Published: May 2022

AbstractThis study explores the life-mode of Hungarian migrants in their destination country, England, particularly London in the last decade, focusing on their housing conditions and working experiences. Relying on her participant observations and interviews, the author formulates a picture through the eyes of Hungarian migrant laborers regarding how both the real estate and labor market exploits them (micro level). She explains the motives of the main economic actors (entrepreneurs, real estate and employment agencies, employers) leading to exploitations (meso level) in addition to discussing how all of these fit into the wider socio-economic context (macro level).

Abstract
The German Seismological Broadband Array (Deutsches Seismologisches Breitband Array [DSEBRA]) comprises 100 mobile seismological stations and can be deployed as a stand-alone network or in conjunction with other stations to build an even larger array. The first mission of DSEBRA was in the framework of the European AlpArray initiative. The aim of the project is to understand the deep structure, mantle dynamics, plate tectonics, its linkage to surface processes, and seismic hazard of the Alps–Apennines–Carpathians–Dinarides orogenic system. DSEBRA, purchased in the framework of the German Priority Program Mountain Building Processes in 4D, contributed to one-third of the temporary AlpArray seismic network (AASN). The stations are currently deployed in the Alpine foreland of Germany and Austria, in the high Alps of Austria and Italy, and in the Pannonian basins of Hungary. The stations are equipped with state-of-the-art technology, thus allowing to acquire high-quality broadband data in real time. In this article, we present the current station deployment within the AASN, describing the equipment and its handling. Furthermore, we discuss the data quality and perform noise analyses. In conclusion, DSEBRA stations provide excellent data and are very well suited for deployment in national or international seismological experiments.

Miliary tuberculosis (TB) is a lethal form of TB, if left untreated. Miliary TB accounts for <2% of all cases of TB in immunocompetent individuals. Intracranial tuberculoma is a rare manifestation of Mycobacterium tuberculosis (MTB), seen in only 1% of TB patients. It can occur as single or multiple lesions, most commonly located in the frontal and parietal lobes. Clinical features mimic that of any space-occupying lesion in the brain. In pregnant women, diagnosis of TB may be delayed by the non-specific nature of early symptoms and because they are often attributed to pregnancy.Here we report one such case where the diagnosis of TB was delayed due to the non-specific nature of her symptoms in ante-natal period.

Vizsgálatunk célja az volt, hogy a középiskolákban tanító pedagógusok attitűdjét vizsgáljuk a beszédhanghibákkal rendelkező diákokkal kapcsolatban. Az áttekintett attitűdvizsgálatok azt mutatták, hogy a sztenderdtől eltérő beszédmód válthat ki negatív értékítéletet (Bodnár 2019 és Jankovics 2016). Megvizsgáltuk, hogy mutatkozik-e eltérés a beszédhanghibát mutató beszélő és a sztenderd beszélő megítélésében, illetve a jegyalapú értékelésben. Kérdőíves vizsgálatot végeztünk, a kitöltőknek 4 hangfelvételt kellett meghallgatniuk 3 beszélőtől, közülük egy személy két különböző beszédmódban olvasta fel a szöveget (sztenderd és rotacizmus). Az eredmények azt mutatták, hogy összességében kis eltéréseket láthatunk az ügynök két felvétele közötti értékelésben. Intézménytípusonként és tantárgytípusonként vizsgálva az adatokat azonban kirajzolódik, hogy a rotacizmust mutató beszélő többször rosszabb eredményeket kapott, mint a sztenderd beszélő. A szóbeli feleletek esetében a kitöltők számára általánosságban fontos szempont volt az értékelésben a lexikális tudás. A beszéd ennek fontos közvetítője, ezért annak zavara befolyásolhatja a pedagógusok értékelését.
Szerencsegyökér. Berniczky Éva novellájának retorikai elemzése
Authors: Gulyás Márk 
Published: May 2022

A Szerencsegyökér című novella Berniczky Éva fiatal kárpátaljai szerző legutolsó, összefoglaló jellegű novelláskötetének címadó darabja. Elemzése a retorika rendszerét és terminológiáját követve valósult meg. Első lépése a retorikai szituáció, azaz a megoldandó probléma vizsgálata, majd a novella típusának a megállapítása következik: a modern novellatípusok körébe illeszkedő, szimbolikus-balladisztikus novella. Ezután történik meg a novella bonyolult, párhuzamos és belső mesét is tartalmazó szerkezetének a feltárása (a belső mese is párhuzamos szerkezetű). Érvelése végig ellentétekre és ellentmondásokra épül, ezért izgalmas; az arisztotelészi enthüméma logikájával is lehet találkozni benne. Sajátos a stílusa: nincsenek benne párbeszédek, de a függő beszéd is jellemzi a szereplőket. Stílusára jellemző az allúzió és a szimbólum – maga a cím is szimbólum –, metaforái, komplex képei jellegzetesek, felfejtésük számos összefüggésre világít rá. A novella hátterében egyúttal feltárul egy szomorú, tragikus emberi sors.

Abstract
Inorganic scaling is a phenomenon of common occurrence both in nature and in industrial operations. In general, its effect can be highly detrimental for the oil industry, as fouling can take place in different stages of the production, from the well bore and downhole production control valves to upstream primary oil processing and separation equipment. The deposition of precipitated crystals on pipe walls and valves can result in severe production decline. Despite the high costs involved in the design and operation of separate lines for additive injection, chemical inhibition is typically the solution adopted by the oil companies to mitigate scaling. The purpose of the present work is to show results of a large scale laboratory pipe flow experiments to evaluate the performance of non-chemical solutions to mitigate and control calcium carbonate scaling. Magnetic, electromagnetic and ultrasound devices have been tested in a set up that simulates the mixing of two incompatible brine solutions that cause precipitation and deposition of calcium carbonate for a high Reynolds number pipe flow. The performance of the devices is evaluated from pressure drop measurements along the pipe, carbonate deposited mass on the pipe wall and reduction of pipe diameter. Additional results comprise evaluation of particle size distribution of the precipitated crystal, scanning electron microscopy, x-ray diffraction for identification of the crystalline structure and pH and conductivity. Results show that the magnetic field furnishes a beneficial effect, as it delays the time observed for the onset of flow restriction in both pipe and valve. The scaling phenomenon is shown to slow down and the delay for the increase in the measured pressure drop range between two to four times in comparison with the tests conducted without the magnetic field. Ultrasound devices are also shown to provide remarkable impact on the delay of the appearance of the scaling effects. The ultrasound field influences the precipitation phenomena so that particle sizes are kept at very small values, which prevent crystal deposition. The main contribution of the present work is to provide an evaluation method of anti-scaling devices based on large scale experiments, which are fairly representative of real field applications.

Abstract
Inorganic scales such as calcite, barite, gypsum, celestite are some of the most common scales found in oil field brines. The scale problems are generally treated with different types of inhibitors depending upon the reservoir conditions. In this paper, a newly developed BCC Continuous Stirred Tank Reactor Inhibitor screening method BCIn method will be discussed that uses Continuous Stirred Tank Reactor (CSTR) theory which has been demonstrated to work for analyzing inhibitors efficiency on the inorganic scales formed in oil/gas production. The method has been shown to be more accurate and efficient than the methods commonly used in industrial laboratories. The BCIn CSTR method varies the inhibitor concentration so that constant feeding of the same background solution maintains a constant supersaturation and volume as the inhibitor concentration exponentially decreases. The inhibitor concentration decreases exponentially to below the critical nucleation concentration (Ccrit) and thereby supersaturated brine tends to precipitate rapidly. The induction time is used to compare the efficiency of the inhibitors. The apparatus is designed so that the partial pressure of CO2, pH, temperature (T)and saturation index (SI) can be precisely controlled which makes it suitable for most of the inorganic scales including calcite, barite, CaSO4's etc. The BCIn method was used to rank 18 common inhibitors under various brine conditions, including the effect of SI, T, pH for sulfate scales and additionally ratio of Ca2+/HCO3− for calcite and was investigated by comparing the critical concentration (Ccrit). It was also found that the critical concentration (Ccrit) from CSTR method has a good correlation with the MIC from batch tests so that it can be used as fast ranking to estimate minimum inhibitor concentration (MIC) values. This study provides a simple and reliable solution for conducting scale inhibition tests in an efficient and economical manner.
Prevention of Inorganic Scale in ESPs - A Holistic Review of Scale Inhibitor Deployment Options
Authors: Johnston Clare Jennifer , Jordan Myles Martin 
Published: May 2022

Abstract
Electrical Submersible Pump (ESP) failures have a range of root causes from reservoir solids/ sand, fracture proppant and asphaltenes within the intake assembly of the pumps to deposition of different types of inorganic scale on the motor. The formation of such scale deposits is not unusual, and the mechanism of formation is well understood but the fact that scale deposition and associated pump failures can be observed to occur at water cuts of &lt;1% is less well understood. Treatments with scale inhibitor via continual injection are not always successful at such low water cuts and failure to inhibit scale can also be a result of poor understanding of the mixing point of inhibitor and brine vs the location of onset of scale formation. The deployment of conventional scale squeeze treatments can be associated with significant oil production losses which are commonly attributed to the treatment of low water cut wells with aqueous based scale inhibitors, and operational issues may be caused by the requirement to pull the pump if a bypass valve is not present.
This paper outlines the development of an effective treatment strategy for production wells that suffered significant performance impairment at water cuts below 5% due to carbonate scale deposited within the ESPs. These wells were treated with a mutual solvent and an oil soluble scale inhibitor squeeze treatment. Field results agreed with the laboratory qualification studies showing that the wells treated did not suffer any reduction in oil production rate and the ESPs were effectively protected from carbonate scale deposition.
This work was extended, and applications carried out within offshore fields in the GOM and West Africa where scale inhibitor was applied in fracture fluids programs used for frac pack operations to provide scale inhibition but eliminating the need for an initial squeeze at low water cut. The development of scale inhibitor compatible with the fracture fluids eliminated the need for expensive well intervention until the water cut of the wells exceeded 10% whereby the continual downhole injection system was able to protect the ESPs.
The paper highlights the need to understand the implication of the location of the ESP/motor within the completion in each well to allow assessment of the best scale inhibitor deployment strategy in each case. The selection of treatment strategy is discussed, along with the laboratory qualification studies required to select appropriate inhibitors. Case history data demonstrating successful deployment in the field for continual injection, solid inhibitors and squeeze application are presented, along with analysis of the risk factors to be considered when reviewing the scale formation potential over the lifecycle of a well in new field developments.
Subsurface Scale Diagnosis and Remediation to Uplift Oil Production

Abstract
Scale formation at the subsurface can block perforations, fractures, and pore throats in the near-wellbore region, causing formation damage and loss of well productivity. This paper presents a field case study with an integrated data analysis approach and conceptual model on the diagnosis, remediation, and control of subsurface scale formation.
Unlike scale deposits in production tubing or topside facility, subsurface scale deposits cannot easily be collected or visually observed due to operational uncertainty/difficulty/cost, and safety considerations. In this study, integrated data analysis and scale modeling based on field conditions and water chemistry data from downhole formation water samples, preserved core samples, completion brines, and produced water samples were utilized to diagnose subsurface scale formation and help develop remediation strategy for a deep water well with significant production underperformance (50%+ lower than expected).
MDT (modular formation dynamics tester) water data from this field can be categorized into 3 groups with higher (Type 1), medium (Type 2), and lower (Type 3) concentrations of Cl-, Ca2+, and Ba2+. A novel mathematical algorithm was developed and successfully implemented to calculate produced water source allocation and the composition of produced formation water over time. The calculated produced formation water chemistry data is consistent with MDT water database with respect to both total ion concentrations and ion-ion correlations. Produced water source allocation results show the produced formation water changed from type 1/2 water-dominating composition to type 3 water-dominating composition over time. Integration of the time-lapse produced water source allocation results, production data, and scale modeling results, and comparison with analog wells indicate potential block-out of production from certain formation zones at the underperforming well. Calcite scale precipitation at subsurface due to completion brine-formation water commingling in the near wellbore region during well completion and shut-in stages prior to production is deemed as a primary cause of the production allocation change and significant production underperformance. Learnings from this study provided an important basis to develop/optimize well remediation and subsurface scale control strategies.
This paper clearly demonstrates an integrated data analysis approach based on historical water chemistry and production profile for subsurface scale diagnosis. Moreover, a conceptual model has been developed to help explain, diagnose, and control subsurface scale formation and its impact on well production underperformance. The developed model is successfully applied and validated in explaining findings/results in this field case study.
The Future of Scale Control – The Impact of Net Zero
Authors: Heath Stephen , Mackay Eric , Bagala Stefano 
Published: May 2022

Abstract
Scale deposition in oil and gas wells is still a major issue in the oil and gas industry as it reduces hydrocarbon production, restricts well access to production logging tools and, in addition, causes safety issues due to blocking and ineffective operation of chokes and valves. Scale is predominantly controlled with chemical scale inhibitors and the most common methods to control scale deposition are through continuous injection and scale squeeze treatments although solid inhibitors can be deployed in ratholes, hydraulic fractures and gravel packs. Non-chemical methods can also be applied and are becoming more common over the last few years especially for calcium carbonate control.
Scale management is clearly still a very important factor for the good health of existing oil and gas wells and the trend towards net zero will only increase this reliance as the need for maximum production from existing assets becomes more pertinent compared to the alternative of developing new fields which will be more carbon intensive.
Existing scale management strategies will also have a CO2 footprint and scale control methods will be reviewed to become more aware of this and to highlight how certain areas of scale management can become more effective and adapt to the changing needs of the energy industry such as the increasing use of enhanced oil recovery (EOR) in both conventional and unconventional fields.
The review will include several areas of scale management including scale prediction risk, chemical and non-chemical treatments, scale inhibitor chemistry from renewable sources, monitoring techniques coupled with improved data processing techniques and automation.
The drive towards net zero has also instigated the development of alternative energy sources to fossil fuels which have resulted in a major focus on projects in geothermal energy and increased the potential for carbon capture, utilisation and storage (CCUS) projects where CO2 captured from heavy industry is transported to site and injected into geological reservoirs for storage and/or enhanced oil recovery.
Scale control will be important to both geothermal and CCUS projects and this paper will highlight examples including scale control in geothermal wells with options for treatment and desirable chemical properties and carbonate scale control in CO2Water Alternating Gas (WAG) injection whilst also demonstrating CO2 storage and enhanced oil recovery (CCUS). In addition, the potential for halite deposition and carbonate mineral dissolution and its impact on rock mechanical integrity during CO2 injection into hyper saline aquifers and depleted oil and gas reservoirs will be discussed.
