Authors: Vallejo Vargas Olga I. , Beltrán Leonardo , Franco Paola , Montoya Navarrete Carlos H. , Alzate Rodríguez Edwin Jhovany , Reyes Henry
Published: April 2016

La desinfección del agua con cloro, genera subproductos como los trihalometanos (THM´s), a los cuales se les atribuyen propiedades cancerígenas y con un potencial efecto adverso en el sistema reproductivo. El nivel máximo permitido de THM´s en Estados Unidos es 80 µg/L, mientras que en Colombia es 200 µg/L. En este estudio un método simple, rápido y libre de solventes fue estandarizado para la determinación de THM´s  en aguas para consumo humano utilizando microextracción en fase sólida con espacio de cabeza combinada con cromatografía de gases con detector de microcaptura de electrones  (HS-SPME-GC-mECD) y utilizado para la cuantificación de THM´s en aguas de consumo humano. Fueron estudiados parámetros experimentales así como el tiempo de adsorción, la temperatura de adsorción y desorción, la agitación de la muestra y la adición de NaCl. Se determinaron los límites de detección y cuantificación del método y se realizó el análisis de los trihalometanos de 75 muestras de agua de la planta de tratamiento de Aguas y Aguas de la ciudad de Pereira. Las condiciones optimizadas fueron 20 min de extracción a 37 °C en presencia de 25% de NaCl y con una agitación de 200 rpm; con  tiempo de desorción de 4 min a 250 °C. El rango lineal de 5-100 mg/L fue establecido con una desviación estándar relativa (%RSD) en el rango 6,1-10,1 %. Los límites de detección estuvieron en el rango 3,8-7,8 mg/L. El promedio de la concentración de THM´s fue de 55,5 mg/L el cual cumple con los límites máximos permitidos en la regulación internacional y nacional.

Published: April 2016

El objetivo de este artículo fue aislar e identificar los microorganismos presentes en los residuos de fruto y  torta de higuerilla. Se utilizaron medios de cultivo selectivos para la caracterización morfológica y bioquímica y para la identificación molecular se usó la técnica de PCR con oligonucleótidos universales RM y RB del gen 16S para bacterias y secuencias intergénicas ITS1 e ITS4 para hongos y levaduras. Las secuencias fueron analizadas identificándose nueve especies de hongos, siendo Penicillium brevicompactu predominante; 12 especies de bacterias, donde el género más recurrente fue y dos especies de levaduras, Rhodosporidium paludigenum y Pichia burtonni. La identificación de la microbiota nativa presente en los residuos de higuerilla es muy promisoria, aportando un amplio conocimiento sobre la versatilidad metabólica de cada una de las cepas aisladas. El mayor número de aislamientos se obtuvieron de la torta probablemente debido al alto contenido de nutrientes presentes en este residuo.
CARACTERIZACIÓN TEXTURAL Y QUÍMICA DE CARBONES ACTIVADOS PREPARADOS A PARTIR DE CUESCO DE PALMA AFRICANA (ELAEIS GUINEENSIS) POR ACTIVACIÓN QUÍMICA CON CaCl2 y MgCl2
Authors: Acevedo Sergio , Giraldo Liliana , Moreno Juan Carlos
Published: April 2016

Se obtuvieron carbones activados mediante activación química de cuesco de palma africana con soluciones de cloruro de magnesio y cloruro de calcio a diferentes concentraciones. Los materiales preparados se caracterizaron textural y químicamente. Los resultados obtenidos muestran que los carbones activados con los mayores valores de área superficial y volumen de poro se obtienen cuando se emplean soluciones con las menores concentraciones del agente activante. Los carbones activados obtenidos presentan áreas superficiales y volúmenes de poro con valores entre 10 y 501 g y 0,01 y 0,29 cm/g respectivamente. Los valores de las entalpías de inmersión de los sólidos en agua se encuentran entre -14,3 y -32,8 J/gy en benceno entre -13,9 y -38,6 J/g. La acidez y la basicidad total de los carbones activados presentan valores entre 23 y 262 µmol/g y 123 y 1724 µmol/g respectivamente. También se determinó el pH en el punto de carga cero, con valores entre 4,08 y 9,92 para el conjunto de los carbones activados. Los resultados muestran que la activación con las sales MgCl y CaCl producen carbones activados con poros en el rango de los mesoporos que facilitan la entrada del adsorbato al interior del material.
As antinomias metaéticas entre cegos e não cegos e o problema do realismo moral
Authors: Peruzzo Júnior Léo
Published: April 2016

O presente artigo apresenta o cognitivismo moral pragmático como forma de superar as antinomias clássicas entre cegos e não-cegos e a (im)possibilidade de representação mental do conteúdo moral. Esta posição é sustentada a partir da reconstrução do debate metaético instaurado entre cognitivistas e não-cognitivistas, especialmente nas interpretações fornecidas pelo realismo moral de McDowell e pelo quase-realismo de Blackburn. Assim, o pressuposto comum a essas duas teorias metaéticas [cognitivismo e não-cognitivismo] pretende ser superado pelo cognitivismo pragmático, uma vez que suas falsas dicotomias partem da tese de que todo conhecimento moral é proposicional. Para sanar esse paradoxo, evitamos uma dicotomia radical entre fatos e valores, isto é, não há ações que podem ser valoradas extrinsecamente ao contexto do seu uso.

Martín Fierro para la niñez argentina: la pedagogía del Gaucho en la escuela primaria
Authors: Casas Matías Emiliano
Published: April 2016

Las recurrentes apelaciones a la función patriótica de las escuelas argentinas establecieron los parámetros que contextualizaron la circulación de la cultura gaucha en las aulas a partir de la década del treinta. En este ensayo, la atención se focaliza en la utilización del Martín Fierro y las adaptaciones operadas sobre las características del personaje original para que resultara “maestro legítimo” de los niños escolares. También se abordan las actividades propuestas a partir de la literatura gauchesca en pos de ejercitar distintos contenidos. Desde las políticas educativas, la figura del gaucho resultaba un recurso fundamental para promover una serie de valores estudiantiles. Ese posicionamiento implicó determinadas reconfiguraciones al gaucho para que el otrora considerado matrero y bandolero sea reconocido ahora como docente moralizador y ejemplo de patriotismo.
Dynamic Systems Theory and Sociocultural Theory
Authors: McCafferty Steven G.
Published: April 2016

Both Dynamic Systems Theory and Sociocultural Theory consider second language development to be complex and dynamic, taking place through change across time. However, each has a different theoretical/methodological perspective, the former focusing on this process primarily as interconnected self-organizing systems and the latter as tied to the psychological development of consciousness as derived through experience across cultural historical contexts of activity. Nonetheless, there are shared elements that deserve recognition and consideration, particularly as regards future research.
Stewart platform pneumatic control system development and characteristic research
Authors: Greshnyakov P. I.
Published: April 2016

The paper presents the results of improving the Stewart platform control system by applying the second-order regulation law to pneumatic drive controllers and transformation of the actuating signal for the functioning of valves in the linear region of the flow characteristic. Methods of mathematical and numerical simulation using the software package MatLab/Simulink and AMESim are used to analyze the sufficiency of the measures proposed. Special attention is given to the analysis of the pneumatic drive dynamic characteristics. Dynamic characteristics of the pneumatic drive control system incorporated in the Stewart platform are calculated, which show the efficiency of the proposed methods of improvement. If the pneumatic drive is used as part of the Stewart platform the load in the output component can reach hundreds of kilograms, which makes it possible to use it both for dynamic tests of the systems and for positioning objects, for instance, mobile simulators.

The study focuses on the effect of breed on the body weights and average daily gains (ADGs) during pre-weaning (birth-4 weeks) and post-weaning (4-16weeks) of Flemish Giant, Californian White and their Crossbreds. The data was subjected to one way analysis of variance. The difference between the means was tested by significance using Duncan’s multiple range test by programming and processing in computer. The overall least squares mean body weights at birth, 1, 2, 3 and 4 weeks of age were 52.38 ± 0.69, 110.58 ± 1.77, 169.97 ± 3.23, 254.35 ± 5.77 and 398.13 ± 8.44g, respectively. The overall least square means for post-weaning body weights at 6, 8, 10, 12, 14 and 16 weeks of age were 620.90 ± 13.11, 862.50 ± 18.10, 1072.88 ± 21.40, 1302.47 ± 24.69, 1535.12 ± 26.90 and 1733.51 ± 29.09g, respectively. The influence of breed was found to be significant on body weights at all the ages except at birth and on ADGs at all ages during pre-weaning and most of the ages during post-weaning. Feed efficiency of Flemish Giant, Californian White and their crossbreds were studied during post weaning period and observed that FCR (kg DMI/ kg gain) were 3.46, 3.99 and 3.86.

A study on breeding and calf rearing management practices of Varanasi district in Uttar Pradesh was carried on by collecting data from 250 dairy farmers of 5 different block viz. Sewapuri, Kashi Vidyapeeth, Arajiline, Rohaniya and Chiriagoan of Varanasi district. The study revealed that almost all the respondents relayed only on symptoms of estrus and particularly mucus discharge alone (33.6%) or in combination of other symptoms of estrus like bellowing (45.2%) and restlessness (21.2%) for heat detection in their animals. Respondents were breeding their animals by AI (26.8%), natural service (26.8%) and by both (46.4%). Mostly (73.2%) respondents mate their animals after 18 hrs of heat detection, while maximum (41.6%) number of respondents bred their animals between 3-5 months after calving. In case of calf rearing management practices, study revealed that 70% of respondents attended their animals during calving, while only 30.4% of respondents practiced ligation, cutting and disinfection of navel cord. Only 32% respondents fed their calves colostrum within 2 hrs of birth. 66.4% of respondents weaned their calves at 3 months of age, rest never weaned their calves. Majority 57.6% of farmers provided calf starter to their calves, while 42.4% didn’t provided calf starter and 68.4% of respondents fed fodder to their calves around 2 months of age. Only 38% respondents were dehorning their calves and 33.2% castrating their male calves in the study area.
Health-Related Quality of Life During the Menopausal Transition: Testing a Theoretical Model
Authors: Shin Hyunjeong , Park Young-Joo
Published: April 2016

The purpose of this study was to test the hypothetical model of health-related quality of life (HRQOL) during the menopausal transition. The model was developed to test specific components of the Wilson and Cleary’s model for HRQOL. A cross-sectional, correlational study was carried out using self-report questionnaires on a convenience sample of 162 Korean women in the menopausal transition. The model was tested by a path analysis using Analysis of Moment Structure (AMOS) program. The path analysis showed that 5 affecting variables explained 69% of the variance in HRQOL during the menopausal transition. Based on the results, the Wilson and Cleary’s model may be useful in explaining HRQOL during the menopausal transition. Symptoms, functional status, and health perceptions mediated the effect of individual and environmental characteristics on HRQOL. However, the results suggest that some paths need to be added or modified in the model. To date, most research using Wilson and Cleary’s model has been conducted in the United States, Africa, and Europe (e.g., Austria, Norway, and Spain). This study shows the applicability of the model in Asian people.
HUBUNGAN HUKUM DAN MORALITAS MENURUT H.L.A HART
Authors: Bello Petrus CKL
Published: April 2016

Hukum positivisme Hart bertujuan mensintesa sikap hukum alam dan hukum moralitas yang memiliki hubungan yang diperlukan dan posisi positivisme hukum klasik dunia yang menganggap bahwa dua kutub yang benar-benar tidak memiliki hubungan. Namun, upaya Hart untuk mendamaikan dua tradisi yang bertentangan tidak bekerja, bukan membuat sistem pemikiran Hart tentang masalah ini tetap ambigu. Di satu sisi, Hart menyatakan bahwa hukum dan moralitas saling terhubung, bahkan sampai ke titik yang hubungan mereka menjadi hubungan alam mutlak, sementara di sisi lain, ia menegaskan bahwa keduanya tidak benar-benar terkait dan harus jelas berdiri terpisah. Hart berpendapat bahwa pemisahan harus dilakukan untuk menghindari konservatisme dan anarkisme. Artikel Ini akan menunjukkan bahwa pandangan Hart adalah keliru dan bahwa argumen untuk memisahkan dua tidaklah cukup. Hukum dan moralitas yang benar-benar menganggap satu sama lain dan pengakuan dari hubungan ini tidak membuat seseorang konservatif atau anarkis.
PENGARUH KONFIGURASI POLITIK TERHADAP PRODUK HUKUM PADA MASA PEMERINTAHAN SOEHARTO DI INDONESIA

Published: April 2016

Pemerintahan Soeharto menjadi sebuah tema menarik bagi hampir setiap penelitian karena keunikan dari pemerintahannya yang dikenal dengan sifat otoriter. Namun, keunikan tersebut hanya diteliti hingga akibat dari otoriternya yang telah menimbulkan kegerahan dari hampir seluruh rakyat dan akhirnya berujung pada berhentinya Soeharto sebagai kepala Negara Indonesia. Padahal dilihat dari kacamata hukum, transisi politik pada masa tersebut tidak hanya berpengaruh secara politik, tetapi juga secara hukum sehingga dapat dibedakan antara pemerintahan yang otoriter dan pemerintahan yang demokratis. Penelitian ini akan membahas permasalahan tersebut yang dibagi atas dua yaitu bagian pertama yang akan melihat konfigurasi politik yang terjadi di Indonesia pada masa transisi dari pemerintahan Soekarno menuju pemerintahan Soeharto, serta bagian kedua yang akan menganalisis bentuk produk hukum yang dibentuk dari konfigurasi politik yang dibangun setelah masa transisi tersebut dibandingkan dengan produk hukum sebelum dan sesudah masa transisi. Dengan dua permasalahan tersebut diharapkan dapat memperlihatkan bagaimana seorang kepala negara memerintah akan mempengaruhi bentuk kebijakan yang diambil yang pastinya akan dituangkan dalam bentuk legislasi. Kesimpulan sementara adalah ada pengaruh yang signifikan antara konfigurasi politik dengan produk hukum yang dihasilkan oleh lembaga legislatif pada masa pemerintahan tersebut.Pemerintahan Soeharto menjadi sebuah tema menarik bagi hampir setiap penelitian karena keunikan dari pemerintahannya yang dikenal dengan sifat otoriter.

Salah satu ide fundamental yang diangkat dalam postmodernisme ialah advokasi keberagaman dan kebebasan tanpa perlu mengikuti adanya bentuk-bentuk tertentu yang dihegemonikan oleh arus pemikiran utama. Postmodernisme, meskipun diawali dari seni dan literatur, berkembang dalam bidang lain termasuk dalam hukum. Pembahasan postmodernisme dalam satu diskursus hukum berusaha, di satu sisi, mempertemukan arus utama dan minoritas secara bersamaan di dalam keserasian, tetapi di sisi lain, adanya tantangan bahwa hukum – khususnya undang-undang – ditetapkan untuk diberlakukan secara seragam. Tulisan ini membahas mengenai perspektif postmodernisme dalam memahami pornografi dalam konteks UU 44/2008 tentang Pornografi; undang-undang ini menyimpan permasalahan yang masih harus diselesaikan oleh aparat penegak hukum. Pertanyaan yang hendak dijawab ialah bagaimana konsep postmodernisme dapat membantu aparat penegak hukum, khususnya hakim dalam membangun parameter rasional intersubjektif untuk menentukan konten pornografi.

Accounting graduates and the capabilities that count: Perceptions of graduates, employers and Accounting academics in four Australian universities
Authors: Oliver Beverley , Whelan Barbara , Hunt Lynne , Hammer Sara
Published: April 2016

The higher education sector in Australia is moving rapidly towards greater accountability in regard to graduate employability outcomes. Currently, data on new graduates' self-reported generic skills and employment status provide the evidence base for universities to make judgements about the effectiveness of curricula in preparing students for employment. This paper discusses alternative sources of evidence, namely the Graduate Employability Indicators (GEI) - a suite of three online surveys designed to supplement current indicators. They are designed to gather and report graduate, employer and course (teaching) team perceptions of the achievement and importance of graduate capabilities within specific degree programs. In 2009 and 2010, the surveys were administered to stakeholder groups associated with Accounting degrees in four Australian universities. In total, 316 graduates, 99 employers and 51 members of the course teaching teams responded to the surveys. This report presents the aggregated results from the trial. These suggest that the fourteen capabilities at the heart of the GEI are considered important, and that both quantitative and qualitative items facilitate the reporting of essential information. Both Accounting employers and teaching staff consider that important capabilities need to be better demonstrated by new graduates. The graduates themselves identified ways in which their courses can be improved to enhance their early professional success. An importance-performance analysis suggests prioritising particular capabilities for immediate attention in particular, work related knowledge and skills, writing clearly and effectively, thinking critically and analytically, solving complex, real-world problems and developing general industry awareness. This paper suggests that an enhanced industry focus might be effected through authentic assessment tasks, and clear identification of the capabilities developed through the curriculum.
Developing Indigenous Australian cultural competence: A model for implementing Indigenous content into curricula
Authors: Flavell Helen , Thackrah Rosalie , Hoffman Julie
Published: April 2016

Cross-cultural understanding has been identified as an important graduate capability crucial for global citizenry, and most universities now include cultural skills or competence within their generic graduate capabilities. However, cross-cultural education and pedagogy are specialised areas and few academics are equipped, or have the confidence, to teach in this area. As a consequence, cross-cultural graduate capabilities are rarely effectively measured or assured. Despite these challenges, the Australian higher education sector is increasingly being called upon to Indigenise its curriculum and develop graduates with Indigenous cultural competence (Australian Universities Guiding Principles for Developing Indigenous Cultural Competency, 2011). This paper describes the approach used to introduce a unit into Curtin University's School of Nursing and Midwifery, in partnership with Curtin's Centre for Aboriginal Studies, with the aim of developing graduate Indigenous Australian cultural competence. Pedagogical approaches are discussed and an analysis of quantitative and qualitative data from the University's online student feedback mechanism provided. Results show that although the unit has provided the majority of students with a strong start on their journey to developing Indigenous cultural competence a single course is not sufficient and, consistent with the literature in the field, resistance to compulsory Indigenous content is evident. The paper considers some of the complexities of teaching Indigenous Australian content within a contemporary Australian university. In doing so, the paper explores what Indigenous cultural competency might be and how it might be achieved providing a useful model with application to other disciplines.
Competing in the graduate labour market: Student perspectives on (not) participating in extra-curricular activities
Authors: Greenbank Paul
Published: April 2016

In order to be able to compete in an increasingly competitive graduate labour market students need to develop their 'personal capital'. Participation in a range of relevant extra-curricular activities (ECAs) is a key element to the development of personal capital. This paper carried out in-depth interviews with undergraduates in the first and final years of their studies in order to understand the factors influencing their level of participation in ECAs. The research found that participation in ECAs was generally limited (with little change occurring during the three years of their degree), particularly in relation year-long work placements, volunteering and sporting and cultural activities. Students often engaged in part-time working, but this was for financial reasons, with few students regarding part-time working as a way of developing their employability. The students underlying values, especially their present-time orientation, and the desire to enjoy a particular student life-style, were acting as barriers to engaging in the type of ECAs that would help them to develop their personal capital. This paper suggests that we may be able to motivate students to participate in ECAs by encouraging them to be future-orientated, less risk averse and willing to adopt a more strategic (i.e. 'player') approach to developing their personal capital. The paper proposes that this can be achieved by encouraging students to write about their future possible selves and asking them to undertake research into the different career options open to them.
Driving institutional engagement in WIL: Enhancing graduate employability
Authors: Ferns Sonia , Lilly Linda
Published: April 2016

Authentic learning experiences that replicate workplace settings are essential elements of the student experience for optimising graduate employability outcomes. Work Integrated Learning (WIL) supports the development of generic attributes which are highly regarded by employers through embedding authentic learning experiences in curricular and co-curricular programs. The regulatory and standards-based environment which monitors and controls higher education institutions' operations is increasingly focussing on WIL and the employability capabilities of graduates. In addition, external stakeholders such as employers and community agencies expect that graduates are prepared for a global and uncertain job market. The ultimate aim is to build a competitive and sustainable Australian economy through ensuring a highly-skilled population. Higher education is considered a key mechanism for achieving this ambition. Reconceptualising curriculum development and assessment strategies is required in order to address these societal demands.

Embedding the development of employability capabilities in curriculum to ensure work-ready graduates is a priority for Curtin University as it aspires to provide authentic learning experiences where students apply theoretical concepts in real-world settings. Scaffolding skill development across curriculum is fundamental to quality curriculum design. Flexible industry and community partnerships are integral to implementing a practice-based curriculum, enabling the development of professional practice to be an integral component of the degree program. This paper presents a three-year Strategic Project, which aimed to enrich the student experience through establishing an institutional framework for WIL, as a case study to inform further WIL initiatives. It outlines strategies implemented to achieve the strategic goals, to introduce innovative approaches for establishing an institutional framework, and to enhance the student experience through WIL.

Published: April 2016

O artigo apresenta os resultados de pesquisa realizada acerca do trabalho em equipe e aprendizagem organizacional. Na pesquisa, o objetivo geral foi o de analisar as estratégias utilizadas pela gestão com pessoas para incentivar o trabalho em equipe, visando alcançar êxito no processo de aprendizagem no contexto organizacional. O artigo busca responder ao seguinte problema: quais estratégias são utilizadas pela gestão com pessoas para incentivar o trabalho em equipe visando êxito na aprendizagem organizacional? Para o desenvolvimento da pesquisa, recorreu-se ao estudo do caso da empresa BETA S/A, do setor siderúrgico, que resolveu implantar o trabalho em equipe. Nesse sentido, houve a oportunidade de pesquisarmos os desdobramento da prática e suas decorrências sob a ótica dos empregados das diversas áreas. Dentro do estudo foram realizadas 39 entrevistas com líderes e subordinados. Quanto aos resultados, inicialmente, verificou-se que apesar da literatura defender um perfil inovador e estratégico para a área de RH, considerando suas transformações para a valorização do profissional como alternativa para alcançar melhores resultados organizacionais, identificamos que a prática do trabalho em equipe carece de aprofundamento no estudo de suas iniciativas e conseqüências, sendo inclusive de difícil aplicação em qualquer organização.

Published: April 2016

A pesquisa tem como objetivo investigar como a população de um assentamento rural do Nordeste trata a questão do resíduo gerado na comunidade. Secundariamente analisa se há conscientização sobre os danos que a queima dos resíduos pode causar ao meio ambiente, aos solos destinados a produção agrícola e a saúde dos assentados. Foram realizadas entrevistas com 54 famílias em sete agrovilas, número determinado por exaustão dos dados e por acessibilidade. Na pesquisa de campo de natureza descritiva e qualitativa, percebeu-se que o poder público não realiza um serviço de coleta de resíduos no assentamento e que os assentados, apesar de serem conscientes dos problemas ocasionados pelas queimadas, ainda assim as realizam. Os assentados afirmam ser essa a única alternativa para o descarte dos resíduos. Considerando os dados foi possível identificar o aproveitamento dos resíduos orgânicos para alimentar os animais, e em alguns casos na utilização para adubo orgânico.

Além disso, foram observados alguns resultados divergentes no que se refere à relação positiva entre Imagem e Brand Equity, e entre Imagem e Fidelidade.
Exercício de desconstrução dos pressupostos conceituais da competitividade organizacional
Authors: Lucena Rosivaldo De Lima , Valadão José de Arimatéia Dias
Published: April 2016

Neste ensaio, intencionamos desconstruir, à luz dos binários competição/cooperação, mercado/sociedade e humanização/desumanização no ambiente de trabalho, alguns pressupostos teóricos do construto competitividade organizacional. Para tanto, lançamos mão de argumentos de autores críticos organizacionais. Constatamos que o referido construto apresenta distorções em seu arcabouço teórico, principalmente se levarmos em conta que os processos de gestão das organizações devem ter como um dos seus objetivos a equidade socioeconômica. Com isso, entendemos que ao supervalorizar a dimensão econômica, a rapidez dos processos, a minimização dos custos, dentre outros fatores, a competitividade acaba por contribuir diretamente para a desumanização no ambiente de trabalho.
A New Approach to Reservoir Characterization Using Deep Learning Neural Networks
Authors: Korjani M. , Popa Andrei , Grijalva Eli , Cassidy Steve , Ershaghi I.
Published: April 2016

Reservoir description and characterization is one of the main/critical engineering components which require a good understanding to ensure the optimum reservoir development that leads to the highest recovery. Reservoir modeling uses all available information which includes at a minimum logs data, and fluid and rock properties. In this study, a deep learning neural network was developed to estimate the petrophysical characteristics required building a full field earth model for a large reservoir. This was accomplished through a learning process whereby the model was presented with diverse and large volumes of log data measured in the field.

The study demonstrates the capability of the deep learning neural network model when tested against the newly drilled wells in the field. The model proved to generate synthetic logs almost identical to those recorded in the new wells. In a future paper, we will demonstrate how the reservoir model constructed using generated data led to significant improvement in the full field reservoir as contrasted to the existing earth model developed using Kriging technology.
Dynamic Considerations for Induced Seismicity
Authors: Walker Robert L. , Aminzadeh Fred
Published: April 2016

Recent interest in induced seismicity that has brought the topic into the spotlight has largely focused on hazards related to fluid injection. While drawing needed attention to an important topic, such focus may lead to a simplistic treatment of the entire process relating to induced seismic hazard. The challenge is as complex as it is poorly understood, and while it is true that fluid injection and earthquakes seem to appear in tandem, one cannot automatically assume that the problem can be described with only one variable.

In this work, we consider the impact that dynamic influences such as transient stresses from passing seismic waves can impart on a fault at risk for failure. Review of geophysical literature reveals a rich foundation based in a strong respect scientific inquiry, often in stark contrast to meager data available. Beginning from an initial consideration of effects from transient dynamic stresses, it soon becomes apparent that not only is permeability affected by transient seismic stresses, but that the permeability itself behaves dynamically. We find that past literature on dynamic permeability contains useful insight, however the focus of previous work proves divergent from those of the Petroleum Industry, and prior investigation remains unsatisfactory. Additionally, review of data resources available for areas of the mid-continental United States subject to increased seismic activity suggest that an excellent, and as of yet unused, data set for the study of dynamic permeability may have been generated. Observational data suggests that in the wake of seismic activity, permeability must be considered as a dynamic value.
A Simple Method for the Removal of Tidal Effects in Pressure Transient Analysis
Authors: Acuna Jorge A.
Published: April 2016

This paper presents a simple method for the removal of tidal effects based on analysis of the primary derivative of pressure. The method consists of isolating the oscillating component of the primary derivative caused by tidal effects. This is possible because the primary derivative of the reservoir component approaches zero with time while that of the tidal component persists due to its oscillatory nature. The isolated derivative of the tidal component of pressure can be fitted to a reference tidal signal or a combination of harmonic functions. Once this is done, the derivative tidal component function can be filtered out from the pressure derivative and pressure signals for transient analysis.

The method is validated by analysis of synthetic data where a sinusoidal signal is added to a test and the method is used to extract it from the combined signal and then compared to the input signal. Application of the method to an actual well test is also presented. This approach can be used to complement other published methods referenced in the paper, but contrary to those, it does not require to guess the shape of the reservoir pressure component before removal of the tidal component.
Wettability Alteration in Reservoirs: How it Applies to Alaskan Oil Production
Authors: Thyne Geoffrey
Published: April 2016

The natural decline in oil production in Alaskan reservoirs is challenging producers to find methods to extend production. The current stage of reservoir development has reached the point where consideration of enhanced oil recovery methods is appropriate. Such methods could include CO2, chemical, microbial or thermal recovery. However, these methods require significant capital and/or operational investment. This paper evaluates the application of wettability alteration for Alaskan reservoirs by changing injection water chemistry also known as advanced water flooding. We use empirically-based screening and scoping methodologies to evaluate the suitability, cost and benefits of advanced water flooding for Alaskan reservoirs using public domain data.

First, laboratory and field examples of successes and failures are considered. Using this basis, a theory is developed that directly links water chemistry and reservoir wettability. The theory also illuminates the key characteristics of the reservoir that control wettability. We use empirically-based screening and scoping methodologies to evaluate the suitability, cost and benefits of advanced water flooding for Alaskan reservoirs with sufficient public domain data. The screening tool is built on empirical data from laboratory and field tests that identify the critical factors contributing to incremental production. The scoping tool uses a modified Kinder Morgan approach (dimensionless recovery curve) to evaluate the economic case for each reservoir.

The first field-scale tests of this technique were conducted by BP in the Endicott reservoir on the North Slope and produced good results by lowering the salinity of injection water. Those tests showed that alteration to injection water chemistry can increase recovery significantly. These results have been duplicated in laboratory and field tests in other locations. The tests were conducted without an understanding of the fundamental mechanisms nor optimization of the injected water chemistry, and thus represent minimum recovery. We find the increased recovery is profitable for several fields depending on assumptions about water sources, water treatment costs and rates of injection.

The successful approach to advanced waterflooding requires several key steps: screening the formation to evaluate the applicability of the technique, simple laboratory tests to determine the optimal water chemistry and quantify the increased recovery, economic evaluations to estimate costs and benefits, and finally, comprehensive geochemical models to design the wettability-modifying fluids. The technique has several advantages compared to current methodologies for wettability alteration including substantially lower costs, no environmental impacts and ease of application.

The recovery of oil from carbonate reservoirs is usually low due to their extreme heterogeneity caused by natural fractures and the nature of the oil-wet matrix. Low salinity water flooding (LSWF) and preformed particle gels (PPGs) control conformance are two novel technologies that have recently drawn great interest by the oil industry. We developed a cost- effective, novel, enhanced oil recovery (EOR) technology for carbonate reservoirs by coupling the two technologies into one process. The objective of this paper is to provide a comprehensive understanding of the combined technology and to test through laboratory experiments the extent to which the coupling method can improve oil recovery. The laboratory experiments showed that the optimum water salinity for the application of the coupled method was 0.1 wt. % NaCl under experimental conditions. The water residual resistance factor (Frrw) increased as the water salinity and the fracture width decreased. The oil- wet carbonate cores provided a higher improved oil recovery than a water-wet carbonate cores during LSWF. The decrease in fracture width resulted in a higher oil recovery factor. Compared to traditional bulk gel treatments, PPG forms stronger plugging but will not form an impermeable cake in the fracture surface; therefore, PPG allows low salinity water to penetrate into the matrix to modify its wettability, thus producing more oil from the matrix. Results also show that oil recovery increased by 10 % during LSWF after the second waterflooding. Additionally, when PPG was injected, another 8 % of oil recovery was gained. As a result, combined the LSWF and PPG increased oil recovery by 18%. LSWF can increase only displacement efficiency but has little or no effect on sweep efficiency, while particle gels can plug fractures or in high-permeable channels to improve sweep efficiency but have little effect on displacement efficiency. The coupled method bypasses the limitations of each method when used individually and improve both the displacement and the sweep efficiency.

Comprehensively understanding the gas hydrate accumulation mechanism is significant for the investigation of subsea gas hydrate reservoir which can provide further guidance for the hydrae exploration and development as well as the safe deep-water drilling. In this paper, a preliminary conceptual model is established to study the characteristics of gas hydrate accumulation in the typical shallow formation under the sea using a reservoir simulation method. A partial equilibrium reaction model based on the phase equilibrium of gas hydrate is used to describe the trigger mechanism of hydrate formation when methane from deep formation migrates into the upper hydrate stability zone under the seabed. Two cases are simulated for comparison, one considering the barrier effect of cap rock at seabed while the other assuming a cold spring at seabed. The simulation results indicate that in the cap rock case, a thick hydrate layer tends to be formed in the upper subsea formation but with a relatively smaller hydrate saturation, while in the case of cold spring, nearly 90% of methane from deep reservoir would leak into the sea water, nevertheless the long-term slowly gas driving water process is favorable for generating high hydrate saturation. Generally, low flux of methane gas, cap rock barrier, deep water depth, and small geothermal gradient below mud line are beneficial to forming valuable hydrate reservoirs with larger thickness and high abundance. This study has proven that the reservoir simulation method can be an effective tool to simulate the process of gas hydrate formation and accumulation in the shallow formation under the sea, which deserves for further study.
Integrating Enhanced Oil Recovery and Carbon Capture and Storage Projects: A Case Study at Farnsworth Field, Texas

Published: April 2016

The Southwest Partnership on Carbon Sequestration (SWP) is one of seven large-scale demonstration projects sponsored by the U.S. Department of Energy. The SWP has a goal of permanently sequestering more than 1,000,000 metric tonnes of CO2 in an active EOR project in a mature waterflood in the Anadarko basin. The CO2 for this project is anthropogenically sourced from a fertilizer and an ethanol plant. As of the end of 2015 the field has 13 CO2 injectors and has sequestered 386,695 metric tonnes of CO2 between October 2013 and July of 2015. Goals of the project include optimizing the EOR/storage balance, ensuring storage permanence, and developing best practices for carbon storage utilizing man-made CO2.

The field site provides an excellent laboratory for testing a range of monitoring technologies in an operating CO2 flood since field development is sequential and allows for multiple opportunities to record zero CO2 baseline data, midflood data, and data from fully flooded patterns. The project has acquired data at a number of scales including a 42 mi2 3D seismic survey, baseline and repeat 3D VSP surveys centered on three injection wells, cross-well tomography baseline and repeat surveys between injector/producer pairs, a borehole passive seismic array to monitor for induced seismicity, a distributed temperature system, and bottomhole pressure and temperature sensors. The project has drilled three wells in the field, and has acquired over 750 ft of core in the Morrow B reservoir interval and associated caprock units. Additional monitoring focuses on CO2 soil flux, groundwater chemistry, reservoir fluids chemistry, and aqueous and gas-phase tracer studies.

All acquired data have contributed to detailed geologic models used for fluid flow and risk assessment simulations. 3D VSP and cross-well data with repeat surveys have allowed for direct comparisons of the reservoir prior to CO2 injection and at eight months into injection, with a goal of imaging the CO2 as it moves away from injection wells. Additional repeat surveys at regular intervals will continue to refine direct CO2 imaging as production and injection data are integrated with newly acquired and interpreted data. All models are regularly updated. In this paper the project goals will be outlined, progress towards goals enumerated, and current geologic and simulation models will be introduced. In addition, initial results from time-lapse monitoring of movement of CO2 in the reservoir will be discussed.
