A Necropolitical Approach to Waste Theory
Authors:   Universidade da Coruña (España), Fernández Fernández Martín
Published: March 2023

Achille Mbembe’s Necropolitics (2019) provides an innovative approach to dissect human relations in a contemporary world where an increasing number of people are deemed superfluous and disposable under late capitalist logic. His book offers a genealogy of the current state of affairs from a post-Foucauldian perspective that centers on the notion of race and the conception of sovereignty in Western liberal democracies. Rarely associated with Waste Theory, Mbembe articulates a necropolitical approach that complements Zygmunt Bauman’s conception of “human waste” and Giorgio Agamben’s theorizations on the figure of the homo sacer. This article thus argues that Mbembe’s Necropolitics stands as a major contribution to the field of Waste Studies, in that it encloses a reflection on the racial Other as human waste from a perspective that has not been sufficiently studied

Authors: Jena Pragnya , Duggal Shalini , Gur Renu , Kumar Avinash , Bharara Tanisha , Dewan Rekha
Published: March 2023

Objective:

Breast abscess is a significant cause of morbidity especially in young women of childbearing age. These abscesses are associated with physical, psychological disturbance, and long-term cosmetic consequences.

Materials and Methods:

This was a prospective study that involved seventy cases of breast abscesses to identify etiological agents and their susceptibility patterns.

Results:

Lactation was a risk factor in almost two-third of all cases. Others were diabetes mellitus, extremes of age, immunocompromised conditions, and tuberculosis. The most common bacterial isolate was Staphylococcus aureus (83.3%), almost half being methicillin-resistant S. aureus (MRSA). Others included coagulase-negative Staphylococcus, Enterococcus spp., Streptococcus spp., Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Candida spp., and acid-fast bacilli.

Conclusions:

The treatment of all such microorganisms is different, signifying that microbial diagnosis plays a pivotal role in management of such abscesses.
Unusual cause of seizures: Imported fire ant bite reaction
Authors: Abinaya O. , Moorthy Swathy
Published: March 2023

Imported fire ant (IFA) species can lead to a lot of allergic manifestations. This can vary from pustular eruptions at the bite site to anaphylactic shock, cardiac, and neurological manifestations. We are presenting an unusual manifestation of ant bite – a 56-year-old woman who developed seizures following a bite of IFA. She experienced an ant bite on her back following which she developed seizures. She had a similar episode 5 years back following ant bite (similar in appearance). This being an unusual presentation, was treated as a primary seizure disorder. She had discontinued therapy due to allergic reaction to the anti-epileptic drug. On presentation to our hospital, she was screened for organic causes for seizures that were negative. Her description of the ant matched with that of IFA – Solenopsis invicta and was confirmed by physical verification. The patient was advised about avoidance of ant bites, using fully covered clothing at the workplace.

Published: March 2023

Isolated area postrema syndrome (APS) is a rare neurological presentation of, neuromyelitis optica spectrums disorder (NMOSD), recognizable by uncontrollable hiccups, nausea, or vomiting. When it occurs as the first presentation of NMOSD, it may present as a diagnostic challenge as the condition may be frequently attributed to gastrointestinal pathology, and the subsequent diagnostic delay may result in debilitating neurological sequelae such as optic neuritis or myelitis. We report such a case of isolated APS in a young woman who presented with a clinical picture of bouts of vomiting and intractable hiccups causing considerable distress and was finally diagnosed to be a case of seronegative NMOSD.

Relevance. The main modifiable risk factor for the development and progression of glaucoma is intraocular pressure (IOP). For over two hundred years, there has been a search for a method for determining the level of IOP, which took into account the properties of the surface of the cornea and iatrogenic factors. Purpose. To assess the influence of individual characteristics of the eyeball on the difference in ophthalmotonometry, measured by the Maklakov's applanation method and using point contact tonometry (iCare). Material and methods. The work involved 226 patients aged 45 to 89 years (342 eyes) with a diagnosis of primary openangle glaucoma (POAG) (71 eyes) or suspected glaucoma (202 eyes). The study also used data on the observation of healthy eyes (69 eyes). The study is analytical, observational, case-control. The leading diagnoses at the time of the study were: primary open-angle glaucoma (POAG) and suspected glaucoma. Also, data on observation of healthy eyes were used in the work. Clinical refraction varied of ±6.0 diopters and astigmatism ±3.0 diopters. All patients underwent ophthalmic tonometry measurement using the Maklakov applanation method (with a load of 5, 10 and 15 g) and iCare point contact tonometry (Tiolat, Finland). Results. The results of point contact tonometry were relatively underestimated relative to the tonometric indicators by Maklakov's tonometry: 5 g – 4.1±4.0 (4.0 [1.0; 7.0]), 10 g – 9.7±4.0 (10.0 [6.5; 12.5]), 15 g – 14.7±4.2 (15.0 [12.0; 18.0]). Conclusion. The reasons for the difference from the Maklakov's tonometer require further study; they can be associated both with the measurement method, the patient's body position, the characteristics of the group set, and various approaches to the calibration of the tested tonometers. A positive point is the higher numbers of ophthalmotonus in Maklakov's tonometry, since this is the main screening method of ophthalmotonometry on the territory of the Russian Federation.

Disaster-resilient villages: strengthening community capacity in flood disasters managing in wetland areas
Authors: Arisanty Deasy , Hastuti Karunia Puji , Putro Herry Porda Nugroho
Published: March 2023

Wetland areas have the potential for flooding during the rainy season. Even though the community is used to a flooded environment, disaster risk reduction must be carried out immediately when the inundation exceeds the standard limit and causes losses including establishing a disaster-resilient village. This study aims to analyze the role of disaster-resilient villages in strengthening communities in the face of flood disasters in wetland areas. This study used a questionnaire with 100 respondents from two flood-prone villages, Sungai Lumbah Village and Bangkit Baru Village. In addition, in-depth interviews were conducted with community leaders in the two villages, the Sungai Lumbah Village Head, Bangkit Baru Village Head, volunteer groups and the Head of the Barito Kuala District Disaster Management Agency. The results showed that the two villages were still included in the Primary Disaster Resilient Village category. The two villages were still not ready when the disaster struck. The institutional aspect is still not prepared, the funding aspect is still low and the planning aspect is inferior. The communities of the two villages were still not ready when the disaster occurred. Various efforts were made to increase socialization from both the Government and academia to increase the number of volunteers and to increase training to create a disaster-resilient society.

Published: March 2023

Fifteen complexes of Hg(II) of the type [HgX2.L1-5] with macrocyclic ligands derived from 9,10-phenanthren-quinone and different aliphatic diamines NH2(CH2)nNH2 (where n = 2 or 3 or 4 or 5 or 6) have been synthesised and characterised by elemental analysis, molar conductance, Hirshfeld analysis, IR and XPS data. An octahedral geometry was established with diamagnetic nature for each molecular adducts. Hirshfeld surface analysis was utilised to characterise the 3D intermolecular interactions on the crystal surface while fingerprint plots were used to illustrate the 2D interactions. Increasing H-H/C-H/O-H/C-C linkages helped to stabilise 9,10-phenanthrene-quinone.
Vibrational studies of 2,3,5,6-tetrachloro-1,4-benzoquinone and its reactivity: An ab-initio computational method
Authors: Kushwaha A. , Dwivedi Smriti , Prasad R.L.
Published: March 2023

The IR spectrum of 2,3,5,6-Tetrachloro-1,4-benzoquinone (p-chloranil) has been recorded in the solid phase in the range 4000 – 400 cm-1. ab initio calculations have been performed using Gaussian 03 program to compute optimized geometry, harmonic vibrational frequencies along with intensities in IR and Raman spectra and atomic charges at RHF/6–31+G*, B3LYP/6-31+G*, B3LYP/6-31++G** and B3LYP/6-311++G** levels for p-chloranil and parent molecule p-benzoquinone. The optimized molecular structures are found to be planar and possess D2h point group symmetry for both the molecules. The C=C bond lengths are larger whereas the C=O bond lengths are shorter in p-chloranil as compared to p-benzoquinone which is also reflected in the corresponding vibrational frequencies. The atomic arrangements in p-benzoquinone and p-chloranil possess two concentric hexagonal arrays and both the arrays of p-benzoquinone contain mixed charges. In the case of the p-chloranil molecule, the outer array is negatively charged and the inner array is positively charged which leads to increased susceptibility at the sites to which chlorine atoms are attached in p-chloranil towards the nucleophile. Consequently, p-chloranil is a good candidate for synthesis of many derivatives of 1,4-benzoquinone. The optimized geometrical structures along with the atomic charges on the atomic sites of p-benzoquinone and p-chloranil reveal the reactivity of p-chloranil molecules towards nucleophilic substitution reactions as compared to p-benzoquinone.
The poor’s opportunities of participation in economy digitalization
Authors: Pavlov A. V.
Published: March 2023

The subject of this study is to identify social problems among the poor in the process of digitalization of the economy and to develop proposals for their elimination. The scientific novelty lies in the presentation of the position that in order to involve the poor population in the digitalization of the economy, who need state social assistance, it is not enough to provide its traditional types – due to the lack of legally prescribed duties and (or) economic incentives necessary to perform certain actions. One of these types of state social assistance to the poor is its socio-economic stimulation – combining both state social assistance and economic incentives. An approximate sequence of measures for the socio-economic simulation of the poor population regarding its involvement in the processes of digitalization is presented. The methodological basis of the research consists of general scientific methods – analogies, analysis, synthesis, formal-logical, as well as special methods – comparative and descriptive analysis, and other methods. The relevance of the topic is due to the lack of norms in legislation regulating public relations regarding the participation of the poor in digitalization.

Authors: Pukhareva T. S. , Shutova Ya. A.
Published: March 2023

The article presents the results of a theoretical and empirical study of the meaningfulness of life and responsibility of medical workers. The diagnostic procedures used «the test of life-meaning orientations» and «Multidimensional functional diagnostics of responsibility (OTV–110) » [2, 10]. As a result of the study it was revealed that respondents are distinguished by a high level of meaningfulness of life, perceive their own life as productive, focused on achieving goals and effectiveness. It is shown that medical workers have a holistic understanding of the essence and various aspects of responsibility, are serious about performing of difficult and important tasks, react internally to possible failures in their professional activities, are sensitive to the difficulties and problems of other people. Connections of life-meaning orientations and parameters of respondents’ responsibility are established. In conclusion, it is stated that the results of the study may be useful in predicting the improvement of the professional efficiency of medical workers and planning opportunities for their further professional growth.

Published: March 2023

BACKGROUND: Diseases caused by arboviruses are currently a worldwide public health problem. These diseases have the Aedes aegypti mosquito as the main transmission vector, and the main strategy to combat their spread is the interruption of the mosquito life cycle in its early stages. In this study, we synthesized thirteen thiazolidinedione derivatives (3a-3m) that were applied in a larvicide-based strategy against the Ae. aegypti vector and submitted to evaluation of toxicological effects. RESULTS: Microwave process intensification was utilized for the synthesis of thiazolidinedione derivatives (3a-3m). One thiazolidinedione derivative stands out (3a) with lethal concentrations (LC50-24 h) of 7.71 μg mL-1 (32.16 μmol L-1). It showed embryotoxicity to zebrafish at concentrations up to 1.0 μg mL-1 and mortality from 3.1 up to 100 μg mL-1. No biochemical disturbances occurred based on GST and LDH measurements. A para-substituted chlorine atom instead of hydrogen improves toxicity profile. CONCLUSION: The substitution pattern with a chlorine atom suggests a larvicidal activity. From the compounds tested, (Z)-5-(4-chlorobenzylidene)thiazolidine-2,4-dione (3a) was the most effective against Ae. Aegypti, showing embryotoxicity to zebrafish.

Published: March 2023

Secondary alcohols bearing both axial and central chirality comprise attractive biological activity, and also exhibit excellent chiral induction in asymmetric reactions. However, only very limited asymmetric catalytic approaches were developed for their catalytic synthesis. We herein describe visible light-mediated cobalt-catalyzed asymmetric reductive Grignard-type addition of axially prochiral biaryl dialdehydes with aryl iodides, leading to the direct construction of axially chiral secondary alcohols bearing aldehyde groups. Preliminary mechanistic studies indicate efficient kinetic recognition of diastereomers might occur to improve the diastereoselectivity, which might open a new avenue for the challenging cascade construction of multiple chiral elements. This protocol features excellent enantio- and diastereoselectivity, green and mild conditions, simple operation, and broad substrate scope, providing a modular platform for the synthesis of secondary axially chiral alcohols.

Published: March 2023

The aim of the article is to study the implementation of European standards in the field of transportation of solid household waste (SHW). The relevance of the study is associated with the lack of coverage in the professional literature of the issues of solid household waste management in Ukraine, the transition to European standards in this area. During the study, methods of comparison, analysis and synthesis were used to determine the features of solid household waste management in Ukraine and the EU countries. The recommendation approach was used in the process of drafting proposals for the transition to European standards for solid household waste management. The analysis of the current state of SHW management in Ukraine has identified the following trends: growth in the volume of SHW; the composition of SHW is becoming more diverse; positive attitude of the population towards greening the collection of SHW. The main problems in the system of municipal enterprises engaged in the transportation of solid household waste and in the system of public administration in the field of waste management were identified. When comparing European and national legislation in the field of SHW transportation, the legal framework and basic principles of waste management were described. Comparing the experience of waste management in Ukraine and abroad allowed to identify the gap in the scale and pace of creating a SHW management infrastructure. The article proposes measures to improve the national SHW management system: determining the stages of development of SHW management systems; intensification of the transition to the organization of the separate waste collection and the process of implementation in Ukraine of European legislation in this area.

INCIDENTS OF THE FORMATION OF ENVIRONMENTAL HISTORY AND ECOLOGICAL ANTHROPOLOGY IN RUSSIA. ON THE DISSIMILAR FATE OF FOREIGN TERMS
Authors:   Udmurt Institute of History, Language and Literature of the Ural Branch of the Russian Academy of Sciences, Puzanov Daniil V.
Published: March 2023

The article provides a comparative analysis of the processes of adapting of the disciplines formed in the USA (“ecological anthropology”, “environmental history”) to national ethnography and history, respectively. In the early 1980s V.I. Kozlov was the first to attempt institutionalizing a special science that is on the border of the subject fields of ecology and ethnography. As a result of his active actions, the name “ethnic ecology” was fixed for a vast field studying questions related to ecology and ethnography. The literal translation of “ecological anthropology” and “ethnoecology” (in the meaning in which the term is used in the West) in Russia is usually used only when describing a foreign tradition. During the formation of the national ecological history, there was a direct transfer of the foreign tradition to the Russian soil, supported by the activity of foreign institutions. Therefore, the issue of constructing the name for a new discipline in Russia is more connected with the question of translating “environmental history”. The analysis of two opposite ways of institutionalization of new scientific directions allows us to take a fresh look at the issues of national specifics of the general subject structure of social and humanitarian knowledge and the role of the subjective factor in the formation of scientific traditions.
TITULAR HERALDRY OF THE MOSCOW TSARDOM AND THE WESTERN EUROPEAN HERALDIC TRADITION
Authors:   Russian State University for the Humanities, Pchelov Evgenii V.
Published: March 2023

The article analyzes the history of the influence of the European heraldic tradition on the titular heraldry of the Moscow Tsardom of the 16th – 17th centuries. There are two stages of such influence with its own characteristic features for each. The first stage was associated with the formation of the first complex of titular coats of arms, which were presented on the Great Seal of Ivan IV, made in the late 1570s. Among the 24 titular coats of arms of the Great Seal, five coats of arms were borrowed from the heraldry of the Baltic States and the Grand Duchy of Lithuania. They meant those territories that were annexed during the Livonian War or claimed by Ivan IV. Seals and even coins of that time acted as sources of heraldic images. From them images were transferred to the Great Seal without any changes. In other words, it was a direct borrowing of European coats of arms into the heraldry of Russia. The second stage is connected with the creation in 1672 of the tsar’s “Titulyarnik” (Titular Book), the first Russian compilation of coats of arms. Of the 33 coats of arms of the “Titulyarnik”, nine were directly borrowed from European heraldry (mainly from the heraldry of the Polish-Lithuanian Commonwealth). However, the methods of borrowing were more diverse. In addition to the direct transfer of the armorial figures, the coats of arms were changed, Christian symbols was strengthened in them. On the other hand, coats of arms could be borrowed on the principle of belonging to a certain category of territories. Finally, another way was to borrow either individual armorial figures or heraldic compositions. Such a variety of ways of borrowing clearly testifies to the increased heraldic culture of the Muscovy by the end of the 17th century.

Authors: TURFAN Nezahat , TURAN Buse
Published: March 2023

Since exogenous amino acid applications to agricultural plants provide ready mineral nutrition for plants, they are widely used to enhance the yield and quality of crops as well as to strengthen resistance to environmental impacts. In the present study, the effects of L-Glutamic acid (GLU) (100, 200, 400, 800, and 1000 mg L-1) treatments on the growth parameters, bulb yield, chemical contents, and weight loss of Taşköprü garlic were analyzed. Given the findings, 800 GLU dose was found to have the highest values in shoot length and width, fresh weight, width, and length of the bulb, length and of large and small cloves, and yield per plot. On the other hand, the lowest results in total free amino acid, nitrate, polyphenol, ascorbic acid, and % ash amounts were obtained with 400 GLU, while the maximum leaf length and width was obtained with 1000 GLU dose. The first and third weight losses were obtained in 100 GLU and control groups and the second weight loss value obtained in all groups were higher than in the control. Considering all the data, the doses of 800 GLU and 400 GLU yielded the most positive effect on growth parameters, bulb yield, and weight loss measurements in garlic, whereas the lowest level of effect was observed in the control and 100 GLU groups. In conclusion, it can be stated that the foliar application of L-Glutamic acid in garlic cultivation might increase the yield and quality.

Published: March 2023

Wheat stripe rust caused by the Puccinia striiformis f. sp. tritici (Pst) is a major and devastating biotic stress inducing notable product losses in wheat (Triticum spp.). Possibility of the breakdown of important genes conferring resistance against to stripe rust and the threat of emergence of new aggressive races remain a concern in all wheat growing areas around the world. Therefore, breeding programs must continue screening of wide genetic diversity to improve new varieties with different gene combinations against race changes. Within this scope, 140 wheat genotypes obtained from various countries and programs were evaluated in terms of their reactions to stripe rust at both seedling and adult-plant stages in 2020 and 2021 growing seasons. The adult-plant stage evaluations of these genotypes were conducted under artificial inoculation of PstS7 (Warrior) race at Haymana location of Field Crops Central Research Institute in Ankara and under naturally occurring local stripe rust population at Menemen location of Aegean Agricultural Research Institute in Izmir. Whereas the seedling stage tests were carried out using the PstS7 race under controlled conditions at Pest and Disease Resistance Unit of the Field Crops Central Research Institute. More than 80% of the genotypes tested at both locations exhibited immune, resistant, and moderately resistant reactions at the adult-plant stage, while only 36.4% of the genotypes exhibited resistance reactions at the seedling stage. The coefficients of infection (CI) of the genotypes were calculated by using the stripe rust reaction and disease severity of each genotype. Following scales were used for classification of the genotypes based on the CI: 0 = Immune; 0.1-5.0 = Resistant; 5.01-20.0 = Moderately Resistant; 20.1-40.0 = Moderately Susceptible; 40.1-100 = Susceptible. In conclusion, 101 genotypes (72.1%) evaluated at both locations were found to be immune, resistant, and moderately resistant to both the PstS7 race and local stripe rust population. These genotypes have been proposed as resistance gene sources for cultivars to be developed.

This paper discusses several technology initiatives and cost-effectiveness to optimize the drilling project in the Jambaran-Tiung Biru (JTB) Field. The design of the well shall meet the composition of 34% CO2 and 1% H2S in the reservoir. According to this sour gas condition and to meet the raw gas production of 315 MMSCFD, the project requires a specific design of the long-lead item. These had longer time delivery compared to the usual carbon steel. The Operator and SKK Migas took several initiatives for optimization. The drilling project was divided into two methods: drilling with a rig and completion with a rigless. The rig operation was optimized by applying a batch drilling sequence to meet material delivery time. Optimization also came from the drilling time on each hole section, mud utilization, casing, and cementing programs compared with the actual activities. Took corrective actions and learned about drilling problems. The completion job consists of perforation work 800 feet long in the reservoir target, well cleanup work, and production testing safe and effective. The well costs evaluated were based on the authorization for expenditure (AFE) compared with the actual cost estimate. The cost components that were evaluated include cost-per-foot and cost-per-day. The drilling project was completed 56 days earlier than planned. A Non-Productive Time (NPT) in an average of 3% and the results of the well test show that the production forecast is still as per plan. The estimated actual cost is 15% lower than the plan.
A Comprehensive Ensemble Modelling Study to Evaluate Subsurface Uncertainties Associated With Tangguh CO2 Enhanced Gas Recovery (EGR) Project to Deliver a Robust and Quality-Optimized Development Plan

Published: March 2023

Tangguh Field, in Bintuni Bay, Papua Barat Province, Indonesia, commenced development following a successful exploration program in the 1990s. Tangguh has been on production since 2009 through development of two liquified natural gas (LNG) trains (Kasim, Titus, Roberts, & Bulling, 2000). Full development includes a third LNG train with the expected first gas in 2023 and Enhanced Gas Recovery (EGR) and Carbon Capture Utilization and Storage (CCUS) in 2026. EGR/CCUS fits within the Government of Indonesia’s (GoI) gas production and carbon emissions reduction targets by 2030. The EGR/CCUS project will inject approximately 90% of reservoir CO2 back into the reservoir in the southwest part of Vorwata Field. Reservoir CO2, that is currently vented, will be captured from the Acid Gas Removal Unit, compressed, flowed via a subsea pipeline to an offshore facility, and then to injection wells. The CO2 is injected at supercritical conditions, to increase gas production and recoverable reserves through pressure maintenance and gas displacement mechanisms. Understanding the subsurface uncertainties and their impacts on production and operations are essential for optimizing field development plans and mitigating risks. The key risks to CO2 injection/capture are early CO2 breakthrough and reduced hydrocarbon recovery. bp’s proprietary Top-Down Reservoir Model (TDRMTM) based ensemble modeling workflow successfully assesses subsurface uncertainties, matches historical performance, and quantifies the value associated with the EGR/CCUS development. TDRMTM driven assisted history matching algorithm was matched the model against 12 years of historical production. Match qualities associated with historical rates and pressures were used as screening criteria to obtain a robust ensemble of history-matched models and ensure a healthy and sufficient exploration of uncertainties. The resulting metrics include the range of net hydrocarbon incremental gas recoverable, CO2 breakthrough times at offset producers, and CO2 sequestration volumes. Results from the ensemble-driven study have enabled a robust development plan, particularly associated with the
Fit-For-Purpose Waterflood Optimization in a Deflated, Mature, Tight Reservoir
Authors: Arnold R.
Published: March 2023

TK reservoir is a tight and heterogeneous sandstone formation. After a massive fracturing campaign and fast production build-up in the early production, the exploitation led to a severe pressure decline. Water injection project was then implemented in 2009, since which this pressure maintenance has been the life blood of this reservoir. However, after fifteen years of production and eight years of continuous water injection, there were still areas with low reservoir pressure leading to suboptimal production and low recovery factor. To improve the pressure maintenance which ultimately will result in improved oil recovery in this reservoir, a waterflood optimization project was initiated. The main fit-for-purpose strategy applied was to increase water injection rate through a convert-to-injector (CTI) campaign. The optimization was designed based on the estimation of incremental water injection rate required to increase the reservoir pressure. This step was then followed by strategic selection of wells that would be converted to injectors. After the best candidates were selected, the project were then executed and closely monitored. Significant improvement in waterflood surveillance and monitoring was also done to ensure the optimum waterflood performance. As the results of the on-going project, the reservoir pressure has been increasing and decline rate arrested. Significant reserve addition of 2.48 MMSTB had been enabled by this initiative through various activities, like infill drilling, hydraulic fracturing, artificial lift conversion, and shut-in well reactivation that would not be possible if the optimization was not realized beforehand. The present work addresses the reservoir and operational aspects of the journey of TK waterflood optimization. The workflow, analyses, and lessons shared in this paper are highly applicable to a low oil price environment, as they show how fit-for-purpose methodology and technology can lead to improved field performance.
An Effective Method to Improve Borehole Tortuosity and Tripping Out Speed in Interbedded Lithology Using Dual Cutting Eccentric Reamer in Swamp Drilling Operation
Authors: Yuda B.K
Published: March 2023

Handil field in Mahakam block has crowded wells and scattered reservoirs in which typical 3D trajectory such as S-type trajectory need to be done to respect anti-collision with surrounding wells and optimize reservoir coverage in a single line trajectory. However, a typical S-type trajectory causes a high stick-slip issue to arise and induces bad hole quality. In some wells, this potentially leads to additional time for dedicated wiper trips, a longer time during pull-out Bottom Hole Assembly (BHA), more usage of lubricant mud additives, and ROP reduction. As a result, a longer rig time would have occurred leading to a tight margin for a well to be produced economically. A technology called Dual Cutting Eccentric Reamer (DCER) could help to tackle the problem mentioned. It is a typical stabilizer BHA which has eccentric dual cutting structures that allows the tools to enlarge the hole then it passes through in two directions both when up-reaming and down-reaming. As a result, the tool helps improve hole quality as the tool also helps trim the ledges produced when drilling the hole. This paper is introduced to analyze the benefits of the reamer and its opportunity for future development in swamp drilling operations. The tool was applied during drilling on an 8-1/2” section. One of the challenges during drilling this S-Type trajectory was to minimize the difficulty during pull-out BHA that may lead to additional pull-out duration as well as the rig time or even dedicated wiper trip. The result of reamer utilization shows that pull-out BHA speed could be improved to 196 m/hr from 82 m/hr or 139% improvement compared with typical offset well. Furthermore, combined with good proper bit design and BHA configuration, the stick-slip issue could be minimized while ROP could be increased up to 9% compared to conventional well with S-type trajectory on the first trial. This utilization has been successfully implemented without any safety incidents and related Non-Productive Time (NPT). This positive result leads us to open the opportunity for future drilling campaigns in swamp asset such as DCER as the standard BHA configuration especially for S-type trajectory.
Low-Cost Flexible Riser Replacement on FPSO in a Marginal Field
Authors: Boondao, I.
Published: March 2023

This paper discusses a case study and challenges on a low-cost flexible riser replacement on FPSO in one of the offshore fields in the Gulf of Thailand. Once the flexible riser has gone past design life, a regular annular service test, inspection and risk assessment are required justify life extension. Considering the field lifetime and the risk associated with the riser, it is recommended that short term extensions are possible and warrants the replacement of the existing riser. Various alternatives and fit for purpose were reviewed to replace the original Coflexip API RP17J flexible riser with a low-cost material at estimate of 80% saving of the cost.
Integrated Facies Modeling in Shelf Margin Carbonate Field
Authors: Aip M.
Published: March 2023

A 125 km2 gas bearing, shelf margin carbonate is planned for development and production in the offshore field. The main static modeling challenge is to estimate the gas in place volume. This challenge is attributed to the wide and elongated structure of the field and is further amplified by the limited available well data. Moreover, based on nearby field analogue, the carbonate reservoir is expected to have high lateral and vertical heterogeneity. Hence, robust facies modeling is critical to determine depositional facies distribution and ultimately the calculation of the gas in place volume. The integration of various data is used to model the facies in gas-bearing carbonate reservoirs. In this facies modeling study, three wells log data and one core data are used in combination with seismic data. Additionally, shelf margin carbonate field conceptual geology is interpreted and visualized. The reservoir characteristic of the field from north to south can be interpreted as back reef, reef flat and reef front. Since the wave energy in the southern part is high and generally contains large fossil reefs, it creates better reservoir properties, such as porosity. The east to west reservoir distribution is simulated with better properties on the eastern area compared to the western area, as secondary porosity occurs on the eastern part, where it is interpreted as higher basement morphology and carbonate build up on the bottom of the reservoir. Two methodologies of facies modeling are introduced for distributing rock type in the field. As a guide for secondary variable facies modeling, two probability trend maps (trend map A & trend map B) are created based on the sketch of each rock type of shelf margin conceptual geology supported by seismic acoustic impedance trend maps extracted from 3D seismic cubes. The result of the two facies modeling is integrated in a static model as multiple realization volumetric to minimize uncertainty. As a result, the facies model has captured the possible scenarios to reduce subsurface uncertainty. The combination of the conceptual geology of trend map A and trend map B is an advantageous application for modeling an optimum facies model in shelf margin carbonate reservoir environment. Consequently, this methodology is enabling a more robust volumetric estimation in a high uncertainty.
