espanolEl articulo explora la cuestion del desarrollo productivo en zonas rurales a partir de un abordaje a la situacion del periurbano de la ciudad de Parana, Entre Rios. Se focaliza en las pequenas explotaciones agricolas, revisando la asociatividad como principal componente de los entramados de productores. A partir de esto plantea que es posible establecer Sistemas Productivos Locales que vinculen, a traves de la Economia Social y Solidaria, a los pequenos productores y otros actores de los entramados agroalimentarios. Propone a los agricultores familiares como actores clave del sistema, incorpora la puja entre el modelo agroecologico y el extractivista, y expone la tension que se genera alrededor de la Soberania Alimentaria al presentarla como un objetivo politico en sintonia con el Desarrollo Territorial. EnglishThe article explores the question of productive development in rural areas from an approach to the peri-urban situation of the city of Parana, Entre Rios. It focuses on small agricultural holdings, reviewing associativity as the main component of producer networks. Based on this, suggests that it is possible to establish Local Productive Systems that link, through the Social and Solidarity Economy, small producers and other actors of the agri-food networks. It proposes family farmers as key actors in the system, incorporates the struggle between the agroecological and extractive models, and exposes the tension that is generated around Food Sovereignty by presenting it as a political objective in tune with Territorial Development.

132 p. La investigación que se está llevando a cabo, tiene el propósito de describir los principales retos pedagógicos, didácticos y tecnológicos que impuso la realidad del Covid-19 a los docentes de la Institución Educativa Cecilia de Lleras, en Montería, Colombia; ésta se desarrolla mediante una investigación por la aplicación de un enfoque metodológico de carácter mixto, de tipo descriptivo con diseño contemporáneo. La población la conforman los docentes de básica secundaria de la Institución Educativa Cecilia de Lleras, en Montería, Colombia y algunos directivos de la misma. Para la recolección de los datos se emplearon técnicas como encuesta mediante el cuestionario, la entrevista semiestructurada usando la guía de entrevista, el análisis documental y el grupo de discusión llevando a cabo un foro en línea. Para el análisis de resultados se realizó mediante la triangulación de resultados a partir de análisis de datos cuantitativos gráficos y tablas; y los datos cualitativos mediante matriz de información. Los resultados indican que los docentes y las Instituciones no se encuentran debidamente preparados para la educación virtual que se impone como único medio para continuar en la crisis sanitaria por Covid-19, porque su formación se enfoca en la educación presencial tradicional, y en pocos casos se aborda la virtualidad en el desarrollo de las clases, a pesar de que las herramientas TIC se impulsen desde el Ministerio de Educación. The research being carried out, aims to describe the main pedagogical, didactic and technological challenges imposed by the reality of the Covid-19 to the teachers of the Cecilia de Lleras Educational Institution school, in Monteria, Colombia; This is carried out through an investigation by the application of a methodological approach of mixed character, of descriptive type with contemporary design. The population is made up of secondary school teachers from the Cecilia de Lleras Educational Institution in Monteria, Colombia, and some of its directors. Data collection techniques such as a questionnaire survey, a semi-structured interview using the interview guide, documentary analysis and a discussion group conducted an online forum were used. For the analysis of results, it was done by triangulation of results from analysis of quantitative data graphs and tables; and qualitative data through information matrix. The results indicate that teachers and institutions are not adequately prepared for the virtual education that is imposed as the only means to continue in the health crisis by Covid-19, because their training focuses on traditional face-to-face education, and in few cases it addresses the virtuality in the development of classes, despite the fact that ICT tools are promoted from the Ministry of Education.

68 p. El presente trabajo realizó el estudio estructural de un edificio realizado en mampostería sin confinar, tomándose la Escuela “Dr. Benjamín Zorrilla” ubicada en calle 20 de febrero N° 47, de la ciudad de Salta como ejemplo de esta tipología. Dicho edificio forma parte del patrimonio histórico de esta ciudad y debido a ello, es de enorme importancia su preservación y conservación. Se analizó el mismo tanto por los métodos estático y dinámico, mediante el empleo de programas de análisis estructural basados en el Método de Elementos Finitos (SAP2000, ETABS) y modelado (Revit y AutoCAD), con las especificaciones de las normas INPRES- CIRSOC 103 y CIRSOC 501. Se aplicó también el Método de Macroelementos, de creciente uso para el análisis sismorresistente de este tipo de estructuras. Se buscó reflejar el desempeño de la estructura ante un evento sísmico intenso, de aceleración máxima igual a la aceleración de suelo sugerida por la norma INPRES-CIRSOC 103, para Zona 3 y suelos Sc y Sd. Los resultados muestran que al menos en este caso, el método de macroelementos es un buen indicador del modo de falla de la estructura. Por otro lado, en los análisis dinámicos la resistencia de la mampostería a tracción y compresión no fue sobrepasada. Fil: Orosco Segura, Lia Elizabeth. Universidad Católica de Salta.

A mature offshore field in Malaysia consists of wells that are over 20 years old and completed with dual-strings and multiple packers to produce from different sand layers. Due to the unconsolidated formation, most of the wells were completed with a gravel pack. After many years of production, the water cut has increased and fines migration has gradually plugged the gravel packs and screens. This has resulted in closing in these wells, leaving stranded potential oil behind. Continuing to produce through the plugged screens would require higher drawdown, which in turn induces greater sanding from the nearby reservoir rock and higher water cut. However, working over these wells was often noneconomical. Initially, several wells were treated with acid but were reported to produce sand after the treatment. This was attributed to screen damage and gravel-pack failure requiring costly repair. Additionally, the acid used to remove the plugging caused by the fines migration weakened the matrix, increasing the sanding tendency. This paper presents a case history of propellent stimulation treatment performed in two wells at this field. The gravel-packed wells were rejuvenated by applying a propellent treatment instead of acid treatments to clean the plugging in the gravel packs and screens over selected intervals that are known to be oil-bearing. Zones that could be producing water because of movement of the oil/water-contact can be left untreated so that the plugging in the screens helps in delaying water production. Propellant has been used in the oil industry for many years, but its application has been mainly for minifracturing of consolidated rock in standard cased and perforated wells. Its application to clean gravel pack is not well known and knowledge in this domain is limited. As such, the case study started with candidate selection and proceeded through the proposed solution, conceptual job design, execution, and finally the results of the application.

Brownfields are often characterized by a varying degree of maturity, both within the field and within individual reservoir units. This variation makes infill drilling more prospective in areas with fewer well penetrations and completions and less production. However, these areas are inherently more uncertain, with geological, petrophysical, and structural parameters particularly affected. A novel workflow solves the complex problem of uncertainty assessment and risk management in a brownfield redevelopment. Traditionally, a single deterministic reservoir model is built, matched, and used for predictions and infill planning. The availability of sophisticated simulation workflow tools enable the team now to explore the practical aspects of performing sophisticated reservoir description, static model construction, history matching, and forecast uncertainty analysis. Incorporated into multiple equiprobable reservoir descriptions, uncertainties are carried from the static model construction throughout the entire dynamic modeling process. History matching is conducted for all realizations, and the match quality is assessed by means of statistical analysis. The workflow facilitates generating hydrocarbon thickness maps by using the average column thickness of many simulation models instead of a dedicated single one. Target selection also accounts for possible sweep and sand risks by means of maps showing the standard deviation of the column thickness. The new framework is applied to a conceptual redevelopment of a brownfield. It increases the understanding of fluid flow processes in the reservoirs and is a vital component of the decision and risk analysis for the concept selection stage.
