Collapse Analysis of Perforated Pipes Under External Pressure
Authors: Carpenter Chris 
Published: July 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 184946, “Collapse Analysis of Perforated Pipes Under External Pressure,” by K. BeltrÁn and T. Netto, Federal University of Rio de Janeiro, prepared for the 2017 SPE Latin American and Caribbean Mature Fields Symposium, Salvador, Bahia, Brazil, 15–16 March. The paper has not been peer reviewed.
This work is a study of collapse pressure of perforated pipes to evaluate the effect of lateral perforations on the radial resistance of pipes under external pressure. These types of pipes represent a simple and economical technology widely used as sand-control meshes or perforated liners.
Introduction
One of the most common challenges to high flow rates in mature fields is the migration of sand to the well. High rates of oil production together with maximum sand retention is the optimal result. In accomplishing this complex goal, perforated pipes play a vital role because they are a simple and inexpensive application, and they are widely used in the industry. Failures of such pipes are directly related to the collapse resistance of a pipe weakened by the perforations. Such failures can occur because of the plugging of holes or changes in differential pressure. This study might contribute to future prediction of collapse pressures of perforated pipes without resorting to costly full-scale experiments.
Methodology Development
Geometric Properties. This study involves four intact and eight perforated specimens as study bodies. All of them were obtained from four pipes designated as T3, T4, T5, and T6. A special nomenclature was defined to identify each one with a sequence of letters and numbers. An explanation of this nomenclature is shown in Fig. 1.
The geometrical properties were obtained by means of a physical mapping, taking 10 measurements in the longitudinal direction and five in the circumferential direction to calculate the average thickness, average diameter, and initial imperfections (ovalization and eccentricity) of each specimen.
Material Properties. The mechanical properties were also determined for each specimen by means of traction tests on 18 proof bodies, including some in the longitudinal direction and others in the circumferential direction. After processing the results, the average curves and values for the mechanical properties for each tube were defined. Because of the remarkable differences in shape and behavior of the curves, an average curve was calculated also. The results of monotonic traction tests in the circumferential direction are shown in Table 4 of the complete paper, and the plots are shown in Figs. 3 and 4 of the complete paper.
Technology Focus: EOR Operations (June 2017)

Technology Focus
When I started editing this section in 2015, the year after the oil-price crash, many industry commentators were predicting a strong recovery in oil price by now; instead, the concept of “lower for longer” has become the present reality. Now, many commentators expect a shortfall in supply by the mid-2020s and the effect of shorter-cycle shale oil developments to be just two of the factors affecting price in the future.
Sometimes, I hear the view that, without high oil prices, enhanced oil recovery (EOR) does not have a place in the mix of projects delivering the new production needed over the next decade. However, high oil prices are not the whole story. High oil prices may cause an over-heated market that squeezes the value from EOR. By their nature, EOR projects are often longer-term investments, so investing in new EOR projects at a time when real-term costs are at their highest (pushed by the high oil price) may not be the best strategy.
Significant progress in cost reduction has been made in the industry following the price downturn, not only in the direct cost of construction and operations but also through a determined drive to simplify and streamline new projects in concepts selected for facilities and wells. Through this competitive scoping, project economics can be improved to deliver more-robust investment opportunities.
The discipline of a lower-for-longer world can create the conditions in which long-term investment decisions can be made. In the mix of new projects needed to fill any production shortfall in the coming decade, brownfield improved and enhanced oil recovery can compete with the alternatives available to the industry.
SPE continues to play an important role in sharing best practices to allow the industry to reap the benefit of project learnings, and I hope you find that the selected papers and recommended reading provide useful insights.

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 179569, “Overview of CO2 Injection and WAG Sensitivity in SACROC,” by Reza Barati Ghahfarokhi, SPE, The University of Kansas, and Steve Pennell, Michael Matson, SPE, and Mark Linroth, SPE, Kinder Morgan, prepared for the 2016 SPE Improved Oil Recovery Conference, Tulsa, 11–13 April. The paper has not been peer reviewed.
This paper presents an overview of the SACROC Unit’s activity focusing on different carbon dioxide (CO2) injection and water-alternating-gas (WAG) projects that have made the SACROC unit one of the most successful CO2 injection projects in the world. The main objectives of this were was to review CO2 injection and injection-rate losses with respect to the CO2/WAG miscible displacement process in the SACROC Unit and recommend an injection strategy for WAG-sensitive patterns.
Introduction
The Kelly-Snyder field is the largest of a chain of fields along the Pennsylvanian Horseshoe atoll in the Midland Basin. Within this field, the Scurry Area Canyon Reef Operators Committee (SACROC) Unit covers approximately 56,000 acres with 2,800 million STB of original oil in place (OOIP). Limestone is the dominant mineral within the Canyon Reef formation, and less than 3% of the formation exists as thin sections of shale (1–10 ft in thickness) that are important stratigraphic markers. The formation is divided into four major zones: the Cisco, the Green Zone (GZ), the Upper Middle Canyon, and the Lower Middle Canyon (LMC). Of these, the GZ shows the highest matrix permeability, significant nonmatrix-flow features, and high-conductivity channels. Moreover, the transition zone (TZ) below the oil/water contact has recently been developed in parts of the SACROC Unit.
Review
Primary Production. Completed in November 1948, the Standard No. 1 Jessie Brown 2 was drilled to 6,700 ft and produced 530 B/D from the Canyon Reef Formation. Located 9 miles northwest of Snyder, Texas, this well was the discovery well of the North Snyder field. The Texas Railroad Commission eventually merged this field with the neighboring Kelly field upon recognizing that both fields produce from the same reservoir. The reservoir thickness varies from 10 ft on the flanks to 900 ft on the crest of the reef. A map of the unit’s 3D structure and thickness is shown in Fig. 1. By late 1950, 1,600 production wells had been drilled on the Kelly- Snyder field on irregular 40-acre spacing.
Predicting Factors of Depression, Antidepressant Use and Positive Response to Antidepressants in Perinatal and Postpartum Women
Authors: Vu Huyen , Shaya Fadia T. 
Published: July 2017

Background:
In the United States, there is a disparity in knowledge of nationwide depression prevalence, the antidepressant use and the antidepressant responses during perinatal/postpartum periods.

Objective:
This study investigated the predicting factors of depression, antidepressant use and positive antidepressant response during the perinatal/postpartum periods.

Method:
The 2007-2012 National Health and Nutrition Examination Surveys (NHANES) were combined to identify adult pregnant women, those within the 18-month postpartum period (n=492) and their depression statuses via demographics, health care accessibility, antidepressant use and illicit drug use information. The characteristics of different study groups were compared (depression versus no-depression groups, antidepressant users versus non-antidepressant users, and antidepressant responders versus antidepressant non-responders). Multivariable logistic regression analysis was used to predict factors of perinatal depression (PND)/ postpartum depression (PPD), antidepressant use and antidepressant positive response in PND/PPD.

Results:
PND/PPD individuals had higher rates of mental health visits. No predicting factor for developing PND/PPD was shown. Antidepressant users were significantly older with insurance and recent health checkups/ mental visits. Being below the poverty level and having some health care accessibility are predictors for being on antidepressants. Recent non-illicit drug use is a predictor for PND/PPD symptom improvement while on antidepressants.

Conclusion:
The group of those with social-economic disadvantages was more likely to be on antidepressants for PND/PPD. Illicit drug users were less likely to show improvement with antidepressants. The safety and efficacy of antidepressant use during this period is controversial. More studies need to focus on the barriers involving antidepressant treatments, the safety and outcomes of antidepressants for PND/PPD management.

Published: July 2017

Objective:It is aimed to determine whether fasting during Ramadan has any significant effect on anterior chamber parameters, visual acuity and intraocular pressures.Methods:31 fasting (Group 1) and 30 non-fasting healthy volunteers (Group 2) were enrolled. All cases underwent an ophthalmological examination and anterior segment parameter evaluation (central corneal thickness (CCT), anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), pupil size) with Pentacam before and after the breaking of the Ramadan fast in Group 1, before and after dinner in Group 2.Results:The mean age was 43.35 ± 13.20 in Group 1, 43.17 ± 12.90 in Group 2 (p= 0.955). No significant difference was detected in any of the parameters in both groups.Conclusion:There is a need for more detailed and associated studies to understand better about the influence of Ramadan fast on various ocular parameters.
Efficacy and Safety of Switching from Prostaglandin Analog Therapy to Prostaglandin / Timolol Fixed Combination or Prostaglandin / Brimonidine Therapy
Authors: Inoue Kenji , Masumoto Mieko , Ishida Kyoko , Tomita Goji 
Published: July 2017

Background:
To compare the safety and efficacy between switching to prostaglandin/timolol fixed combination eye drops (PG/timolol FCs) and adding brimonidine to PG analogue monotherapy.

Methods:
Eyes of 53 patients with primary open-angle glaucoma or ocular hypertension who were receiving PG analogue monotherapy were included. Participants were randomly divided into two treatment groups: one was prescribed PG/timolol FCs (switched group), and for the other, 0.1% brimonidine was added to the PG analogue (added group). Intraocular pressure (IOP), blood pressure, and pulse rate were measured after 1 and 3 months and compared to baseline values. Participants were also surveyed to determine if they had experienced systemic or topical adverse events at each study visit. IOP changes at 1 and 3 months were compared between groups.

Results:
Three months after changing medication, mean IOP was 14.6 ± 2.4 mmHg in the switched group and 13.7 ± 1.8 mmHg in the added group; both were significantly lower than the baseline values (switched group, 16.5 ± 2.7 mmHg; added group, 15.8 ± 2.3 mmHg; both P < 0.001). Neither the mean nor the percentage reductions in IOP were significantly different between groups at 1 and 3 months. In the added group, diastolic blood pressure was lower than that at 1 and 3 months, systolic blood was lower than that at 3 months (P < 0.01). The patients who had experienced systemic or topical adverse events were 53.8% in the added group and 40.7% in the the changed group, which was equivalent between groups (P =0.4142). Three patients (11.5%) in the added group, but none from the switched group, were excluded from analyses because of adverse events (not significant, P = 0.217).

Conclusion:
Switching from a PG analogue to PG/timolol FCs or to PG with brimonidine was equally safe (systemically and topically) and effective in reducing IOP. Thus, PG with brimonidine might be appropriate medication in patients who cannot use PG/timolol FCs due to repiratory or circulatory disease.

O ser humano cooperador com Deus: Ética cristã a partir dos dois regimentos e três estamentos na teologia de Martim Lutero
Authors: Wachholz Wilhelm 
Published: July 2017

A doutrina da justificação por graça através da fé, que caracteriza a teologia de Martim Lutero, perpassa também sua última grande obra, a Preleção sobre Gênesis. Tudo que Deus criou é bom e serve para o benefício do ser humano. Pelo pecado, contudo, o ser humano se afastou de Deus e de toda a criação, da vida para a morte. Deus, em sua misericórdia e graça, não abandona o ser humano, mas o procura, chama para a reconciliação, cuja expressão mais concreta é o próprio Cristo. Deus reconcilia o ser humano, tornando-o justo para relações justas. O objetivo deste artigo é analisar, na teologia de Lutero, o ser humano justificado por Deus para ser justo cooperador de Deus para o melhoramento do mundo. O percurso da análise considerará a queda do ser humano no pecado, a relação entre os dois regimentos e os três estamentos, bem como ministérios e vocação com vistas à cooperação da pessoa cristã com Deus através de igreja, economia e política.
Permanent Switchboard Monitoring using Embedded Web Server

Published: July 2017

The proposed paper discusses the realization of a system prototype able to perform a permanent monitoring of a switchboard in order to allow the manufacturer the complete management of all the measurable quantities in the switchboard, specially the sensed voltage for each line. The main purpose is to prevent any fault that can affect the switchboard and provide an instant alarming if anomalous values are revealed. The significant aspect of our prototype is the internetworking between several standard network protocols. In fact, the acquisition network sends the acquired data using the EIA 485 serial protocol. These data are then collected into an embedded web server ad-hoc developed. The server can be connected to the Internet in a wired and/or wireless way using the IEEE 802.3 (Ethernet) and the IEEE 802.11 (Wi-Fi) protocols. Finally, the web server uses standard TCP/IP protocols, such as HTTP to manage the web pages and SMTP to dispatch automatic alarm notifications via e-mails.

Published: July 2017

Fecha de recepción: 1 de diciembre de 2012.Fecha de aceptación: 3 de octubre de 2013. El presente trabajo se centra en la documentación y en la distribución geográfica (histórica y actual) de los llamados gerundios ‘analógicos’ del español (tuviendo, quisiendo), sobre la base de los datos de varios corpus lingüísticos (CORDE, CREA, Corpus del español, ALPI y COSER). Revisamos las explicaciones analógicas previas sobre estas formas y establecemos una explicación sobre la extensión del tema de perfecto al gerundio, basada en el condicionamiento fonológico. También defendemos que la explicación fonológica está en relación con las nociones estables del cambio morfológico, desde la teoría de la morfología natural.

Fecha de recepción: 12 de febrero de 2013.Fecha de aceptación: 28 de marzo de 2013. La dedicatoria de la primera Égloga de Garcilaso de la Vega (“El dulce lamentar…”) tiene como modelo la dedicatoria de la Égloga VIII de Virgilio, pero también la de la Égloga V de las Piscatoriae de Sannazaro.Se rastrea la importancia de este segundo modelo para los imitadoresde Garcilaso. Su “patrón triádico” enfatiza la importancia de la caza, presente en Sannazaro pero no en Virgilio. Adquiere tanto en las dedicatorias de la primera Soledad y del Polifemo de Góngora una importancia central, demostrando cuánto el poeta cordobés le debe al modelo piscatorio del napolitano Sannazaro.

Economics of Sustainable Development as a Trend in Modern Economics: An Overview
Authors: Zalega Tomasz 
Published: July 2017

The concept of sustainable development, and thus the evolution of the economics of sustainable development, became a subject of increased interest for researchers and businesses after the first UN Conference in Stockholm in 1972, and then after the second Earth Summit in Rio de Janeiro two decades later. It is at the second Earth Summit with its “Environment and Development” motto, which was attended officially by 172 countries and approximately 2400 representatives of nongovernmental organisations, where unsustainable consumption Summary Economics of Sustainable Development as a Trend in Modern Economics: An Overview and production were recognised as the most important causes of growing global development problems. Attempts were made to find models of sustainable and stable economic development that took into account the protection of ecosystems from overexploitation and determinants of ecological human activity. It was no accident that this process coincided with the progress of economics of sustainable development. This article aims at providing an insight into economics of sustainable development and presenting its historical roots. The issues herein do not describe its whole range, but only selected elements. The structure of this article is as follows. The first part focuses on the origins, concept and principles, objectives and orders of sustainable development. Further, the concept and assumptions of sustainable development economics and homo sustinens as the basic underlying notion are discussed.
Emigration of Nepalese People and Its Impact
Authors: Kunwar Laxman Singh 
Published: July 2017

This paper reflects the emigration history of Nepalese people and their destinations with role of remittances in country of origin (Nepal). The number of emigrants and share of remittances in terms of GDP has been increased but at the same time various negative impacts have been emerged in Nepalese society. In addition trade deficit has been increased and Nepalese emigrants who are working abroad are not being able to receive their rights at their working place. Discriminations in terms of earning and other privileges are common for Nepalese emigrants and due lack of skills, trainings and low level of education mainly 3D (Difficult, Dirty, Dangerous) jobs secured at their working places, as a result the earning/remittances are also low. This paper is based on secondary sources of information and briefly explains the history of emigration and its impacts in socio-economic sectors of Nepal.
