. The A/B annulus pressure, with the well on line, steadily increased to only 4.2 barg, further confirming the presence of a leak.

In December 2017, a well-integrity logging suite, consisting of an advanced array leak-detection tool and conventional production logging sensors, was conveyed on wireline to determine the A/B annulus leak location. The decision would be made to suspend the well on the basis of the logging results.

This article, written by JPT Technology Editor Judy Feder, contains highlights of paper SPE 194283, “Rapid Deployment and Use of Snubbing Unit Brings Well With Underground Blowout and Surface Broaching Under Control,” by Albert Donaldson, SPE, Victor Marrero-Reyes, and William Scott, Halliburton, and Haitham Al-Mayyan, SPE, Kuwait Oil Company, prepared for the 2019 SPE/ICoTA Well Intervention Conference and Exhibition, The Woodlands, Texas, USA, 26–27 March.

This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time. The mobilization timeline is provided, along with details about how the snubbing unit and BOPs were integrated with existing equipment to enable re-entry into the blowout well. The procedures and equipment used to enable a stable rig-up and well entry are discussed. The paper also describes the situation within the well and the procedures used to bring it under control.

Introduction and Background

A well drilled and completed in 1991 was last worked over and recompleted as a single-zone producer in 2010. On 25 March 2018, the perforated zone was isolated riglessly with a through- tubing bridge plug (TTBP) and dumped cement, and new perforations were added between 3,994 and 4,010 ft. After perforation, wellhead pressure (WHP) was only 90 psi, which was not sufficient to flow the well to the nearby gathering center, and the well was shut in.

On 29 March, the gathering center reported that WHP had increased to 800 psi and that a nearby cathodic protection well had begun producing oil and gas to atmosphere. Investigations were performed on all production wells in the vicinity, and identified the well that was the source of communication with the cathodic protection well. The tubing pressure was found to be 800 psi, and the casing pressure was recorded as 650 psi.

Slickline was mobilized, and on 29 March, a tubing check revealed an obstruction in the tubing at 3,738 ft and provided evidence of damaged tubing at 1,960 ft. Between 29 and 31 March, multiple attempts to kill the well were made with brine weights between 9.0 and 9.6 ppg, followed by oil-based mud (OBM) at 16.0 ppg. Although pressures were temporarily reduced to 0 psi, they quickly returned to 800 psi on the tubing and 650 psi on the tubing by the 7-in. casing annulus. A total of 1,200 bbl of OBM was pumped into the well.

On 3 April, wireline was rigged up, and the logs run indicated that the tubing was severely damaged at approximately 1,951 ft, with many holes and wall loss between 1,296 and 3,727 ft. The 7-in. casing was found to have severe damage between 1,585 and 1,620 ft. Pressure and temperature logs indicated gas flow between the tubing and casing at 1,951 ft.

Background Our aim was to study the morphologic and biochemical changes in the retina and sclera induced by form deprivation high myopia (FDHM) in guinea pigs and explore the possible mechanisms FDHM formation. Methods Forty 3-weeks-old guinea pigs were randomized into the blank control (Group I, 20 cases) and model groups (20 cases). In the model group, the right eyes of the guinea pigs were sutured 8 weeks to induce FDHM (Group II) and the left eyes were considered a self-control group (Group III). The refractive errors were measured were measured with retinoscopy. The anterior chamber depth, lens thickness, vitreous depth and axial length were measured using ultrasonometry A. Retinal and scleral morphology and ultrastructural features were observed with light and electron microscopy. The content of malondialdehyde and the activity of superoxide dismutase in the retina and sclera were detected with a chemical colorimetric assay. Results After remaining stitched for eight weeks, the refractive errors of Group II changed from (+3.59±0.33) D to (-7.96±0.55) D, and these values were significantly higher than those of Group I (+0.89±0.32) D and Group III (-0.55±0.49) D. The vitreous chamber depth (4.12±0.13) mm and axial length (8.93±0.22) mm of Group II were significantly longer than that of Group I [(3.71±0.23) mm and (7.95±0.37) mm, respectively] and Group III [(3.93±0.04) mm and (8.01±0.15) mm, respectively] (P < 0.05). With the prolongation of form deprivation, the retina and scleral tissue became thinner, the ganglion cell and inner and outer nuclear layers of the retina became decreased, and the arrangement was disordered. In Group II, the activity of SOD was significantly lower than that in Group I and Group III, and the content of MDA was significantly higher in Group II than in Group I and Group III. The differences were statistically significant (P < 0.05). Conclusions These findings suggested that in the FDHM guinea pigs model, the refractive errors, the vitreous chamber depth, and axial length increased significantly with prolongation of monocular FD time, and morphological structural changes in the retina and sclera were observed. Oxygen free radicals might participate in the formation of FDHM.
