Autobio-graphiées : enjeux discursifs de la représentation du Moi dans la bande dessinée féminine franco-belge
Authors:   Universidad de Granada (España), Blanco Cordón Tatiana
Published: December 2021

The French autobiographical comic written by women constitutes a growing genre which reveals a huge diversity and richness of expression. Through a representative corpus of albums, we will endeavour to clarify to what extent these publications bring new narrative perspectives with respect to the standard comic form and how they contribute in a specific way to Self-representation. Our discussion is interested, above all, in the contention between sincerity and dissimulation in the construction of an autobiographical portrait. The study of the interdependent relationship in this double coded medium, between the text and the iconograph, allows us to delve into the pragmatics of the comic on which the discursive challenges posed by the female authors, are based
Le paysage thanatique et féminin chez Gustave Moreau. Étude mythocritique de Orphée sur la tombe d’Eurydice
Authors:   Universidad de Granada (España), Flores-Fernández María
Published: December 2021

This article proposes to define the thanatic landscape as the manifestation of Hermes-Mercurius archetype within the symbolic universe of Gustave Moreau, specifically on Orphée sur la tombe d’Eurydice (1891) and his preserved writings. This is defined according to the duality that is so present in Moreau’s pictorial and literary work; between the text and the image, the tangible and the spiritual, the sacred and the profane, the masculine and the feminine. How do the human and sepulchral landscape elements, of religious and mythological origin, merge in the imaginary of the decadent literary painter? In response, this study includes a myth criticism approach and aims to apply the archetypal theory to the symbolic hermeneutics of landscape
De adverbio de constituyente a adverbio de actitud enunciativa: sincèrement, franchement, entre nous
Authors:   Universidad de Sevilla (España), Mellado-Damas Adelaida Hermoso
Published: December 2021

"The aim of this article is to propose an analysis of the French adverbs sincèrement, franchement and entre nous as semantic-pragmatic operators. Within a polyphonic framework (Anscombre, Donaire y Haillet [éds]: 2013), we shall see in which way the use of each unit in discourse determines the organization of different points of view convoked by the utterance act. Our interest is to prove that both franchement and entre nous involve a previous point of view which they are against, while sincèrement denotes the speaker’s psychological attitude to the message content. In order to confirm this hypothesis, we propose some criteria, both distributional and semantic-pragmatic, that show the kind of discourse strategies theses expressions involve"
Les Lumières sous le prisme d’un mot : l’emploi du mot citoyen dans quelques ouvrages français du XVIIIe siècle
Authors:   Universidad Complutense de Madrid (España), Lastičová Adriana
Published: December 2021

"This study explores the use and the utilisation of the word citoyen in Eighteenth-century French literature before the revolution of 1789, of which the word is considered one of the symbols. We have gathered a corpus of works of reflection and fiction, published especially around 1750-1770, which we consider representative of the phenomenon and contrastive at the same time. Thanks to the methodological basis of the discourse analysis and the semantics that have a wide range of descriptive and methodological categories we are able to outline the practices associated with the word citoyen in the literary discourse in the course of the eighteenth century and we raise the question of the intertextuality between works of reflection and fiction."
Franceses y españoles en el Cádiz de 1700 a través de Voyages du P. Labat des FF. Prescheurs en Espagne et en Italie
Authors:   Universidad de Cádiz (España), Rubiales Bonilla Lourdes
Published: December 2021

"Our point of departure shall be the volume in which Jean-Baptiste Labat (1663-1738) devotes to his stay in Spain in Voyages du P. Labat des FF. Prescheurs en Espagne et en Italie (1730a). In this light, our paper shall explore some biographical, sociohistorical and literary clues in order to understand the author’s relationship with Spain as well as the representation of the relationships between Spanish and French communities in his account. With a focus on what unites rather than on what separates both communities, our purpose is to highlight the elements interfering with the apparently stable opposition between «We» and «They» in Labat’s discourse."

"...Kościół tak niezwykle zły, że zdaje się być oborą", czyli jak przekonać luteranów do wizyty w brzydkim kościele.
Authors: Gruk Wojciech
Published: December 2021

"...Kościół tak niezwykle zły, że zdaje się być oborą", czyli jak przekonać luteranów do wizyty w brzydkim kościele. Problem wyglądu i lokalizacji świątyni w kazaniu konsekracyjnym pielgrzymkowego kościoła granicznego w Cigacicach (1655, wyd. 1665).
Artykuł poświęcony jest problemowi niedogodnej lokalizacji kościoła i jego brzydoty jako czynników potencjalnie zniechęcających wiernych do jego odwiedzania, oraz próbom ich dyskursywnego przezwyciężenia. Podstawą źródłową artykułu jest opublikowane w 1665 r. kazanie pastora Zachariasa Textora na okazję poświęcenia granicznego kościoła pielgrzymkowego położonego w odludnym Lesie Cigacickim w Marchii Brandenburskiej. Wedle słów kaznodziei była to budowla tak skromna, że pielgrzymom – luteranom z sąsiedniego księstwa głogowskiego, gdzie ich kult był zakazany – przypominała ona raczej oborę niż kościół. Artykuł zawiera rekonstrukcję wykładu Textora mającego na celu pozytywną reinterpretację negatywnych cech świątyni, przeprowadzoną w oparciu o historię biblijnego Jakuba (Rdz 28). Analiza wywodu Textora pozwala lepiej zrozumieć znaczenie budowli kościelnej i jej wyposażenia w specyficznej kulturze pielgrzymkowej śląskich luteranów, kształtującej się po wojnie trzydziestoletniej, dając podstawy do pełniejszej interpretacji związanych z nią dzieł architektury i sztuki. Artykuł wzbogacają liczne cytaty z kazania, w tym obszerne fragmenty unikatowego opisu nieistniejącej od stuleci prowizorycznej świątyni.
Idea participatio actuosa Soboru Watykańskiego II w dobie pandemii
Authors: Filipowicz Krzysztof
Published: December 2021

Niniejszy artykuł jest próbą odpowiedzi, jak soborowa idea participatio actuosa mogła być realizowana w warunkach pandemii Covid-19.  Uczestnictwo w liturgii zakłada jedność czasu i miejsca. Możliwości oferowane przez współczesne media spełniają zasadniczo warunek uczestnictwa co do jedności czasu. Znacznie większy problem dotyczy jedności miejsca, co pociąga za sobą ograniczenia uczestnictwa w liturgii rozumianej jako świat osób i relacji. Niewątpliwie, nawet tak ograniczony sposób uczestniczenia nie musi automatycznie narzucać ograniczeń co do skuteczności w porządku łaski. Kwestie te były już podnoszone podczas obrad Soboru Trydenckiego. Oznacza to, że nawet ograniczenia narzucone przez pandemię nie wykluczają całkowicie z włączania się człowieka w opus Dei. Obok analizy dokumentów poświęconych liturgii, artykuł uwzględnia badania socjologiczne religijności Polaków w dobie pandemii.
Posługa muzyka kościelnego w świetle Musikalisch-liturgisches Wörterbuch Bernharda Kothego (1821–1897)
Authors: Pawlik Karolina
Published: December 2021

W tradycji Kościoła katolickiego muzyka stanowi nieodzowną i integralną część jego uroczystej liturgii. To stwierdzenie przypomina o trwającym od wieków przekonaniu o jedności tych dwóch rzeczywistości. Na przestrzeni wieków różne przyczyny powodowały okresy lepszej lub gorszej kondycji muzyki liturgicznej. Drugą połowię XVIII i początek XIX wieku przyjęło się uważać za czas kryzysu. Przejawiał się on przede wszystkim w niskim poziomie wykształcenia, niedbalstwie i swawoli muzyków kościelnych, a także braku odpowiedniej literatury muzycznej i czerpaniu ze świeckich wzorców. W odpowiedzi na te zjawiska w 1868 roku powstało towarzystwo Allgemeiner Cäcilienverein. Ruch ten zrzeszał duchownych i świeckich zaniepokojonych stanem ówczesnej muzyki kościelnej. Szczególny nacisk położono na edukację. W tym celu zaczęto opracowywać zbiory literatury muzycznej, podręczniki, czasopisma. Jedną z takich pozycji jest wydany w 1890 roku słownik Musikalisch-liturgisches Wörterbuch Bernharda Kothego. Jest to uporządkowany zbiór wiadomości ujętych w formie podstawowych haseł wraz z ich opisami, co nadaje mu formę leksykonu. Zawiera on nie tylko ogólną wiedzę muzyczno-liturgiczną, ale także przemyślenia autora na temat posługi muzyka kościelnego.

“The story is too wordy”: M. Gorky and the Failed Writer Mark Volgin (The Plot of the Novel “Emigrants” and the Fate of Its Author)
Authors:   Gorky Institute of World Literature of the Russian Academy of Sciences, Moscow, Kudrina Elena V.
Published: December 2021

The article is devoted to the plot of Mark Volgin’s novel “Emigrants”. Letters of the writer Olga Nikolaevna Nikiforova and her mother, Lyudmila Alekseevna Nikiforova, to M. Gorky were found in the Gorky Archive of the Institute of World Literature. They asked the writer to read the manuscript “Emigrants” signed with the pseudonym Mark Volgin and give a review. The manuscript was sent from Harbin in July-August 1935. Gorky read the novel and wrote an answer in October. Gorky’s letter about the novel reached the addressees only in early 1936. We learn about the content of the novel from the letters of L. A. and O. Nikiforov and the letter of the Deputy People's Commissar of Foreign Affairs B. S. Stomonyakov. Mark Volgin’s political novel depicted the whole essence of emigrant life. The novel interested the Harbin Consul M. M. Slavutsky and M. Gorky. Gorky advised Nikiforova to work on it seri-ously. The manuscript of the novel “Emigrants” has not been preserved in Gorky’s Archive. The fate of two more copies of the manuscript is unknown. New, previously unpublished let-ters of Gorky’s correspondents are being introduced into scientific circulation.

Una reflexión sobre el proceso de adaptación a la pandemia en la educación superior
Authors: Ortiz Leopoldo
Published: December 2021

La pandemia originó la mayor interrupción de los sistemas educativos de la historia de la humanidad. Afectó a casi 1600 millones de estudiantes en más de 200 países. Los cierres de escuelas, instituciones y otros espacios de aprendizaje han afectado a más del 94 % de la población estudiantil mundial. Esto ha traído cambios profundos en todos los aspectos de nuestras vidas. Las políticas de distanciamiento social y movimiento restrictivo han perturbado significativamente las prácticas educativas tradicionales. La necesidad actual es innovar e implementar sistemas educativos alternativos y estrategias de evaluación. La pandemia nos ha dado la oportunidad de allanar el camino para introducir el aprendizaje digital. Se revisan los cambios en la pedagogía digital que se han dado en respuesta a la pandemia. Se aborda el desafío que significa lograr el equivalente a un proceso de aprendizaje de diez años en unos pocos meses. Desde la mirada hacia la pedagogía en la educación superior como una arena de experimentación del desarrollo humano, se evalúan las características de una disciplina habilitada digitalmente y su alineación con las teorías del desarrollo humano. Considera que las oportunidades generadas por la transformación digital y los procesos de desarrollo humano son adecuadas para facilitar nuevos enfoques en la práctica académica de la educación superior.
La nostalgia prístina y la vulnerabilidad de las trabajadoras domésticas en Roma, de Alfonso Cuarón
Authors: Camps Martín
Published: December 2021

Alfonso Cuarón calificó a Roma (2018) como “su primera película”. Filmada en blanco y negro, narra la historia de Cleo, una trabajadora doméstica en una casa de la colonia Roma, donde trabaja para una familia de clase media que está pasando por el divorcio de los padres. Cleo se embaraza de un hombre que la desprecia. La familia tambiénes testigo de la represión del gobierno en el llamado “Halconazo” de 1971. Me interesa la película no solo por la belleza estética en la cuidadosa reconstrucción de una memoria, sino también por exhibir la jerarquía de clases y las estructuras de dominación hacia las empleadas indígenas que huyen de la pobreza y el atraso rural como resultado de un Estado desinteresado en las comunidades minoritarias.
El devenir del deseo. Análisis de En busca de Aladino, El goce de la piel y Capricho en azul, de Oswaldo Reynoso
Authors: Paredes Morales Judith
Published: December 2021

En este artículo se pretende analizar el devenir del deseo en los textos En busca de Aladino (1993), El goce de la piel (2005) y Capricho en azul (2020), de Oswaldo Reynoso. El lenguaje del escritor peruano interpela el repudio para buscar un deseo que le es adverso y que, sin embargo, resulta gozoso. Nuestro objetivo es investigar el devenir, según Deleuze y Guattari, de la escritura de la memoria, de otra sexualidad, donde las fronteras del tiempo y el espacio se resemantizan a partir de la liberación de la matriz heterosexual. De ese modo, la escritura de Reynoso cuestiona la perfomatividad del género, categoría estudiada por Butler, al ubicarse en el límite de la inteligibilidad e imaginar el deseo homoerótico. A fin de revelar una secuencialidad diferente a la heterosexual.
Entrevista a Juan Villoro. Apuntes para un elogio del ornitorrinco
Authors: Rabí do Carmo Alonso
Published: December 2021

Juan Villoro, escritor y periodista mexicano nacido en 1956, es actualmente uno de los principales cronistas latinoamericanos de nuestra época. Autor de novelas, cuentos y notables ensayos, su pasión por la crónica lo ha llevado a elaborar una teoría sobre este popular género en América Latina. Se trata, nada menos, de considerar la crónica como un “ornitorrinco”, analogía apropiada para un discurso que reúne elementos de distinta procedencia y los mezcla funcionalmente, como un ornitorrinco, que reúne cualidades de diversos animales: es mamífero, ovíparo, vive buena parte de su vida en el agua, tiene pico de pato y cola de castor. En esta entrevista, Juan Villoro recuerda sus antecedentes familiares, el modo en que construyó su vocación de escritor y, naturalmente, practica agudas reflexiones sobre la crónica.
Las ciudades, el cambio climático y la energía incorporada
Authors: Chumpitaz Requena Favio
Published: December 2021

El desarrollo de nuestras urbes es el causante del más del 70 % del dióxido de carbono (CO2) que se produce y posee un gran impacto sobre el medio ambiente. Las consecuencias de estas formas de “desarrollo” ya están presentes y se incrementarán en las siguientes décadas. La reducción del impacto depende de diversos factores, entre ellos, de la energía incorporada como una posibilidad en la arquitectura y el urbanismo, a fin de ser utilizada como una herramienta general para toda infraestructura. Bajo este criterio, la energía incorporada puede constituirse en un nuevo punto de partida que formule cuestionamientos respecto de los planteamientos arquitectónicos y urbanísticos tradicionales, a partir de nuevas prioridades materiales y sociales.

The article includes proprietary data and data from literature from the last 30 years about the fluctuations in concentration and the elemental and biochemical make-up of the dissolved and particulate organic matter (DOM and POM, respectively) in the different ecosystems of the Barents Sea. The large variability of these values in both surface and deep waters is shown, depending on the intensity of the hydrological and biological processes.DOM concentrations varied from 59 to 664 μMCorg, while POM varied from 0.25 to 38.08 μMCorg. The reduction of the ice cover affected both the distribution and the qualitative composition of the DOM and the POM. This reduction, as well as the increased flow of Atlantic waters, contributed not only to an increase in the primary production of organic matter, but also to a significant intensification of redox and hydrolytic processes of its transformation, especially in the high-latitude part of the Barents Sea. The DOM of the sea is characterized by high C / P ratios, far exceeding those of Redfeld. At the same time, C / N ratios in the most productive waters are close to those of Redfeld. We highlighted four regions in the sea where concentrations of dissolved carbohydrates increase towards the bottom, which indicates that oil hydrocarbons are supplied here.

The results of the study of the distribution and composition of the dispersed sedimentary matter (suspended matter) in the water column of the Barents Sea were presented in the article. The distribution of suspended matter in the sea obeys the laws of circumcontinental (for surface distribution) and vertical zonality. At the same time, the absolute values of the weight and volume concentrations of the suspended matter themselves are low (on average less than 0.5 mg/l and less than 1.0 mm3/l, respectively). The highest values of all parameters of the suspended matter were found in the Pechora Sea, the most southeastern part of the Barents Sea, where the abrasion of the shores and bottom erosion, and the Pechora River runoff. Surface and bottom peaks are characteristic of the vertical distribution of the suspended matter. An intrusion of the nepheloid layer enriched in the suspended matter into the deep layers can be observed on the continental slope when the depth makes a sharp fall.

Published: December 2021

Hot questions in the modern Quaternary geology of the Arctic seas associated with their glaciation are discussed in this article. The questions of the history of the occurrence of the problem of shelf glaciation or “drift” accumulation of boulder-bearing sediments are considered in detail. The results of seismic-acoustic studies and their interpretation with the aim of seismic stratigraphic and genetic partition of the cover of loose sediments of Quaternary age are considered in detail. Arguments are presented in favor of the continental origin of glaciers (Novaya Zemlya, Ostrovnoy and Scandinavian), which in the late Neopleistocene spread to the shelf of the Barents Sea and occupied its surface to depths of 120−150 m. Further development of glaciation was already due to the expansion of the area of shelves glaciers. The facies zoning of glacial-marine deposits is estimated, which is related to the distance from the front of the glaciers. It is concluded that already at the end of the Late Pleistocene, most of the modern Barents Sea was free from glaciers and from the annual cover of pack ice. Data on the absence of the area distribution of frozen sediment strata within the modern Barents Sea shelf are presented.
Ostracods in the sediments of the Arctic shelf seas of Eurasia (stratigraphy and paleoreconstruction)
Authors:   Texas A&M University, College Station, USA, Stepanova A.Yu. , Taldenkova E.E. ,   Lomonosov Moscow State University
Published: December 2021

We present data on ostracod assemblage analysis from the Laptev, Kara and White Seas in the Arctic Ocean. We established the relationship between modern ostracod distribution and environmental parameters and applied this knowledge to interpret fossil Quaternary ostracod assemblages. Data on distribution and ecological parameters for different modern Arctic and Boreal species give us an opportunity to interpret even taxonomically poor samples. Late Pleistocene-Holocene ostracod assemblages from the eastern Arctic shelves and their stratigraphic succession in the studied cores reflect the environmental transition during the gradual deepening of the sites and distance increase from the coastline during the Postglacial sea-level rise. Variations in fossil ostracod assemblages at the continental slope location suggest temporal increases in modified Atlantic water inflow, as well as point to periods of glacier meltwater and freshwater input. Late Saalian-Eemian assemblages from the White Sea area contain typical Arctic representatives as well as taxa inhabiting boreal and more southern locations and the majority of species present are known to tolerate decreased salinities. Assemblage changes reflect the transition from the initial stage of inundation, with active hydrodynamics, to stable marine conditions with subsequent warming and shallowing of the basin.

The field has been producing since 1974 under active aquifer drive followed by peripheral water injection which resulting in a high recovery factor of oil production. Cumulative oil production is more than 900 MMbbls and currently the field is still producing at 15000 bopd. The Handil Main zone is the main contributor that accounts for 60% of the Handil Field production and based on the results of new wells drilling, there is still potential of the remaining oil accumulations. Therefore, an integrated subsurface study is needed to further increase recovery in the Handil Main zone. This paper will discuss the process used to locate unswept oil in the high water cut reservoir to extend the water flood project. Waterflooding became an important part of the Handil’s development strategy to maximize oil recovery and to maintain oil reservoir pressure, as more and more fields are matured as part of their production life cycle. The main challenge is to identify area of unsweep oil that are affected by water injection activity. Understanding the reservoir behavior of the water injection sweep characteristic can significantly improve the understanding of the distribution of unswept oil in the reservoir. A robust integrated methodology was developed to identify unswept oil area by integrating Static- dynamic synthesis, 3D static model, production history, reservoir connectivity, recent well logs data and reservoir simulation. Multiple QC of oil sweet spot are done by comparing the sweet spot area of dynamic synthesis with reservoir simulation. Detailed well correlation were performed to identify the optimum water injector placement to improve the recovery factor. The results of the integrated dynamic synthesis are used to identify the sweet spot area and the optimum well injector location that will be used for the water flooding development project to be executed in 2022. The results of the study will sustain Mahakam production in the future.
The Shaped PDC Cutter and Special Bit Element Utilization to Improve Overall Drilling Performance in Hard Massive Carbonate: A Case Study of ERD Horizontal Well In Offshore East Java, Indonesia
Authors: Fajar I.
Published: December 2021

Drilling through hard massive carbonate formation combined with naturally induced torsional vibration due to bit-formation interaction is often resulting in unnecessary down time caused by downhole tool failures, sub-optimal drilling performance and extra trip to change out worn out bit. The torsional vibration is also well known as as stick and slip. To address the challenge, special PDC bit with advanced cutter technology were utilized in ERD well in Offshore East Java. The key focus when selecting the bit was on PDC cutter shape selection to improve drilling efficiency and utilization of higher strength material elements to improve stability and impact durability of the cutting structure critical in drilling hard and harsh rocks. The bit record, bit type configuration, QA/QC process, hydraulic & stability analysis and secondary cutter materials consideration were also specifically analysed when selecting this bit to improve bit performance further and ensure the bit could be repairable & reusable after being used. The first field run of the bit incorporating all this technology mentioned above was performed on last two (2) ERD well drilled in East Java Offshore area, at the 8.5in hole section with 7 bladed, 16mm cutter. The bit successfully drilled total of 3,029 ft interval through massive carbonate formation for both wells. The bit reached target depth without bit change. The bit had proven to reduce drilling torsional vibration stick & slip from severe to medium level. Both bit run also had set considerably remarkable slip-to-slip Rate of Penetration (ROP) for ERD wells category, which had significantly improved by 69.35% compared to previous ERD well drilled in same carbonate formation with ERD profile. When on surface, the bit was observed still in excellent condition for this application. The enhanced PDC bit selection had proven to enable drilling into more challenging torsional vibration induced formation in massive Carbonate formation and challenging ERD trajectory thus improving overall drilling performance and achieve actual rig time & cost saving compared to plan.

Authors: Khoironi B.
Published: December 2021

Buntal is a mature gas field located in South Natuna Sea Block B PSC. The field was discovered by well Buntal-1 and delineated by appraisal well Buntal-2. The field consists of multi-stacked sandstone reservoirs, which were deposited under fluvial deltaic environment. The major Buntal reservoirs have been produced since 2004 from two subsea wells. Buntal-3 was producing from zones Beta-1 and Beta-2, while Buntal-4 was a horizontal well producing from Zone-1C. Both of those wells had loaded up prior to Buntal-5 drilling. This paper describes the details of a multidisciplinary approach taken for the proposal of Buntal-5 infill drilling. An integrated geological and geophysical study were carried out to quantify resources and uncertainties of the remaining thin unproduced zones. In total, there are 8 virgin zones as Buntal-5 initial target namely Beta-0, Zone-1A, Zone-1B, Zone-1D, Zone-1E, Zone-2B, Zone-3 and Zone-3A. Max-trough seismic amplitude was utilized to identify geological features across for each Buntal reservoir. The result was then combined with geological concept based on its depositional environment to justify a reasonably higher hydrocarbon volume which can not be estimated only by wells’ data. A reservoir simulation study was also carried out to not only to evaluate production potential from the virgin zones but also to capture upside potential from the produced zones. Simulation history matching result on Zone-1C revealed early water breakthrough experienced by Buntal-4 well due to water cresting phenomena which left significant gas reserves. This result added upside potential to Buntal-5 which initially only targeted marginal remaining unproduced zones. The well was drilled at the end of 2019 and proven to be a major success. Buntal-5 open hole logs data indicate thicker and better virgin zones reservoir quality as expected by integrated geological and geophysical study. Furthermore, significant remaining gas was encountered in Zone-1C with actual gas water contact was within the simulation result proving the water cresting theory, the zone itself add well’s gas-in-place by 30% on top of the unproduced zones’ gas-in-place.
Continuous Circulation while Drilling: A New Approach to Maintain Hole Cleaning and Improve Drilling Performance in Swamp Drilling Operation
Authors: Yuda B. K.
Published: December 2021

Swamp drilling operation in Mahakam has entered the industrialization period in which fast drilling is a common practice. However, fast drilling Rate of Penetration (ROP) causes hole cleaning issues to arise and induce a high Equivalent Circulating Density (ECD) trend. In some wells, this potentially leads to loss problems because of weak formation in shallow sections or depleted formation with relatively low fracture gradient. As a result, drilling parameter reduction was performed that causing lower ROP and additional circulation to reduce ECD. A new technology called Continuous Circulation Device (CCD) can help to tackle the problems mentioned above. It is a sub-based constant circulation system that enables the continuous circulation of drilling fluids downhole while making or breaking drill pipe connections. This system helps to maintain ECD and improve drilling performance as the cuttings are continuously carried out of the hole. This paper is introduced to analyze the benefits of CCD and opportunities for future development in the swamp drilling operation. The device was applied during drilling in the 12-1/4” and 8-1/2” sections. The challenge during drilling in these sections was to improve ROP without inducing bad hole cleaning that could lead to a high ECD trend. The result of CCD utilization shows that ECD during drilling could be reduced up to 2 points and become more stable compared to the previous trend. Since there was a reduction of ECD, the ROP could be improved up to 10%. Furthermore, only 1 cycle for circulation at well TD was performed as the minimum cuttings appeared. Pulling out the string and running the casing string was managed smoothly as the hole was already in a good condition. This utilization has been successfully implemented without any safety incident nor related Non-Productive Time (NPT). This positive result leads us to open the opportunity for future development in swamp fields asset.

Authors: Zakyan H.
Published: December 2021

Enhanced Oil Recovery (EOR) come up with promising result to endure mature fields production performance and has been proven worldwide in many various methods. Recently, Low Salinity Water Injection evolves as a simply operation and relatively low cost EOR method with wide of research and implementation seem to be proved effective in the past decades. Some laboratory tests have indicated that injecting low salinity water can improve conventional waterflood performance by 5 – 20%. Hence, it introduces a promising idea that Low Salinity Water Injection should be implemented to mature fields in Indonesia for EOR activity. This paper will focus on determining the optimum salt concentration of injection water for low salinity water injection. Low salinity water injection in this study will be acted as a secondary recovery method. The production performance as a result of low salinity water injection was acquired by numerical simulation using tNavigatorTM Simulator. This simulation will be conducted in Tangai Structure at Sukananti Field, South Sumatera Basin, Indonesia with Talang Akar Formation reservoir target. The simulation is conduct with the constraint injection rate of 1,340 BWIPD. The low salinity water is designed by dilution of salt concentration from formation water with 18,000 ppm of concentration. In this case, the sensitivity of low salinity water, mainly amount of salt concentration design, will be conducted in the simulation consisting of using formation water as scenario’s base case and various low salinity water designs which will be limited until 10x of dilution (1,800 ppm). The result of this study concluded that Low Salinity Water Injection achieved more oil recovery than conventional waterflood did. This incremental is caused by wettability alteration due to of salt concentration changes which attract the clay minerals in reservoir through many complex mechanisms. The simulation result shows that injection water with 10x dilution (1,800 ppm) is chosen as an optimum salt concentration design, which gives the best result with gains additional oil recovery and recovery factor about of 118,8 MSTB and 4,9% respectively from a scenario by injecting formation water (18,000 ppm).
Application of Unbalanced Load Sharing to Compensate Low Compressor Train Capacity
Authors: Putra Y. H.
Published: December 2021

Oil and gas fields often operate two or more compressor trains in parallel instead of one big compressor train to optimize reliability and capital investment. These compressor trains are usually designed to be loaded equally in order to avoid excessive design margin, to operate at highest efficiency point, and to prevent any compressor from operating too close to its surge region (McMillan, 1983). However, this configuration means the lowest train’s capacity dictates overall system’s capacity. This paper shares Banyu Urip Central Processing Facility (BU CPF)’s successful strategy to compensate capacity decrease in one of its gas injection train using unbalanced load distribution. Upon implementation of the strategy, BU CPF managed to maintain operations at 100% gas injection capacity even though the capacity of one of the train was limited to 70%, therefore eliminating unplanned downtime or production curtailment.

Successful Sand Consolidation Portfolio Expansion Through Comprehensive Parameter Control
Authors: Abidiy I.
Published: December 2021

In accordance with the cost-saving campaign in Mahakam block, sand consolidation was successfully developed as a cheaper alternative to sand control. Despite the limited development of sand consolidation market and the successful application of sand consolidation products from the current incumbent, Company faces the risk of limited access to other products and potential failure to switch existing products. However, self-validation for any desired product with lower risk exposure is considerable. Taking all the necessary lessons learned during initial product development, the successful application of sand consolidation depends on proper control of product deployment rather than the product composition itself. The systematic arrangement of all controlled parameters generates a causal relationship, which will act as a validating workflow to the other 3 new products. During the deployment of these products in 17 wells, all parameters were successfully controlled and it was possible to make the wells producing with a success rate of more than 90%. Based on this study result, Company will have more flexibility in using sand consolidation products variation by considering the associated resources: attractive pricing, contractual fairness, and logistic access.
