Research on energy indexes of cogenerated plants with gas turbines and heat recuperator steam generators
Authors: Sarria-López Bienvenido
Published: January 2020

The main objective of this paper is the experimental investigation of the energy indexes of a cogeneration plant with Gas Turbines (GT) and Heat Recuperator Steam Generators (HRSGs) while changing its operational load. The energy indicators were determined using the following International Standards and Codes: ASME PTC1, ASME PTC 22 and ASME PTC 4.4. The results of energy calculations indexes are in the form of curves. The mathematical equations of the curves corresponding to the real energy indexes are obtained applying multivariate regression.The main research results correspond to a process plant with nominal capacity of 4800 kW. The range of lower energy consumption values obtained for the HR of the turbine are around 13000 kJ/kW·h, while for the Heat Rate of the plant is 7000 kJ/kW·h. For these values of the Heat Rate (HR), the electrical output remains in the environment of 3500 kW. It was found that the thermal efficiency of HRSGs varies from 50 to 60% with very high values of sensible heat losses in flue gases due to the operation with high excess air and high temperatures of the gases at the outlet of HRSGs. The contributions of this research are used in operational management in order to reduce fuel consumption and environmental impact on the generation of electricity and heat cogeneration plant evaluated. The results of this research in the plant have been implemented to monitor the transaction on the basis of the variation in real-time energy indexes evaluated, besides the traditional control of the parameters only, which is more effective.
Methodology to increase oil reserves by identifying optimal time to abandon non-economic wells
Authors: Sandoval Publio-Alejandro , Fernández Fabián-Ricardo , Ordoñez-Rodríguez Aníbal , Rincón-Bonilla Claudia , Jerez Leydy-Johana
Published: January 2020

Estimating reserves is one of the most important tasks in the oil industry. It is the process that determines the recoverable oil in a field, area or region. However, incorporating the production of a well beyond its economic limit has the effect of loss of value, because it forces economically good wells to sustain those that are not. A corporate vision of the topic, calls for greater attention to strategies to select wells for abandonment, as an important variable in the planning of production scenarios and estimating reserves. The purpose of this paper is to describe the methodology used to obtain higher value in reserves calculated for a given asset, by analyzing direct production costs and the design of an optimum well abandonment timetable.

The methodology can be applied in all the fields in which an analysis of this type has not been considered, which run the risk of having incorporated in their reserve estimate a number of wells in which the economic balance is negative, thus affecting the performance of the reservoir's better wells.

Additionally, it includes a case application of the methodology involving a field in a Colombian basin. The results show a 5 year extension in economic limit, with a significant increase in the amount of the asset's recoverable reserves.
Artificial lift management: Recommendations and suggestions of best practices
Authors: Hirschfeldt Clemente-Marcelo
Published: January 2020

Artificial lift systems (ALS) play an important role during the oil field production process. The selection, acquisition, installation, evaluation, monitoring and subsequent inspection of these systems involves different stakeholders, including the companies and different sectors therein. When you add factors such as field location, local culture and the experience of the companies in the area, understanding and analyzing each of the factors is critical not only to maximize the life of a specific ALS, but also to maximize and optimize field production in an efficient, effective manner. Another important factor to consider is the dynamic of developing new oil fields or those affected by different EOR technologies, such as secondary recovery by water injection, where field requirements and conditions change on a continuous basis.

This paper presents concepts and recommendations regarding the management of ALS during the productive life of an oil field, contemplating the criteria of selection, acquisition, installation, evaluation and monitoring, as well as the subsequent inspection thereof. The issues analyzed herein also involve concepts related to operating as well as service companies and sectors involved in acquisition, evaluation and monitoring, among others. It also mentions definitions of the roles, functions and competencies required to live up to the challenges posed by these systems.
Fluid migration history from analysis of filling fractures in a carbonate formation (lower cretaceous, middle Magdalena valley basin, Colombia)
Authors: Conde-Gómez Jairo , Mantilla-Figueroa Luis-Carlos , Naranjo-Vesga Julián-Francisco , Sánchez-Rueda Nelson
Published: January 2020

The integration of Conventional Petrography, SEM, Rare Earth Element geochemistry (REE) and Fluid Inclusions analysis (FI), in the fracture fillings at the Rosablanca Formation (Middle Magdalena Valley basin), make it possible to relate opening and filling events in the veins with hydrocarbon migration processes.Petrographic and SEM data indicate that the veins are fracture filling structures, with three types of textures:1) Granular aggregates of calcite (GA); 2) Elongated granular aggregates of calcite (EGA); and 3) Fibrous aggregates of calcite and dolomite (FA). The textural relationship suggests that GA must have been formed in an environment of widespread extension of the basin, while EGA and FA must have been formed in a compressive environment.

The geochemical analyses of REE carried out in the dominant fill of the veins (GA) indicate that these fillings must have been formed in a closed system (intraformational fluid movement) for the drilling well Alfa-1, while in the drilling wells Alfa-2 and Alfa 3, these fills (GA) must have been formed in a characteristic environment of open system (transformational fluid movement). Two pulses of hydrocarbon migration were identified through the study of fluid inclusions: In the first event, light hydrocarbons and aqueous fluids (H2O-NaCl-CaCl2) migrated trough the primary porosity and fractures at temperatures between 60ºC- 90ºC. In the second event, light hydrocarbons associated with aqueous fluids (H2O-NaCl-CaCl2) migrated through fractures at temperatures between 70ºC - 120ºC. Data obtained in this investigation will strengthen the knowledge about the hydrocarbon migration history and entrapment in the Middle Magdalena Valley basin (VMM) particularly in the lower Cretaceous age reservoirs.
Dense suspensions formulations for upgrading processes in heavy and extra heavy crude oil
Authors: Rodríguez Lilia , Viviescas Geoffrey
Published: January 2020

The present work involved the formulation of solid-liquid suspensions of by-products of heavy and extra heavy crude oil process upgrades, coke and asphaltenes from Delayed coking and Deasphalting processes. This was done by controlling rheological properties and following specifications for pipeline transmission, similar to those of liquid hydrocarbons. The formulated products guarantee the possibility of moving the by products in a fluidized way, minimizing storage, handling, environmental and operational costs in transportation, and providing an attractive alternative as non conventional fuel.

Regarding the formulation of suspensions, it was necessary to establish the effect of formation components such as: surfactants, stabilizers, as well as the type, amount of solids and particle size ratio on the flow properties of the resulting product. The parameters analyzed for rheological properties of pipeline transport were viscosity, particle size distribution, static and dynamic stability.

Laboratory tests were performed in high precision rheometers -TA Instruments RX1500 and Haake RS600- and Mastersizer 2000 particle size analyzer. At pilot scale, we used a closed loop to verify flow parameters, including normal and critical transport scenarios: Sudden shutdowns and extended ones of up to 72 hours, with subsequent pumping re-starts.

Tests performed at the lab and the pilot plant showed better rheological properties in the formulations with bimodal particle size distribution. This allowed higher loads of solid, up to 52%, and an improved mobility, reflected as lower viscosity. A non-Newtonian rheological behavior became evident, characterized by yield stress to ensure pumpability after prolonged inactivity. The pressure drops and calculation of apparent viscosity obtained in the pilot plant were compared and verified with lab results, showing reproducibility.

EFEKTIVITAS PENAMBAHAN SUPLEMEN HERBAL PADA PELLET TERHADAP PERTUMBUHAN DAN KELULUSHIDUPAN IKAN PATIN (Pangasius hypophthalmus)
Authors: Kurniawan Ronal , Syawal Henni , Effendi Irwan
Published: January 2020

Penggunaan tumbuhan sebagai alternatif suplemen pakan memiliki kelebihan, salah satunya bersifat bio-degradable dan ramah lingkungan, serta mudah ditemukan di alam, seperti kunyit, temulawak, dan kencur. Tumbuhan ini bersifat antibakteri dan antimikroba, serta meningkatkan laju pertumbuhan dan sistem imun ikan. Tujuan penelitian adalah untuk mengetahui efektivitas dari penambahan suplemen herbal pada pakan buatan dalam meningkatkan laju pertumbuhan dan kelulushidupan ikan patin. Penelitian ini dilaksanakan pada bulan Juni s/d Agustus 2019, di Waduk Fakultas Perikanan dan Kelautan Universitas Riau, Pekanbaru. Metode yang digunakan adalah metode eksperimen dengan menerapkan rancangan acak lengkap (RAL) dengan empat perlakuan, yaitu P0 (kontrol), P1 (dosis suplemen 100 mL/kg pakan), P2 (200 mL/kg), P3 (300 mL/kg). Ikan dipelihara dengan padat tebar 75 ekor/m3, panjang 7 cm dan bobot 6 g, serta dipelihara selama 60 hari. Hasil penelitian menunjukkan bahwa pemberian pakan buatan dengan penambahan suplemen herbal mampu meningkatkan pertumbuhan dan tingkat kelulushidupan ikan patin. Dosis pemberian suplemen herbal sebesar 200 mL/kg pakan menghasilkan laju pertumbuhan dan tingkat kelulushidupan ikan patin terbaik, menghasilkan pertumbuhan bobot mutlak sebesar 119,08 g, laju pertumbuhan spesifik 4,86%/hari, panjang mutlak 15,45 cm, konversi pakan 1,21, efisiensi pakan 82,93% dan tingkat kelulushidupan 100%. Kualitas air selama penelitian berada dalam kisaran yang mendukung untuk pertumbuhan ikan patin, yaitu suhu berkisar antara 26,9-30,2oC, oksigen terlarut berkisar antara 4,3-6,1 mg/L, dan pH berkisar antara 6,1-6.8.
Pour une genèse littéraire de « l’esthétique de l’existence » : Pasolini, Barthes, Foucault
Authors: Luglio Davide
Published: January 2020

L’hypothèse que nous voudrions formuler est celle d’une analogie entre la capacité propre à l’expression artistique de se soustraire à l’emprise du pouvoir et le concept d’“esthétique de l’existence” tel que l’élabore au début des années quatre-vingt Michel Foucault. Le fondement de cette analogie réside dans ce que nous appellerions une textualisation de la vie : la vie est vue comme un langage et sur cette base elle peut être pensée – “écrite” et “lue” – comme un texte. Cette extension du domaine du langage à la vie occupe une place importante dans les derniers travaux de Roland Barthes mais elle avait été postulée avant lui par Pier Paolo Pasolini. Pasolini est le premier à considérer que la vie peut, voire doit, être considérée dans une perspective qui est à la fois politique et esthétique. Dans Poeta delle ceneri, Pasolini affirme qu’on peut « écrire de la poésie avec la vie ». Le poète italien ouvre ainsi la voie à une réflexion éthique et politique sur la vie comme œuvre d’art, et sur l’œuvre comme exemple de résistance à l’emprise du pouvoir et comme modèle dans le processus de subjectivation.
Des bords et débordements : la pensée à la limite de Jacques Rancière
Authors: Ferrer Rey Lorena
Published: January 2020

Dans l’un de ses ouvrages les plus récents, Les Bords de la fiction, Jacques Rancière reprend la question des limites et des débordements, qu’il avait examinée auparavant dans Aux bords du politique, un livre dont la première édition est parue en 1990. À ce moment-là, le philosophe s’intéressait surtout à la topographie métaphorique construite dans la pensée politique, c’est-à-dire à l’usage des métaphores spatiales, parmi lesquelles l’on trouve celle du bord. Presque trente ans plus tard, la réflexion s’est déplacée, par contre, au domaine de la fiction littéraire. Mon but dans cet article est de rapprocher ces deux moments de l’œuvre de Rancière afin d’y trouver un arrière-plan commun à partir duquel continuer à penser le nouage du littéraire et du politique. Pour ce faire, je propose d’analyser quelques œuvres littéraires écrites au fil des années 1990 (le moment clé autour duquel s’articule Aux bords du politique) dont les titres font référence à l’enjeu des bords o des débordements : le Journal du dehors et La vie extérieure d’Annie Ernaux, ainsi que le roman Vivir afuera, de l’écrivain argentin Rodolfo Fogwill. Quel imaginaire topographique mettent-elles en place ? Et quelle est la signification politique des métaphores spatiales dont elles se servent ?
Corpos pós-humanos e com deficiência em ambientes digitais
Authors: Pessoa Sônia Caldas , Mantovani Camila Maciel C. Alves , Costa Verônica Soares da
Published: January 2020

A partir da campanha #somostodosparalímpicos, da revista Vogue Brasil, discutimos dinâmicas sociopolíticas do corpo e representações do corpo com deficiência no senso comum e nas redes sociais digitais. A metodologia partiu de uma abordagem de inspiração etnográfica para análise qualitativa, com o objetivo de compreender as relações sociopolíticas da representação de corpos e a representação de pessoas com deficiência a partir de mensagens articuladas pela hashtag da campanha. Foram analisadas as articulações entre a visibilidade da deficiência e o relacionamento simbiótico entre homem e máquina nas mídias sociais no contexto dos Jogos Paralímpicos. Se, por um lado, a campanha garantiu o aumento da venda de ingressos para a Paralimpíada, por outro, minimizou a representatividade de pessoas com deficiência tendo em vista a substituição dos paratletas por atores e a hibridização com corpos supostamente belos.
Memória visual e representação do rock e da jovem guarda nas capas de discos LP (1959-1970)
Authors: Vargas Herom , Bruck Mozahir
Published: January 2020

O rock brasileiro nos anos 1960 foi uma música de grande sucesso e importância para a indústria fonográfica. Dentre várias mídias, as capas de discos se destacam por representarem a música, a juventude e as articulações da memória na fotografia e no design. O objetivo deste artigo é entender a construção da memória do início do rock no Brasil e da jovem guarda por meio das representações visuais nas capas dos long-playings (LPs). O corpus compreende as discografias de 35 artistas, entre 1959 e 1970. Usamos as noções de representação (HALL, 2016; LOTMAN, 1998); memória (HALBWACHS, 1990; HUYSSEN, 2001; POLLAK, 1989; BOSI, 2003; RICOUER, 2007); performance (ZUMTHOR, 2010) e design (DONDIS, 2003). O estudo destaca as representações de corpos e comportamentos, e como o design traduziu rock e juventude nas capas.
