Abstract
Production profile logging is an efficient method for production dynamic monitoring and post-fracture effect evaluation in shale gas plays, the method can realize the rule of gas production and water flowback and understand the downhole production situation, it is important to optimize well trajectory, well completion and gas production system. However, the fluids in downhole are mix phases usually, they are composed by gas and hydraulic fraturing fluids in the process of gas production, the flow regimes and status are complicated in horizontal well, in addition, the flow regimes are affected by well diameter and well inclination, thereby, the method of logging data interpretation becomes far more difficult.
This paper researched the interpretation method of production logging data firstly in horizontal well, analyzed the production rate distribution in each fracture in a shale gas well. Subsequently, the paper investigated the fluid phase and flow regimes with the image function of array holdup tools, the water recirculation happened in the stage of dogleg postion. In addition, the paper built the sensivity analysis of openhole logging data and hydraulic fracturing parameters with production logging results, analyzed the main impact fators of gas production contribution in the well. At last, Models with non-uniform fracture properties are built to take into the consideration of production logging results, production rate and estimated ultimate recovery (EUR) are predicted by the models with uniform fractures and non-uniform fractures for the case well.
From the analysis results of production logging data, it illustrated that only about one third to one half of hydraulic fractures had produced gas. Meanwhile, the productive fractures contribute differently to the gas production rate. There was a lot of water in the wellbore acoording to the dynamic leve of the water. The sensitivity analysis indicated the geology properties and hydraulic fracturing parameters are not main impact factors of gas production distribution unevenly in the well. In addition, models with non-uniform fractures and with uniform fracture are built for this case well. Both models can get satisfying log-log plot and history match. Gas rate and pressure transient analysis with non-uniform fractures model gets higher estimated ultimate recovery (EUR) than the one with uniform fractures model.
Through the analysis and application of production profile logging data, understanding the gas flow state in shale gas well, improving the application level of logging data, and the researched results can provide the reasonable suggestions for afterward well trajectory, well completion and produciton optimazition.

Abstract
Performance monitoring and production allocation rely on test separator measurements operating at varying pressure and temperature during periodic tests. Converting test separator gas and oil rates to a common set of separator conditions is necessary to ensure consistent rate allocation and valid inflow performance relations. This paper applies a well test conversion methodology to all historical well test measurements performed on gas condensate reservoirs in the Nile Delta Complex and explores the benefits of such an approach. The studied asset includes seven reservoirs with producing condensate-gas ratio (CGR) varying from 3 to 70 stb/MMscf.
The proposed method converts the reported test rates into molar compositional wellstream rates, using (1) an appropriate EOS model, (2) a reasonable seed composition and (3) the test separator conditions. The seed composition is flashed at separator conditions. Equilibrium oil and gas compositions are then recombined in a specific ratio that yields exactly the test CGR. The obtained compositional wellstream is then re-processed (1) using a common set of separator conditions and (2) using the actual field-scale surface process model. The paper also discusses appropriate choices for the seed composition.
The procedure is implemented and fully automated using a commercial IAM platform. Results show that the separator conditions have a great influence (up to 50 %) on the CGR. We reprocessed the compositional wellstreams using a common set of conditions to compare individual well performance and fluid properties (1) over time and (2) against other wells for a given date. Furthermore, the proposed procedure enables the allocation of final-sales products to individual wells (gas, LPG and stabilized condensate).

Abstract
Sand production is an important issue that occurs in the petroleum industry during the process of crude oil production in offshore field. Many non-intrusive sensor measurement technologies have been applied in sand production monitor, most of them measuring ultrasonic signals of more than 100KHz generated by sand particles impacts on the pipe wall. This paper illustrates a alternative vibration signature analysis method to measure the sand production. A special broadband vibration sensor was installed at the outside of pipeline to receive sand signals. Meanwhile, vibration signals generated by sandy crude were analyzed by time-frequency method. A simple test was used to ensure the approximate scope of characteristic sand frequency band. By applying these characteristic sand frequency bands, there is a distinguish between sand production well and no sand production well below the 20KHz. After that, both of the characteristic frequency band filter method and a peak searching-denoising method were used to maximize extract the sand signals in strong crude oil background noise. By using these methods, the normalized power spectrum was selected to reveal the difference between sand production well and no sand production well, and sand production characteristic can be observed in real-time. The measurement results of two different sand production wells showed that there is a good correlation between the normalized vibration power spectrum amplitude and the sand content. This result is also consistent with the supplied results by field tests. Therefore, this vibration signature analysis was effectively used to detect the sand production phenomena, and it would be helpful to apply low-cost vibration sensor technology to monitor the sand production in offshore field exploitation.
Novel Uncertainty-Based Well Test Design and G&G-Consistent Interpretation Technique Delivers Results in the Arctic for Wisting Field, Norwegian Barents Sea

Abstract
Well tests for smart, horizontal wells in faulted and heterogeneous reservoirs with complex fluids and uncertain contacts are nearly impossible to design and interpret with geological consistency using traditional analytical methods. Such cases lend themselves to numerical reservoir simulation, but the number of uncertain parameters and their interaction can make design difficult and the interpretation process time-consuming. We used an uncertainty-based technique for test design and interpretation with numerical models for a test in the Norwegian Barents Sea. We describe a new global sensitivity analysis methodology to determine how the interaction of multiple uncertain reservoir parameters (such as water contact depth, fault transmissibility, reservoir permeability, and anisotropy) influences the uncertainty in the pressure derivative response. With time-dependent plots of parameter sensitivity, confident decisions can be made about the test duration and the ability to address test objectives.
Our methodology shows how exploration of the full range of reservoir uncertainty gives confidence in the expected flowing conditions, which are used to manage operational risks. The results of the design study, which are fully-integrated with the geological and geophysical description of the reservoir, are used during real-time monitoring and final interpretation. The full methodology was applied for the first time to a well test targeting the shallow Mid-Jurassic Stø Formation in Wisting discovery, the northernmost oil discovery situated in the Hoop area of the Barents Sea. The test design clearly indicated that water breakthrough was not expected but that gas production could not be ruled out given the range of uncertainty of the reservoir parameters.
The test was monitored in real time. From the hundreds of cases produced and analyzed, matches were obtained during monitoring to give an indication of the future behavior of the well during the final buildup. This helped to dictate the test plan and buildup duration.
As predicted, interpretation of the final derivative was challenging due to reservoir complexity. Traditional analytical interpretation could easily have suggested sealing faults in the near-well vicinity. However, using an amalgamated numerical model derived from the initial real-time matches and then further calibrated to the test data, we provided an interpretation of all the data obtained during the test, including matching the liquid ratios and accounting for wellbore dynamics. We not only achieved a good pressure and pressure derivative match with a model coherent with the geology, but also confirmed connected volumes.
Reservoir Management of Skjold: A Mature, Waterflooded, Fractured Chalk Field in the North Sea
Authors: Orman Jack , Harrer Andreas 
Published: March 2017

Abstract
Skjold is a mature, water flooded fractured chalk oilfield in the Danish North Sea. A satellite to the Gorm complex, it has been on production since 1982 and has produced 300 million stb of an estimated 790 million stb initially in place (38% recovery factor to date). The field is operated by water injection due to insufficient aquifer support. One major current challenge is that many of its wells produce at &gt;95% water cut. The main reason is that a large proportion of the injected water is recycled through the same parts of the reservoir which are by now already well swept. These are often highly fractured areas of the field, connected via specific zones in the injection and production wells. The result is that large quantities of unproduced oil remain behind pipe at production wells.
A project called Skjold LTRO (Locate the Remaining Oil) was set up with the intention of identifying viable ways to increase the Skjold production and reserves. An initial data grounding exercise was undertaken where the rich Skjold static and dynamic dataset was thoroughly analysed. From this, significant insight was gained into how the Skjold reservoir is plumbed together. The natural progression was to integrate all the data and learnings, utilising the well-established platform of dynamic reservoir simulation. Concurrent data interpretation with permanent interaction across disciplines was key to arrive at a sound understanding of the complex fracture network which dominates Skjold reservoir fluid flow.
The work has led to the identification of multiple Skjold well intervention and water injection optimization opportunities: Throughout 2016, reduced water injection was trialled at specific Skjold wells. The trials have led to a sustained increase in field oil production potential of around 20%, as well as lowering operational expenditure (OPEX). A campaign of well interventions, based on the project learnings, has also been carried out in 2016. Finally, the project work has revealed that, several years prior to the end of field life, significant further value can potentially be added through completely shutting in the Skjold water injection, partly as a result of the pressure depletion leading to increased recovery from solution gas drive.
This paper describes how reservoir management is being approached for a late-life North Sea fractured chalk oilfield in a low oil price environment.

Abstract
Water management in the oil and gas industry has evolved rapidly to meet the needs in the various plays across the country through the boom, downturn, and now into the expected recovery. Operators and service companies have improved frac fluid chemistries to utilize non-freshwater sources, developed treatment technologies to reuse produced water, identified improved options to move and store water, and in many cases, developed internal teams of experts to work more closely with water stakeholders (EWI, 2015). While energy from oil and gas generally requires less water than other sources (Mielke, Anadon, & Narayanmurti, 2010; Scanlon, 2013), impacts to local water resources in already water-stressed regions can be significant. One area where this is true is the Delaware Basin of Southeastern New Mexico.
Devon's stacked pay potential in the Delaware Sands, Leonard Shale, Bone Spring, and Wolfcamp formations provides long-term development and growth opportunities. Economics have improved and operational risk has been reduced due to the innovative water recycling program which started with technology pilots in 2012 and expanded to become a core part of the Devon's Water Management Program for the area. Contrary to some public perception, the treatment of the water was not the only hurdle the team faced. Development of the program also required solutions to logistical problems related to storage and movement of the water and involved representatives from field operations, accounting, supply chain, completions, regulatory, and the water management team.
OS TELEFONES CELULARES E A APRENDIZAGEM COLABORATIVA NA SOCIEDADE DE SERVIÇOS: O DESDOBRAMENTO DA SOCIEDADE DA INFORMAÇÃO EM REDE
Authors: Medeiros Neto Benedito 
Published: March 2017

Este artigo trata de questões recentes da Sociedade da Informação em Rede no Brasil, quando dispositivos móveis, como o celular, chegam às mãos de pessoas, principalmente as com carência de recursos materiais e cognitivos, seja pela falta de capacitação e mediação ou acesso restrito às informações de utilidade pública. No estudo identificou-se que os novos dispositivos multifuncionais apontam para mudanças e transformações nas atividades pessoais, nas relações interpessoais e nas comunicações locais e globais. Por outro lado, percebe-se que segmentos econômicos, como Agricultura, Indústrias e Serviços, passam por mutações profundas, e em um futuro próximo, os Serviços se tornarão mais proeminentes e predominantes devido à economia digital. No estudo, comprova-se que a cognição junto com Cultura, em especial a Digital, associadas à Educação, levam os usuários à aprendizagem continuada, mas apenas quando a todos é facilitado a comunicação ubíqua e a computação pessoal dos celulares, ao mesmo tempo nos lares e ambientes de trabalho e/ou escolar. A sociedade caminha, não para um mundo de maravilhas com presença das TIC mediando as atividades do homem, mas ao contrário, para uma série de questões e disputas por bens e serviços, requerendo o poder moderador e regulamentador do Estado nas questões do trabalho, educação, saúde e segurança, pelo menos. Finalmente, mostra-se que o protagonismo, no Século XXI, permitido pela revolução informacional e das mídias comunicacionais, possibilita representatividade política, a reivindicação da falta dos serviços básicos para todos, e a possibilidade da melhoria da qualidade de vida, podendo levar ao fortalecimento de uma Sociedade de Serviços.

PÉRDIDA O PERMANENCIA: EL ACAPARAMIENTO DE LAS TIERRAS COLECTIVAS EN CHIAPAS DURANTE EL PORFIRIATO. UN ACERCAMIENTO A LA PROBLEMÁTICA DESDE LOS EXPEDIENTES DEL JUZGADO DE DISTRITO (1876-1910)
Authors: Fenner Justus 
Published: March 2017

La historiografía mexicana posrevolucionaria ha fomentado una leyenda que responsabiliza en alto grado a las compañías deslindadoras y colonizadoras (1875-1902) de apropiarse las tierras comunales, apoyadas por el aparato judicial federal y aprovechando las leyes sobre deslindes de terrenos baldíos del Porfiriato (1876-1910).
Según esta lectura, las compañías aprovecharon su posición de agentes de gobierno en agravio de los intereses territoriales de las comunidades y de los poseedores de terrenos no titulados, usurpando así extensas tierras para su venta a particulares, mientras los jueces rechazaban los juicios de oposición. Con la actuación de las compañías deslindadoras, el proceso de desamortización de las tierras comunales, iniciado con las primeras leyes agrarias del México independiente, llegó a su punto culminante.
Confrontada esta leyenda con la documentación histórica referida al estado mexicano de Chiapas, resulta una imagen, aún preliminar, que obliga matizar la tradicional visión de un mundo indígena desentendido del mundo ladino y expuesto a las arbitrariedades del mundo oficial y de los particulares. A la vez nos ofrece un nuevo punto de vista en la interpretación tanto de la actuación de la justicia federal como de las compañías deslindadoras en el proceso de privatización de las tierras comunales. Esta perspectiva nos permite revalorar la evolución de la pérdida de las tierras colectivas en su justa dimensión y bajo enfoques que complementan los tradicionales.

Published: March 2017

El objetivo de este artículo es identificar la composición de la persona rarámuri y describir cada uno de sus elementos. Más allá de reconocer la noción de cuerpo y de las entidades que lo animan, en el análisis se enfatizarán las relaciones que dan pie a nuevos componentes de tipo emocional, cognitivo y onírico. La salida del alma es un eje fundamental en el pensamiento rarámuri, a través de ella se explican los estados de salud-enfermedad y vida-muerte. El presente es un texto etnográfico que busca contribuir al conocimiento antropológico de las culturas del norte de México, particularmente del noroeste.

ABSTRACT
The proposal of this paper is to identify the composition of the raramuri person and, to describe each part of its components. Beyond recognizing the notion of the body and the entities that animate it, this investigation emphasizes those relations that allow new emotional, cognitive and oniric components to be formed. The outcoming of the soul is a fundamental axis in the Raramuri thought by which the status of the health-illness and life-death is explained. The following ethnographic text pretends to contribute to the anthropological knowledge about the cultures in northern, particularly north-western, Mexico.
EL CUERPO Y LA PERSONA EN EL ESPACIO-TIEMPO DE LOS MAYAS DE LOS CHENES, CAMPECHE
Authors: Hirose López Javier 
Published: March 2017

Para los médicos tradicionales mayas de la región de los Chenes, en el estado de Campeche, winik, el término que designa a la persona, hombre o individuo (Barrera Vázquez 2001), está estrechamente ligado al simbolismo de los rituales de sanación y los principios de la cosmovisión maya. En contraste con la visión cartesiana del mundo, propia de la mente occidental, que separa el cuerpo de la mente y el espíritu, para los mayas la persona se manifiesta en su forma material, el cuerpo, kukut, como reflejo del cosmos, con cuatro rumbos y un centro, y se conforma por los elementos de la naturaleza: tierra, agua, fuego, viento y luz. Simultáneamente, los mismos componentes que conforman su materialidad se manifiestan como entidades sutiles a través de las cuales el individuo se interrelaciona con los diferentes niveles del cosmos. Dicha interacción se da en un espacio delimitado por cuatro lados, cuyo movimiento —en contrasentido al giro de las manecillas del reloj— lo liga con el tiempo.

ABSTRACT
For the mayan traditional healers of the Chenes region in Campeche, winik, the term used to designate a “person”, “man” or “individual”(Barrera-Vázquez 2001), is closely linked to the healing rituals and the principles of mayan cosmology. The Cartesian world view, proper to the occidental mind, separates the body from the mind and the spirit. In contrast, for the mayan, the person has a material aspect, the body, kukut, which resembles the cosmos, with four orientations and a center, and is the manifestation of the elements present in nature: earth, water, fire, wind and light. Simultaneously, the same components that conform its materiality, are manifest as subtle entities that let the individual interact with the different levels of the cosmos. This interaction takes place in a dimension defined by a four sided space which moves in the universe in a counter-clockwise direction.

Published: March 2017

Este documento pretende mostrar una problemática macrosocial al considerar la construcción de derechos humanos religiosos y de los pueblos indígenas en los ámbitos internacional y nacional, y cómo son o no retomados por las instancias nacionales no solo para la solución de conflictos religiosos sino también para garantizar los derechos humanos religiosos de los pueblos indígenas. Desde esta perspectiva interesa también, a la luz de los conflictos religiosos, observar cómo son ejercidos los derechos políticos y sociales por los indígenas y si los operadores de la justicia los toman en cuenta.
ABSTRACT
This document aims to demonstrate a set of macrosocial problems regarding the construction of religious human rights and the human rights of indigenous peoples in the international and national spheres, and how they are or are not considered by national authorities, not only in resolving religious disputes, but also protecting the religious human rights of indigenous peoples. From this perspective, and in light of ongoing religious conflicts, the document also looks at how political and social rights are exercised by indigenous peoples, and whether said rights are taken into account by the administrators of justice.
