Abstract
Be it electrical signals in resistivity logs, radioactivity in gamma ray logs or magnetic moments of hydrogen protons in NMR logs, most logging techniques use an indirect approach to estimate permeability, which, in simple terms, is the measure of the ease with which a fluid of given viscosity can flow through porous media. These logging techniques are often expensive, requiring downhole equipment and, at times, other complimentary logs to obtain the permeability profile. In this paper, we propose and demonstrate a cost-effective, injection-based logging technique to obtain a continuous injectivity and permeability profile. This technique does not require any downhole equipment. Accurate flowmeters and pressure sensors at the wellhead are sufficient.
An in-situ pilot test was performed in a tight overburden formation. The in-situ test data gave clear indications of permeable zones and were found to be in good agreement with the NMR derived permeability log calibrated on core data. We also present interpretation techniques to interpret the data from the injection-based log tests and obtain a continuous permeability profile of the near-well zone. This interpretation technique uses an exact solution to the unsteady flow problem, obtained using ‘Bessel-Fourier’ series. A demonstration of this log test, in a laboratory model that is representative of a multilayer formation, is presented. The test results correctly showed the presence of permeable layers and were interpreted for permeability. Permeabilities thus obtained displayed a strong correlation to the benchmark permeability values of the samples.

Abstract
Inflow Control Devices (ICDs) modify the inflow profile of a multi-zone well completion. Their imposition of an extra pressure drop at the sandface has proven to be particularly effective at delaying the breakthrough of (unwanted) water or gas in wells with long completion lengths. It is widely accepted that an ICD completion improves the field's economics; but the question of whether and why an ICD completion affects the accuracy of standard Pressure Transient Analysis (PTA) workflows has not been addressed.
A typical ICD completion is designed to create an extra pressure drop of a similar magnitude to the well's expected reservoir drawdown when producing at its target rate. This paper shows why this extra pressure drop cannot always be treated as an additional skin value during PTA. This is because the ICD's pressure drop is a time dependent variable, varying with both fluid's viscosity and flowrate through the device. A nonlinear pressure loss can, sometimes, distort the pressure response and render conventional PTA methods inaccurate.
The study presented in this paper uses an integrated, dynamically coupled, wellbore and reservoir model to define the limits within which treating the ICD pressure drop as an additional skin is a valid assumption and when its nonlinear nature will result in an inaccurately estimated value of skin and reservoir permeability. A general workflow for the analysis of PTA data measured in liquid producing wells completed with ICDs is proposed for the derivation of realistic values of the formation damage skin. The workflow has also been adapted for routine monitoring of wells completed with ICDs.
The value of this study is illustrated by its application to two data sets from the North Sea's Golden Eagle field. This is an ideal field to test the validity of our theoretical analysis due to well completions with multiple levels of inflow control together with "state-of-the-art", downhole sensors. The results of this work allows Reservoir and Production Engineers to differentiate between deteriorating well performance due to increasing watercut and that due to an increasing formation damage skin.
Simulation of the Effect of Non-Uniform Proppant Distribution on Well Productivity in Shale Gas Reservoirs

Published: March 2017

Abstract
Uniform proppant distribution in multiple perforation clusters plays a crucial role on sufficiently propping fractures conductivity in hydraulic fracturing. These propped fractures and their effectiveness is critically influenced by the in situ stress in the formation. As great uncertainty exists in uneven propped fracture, this paper examines the impact of proppant distribution and fracture conductivity variation on the gas productivity for shale gas reservoirs, by developing a reservoir simulation model.
In this paper, numerical reservoir simulation, which involves application of a constantly decreasing permeability to the propped fracture, are used to model the uneven proppant distribution and geomechanics effect. The decrease of permeability, along from the wellbore toward the tip, is simulated using an exponential approach, as well as a linear approach. Moreover, Effects of gas desorption and stress-dependent fracture conductivity are taken into account in this model. Sensitivity analysis is carried out on critical parameters to quantify the key parameters affecting gas productivity between uniform and nonuniform proppant distribution. The degree of non-uniform proppant distribution is also investigated and divided into four types of proppant distribution scenarios.
The following conclusions can be obtained based on the simulation results. A big difference on well performance between the case of linear and exponential permeability degradation is observed. The pressure distribution comparison shows higher pressure drops in the exponentially decreasing permeability case, which results in a lower gas production. Reservoir permeability plays a critical role in cumulative gas production, no matter in case of permeability exponentially degrading or linear degrading, followed by fracture half-length, primary fracture conductivity, Fracture complexity, permeability anisotropy. Furthermore, the effect of uneven proppant distribution between different clusters can significantly reduce the gas recovery, especially in low proppant concentration and small fracture conductivity.
The model presented in this paper takes the uneven proppant distribution and geomechanics effect into consideration and shows good agreement with real field production. This paper can demonstrate its own merits on the optimization of hydraulic fracturing treatments, and provide a better understanding of the effect of proppant distribution on well performance.
AIDEZ LES MISANTHROPES
Authors: Kaulingfreks Ruud 
Published: March 2017

In this paper I want to explore into the dark side of art. There has been a growing interest in art from the field of organization studies. Since the publication of Strati’s seminal work (1999) organization studies have embraced art as a fruitful way of studying organizations. Aesthetics helps us to critically understand organizations and uncovers aspects of organization that till now we have overseen. Organizations have an aesthetic quality where sensibility and emotions play an important role. Although I am in no way opposed to an aesthetic study of organizations. I want to argue that when dealing with art we have to consider the dark side of art. Art is in no way something just related to beauty and sensible wellbeing. Organization aesthetics needs to be careful not to fall into a romantic conception of art as a transcendental field enriching our lives, filling us with joy and giving us insight in life. Art also has a dark side. It disorients us, makes us uneasy. Art can make us very gloomy and take away joy. Art shows us a side of life that has by no means moral richness and does not contribute to joy and happiness. After going into the disturbing aspects of art I will examine misanthropy in art and point out some consequences for organizations and organization studies.

LOS RETOS DE LA COORDINACIÓN INSTITUCIONAL PARA EL DESARROLLO REGIONAL EN MÉXICO
Authors: Tapia Mónica 
Published: March 2017

INTRODUCCIÓN
Las estrategias actuales para promover desarrollo enfatizan la dimensión local y el enfoque de actuación sobre el territorio. Se han hecho numerosas referencias también a la necesidad de coordinar actores y de pensar de manera transversal en la planeación tradicional entre sectores. Se trata de aspirar a construir una dinámica verdaderamente federalista, donde las regiones y los estados sean el motor del desarrollo, sin caer en la fragmentación y el regionalismo sino en mecanismos de diálogo, concurrencia y cooperación entre niveles de gobierno. Sin embargo, la compleja realidad del país, con sus contrastantes regiones, procesos políticos y limitantes institucionales, han hecho difícil llevar a cabo estas prescripciones de políticas del desarrollo....
SUJECIÓN LABORAL Y CONFLICTOS JURISDICCIONALES EN UNA COMUNIDAD MAM DEL ALTIPLANO GUATEMALTECO (1890-1947)
Authors: Torras Conangla Rosa 
Published: March 2017

La entrada de Guatemala en la economía de agroexportación cafetalera en el siglo XIX supuso la aplicación de diversos mecanismos de sujeción laboral destinados a movilizar a los trabajadores —sobre todo indígenas— de las zonas donde residían a aquellas donde se producía el cultivo. Las fincas de mozos fueron uno de esos mecanismos. El presente artículo explora los efectos de estas políticas en una comunidad mam del altiplano huehueteco, mismas que provocaron altos índices de conflictividad expresados en desmembramientos territoriales y conflictos jurisdiccionales.
DE LA “CASA” A LA “HACIENDA”. DE VERA (NAVARRA) A CHIAPAS (1750-1821) LAS CARAS JERARQUIZADAS DE UNA PRÁCTICA SOCIAL ESTAMENTAL: LA “OECONOMÍA”
Authors: Urrutikoetxea Lizarraga José 
Published: March 2017

Las líneas que siguen son el fruto de una dinámica en la que el autor de la tesis doctoral que da pie a esta reflexión y quienes le hemos acompañado en la dirección del trabajo hemos tenido la oportunidad de caminar codo con codo a lo largo de una experiencia por descubrir el sentido de los pasos seguidos por una familia que, nacida en un valle húmedo del País Vasco-Navarro —Vera del Bidasoa—, se traslada a América para asentarse definitivamente en tierras chiapanecas.
La historia de los Esponda Olaechea, la experiencia de los emigrantes vasco-navarros en América, recibe así luz desde las dos orillas de una historia compleja, dinámica y dialécticamente jerarquizada. No suele ser habitual poder contar con esta doble perspectiva. Quiero creer que sí ha sido posible en el caso presente. De haberlo conseguido, habrá ganado la historiografía chiapaneca y de hecho, en la misma medida, la historiografía vasco-navarra.

LA NOCIÓN DE PERSONA ENTRE LOS MAYAS: UNA VISIÓN SEMÁNTICA
Authors: Bourdin Gabriel Luis 
Published: March 2017

El presente trabajo está dedicado a las representaciones culturales de la persona entre los mayas yucatecos. Se enfoca la noción de persona partiendo de las categorías conceptuales contenidas en el vocabulario. Se intenta dar una visión semántica de la categoría de persona, atendiendo al significado de las palabras empleadas para identificar los diversos componentes del ser humano individual. Se identifican algunos de los conceptos fundamentales referidos a los diversos componentes que integran el ser humano en la concepción de esta cultura. Entre los mayas peninsulares modernos, el individuo humano se concibe como una unidad de wiinkilil“cuerpo”, pixan “alma” y ool “ánimo”; esta concepción difiere en alguna medida de la que se infiere a partir de los testimonios en maya colonial, y también de las de otros pueblos hablantes de lenguas mayances, entre otras cosas por la ausencia entre los mayas peninsulares de la idea de un “doble animal” asociado de modo íntimo con la vida del individuo.

ABSTRACT
The present paper studies cultural representations of person among Yucatec Mayas. The study is focussed on the notion of person starting from the conceptual characteristics contained in the vocabulary. The paper attempts to give a semantic point of view of the category of person, considering the meaning of the words used to identify the different components of the human being taken as an individual. Some of the essential concepts that refer to the diverse components of the individual human being are identified here. Among the modern Peninsular Mayas, the human being is conceived as a unit of wíinkilil –body–, pixán –soul–, and óol –spirit. This conception somewhat differs from the idea that has been transmitted by Colonial Maya testimonies and by other people speaking Mayan languages. Among other things, this happens because of the absence, among Peninsular Mayas, of an “animal companion”, idea which is closely related to the individual’s life.
LA NOCIÓN DE PERSONA Y EL CONCEPTO DE IXTLAMATKI EN LA VISIÓN DEL MUNDO DE LOS NAHUAS DE LA SIERRA NEGRA DE PUEBLA
Authors: Romero Laura 
Published: March 2017

En la cosmovisión de los nahuas de San Sebastián Tlacotepec, municipio perteneciente a la Sierra Negra de Puebla, la noción de persona es uno de los ejes vertebrales para entender la forma en que es concebido elixtlamatki, el que sabe ver, especialista ritual encargado de los problemas de salud originados por la pérdida del alma, el daño al animal compañero y la brujería.
A partir del análisis de los atributos otorgados al ixtlamatki, mismos que lo definen como un ser humano “especial”, podemos entender su función como intermediario entre el mundo humano y el “mundo-otro”, sus capacidades como “recuperador” de almas, su capacidad de transformarse en animal, la fortaleza de sus entidades anímicas y su facultad de actuar a voluntad durante sus sueños.

ABSTRACT
In the world view of the nahua population of San Sebastian Tlacotepec, a village localized in the region denominated Sierra Negra in the state of Puebla, the “notion of person” is one of the principals elements necessary to understand the concept of ixtlamatki, “ the one who knows how to see”, ritual specialist in charge of health problems en cases like loss of soul, witchcraft or when the alter ego has been hurt.
Beginning with the analysis of his attributes, which define him as special human being, we come closer to understand his function as intermediary between the human world and the “other world”; his power as “soul retriever” and other special abilities, for example, his capacity of transforming himself as well as his faculty to act intentionally in his dreams.
EL HETSMEK' COMO EXPRESIÓN SIMBÓLICA DE LA CONSTRUCCIÓN DE LOS NIÑOS MAYAS YUCATECOS COMO PERSONAS
Authors: Cervera Montejano María Dolores 
Published: March 2017

A partir de la relación entre cosmovisión y etnoteorías parentales y su expresión en prácticas de crianza infantil me he aproximado a la construcción de la persona en los primeros años de vida entre los mayas de Yucatán. Centro este trabajo en la ceremonia de hetsmek’, ya que sugiero puede verse como expresión del papel que juegan las entidades anímicas y la agencia humana en las etnoteorías parentales, al tomar en cuenta la conformación de los niños. Los padres, apoyados en los padrinos, contribuyen simbólicamente a abrirle el camino al infante para que desarrolle las capacidades que definirán su entendimiento. En conjunto evocan las que caracterizan a los seres de maíz en el génesis maya. En particular, la responsabilidad y la adquisición de conciencia se relacionan con ik’, atributo que permite al individuo relacionarse con el mundo al igual que ool y cuyos significados múltiples y relaciones requieren mayor investigación para entender la construcción de la persona entre los mayas de Yucatán.

ABSTRACT
I approach the cultural construction of the idea of person in the first years of life among the Yucatec Maya through the relationship between parental ethnotheories and worldview. I focus in the hetsmek’ ceremony and suggest that it may be seen as the expression in parental ethnotheories of the role played by souls and human society in the formation of children. Parents and godparents symbolically contribute to open the infant’s road in order to develop the abilities that will define the concept of understanding. These evoke the characteristics of human beings modeled from corn as described in the Maya genesis. Among them, responsibility and awareness relate toik’. Together with ool, they refer to the attributes that allow the individual to engage in the world and which require further investigation into their multiple meanings and relations if we are to better understand the construction of the person among the Maya of Yucatan.
HOW DID THE GARIFUNA BECOME AN INDIGENOUS PEOPLE? - RECONSTRUCTING THE CULTURAL PERSONA OF AN AFRICAN-NATIVE AMERICAN PEOPLE IN CENTRAL AMERICA
Authors: Palacio Joseph 
Published: March 2017

¿Cómo fue que los Garifuna adquirieron el estatus de indígenas? Reconstrucción de la persona cultural de los nativos de Centroamérica.
El título del artículo aquí presentado pretende llamar la atención al relativo reciente origen la nomenclatura “indígena” en referencia a nativos del Nuevo Mundo. Los Garifuna –grupo indígena conformado a partir dela mezcla entre nativos americanos, africanos y el carácter bio-cultural legado por los europeos – constituyen un tópico adecuado para el estudio de la formación y retención de la identidad cultural en la revoltura caribeña. Esta presentación inicia destacando la formación de la matriz cultural en el tiempo y el espacio dentro de un contexto en el que la sabiduría convencional que detentaban los pueblos originarios fue exterminada. Continua, haciendo referencia a la creación de oportunidades por parte de los Garifuna para consolidar su identidad en el Caribe oriental a partir de la segunda mitad del siglo XIX, en que se suscitaron décadas de conflicto armado impuesto sobre ellos por los británicos. Termina, con citas de ejemplos de vida del mismo autor relativas a su activismo en los ámbitos académico y movimiento popular indígena en Belice, su país de origen, desde el inicio de la década de 1970.

ABSTRACT
The title of this presentation draws attention to the relatively recent origins of the ‘indigenous’ nomenclature to the persona of indigenous peoples in the New World. The Garifuna – an indigenous people formed from the blending of Native American, African, and European bio-cultural traits – are an appropriate topic for the study of the formation and retention of cultural identity within the Caribbean Basin. This presentation starts with the formation of their cultural matrix over time and space within a context, where conventional wisdom held that all native peoples had been exterminated. It continues with the Garifuna creating opportunities for the consolidation of their identity in the Eastern Caribbean during the latter of half of the nineteenth century, within decades of armed conflict imposed on them by the British. It ends by the author citing examples from his own involvement in academic and popular activism within the indigenous people movement in his home country Belize since the early 1970s.
