A Review on the Energy Performance and Efficiency of Radiant Floor Heating Systems with Integrated Phase Change Materials
Authors: Brănoaea Marius , Burlacu Andrei
Published: February 2022

In the modern society the concept of energy efficiency of buildings has become a subject of great interest, due to the negative impact of buildings upon the environment, society and economy. One of the methods of overcoming this is to provide a better efficiency of the energy storage because it is the key to resolve the difference between supply and demand. In comparison to electro-chemical batteries which provide limited energy storage at a high financially cost, thus in this regard, thermal energy storage technologies with high energy density have increased market potential. PCMs present objective advantages in comparison to classic construction materials due to their characteristics of being able to store and release higher quantities of thermal energy during the phase change process. A PCM radiant floor heating system can provide a reduction of the energy consumption for heating by up to 43%, trough the higher discharge time of the PCM compared to regular heating systems.

Authors: Nanea Dana-Ramona
Published: February 2022

The purpose of the research carried out is to develop a new perspective on a material resulting from steelworks. Currently, the blast furnace sludge from Galati is used as granular material in road construction generally at foundation layer. The bf sludge has the chemical and mechanical potential to be used as filler in bituminous mixture, as a result of its particular composition which does not interact with bitumen, and it has the ability to be crushed in particle fractions. The main constituents of the bf sludge are different oxides, as calcium, aluminium, iron, magnesium, manganese oxides, sulphide. The raw material is homogenous, with no impurities and it is not toxic for the environment. The characteristics of the filler sample was analysed, and its results is compared with standard specifications. The bf sludge was ground into very fine granules, under 2 mm, and then tested in laboratory in standard conditions.

Authors: Micu Marian Bogdan , Adam Maricel , Andruscă Mihai
Published: February 2022

The paper presents a possibility to determine the electrical patterns for the electrical loads through nonintrusive monitoring of their operating regimes.

The electrical patterns are determined on the basis of the electrical parameters acquired for each load from the electrical network analysed. The determination of the electrical patterns is useful for the management of electrical energy consumption.

The easiness of the nonintrusive monitoring technique is determined by the possibility of acquiring the electrical parameters from a single measurement point from the electrical network. From the electrical parameters acquired can be obtained information for electrical loads consumption recognition and their operating regimes, for certain time intervals, and it can be established the technical condition for each load.

Published: February 2022

The discharge of wastewater containing both high salinity and high organic content without prior treatment is detrimental to aquatic life and water hygiene. In order to integrate the advantages of membrane treatment and biological treatment, and exert the phosphorus removal efficiency of dewatered alum sludge, in this study, an aerobic membrane reactor based on dehydrated alum sludge was used to treat mustard tuber wastewater with salinity of 6.8-7.3 % under the conditions of 30 °C, 20 kPa trans-membrane pressure (TMP) and chemical oxygen demand (COD) of 3300-3900 mg/L. Three replicate reactors were applied to assess the operational performance under different organic loading rate (OLR). The results showed that all reactors were effective in removing COD, ammonia nitrogen (NH4
+-N) and soluble phosphate (SP) under the conditions of 30 °C and 20 kPa of TMP. Meanwhile, the effluent concentration of COD, NH4
+-N and SP all increased while OLR was changed from 1.0 to 3.0 kg COD/m3/day, and the effluent COD and NH4
+-N concentration except for SP could reach the B-level of Chinese “Wastewater quality standards for discharge to municipal sewers” when OLR was less than 3.0 kg COD/m3/day. This indicates that dewatered alum sludge-based aerobic membrane reactor is a promising bio-measure for treating high salinity wastewater.

Published: February 2022

Objective. Carbamazepine (CBZ), a widely used antiepileptic drug, is one major cause of the idiosyncratic liver injury along with immune reactions. Conversely, prostaglandin E2 (PGE2) demonstrates a hepatoprotective effect by regulating immune reactions and promoting liver repair in various types of liver injury. However, the amount of hepatic PGE2 during CBZ-induced liver injury remains elusive. In this study, we aimed to evaluate the hepatic PGE2 levels during CBZ-induced liver injury using a mouse model.

Methods. Mice were orally administered with CBZ at a dose of 400 mg/kg for 4 days, and 800 mg/kg on the 5th day.

Results. Plasma alanine transaminase (ALT) level increased in some of mice 24 h after the last CBZ administration. Although median value of hepatic PGE2 amount in the CBZ-treated mice showed same extent as vehicle-treated control mice, it exhibited significant elevated level in mice with severe liver injury presented by a plasma ALT level >1000 IU/L. According to these results, mice had a plasma ALT level >1000 IU/L were defined as responders and the others as non-responders in this study. Even though, the hepatic PGE2 levels increased in responders, the hepatic expression and enzyme activity related to PGE2 production were not upregulated when compared with vehicle-treated control mice. However, the hepatic 15-hydroxyprostaglandin dehydrogenase (15-PGDH) expression and activity decreased significantly in responders when compared with control mice.

Conclusions. These results indicate that elevated hepatic PGE2 levels can be attributed to the downregulation of 15-PGDH expression under CBZ-induced liver injury.

Phaeochromocytomas are catecholamine-secreting tumors arising in the chromaffin cells of the adrenal medulla. They are a rare cause of secondary hypertension. However, catecholamine secreting tumors may also be found in the extra-adrenal sites, producing similar symptoms as the adrenal phaeochromocytoma. The extra-adrenal phaeochromocytomas, are referred to as paragangliomas (PGLs). About 75% of extra-adrenal phaeochromocytomas are intra-abdominal, mostly located in perinephric, periaortic, and bladder regions. Most phaeochromocytomas secrete excessive amount of epinephrine and norepinephrine, whereas most paragangliomas secrete only norepinephrine. The excessive secretion of these products could lead to paroxysms of symptoms that could be life threatening. Medical management is initially offered, but definitive treatment involves surgical removal of the tumor, which requires promptness on the both the clinician and the patient sides. We present a case of an extra-adrenal phaeochromocytoma in an adult male with revealing imaging of a mass surrounding the bladder. The patient was managed with both alpha- and beta-adrenergic blockers. He declined the surgery and eventually died after appearing in an acute hypertensive crisis.

Authors: Marišová Eleonóra , Valenćiková Marina
Published: February 2022

In the waste sector, EU Member States implement EU legislation. They rely on EU Directives and their waste legislation and policies. During the evaluated period (2015–2021), the Slovak Republic amended the Waste Act 79/2015 Coll. and issued strategy papers following EU legislation. France adopted its National program for prevention of waste and Finland its National waste management plan. In our research, we use a method of comparison and analysis of selected legislative documents to examine the achievement of the Green Deal’s objectives in the Slovak Republic and selected EU countries. We have shown the legislative process results through research, which indicate the achievement of set waste management goals. In our future research we will focus on building waste management infrastructure in the EU since it is necessary to apply the idea promoting the support of such waste treatment facilities that will be sustainable throughout their existence.

Blessing and curse of crowdsourcing among educational experts - a study of teachers’ willingness to contribute as a crowd
Authors: Girshin Rina Zviel , Gajek Elżbieta
Published: February 2022

Crowdsourcing is a new technique of gathering data or performing large scale tasks by outsourcing it to a wider public. Its role and potential in language education is investigated in first in its volume research - enetCollect (European Network for the Combination of Language Learning and Crowdsourcing Techniques) COST project. This paper presents the most pertinent data about highly successful crowdsourcing portals for language learning, some educational projects based on teacher’s contributions and analysis of a survey as a crowdsourcing activity. The paper analyses two surveys: a low response rate, large scale pan-European survey wherein a sample of language teachers od all station all over Europe was asked to answer some crowdsourcing related questions (Arhar Holdt et al., 2020) and a high response rate, small scale, survey among the distributors of the first survey in which they were asked to analyse the numbers and techniques they used to reach the crowd. The focus of this article is on an extension study to the teacher survey in which thousands of teachers were approached but the response rate was relatively low. While such low response data in other cases would have been perceived as a drawback and are rarely analyzed, in the context of crowdsourcing meta research this could be a goldmine of importance. The article demonstrates how educators mayor may not be willing to participate in a crowdsourcing activity.
Time in literary translation: Anticipation of retrospection, temporality of reading and living
Authors: Fentaw Alebachew , Dagnew Tesfaye , Guadu Ayenew
Published: February 2022

Aiming at explicating structural prolepsis, and how temporality of reading and living are related, the study was conducted on Tell Me Your Dreams (1998) and its respective Amharic translation (Hilimishn Achawichgn-ህልምሽን አጫውችኝ, 2009).The English novel is anticipation of retrospection. The structural prolepsis propels the story without excursion. But the Amharic translation is not; there is no structural prolepsis. The present is constructed retrospectively and reveals that the best of times is yet to come in the English novel; the future has a retrospective significance of meaning to the present. There is a hermeneutic circle between the presentification of reading the English novel and the depresentification of real life present. The present of the English novel and the lived present of real life are experienced in preterite form in relation to a future to come. The future of real life and the English narrative are the same for both are unknown and imagined. The A and B philosophy of time solidified the literariness of the English narrative, but temporal becoming is emphasized in the Amharic translation. The past has just been, and so is not; the future is to be, and so is not yet. Thus, its literariness can’t be sensed.

Published: February 2022

The lime plasters of the excavated monument of Salvankuppam, previously submerged and exposed by the Tsunami occurred in the Indian Ocean on 26th December 2004 was studied with different analytical techniques. The temple is dated 4-5th century CE. The XRF, XRD, FTIR, NMR, SEM-EDX analysis of the lime plasters evidenced particular occurrence of phosphatised bacterial remains in saline conditions. The formation of amorphous Ca-phosphate by bio mineralization was identified in the plasters by the analyses. The plasters are made of air-lime with coarse aggregates and seashells inclusion as confirmed by the thermal and chemical analysis. The microstructure and morphological investigations of mineralized microbial structures by SEM-EDX indicated the formation of amorphous Ca-phosphate. The unordered and fibrous spherulites have hardened and reduced porosity of the plaster by bio mineralization as observed through MIP analysis. The 16S rRNA sequencing has identified the Pseudomonas strains mainly responsible for the clustering of amorphous Ca-phosphate particles around the bacterial colony.

Published: February 2022

Acute myelogenous leukemia is a multi-step hematological malignancy, affecting function, growth, proliferation and cell cycle of myeloid precursors. Overall assessment of patients with the disease requires among everything else, a comprehensive investigation of the genetic basis through various methods such as cytogenetic and molecular-genetic ones. This clarification provides diagnostic refinement and carries prognostic and predictive value in respect of essential therapeutic choices.

With this review of the literature, we focus on summarizing the latest recommendations and preferred genetic methods, as well as on emphasizing on their general benefits and limitations. Since none of these methods is actually totipotent, we also aim to shed light over the often-difficult choice of appropriate genetic analyses.

Main aim of the paper is to use a single non-metric camera to support the determination of the position of. Authors propose to use the existing infrastructure of CCTV cameras mounted on bridges and wharves to determine the position of inland waterway vessels. Image from cameras giving the pixel coordinates of moving object is transformed to the geodetic data domain using a modified projective transformation method. Novel approach is to use of Sequential Projection Transformation (SPT) which additionally uses virtual reference points. The transformation coefficients calculated using the virtual points are used to determine the position of the vessels and are also simultaneously used to calibrate the industrial camera. The method has been verified under real conditions, and the results obtained are average 30% more accurate compared to the traditionally used projective transformation using a small number of real points.
A New Method to Boost VoIP Performance Over IPv6 Networks
Authors: Abualhaj Mosleh M. , Al-Khatib Sumaya N.
Published: February 2022

The demands on virtual communication have increased noticeably during the COVID-19 pandemic lockdown. As an essential part of virtual communication, VoIP should be promoted to achieve the desired level of performance. One critical area investigated in VoIP is the bandwidth utilization (BWU) of the VoIP over IPv6 networks. Enhancing BWU will impact call capacity and quality; it increases call capacity and boosts call quality. Unfortunately, a considerable amount of bandwidth is wasted when running VoIP over IPv6 networks. This is due to the large size of the IPv6 header and the small size of the speech frame. This paper proposes a new method to handle the inefficient BWU when running VoIP over IPv6 networks. The proposed method combines multiplexing multiple VoIP packets in one IPv6 header and using the superfluous fields to carry a portion of the speech frame. Therefore, the proposed is called packet multiplexing and carrier fields (PMCF). Investigation of the PCMF method has been done using four metrics to measure the promotion in BWU, namely calls capacity, header size, bandwidth saving, and speech frame shortening metrics. With the four metrics, the PMCF method has outperformed the comparable methods. For instance, the call capacity has been promoted by up to 269% compared to the typical IPv6 method in the tested scenarios. Therefore, the PMCF method is a feasible solution to facilitate the BWU of VoIP when running VoIP over IPv6 networks.
Efficiency of Ship Operation in Transportation of Oversized and Heavy Cargo by Optimizing the Speed Mode Considering the Impact of Weather Conditions
Authors: Onyshchenko Svitlana , Melnyk Oleksiy
Published: February 2022

Prior to commencing the voyage planning procedure, the entire navigation area on the forthcoming passage should be divided into several sections, depending on various factors, such as traffic density, restricted depths, availability of ship reporting systems, hydrometeorological conditions, high risk navigation areas in order to outline measures to ensure the safety of ship’s navigation. In addition, these factors have direct impact on the ship’s speed during the voyage. On the other hand, slow steaming can reduce fuel consumption on the same section of the route by 10-15%. Reducing the ship’s speed can significantly minimize its operating costs. However, when choosing economically feasible ship’s speed it should be kept in mind that reducing the speed can lead to a significant decrease in the number of voyages per year and, consequently, to the reduction of annual freight income. Therefore, a practically important and relevant problem is the necessity to find the speed of ship operation, which will provide a balance between economical fuel consumption and profits from ship operation. The classic approach to optimizing the speed mode of ships is based on the cubic dependence of fuel consumption on speed. Therefore, depending on the distance between ports, the duration of the voyage and the conditions for the time of arrival of the ship to the port, in the modern publications were proposed approaches to the optimization of the speed mode, based on the additional income or time-charter equivalent.
Competence of Bus Rapid Transit Systems Coupled with Transit Signal Priority at Signalized Junctions
Authors: Desta Robel , Tóth János
Published: February 2022

One of the primary causes of poor public transport performance is delays at intersections. Among the efficient and sustainable solutions to boost mass transportation performance, Bus Rapid Transit (BRT) consists of infrastructures integrating dedicated bus lanes and smart operational service with different ITS technologies like Transit Signal Priority (TSP). This research studies the competence of buses operating on junctions of the BRT corridor where they have Signal Priority on the dedicated lane. The studied intersection is located around the center of the Addis Ababa BRT-B2 line, which is relatively gentle grade and characterized by the high traffic and pedestrian volume. Microscopic models were created for the chosen intersection, along with possible calibration and validation; moreover, a statistical comparison was performed to evaluate different scenarios with the goal of displaying the deployment benefits. To assess the performance of BRT buses and their overall influence on general traffic, scenarios with and without TSP were evaluated. PTV VISSIM and the VisVAP add-on simulation program were used to examine TSP alternatives. Incorporating TSP reduced the travel time by up to 4.78% in the priority direction, the average travel speed increased by 7.25%, and the queue length also reduced by a maximum of 6%, whereas in the non-priority direction, the queue length increased by a maximum of 2.5%. Moreover, the overall average passenger delay has reduced by an average amount of 15%. One of the simplest ways to improve transit performance could be signal priority strategies, which has a minor influence on the general traffic.

Establishment of the model of positive bilateral cooperation in the Russia-Japan dialogue after the end of the Cold War: analysis of negotiations tactics in the 1990s
Authors: Malashevskaya Maria Nikolaevna
Published: February 2022

This article analyzes the establishment of mutually beneficial model of the dialogue between Russia and Japan in the context of implementation of new negotiation tactics on the bilateral level in the late XX century. Particular attention is given namely to the tactics that are considered as the basis for the formation of partnership between the countries since the end of the 1980s. Intensification of the dialogue between Russia and Japan in the 1990s contributed to alignment of the parties in seeking the grounds for the development of mutually advantageous relations. The application of the instruments of face-to-face negotiations and informal meetings can be viewed as an indicator of alignment of the parties, a desire to propel the bilateral cooperation to a fundamentally new level, which is proven by the provisions of the “Moscow Declaration on the establishment of a constructive partnership between the Russian Federation and Japan” of 1998, which has become the framework for collaborative actions in the new century. The article discusses the most common tactics and methods applied in the negotiations between Russia and Japan, although its it not an exhaustive list of all possible techniques. The scientific novelty consists in systematization and description of the tactics of Japan’s diplomacy that were practically implemented in Russian in the 1990s and remain relevant to the present day. Personal contribution of the politicians and diplomats into creation of the foundation for multidimensional cooperation between Russia and Japan was of crucial importance. Analysis is conducted on the activity of Japanese diplomats Tamba Minoru, Edamura Sumio, Togo Kazuhiko, as well as politicians Nakayama Taro, Hashimoto Ryutaro, Obuchi Keizo, and Mori Yoshiro, who played the role of the political architects in Tokyo with regards to Russia. The works published by them are a valuable source for the analysis of the events under review.

Authors: Kovalevskaia Natalia  Vladimirovna , Tikhotskaia Maria  Anatolievna , Shevchenko Yan Nikolaevich
Published: February 2022

The COVID-19 pandemic and coronacrisis have clearly exposed the strong dependence of modern companies on the approaches towards data management, stability of information networks and digitalization, as well as significantly strengthened the assertion of the Europeans in the need to achieve strategic autonomy with regards to development of the own digital solutions. The article aims to determine the place of the European Union in the international information and communication space in the context of global data management policy. Research methodology leans on the principles of the multi-paradigm method used for extrapolating some provisions of Robert Gilpin’s hegemonic stability theory on the modern technological competition among the countries on the international arena within the framework of regional approach. The article examines the term “information sovereignty” based on the principles of international law in a constantly changing international environment. The research addresses such documents as “New Industrial Strategy for Europe”, “European Data Strategy”, and the decision of the European Court of Justice concerning the Transatlantic Privacy Shield Agreement. As an example of the European digital policy, the author examines the ambitious GAIA-X project intended to create an open digital ecosystem and develop common requirements for the European data infrastructure. The article formulates the recommendations aimed at ensuring effective management in the digital sector, and offers the model of multilateral participation, which would allow reaching information sovereignty based on the European values and ideals.
Cultural-philosophical comprehension of O. Spengler's "Decline of Europe" in Chinese thought of the early XX century
Authors: Sukhomlinova Viktoriia
Published: February 2022

The object of this research is the tradition of comprehension of cultural identity in China of the early XX century. The subject is impact Oswald Spengler's "Decline of Europe" upon this tradition. There are multiple mentions of Spengler in the articles and essays of Chinese students who studied in Germany in the early 1920s; by the 1930s, his views underlay the cultural concepts developing in China. In the Chinese historical studies of later period, the publication of "Decline of Europe" appears near equal in importance to the World War I. This article aims to determine why the experience of Spengler's Eurocentric concept turned out to be so profound in the alien Chinese culture, and which means can be used for analyzing such experience within the framework of the philosophy of culture. The conclusion is made that the influence of the "Decline of Europe" upon Chinese thought dedicated to the questions of culture was multidimensional. On the one hand, the very fact of the emergence of "Decline of Europe" within the Western philosophical tradition was significant for Chinese intellectuals. Against the background of crisis of the strategy of all-round Westernization of Chinese society, the "Decline of Europe" became the so-called legitimation of the reasoning on "Chinese culture " as a unique phenomenon. On the other hand, Chinese thought comprehended the conceptual part of Spengler’s ideas taking roots in the specificity of Chinese philosophical tradition. This problem was the main focus of research. Substantiation is given to the thesis, according to which the morphology of Spengler's culture, fragmented to separate concepts and then integrated on the virtually intuitive level, can still be allotted a cultural-philosophical status in the "Chinese version". The novelty consists in reconsideration of the scientific work of Oswald Spengler through the prism of non-Western philosophical traditions, which draws particular interest in the light of development of postcolonial research.
Apophatic model of the philosophy of religion of S. L. Frank and Christian religious-mystical experience: fundamentals and results of interdisciplinary synthesis
Authors: Shugurov Mark Vladimirovich , Duplinskaya Yuliya Mikhailovna
Published: February 2022

The subject of this research is the approach of S. L. Frank towards the study of the religious-mystical experience of Christianity based on the conceptual matrix of "wise ignorance" and phenomenological method, which underlies the metaphysical system in his philosophy of religion. The authors examine in the specificity of philosophical mysticism of S. L. Frank and points of its intersection with the Christian religious-mystical experience. The unfolding of phenomenological approach to in-depth layers of the religious-mystical experience of Christianity means the functionality of philosophical reflection within the universal paradigm of Christianity, and thus, the characteristic archetype of religious-mystical experience. Special attention is given to the role of individual mystical-religious experiences of the philosopher and their rational categorization in creating his philosophical system. The main conclusions lie in theoretical provisions that Frank's philosophy of religion, outlined by him as a philosophical mystical theology, became the platform for the apophatic model of "wise ignorance", which led to theoretical reflection of the profound layers of not only mystical-philosophical, but also the religious-mystical experience of Christianity. The authors’ contribution lies in substantiation of the statement that the peculiarity of mystical-theological phenomenology of S. L. Frank is that it represents a version of contemplative mysticism and cannot be viewed as a special philosophical reflection on the diversity of Christian mysticism and the model of Christian mystical theology, which in no way detracts from the interdisciplinary nature of generalizations of the philosopher. The novelty of this article consists in explication of the philosophy of religion of S. L. Frank as a system of conceptual representations, which based on the model of apophatic "sophisticated ignorance", reflects the essential component (archetype) of the Christian religious-mystical experience underlying its diversity and divergence.
On certain philosophical-scholastic aspects of the doctrine of the Eucharist in the anonymous treatise on the Mass (manuscript München, BSB, Cgm 89)
Authors: Simonian Arina Vladimirovna
Published: February 2022

The existing representation of juxtaposition of the religious literature of the late Middle Ages and contemporary to it university philosophy requires clarification. It is particularly difficult to draw this boundary in texts of the tradition of the so-called "German mysticism". This question is discussed on the basis of the German-language work “The Mystical Treatise on the Mass and Its Effects in the Loving Soul” (Mystischer Traktat über die Messe und ihre Wirkungen in der minnenden Seele). The treatise has survived in several manuscripts of the late Middle Ages, the earliest of which is the manuscript Cgm 89 (BSB, München, near 1375). The conducted historical-philosophical analysis of the selected passages of the anonymous treatise on the Mass indicates the presence of complex combination of stylistically diverse fragments consisting of rearrangement of topoi that belong to both scholastic and religious literature of the late Middle Ages. In enunciation of the doctrine of the Eucharist, the author of the treatise resorts to metaphorical language, description of personal experience of the church sacrament. At the same time, the text identifies the references to Aristotle's treatise "On the Soul" used by the author as the philosophical foundation to describe the process of connecting the soul to God. The conclusion is made that the anonymous treatise on the Mass testifies inappropriateness of rigid juxtaposition of the traditions of religious literature and scholastic philosophy, which still can be encountered in the overall description of the Medieval intellectual culture.
Novel Modeling Approach of Carbonate Reservoirs by Integrating Geological Facies, Diagenesis, and Wireline Logs for Field Development with Insights into Low Resistivity Pay

Characterizing carbonate reservoirs is challenging due to their inherent complex nature, while diagenetic overprint causes an added layer of complexity. Diagenesis may enhance or deteriorate reservoir properties resulting in a wide range of pertinent rock types. The studied reservoirs consist of several shallowing upward cycles, which are capped by tidal flats lithofacies and evaporites, governing the spatial and temporal distribution of the reservoir units. In this work, we have used existing data to link sedimentology, stratigraphy, diagenesis, and wireline logs to build a full-field characterization model for improved well performance and prediction.

The state-of-the-art characterization workflow includes data from sedimentologic core characterization, petrographic and diagenetic analyses, routine core analysis (RCA) at multiple overburdens, mercury injection capillary pressure (MICP) measurements, and well wireline logs. The process starts with basic facies description for all cored wells, establishing the stratigraphic framework, and then characterizing the impact of the diagenetic overprint on depositional lithofacies. Using wireline logs, the altered depositional lithofacies by diagenesis are distributed within each mapped cycle of the established stratigraphic framework and then are used to generate/predict petrophysical rock types. The final detailed and obtained reservoir property information for all the facies is used in the 3D reservoir model.

This work shows and explains how facies and diagenesis led to the development of low resistivity pay positively affecting a specific reservoir. This low resistivity interval, which is not common in carbonate, is related to the presence of abundant paramagnetic minerals in the reservoir. The dispersed conductive minerals have more effect on resistivity behavior as they will induce conductivity due to their distribution and mixing with irreducible water. Variation of depositional facies has a major influence on the flow geometry. We considered these variations while generating permeability modeling as well as averaging methods, which had been used later in both static and dynamic modeling. Therefore, our petrophysical rock typing and permeability and saturation height modeling were linked to both depositional and diagenetic processes.

Establishing the lithofacies relationship to flow geometry will improve the static to dynamic match, in-fill drilling plan, as well as the well design (vertical/slanted/horizontal) for both producers and injectors.

Geophysical inversion is usually carried out to quantitatively analyze the earth model and estimate its physical properties. Successful delineation of these properties such as layer boundaries, or other near-surface structures are crucial to understand the near-surface inhomogeneity. In this study, we focus on the use of joint inversion of seismic refraction and geoelectrical resistivity datasets using local and global optimization methods. The idea is to integrate the two optimization techniques to minimize the challenges faced by each algorithm when applied alone. This hybrid algorithm (local and global) is applied on synthetic data representing simple resistivity and velocity models. About 70% of the anomalies in both seismic and DC resistivity methods were reconstructed in terms of amplitude and geometry using the local optimization algorithm, while the global optimization algorithm shows improved results as it reconstructed about 80% of the amplitude and geometry of the anomalies in both geophysical methods. The result of the synthetic application shows that the hybrid algorithm provides promising outputs in terms of resolution, geometry and amplitude of the anomalies, and computation run time.

The main exploration challenges of the Lufeng Sag, Pear River Mouth Basin (PRMB) area are complex fluvial-deltaic depositional stacking and associated oil-water distributions. The reservoir bodies are buried at approximately 2700 to 3000 m under mud lines, and at these depths the quality of the seismic data is too poor to accurately characterize the reservoirs. The poor seismic quality also results from complex fluvial sedimentation that is overlain by a high-speed limestone layer, as well as deeply buried, thin intervals of interest.

In this paper we propose an integrated approach to reprocess the data, increase the imaging quality, and improve the geological understanding of the area. The geology-guided seismic data processing and integrated interpretations, along with seismic inversions, are proved to be a practical solution to improve geologic understanding and help to conduct a drilling campaign for infill wells. The new processed data show improved image quality, including the signal-to-noise ratio and the resolution via noise attenuations, demultiples, and broadband extension processing.

Two sedimentation sources are identified with the new data, while the legacy data were vague, and the reservoir layers were interpreted as a single-sourced fluvial-deltaic depositional system. These misleading interpretations do not help us understand the complex oil-water relationship discovered by drilling and failed to locate the sweet spots for future infill wells. However, the new processed data shed light on all the issues and have become a game changer for the area.

Seismic Imaging for the small-scale feature in complex subsurface geology such as Carbonate is not easy to capture because of propagated waves affected by heterogeneous properties of objects in the subsurface. The initial step for machine learning (ML) is to provide enough data which can make our learning algorithm updated and mature. If one has not provided the multiple shapes of diffraction data, then your prediction of ML will be not accurate or even ML not able to detect the pattern of diffraction in the data. After the learning, our machine, the detection of the target is the crucial part that compares with the target and searches the specific signature in the given data. In this paper, we feed it with data in the form of the image and feature. Which can pass through the learning algorithm to predict the target. The idea of ML is to get the difference between your prediction and the target as closely as much possible. Which leads to the better preservation of diffractions amplitude in laterally varying velocity conditions. ML destruction is used for diffraction data separation as the conventional filtering techniques mix the diffraction amplitudes when there are a single or series of diffractions.
