Brucellosis is a zoonotic disease endemic in developing countries and caused by gram-negative bacteria of genus Brucella infecting both livestock and humans. Brucella melitensis and Brucella abortus are important species representing largest biotypes world-wide. Therefore, modified detection strategies and advancement in potential analytical tools are required to monitor its rapid prevalence. In this study, we aim to modify gold-transducer of Surface Plasmon Resonance biosensor with combination of metal oxide nanomaterials and chemical probe to detect recombinant outer membrane ‘rOmp28’ protein antigen of Brucella melitensis 16M in concentration-dependent surface interactions. We synthesized Zinc (ZnONPs) and Gold (AuNPs) nanoparticles using standard ‘Hydrothermal and Turkevich Methods’ and their crystalline structure, chemical property and morphology were analysed using UV-Visible Spectrophotometry, FT-IR, Powder-XRD, SEM-EDX and TEM-SAED. For immobilizing specific rOmp28 derived IgG-pAbs on modified Au-transducer, rOmp28 protein was expressed and purified using Ni-NTA gel affinity chromatography for producing pAbs in BALB/c mice. Three modifications of Au-transducer with 4-MBA, ZnONPs/AuNPs and ZnONPs/AuNPs/4-MBA were subjected for immobilization and SPR biosensing was performed with rOmp28 Ag at detection range of 0.1 μg mL-1 to 0.01 fg mL-1. Limit of detection observed with ZnONPs/AuNPs/4-MBA combination was 0.1 fg mL-1 by relative increase in SPR response angle at 0.1 μg mL-1 in the order 83.7° < 98.9° < 179.2° for 4-MBA < ZnONPs/AuNPs < ZnONPs/AuNPs/4-MBA respectively. In conclusion, metal oxide nanomaterials in combination with biosensor are suitable in sensitive and specific interaction of antigen displaying lowest LODs and enhanced biosensor response for on-field real-time Brucella detection in both clinical and non-clinical disease scenario.

Metal-based nanoparticles are a promising class of materials for diagnosis and treatment of cancer and other diseases. However, mechanisms of action of these nanomedicines remain insufficiently understood due in large part to our limited understanding of the dynamic equilibria between solid metal nanoparticles and labile metal ions generated from these nanoparticles within complex biological milieus. Here we apply activity-based sensing to directly identify and investigate the fate of labile copper pools with metal and oxidation state-specificity generated by anticancer copper nanomedicines. We found that treatment of cells with copper-releasing CuFe2O4 and Cu2Fe(CN)6 nanoparticles alter labile Cu(I)/Cu(II) ratios through an increase in labile Cu(II), while overall labile copper levels decrease. Labile copper release triggers compensatory responses in two major antioxidant pathways, glutathione (GSH) and nuclear factor erythroid 2–related factor 2 (NRF2), as well as in metal homeostasis to limit copper availability via synergistic upregulation of copper export (ATP7B) and downregulation of copper import (CTR1) proteins. These findings establish the value of activity-based sensing as a generalizable approach for labile metal imaging to help decipher molecular mechanisms of bioactive metal nanoparticles and guide the development of more effective nanomedicine diagnostics and therapies to target metal-dependent disease vulnerabilities.
The fundamental relation between electrohelicity and molecular optical activity
Authors: Garner Marc H. , Corminboeuf Clemence
Published: March 2023

Electrohelicity arises in molecules such as allene and spiropentadiene when their symmetry is reduced and helical frontier molecular orbitals (MOs) appear. Such molecules are optically active and electrohelicity has been suggested as a possible design principle for increasing the chiroptical response. Here we examine the fundamental link between electrohelicity and optical activity by studying the origin of the electric and magnetic transition dipole moments of the π −π∗ transitions. We show that the helical character of the MOs drives the optical activity in allene, and we use this knowledge to design allenic molecules with increased chiroptical response. We further examine longer carbyne-like molecules. While the MO helicity also contributes to the optical activity in non-planar butatriene, the simplest cumulene, we show there is no relation between the chiroptical response and the helical π-MOs of tolane, a simple polyyne. Finally, we demonstrate that the optical activity of spiropentadiene is inherently linked to mixing of its two π-systems rather than the helical shape of its occupied π-MOs. We thus find that the fundamental connection between electrohelicity and optical activity is very molecule dependent. Although electrohelicity is not the underlying principle, we show that the chiroptical response can be enhanced through insight into the helical nature of electronic transitions.
Diffusion trapped oxygen in oxide derived Copper electrocatalyst in CO2 reduction
Authors: Lian Zan , Dattila Federico , López Núria
Published: March 2023

Oxide-derived Cu (OD-Cu) catalysts have shown an excellent ability to ensure C-C coupling in the electrochemical carbon dioxide reduction reaction (eCO2RR). However, these materials extensively rearrange under reaction conditions, thus the nature of the active site remains controversial. Here, we studied the reduction process of OD-Cu via large-scale molecular dynamics at first-principles accuracy introducing experimental conditions. The oxygen concentration in the most stable OD-Cu materials increases with the increase of the pH/potential/specific surface area. In long electrochemical experiments, the catalyst would be fully reduced to Cu, but it takes a considerable amount of time to remove all the trapped oxygen, and the highly reconstructed Cu surface provides various sites to adsorb oxygen under relatively stronger reduction potentials (U = –0.58 VSHE at pH=14, 0.25 VRHE). This work provides insight into the evolution of OD-Cu catalysts and residual oxygen during the reaction conditions and a deep understanding of the nature of active sites.

Microstructure of new boron-rich chalcogenides, orthorhombic B6X (X = S, Se) synthesized at high pressures and high temperatures, has been studied by high-resolution transmission electron microscopy. Two twins systems have been found along planes (101) and (002). Apart from numerous twins on the (101) plane, two types of polytypes were found: ABAB in both chalcogenides and AB1CD1AB1CD1 in B6Se. It has been shown that shear bands in B6S and cracks in both materials lie in planes {011}.
Uncovering the Regulators of CRISPR-Cas Immunity
Authors: Boncheva Idia
Published: March 2023

The clustered regularly interspaced short palindromic repeats (CRISPR) system and the CRISPR-associated proteins (Cas) make up an adaptive immune mechanism used by many bacteria and archaea to protect themselves from invading genetic material. Despite the immense evolutionary advantage of the CRISPR-Cas system, it must be meticulously regulated as it has the potential to target endogenous genes and damage the host organism. Identifying the main regulators involved in this process and how they are influenced by distinct conditions are of great clinical interest, since this prokaryotic defense system can be exploited for genome editing and therapy development. This review aims to elucidate the regulation of the CRISPR system in bacterial communities—upon quorum sensing and alginate production in biofilms—and in stressed conditions—upon antibiotic treatment or induction of the Rcs response. Despite the intrinsic contradictions of the results gathered in this review, growth rate is identified as a potential unifying regulator of CRISPR immunity. Overall, the regulation of the CRISPR-Cas system is shown to be multi-dimensional and cross-sectional, to greatly vary amongst lineages, and to be highly sensitive to conditional changes.

Sc(OTf)3 CATALYZED DEHYDRATION OF 2-(HYDROXY(PHENYL)METHYL)PHENOL TO ortho-QUINONE METHIDE: A MOLECULAR ELECTRON DENSITY THEORY STUDY
Authors: Soleymani M. , Goudarzi M.
Published: March 2023

In this work, a MEDT study is carried out on the dehydration of 2-(hydroxy(phenyl)methyl)phenol HPMP to the corresponding ortho-quinone methide OQM experimentally reported by Tang and coworkers. Both catalyzed and uncatalyzed reactions were studied and it was found that Sc(OTf)3 reduces considerably the activation barriers. The catalyzed reaction takes place initially by the formation of a stable molecular complex between the Sc(OTf)3 Lewis acid and HPMP. The structure of this complex was studied by using MEP map, IGMH and QTAIM analyses and it was found an ionic interaction between the Sc atom and the oxygen atom of HPMP. The electron transfer calculations indicated that the catalyzed reaction is highly polar which is probably responsible for the significant reduction of the activation barriers and consequently performing of the reaction at room temperature under experimental conditions. Finally, the molecular mechanism of the reaction was investigated by ELF analysis and it was concluded that the cleavage of the C4-O5 bond is taken place by polarization of the bonding electron toward the O5 oxygen atom in the first half of the reaction.

We report progress in the European Union/European Economic Area (EU/EEA) towards the Sustainable Development Goal target for tuberculosis (TB) and for the associated global/regional targets. The TB notification rate and the number of TB deaths declined since 2015 but, if current trends continue, the EU/EEA will not reach the 2030 targets. Performance on treatment initiation targets declined sharply during 2020–2021, while the percentage of TB cases with successful treatment outcomes remains low, at 47.9% of the multidrug-resistant TB cases.
Active tuberculosis screening among the displaced population fleeing Ukraine, France, February to October 2022
Authors: Guthmann Jean-Paul , Fraisse Philippe , Bonnet Isabelle , Robert Jérôme
Published: March 2023

Persons fleeing Ukraine since February 2022 have potentially higher risk of tuberculosis (TB) vs all European Union countries. Interest of active TB screening among this population is debated and not widely adopted. In this screening intervention by a network of TB centres in France, the number needed to screen (NNS) was 862 to find one case. This experience shows that this strategy may be relevant for TB control in situations of massive displacement, similar to that following the Russian invasion.

V.I. KRYZHANOVSKYA’S FICTION AND THE RISE OF POPULAR OCCULTISM IN LATE IMPERIAL RUSSIA
Authors:   Russian State University for the Humanities, Razdyakonov Vladislav S.
Published: March 2023

The article aims to examine V.I. Kryzhanovskaya’s literary work as a means by which representatives of the occult environment introduced the general public to the diversity of occult doctrines. Based on archival and published sources, the article delineates the occult preferences of V.I. Kryzhanovskaya, describes the phenomenon of popular occultism in the context of the occult market in Russia in the late 19th – early 20th century, offers a definition of “occult novel” and reveals its understanding by occultists as a means of spreading occult views. The artistic space of fantastic literature is defined as a space alternative to the spaces of both reality and fantasy, and claiming to perform a mediating function between subjective and objective experience. The author suggests that fiction for the occult served not only as an artistic means of transmitting views, but also as an ideal artistic medium, allowing the question of the reality of occult phenomena to remain open, leaving the final decision to the reader
VOTIVE GIFTS IN PRESENT-DAY RUSSIA. RELIGIOUS PRACTICE IN THE DYNAMICS OF ITS DEVELOPMENT
Authors:   Russian State University for the Humanities, Antonov Dmitrii I.
Published: March 2023

The article discusses votive gifts that are relevant to the contemporary Russian temple environment. The rapid revival and spread of the votive tradition in post–Soviet Russia is one of the most striking phenomena of religious culture in recent decades (along with practices related to the appropriative strategy and the active spread of “Orthodox nomadism”, pilgrimage tourism). The variety of gifts and related practices, discussions around that phenomenon, and different options for its moderation by clerics and church workers indicate that the tradition has turned out to be one of the most lively and in demand; it is relevant among different social groups – parishioners, pilgrims, occasional visitors to churches. The author reviews modern offerings, typologizes votive gifts (characteristic and rare, which have spread since the 1990s and have appeared in recent years), analyzes their connection with the icons being gifted. The focus of attention is also on the attitude of clerics and church workers to offerings; on the practice of distributing gifts in the church space (storage, hanging etc.). The analysis is based on interviews collected in 2018–2022s in the churches in dozens of cities in different regions of Russia
THE CHURCH AS A SPACE OF IMAGES IN PICTURESQUE PROSKINETARIUMS. A VISUAL PROGRAM FOR THE PILGRIM
Authors:   “ART-expertise”, Zlotnikova Irina V.
Published: March 2023

The author researches the theme of the facial pictorial proskinitariums – jerusalemija. They were the manifestations of hierotopia, reflecting the sacred topography of the Holy Land within the iconic space. At the same time the jerusalemija visualized the pilgrim’s journey in the Holy Land in the 18th – early 20th centuries through images available to the pilgrim. The name of the place was visualized by creating an associative pictorial symbol, while the visual image was often supported by text referring to the lines of the New or Old Testament. The iconography of ‘jerusalemija’ dates back to the engravings of Western European masters of the 16th – 17th centuries and to the engravings of illustrators of printed proskinitariums (“walks”), for example, Christopher Zhefarovich. Traditionally Palestine and in particular Jerusalem was the center for the production of “jerusalemija”, also known as the pilgrim’s icon-eulogy “Topography of the Holy Land”. When studying the published monuments from foreign and Russian collections, the author identified the main iconographic types of “jerusalemija”, originating from different protographs: 1) “jerusalemija” as a map-icon, where the topography is primary, and the prayer image is secondary; such a type existed in a small and expanded versions; 2) “jerusalemija’ is a prayer image (souvenir icon for pilgrims) that consisted of two subgroups that differed in the degree of significance of the prayer component and the presence of topography. That group of sources includes a rare image from a private Russian collection, which was not painted in the workshops of Palestine, but executed as a copy of the eulogy icon by an iconographer of one of the Chernigov monasteries in the middle of the 18th century. The author analyzes its program and iconographic features. The paper is also focused on the iconographic schemes of various groups of “jerusalemijas”, and reveals their characteristic features and specifics as a hierotopic project

Published: March 2023

The article is about the tradition of creating handmade icons with foil rizas in the village Lipovka, located in the Ardatovsky district in the south-west of the Nizhny Novgorod region. The focus is on the genesis of the “flower tradition” of decorating Ardatov icons and on its comparison with other artistic styles in the Nizhny Novgorod Southwest. Also, they study the memories of local residents about Raisa Vasilyevna Serova the craftswoman icon-painter from the village of Lipovka. Cultural and historical origins of the Ardatov tradition of decorative and applied crafts. A hypothesis has been put forward about the presence of the Mordovian ritual substrate in the traditions of decorating foil icons in 20th century. To substantiate it, data from the more eastern districts of Nizhny Novgorod Oblast (Diveyevsky and Pervomaisky), as well as from the Republic of Mordovia are presented. According to these data the same practices of decorations with bright paper flowers were preserved in relation to pre-Christian ritual artifacts in the wedding rites of the local Mordva-Erzya (wreaths and ceremonial pies) until the end of the 20th century It is assumed that such more archaic ritual practices of the Mordva could be transferred to Christian ritual artifacts after they adopted Christianity in the 18th century. The authors describe the artistic techniques of the Ardatov icon tradition, characterize the artistic manner of a craftswoman from the Ardatov village of Lipovka and describe the religious landscape of that village during the Soviet era.

Special assessment of working conditions for winter maintenance of roads and sideways
Authors: Degaev Evgeniy , Volodina Anastasiya , Makarov Oleg , Lunyakov Mikhail
Published: March 2023

When processing roads and sidewalks, safety and labor protection requirements are often violated. There is a constant excess of the concentration of anti-icing reagents (AGR), the components of which at maximum concentrations adversely affect the human body. In particular, blood parameters, as well as the most important organs, such as the liver and kidneys, are affected. The concentration of AGR per unit area determines the intensity of the harmful effects of substances on the human body. The penetration of harmful substances into the human body occurs by airborne droplets or skin-resorptive action and depends on the method of distribution of AGR and the level of mechanization. The probabilities of the occurrence of a dangerous event when working with AGR, its severity and risk level are determined. Recommendations are given for employees involved in the treatment of residential and public areas with anti-icing materials.
Methodological approaches to determining labor costs in the design of construction projects
Authors: Korol Elena , Akopyan Galina
Published: March 2023

The life cycle of buildings includes the labor costs of all categories of management and construction personnel involved in construction from the beginning of preparatory work to the commissioning of the facility. Additionally included here are the costs of developing project documentation. Qualitatively developed project documentation leads to a positive result of construction activity. The price of design works is determined based on the following costs: personnel labor costs, insurance payments, expenses for all types of repairs, material costs, maintenance of buildings and/or rent, taxes and fees. A competent assessment of labor costs and their systematization will help to identify promising segments of labor cost optimization that most significantly affect the reduction of total labor costs.
Clastic Plays in The North East Natuna Basin
Authors: Mulyono D.H.
Published: March 2023

The East Natuna Basin comprises several sub-basinal areas which formed during the Tertiary as a result of extension relating to the opening of the South China Sea during the Oligocene and Early Miocene. Several small Oligocene half-grabens occur in the northern part of the area close to where the Tuna Block is located. They have a NE-SW trend and the sediments are relatively uniform in thickness, less than 2,600 ft thick, with regional thickness growth to the east towards the basin center. However in the Lower Miocene a more pronounced extensional episode enlarged the existing half grabens and generated large growth fault related sediment packages consisting predominantly of clastic sequences. Marine conditions in the Mid Miocene gave rise to carbonate development which continued to the latest Miocene with some very large reef related carbonate build-ups observed on seismic. In Late Miocene this area underwent further deformation caused by right lateral transtension which produced numerous NE-SW normal faults. This was then followed by a period of quiescence and deposition of the overlying Pliocene Muda Formation marine shales and clastics. The tectonically controlled, locally thick sequences of the Oligocene and Lower Miocene sediments indicate good potential for source and reservoir/seal pair rocks. Exploration in the East Natuna Basin began in the 1970’s, mainly targeting the Terumbu Formation carbonate buildups, which were easily mapped on the available 2D seismic data. Some discoveries were made and the most significant of which was the supergiant D Alpha gas field discovery by AGIP in 1973 containing over 220 TCF including +/- 71% CO2. However, the underlying clastics were not well imaged by the 2D seismic data and many of the wells drilled were not optimally located for testing the underlying Arang and Gabus clastic sections. The discovery of hydrocarbons in the Gabus and Lower Terumbu clastics in the Kuda Laut-1 and Singa Laut-1 wells by Premier Oil in 2014 confirmed the exploration potential of these intervals. The discoveries now known as the Tuna Field were appraised by two additional wells in Q3-Q4 2021 confirming the presence of rich wet gas with a high condensate yield, but also encountering oil rims, to the previously discovered gas columns. The main reservoirs are Lower Terumbu shallow marine bioturbated shaly sandstones in the Kuda Laut hanging wall structure and Gabus fluvial channel sandstones in the Singa Laut footwall structure. These two reservoirs exhibit very different properties as indicated by conventional cores, extensive wireline data and the DST’s. Post well analysis is ongoing to further characterize these reservoirs and the fluids contained, the results of which will be critical for the commercial development of the Tuna field.
Santan Delta Evolution and Its Implication to The Petroleum System in North of Kutei Basin

The presence of delta between Mahakam Delta and Sangatta Delta has been discussed before by several authors in Kutei Basin. However, there is no detailed information of its location and stratigraphic successions. Our recent sequence stratigraphic studies, utilizing multi vintage seismic and well-based data in East Kalimantan & Attaka Working Area, provide new insights into the evolution of Santan Delta and its implication to the petroleum system in our working area. The Santan Delta might have been overlooked as a potential sediment source for reservoirs in the north of Mahakam Delta. Since the 1970’s, more than 50 MMBOE of hydrocarbons have been produced in this area from Late Miocene – Pliocene deltaic reservoirs. Santan Delta development started in early of Late Miocene which was indicated by fluvio-deltaic sedimentation prograde to the east. Kuching High to the west of the delta started to undergo uplift. Santan Delta development achieved peak sedimentation at the end of Late Miocene – Early Pliocene which was indicated by the presence of significant deltaic facies. It also pushed the carbonate sedimentation to the shelf margin area. Later in Late Pliocene, the presence of Santan Delta started to diminish which is shown by presence of shelfal carbonates that retrograde or backstep to younger shelf margin in this area. The stratigraphic succession of the Santan Delta deposited in Late Miocene – Pliocene became important to better understand source rock, reservoir, and seal distribution in its surrounding deltaic, shelf, slope, and deep-water environments.
Lower Miocene Petroleum System in The Upper Kutai Basin - A Hidden Potential
Authors: Nugroho B.
Published: March 2023

Hydrocarbon exploration and production efforts have been carried out in the Lower Kutai Basin, focusing on Mio-Pliocene reservoirs for more than a century. An estimated total of 5 BBL of oil and 60 TCF of gas resources have been discovered to date. The western area close to the basin margin or the so called ‘the Upper Kutai Basin’ is relatively under explored. The Medco Energi operated Kerendan Field is the first and the only Oligocene carbonate gas field in the basin. Exploration in the Upper Kutai Basin was initially focused on Paleogene Plays; the Eocene syn-rift and Oligocene carbonate plays. In contrast, the Miocene Play was not considered promising because the sediment was mainly eroded and exposed to the surface. Furthermore, the absence of any Lower Miocene commercial discoveries in the Kutai Basin puts a high exploration risk on any Lower Miocene Play target. The recent exploration in the Greater Bangkanai area has revealed a Lower Miocene potential. The reservoir of this play is older than the current producing sandstones in the fields to the east which are Late Miocene to Pliocene in age. The Kerendan development wells that penetrated the Miocene section, together with the new data from 2D seismic acquisition, Full Tensor Gravity (FTG) survey, surface geological mapping and microseepage geochemical analysis have significantly improved our understanding on Miocene Petroleum system. The prospective Miocene Play exists in the Kerendan Deep, a local depocentre in Bangkanai that has not suffered extensive uplift and erosion. The Miocene Play consist of Lower Miocene deltaic sandstones, with associated deltaic coals and carbonaceous shales. The potential reservoirs and source rocks are in places hence make a self-hydrocarbon sourcing system. The structural trapping mechanism is a 3-way dip closure on inverted thrust fault system that was covered by Lower Miocene intra-formational shales. A recent finding of a live oil seepage from an old coal well has directed our attention to an active Lower Miocene petroleum system. The results of an airborne FTG survey were integrated into the interpretation to complement limited and sparse 2D seismic and well data. The integrated study concluded that the NW-SE and W-E Lower Miocene delta system was developed in the southern margin of the Kutai Basin as shown by the Gross Depositional Environment (GDE) map. Petroleum system modeling suggests that the hydrocarbon expulsion occurred after the structural trap formation.. Furthermore, a fault seal study resulted in a high estimated SGR (shale gouge ratio) which may suggest that the fault trap is sealed. Despite a sparse and relatively poor quality existing 2D data set gives a relatively low confidence level on trap validity, all of other essential components for a working Miocene petroleum system are present in the Greater Bangkanai area. Therefore, further exploration program should be focused on confirming structural trap size and geometry to reduce the wide range of uncertainty.
Leveraging Unsupervised Machine Learning on Seismic Images of Miocene Deposits in the Carpathian Foredeep Basin for Facies Classification

Published: March 2023

The application of machine learning (ML) in seismic interpretation has become widely shared in geosciences, and this is due to its ability to be accurate, robust, and inexpensive. Using seismic attribute variety, the geological feature of subsurface data could be recognized in detail, where data can be presented in various physical properties depending on the purposes. However, manual interpretation could be time-consuming and take much effort. Therefore, machine learning is a robust method in determining facies on seismic data utilizing computer intelligence capabilities with minimal human intervention and a short time. Unsupervised learning when used can identify a pattern without a learning process. In other words, the data will separate itself automatically based on the method used without any labeling. In this research, we used the Gaussian Mixture Model (GMM) and K-Means Clustering methods to classify the distribution of facies in seismic images. The Gaussian Mixture model is defined as a model-based probabilistic formulation utilizing the number and shape of clusters determined in a more objective way using a Bayesian framework taking into account the possibility and complexity of the model. In contrast, K-Means Clustering is an iterative algorithm that is capable to group data into features or variables which has a similar characteristic, with K as a cluster having the nearest means. The primary motivation of this research is to increase our understanding of unsupervised machine learning, including the Gaussian Mixture Model (GMM) and the K-Means Clustering method for facies classification. These two methods were applied to selected seismic attributes with a target zone in the Miocene gas-rich formation, Carpathian Foredeep Basin, Poland. All these attributes have different parameters that might be correlated, and thus, to increase their statistical values, we applied Principal Component Analysis (PCA) as the dimensionality reduction tool. The key takeaways are on the distribution of sandstone, mudstone, and shale facies, where we identified that the Gaussian Mixture Model provides more convincing results than K-Means Clustering in the sandstone formation containing gas, which can be indicated as one group unit of a cluster.
The Pematang Group Sand Analysis Using Growing Neural Network Machine Learning

Published: March 2023

The Central Sumatera Basin (CSB) is one of Indonesia's giant mature basins and attractive hydrocarbon producers. P.T. Badan Operasi Bersama - Bumi Siak Pusako (PT.BOB-BSP) company has several 3D seismic surveys in CSB that are of old vintage but still provide important data for seismic reservoir analysis in exploring lacustrine sediments of the Pematang Group, one of the most challenging reservoirs that produce hydrocarbons. In order to optimize seismic data for reservoir characterization of the Pematang Group, adequate seismic interpretation tools are needed, especially with the help of the latest technology to find optimal locations for well placement and help increase oil production by exploring and exploiting hydrocarbon in this area. Some of the latest technologies that can be applied to find new insights from old seismic data are using the Growing Neural Gas (GNG) algorithm clustering techniques and volumes visualization technology. GNG can be used for clustering to organize a collection of k-dimensional vectors into groups whose members share similar features for 3D seismic volumes of data, significantly clustering the quality of reservoir sand and anomalies in lacustrine sediments of the Pematang Group. This study aims to use GNG clustering techniques for reservoir characterization in 3D seismic surveys using data from the CSB. The workflow consists of three main phases: preparation, execution, and delivery. The first phase consists of collecting, cleaning, and preprocessing seismic, wells and interpretation data. Once the preparation is considered satisfactory, it will be followed by the execution, starting with data processing, clustering, and validation. GNG clustering methods were deployed to build a facies volume based on three seismic attributes inside the interval of the Pematang Group. After the facies model was satisfactory, a facies map was extracted from the facies volume along the Pematang Zone to generate a facies distribution map. The last step is to validate the facies extraction map of the facies model with the existing well log data and check the accuracy based on the well log result. Once the validated results are satisfying, the workflow status will change from execution to the delivery phase to create the final project conclusion and presentation. This study demonstrated excellent prediction to image or model seismic facies as facies volumes. This facies model allows for classifying and identifying the Pematang sand distribution for reservoir characterization analysis. It provides new insights and optimal locations for exploration drilling targets more effectively, increases drilling success and reduces cost and risk for optimizing exploration hydrocarbon strategy in Pematang Group.
