„…Úgy érzem, mintha kiesnék ebből a világból.” A lélektani krízis átmeneti tapasztalatának narratív sajátosságai
Authors: B. Erdős Márta 
Published: June 2018

Háttér: A lélektani krízis során a személyes identitást szervező központi jelentések alkalmassága, stabilitása megkérdőjeleződik. A korábbi szerveződések felbomlása új koherencia kialakulásával jár. Az újjászerveződés folyamatainak pontosabb megértéséhez olyan elméletek lehetnek segítségünkre, mint az identitás strukturális analízise (Weinreich, 2003), a batesoni (1972) másodfokú változás gondolatköre, vagy a „második esély”, a „második születés” konstrukciói alapjául szolgáló átmeneti rítusok elmélete. A krízisállapothoz kapcsolódó autobiografi kus szövegek értelmezésének főbb kérdéseit elsősorban a diszkurzív pszichológia (Harré, 1998; 2004, Kézdi, 2003) és Hanninen (2004) narratív cirkulációs modelljének elméleti keretei között tárgyaljuk.
Célok: A lélektani krízis állapotában keletkező, a mélyreható változásokat megmutató, egyben érvényre juttató önreflektív szövegek, élettörténeti epizódok vizsgálata, különös tekintettel az átmenet sürgős beavatkozási pontot jelentő liminális fázisára.
Módszer: Cry for help beszélgetés kvalitatív tartalomelemzése.
Eredmények: Az eredmények rávilágítanak a narratív identitás felbomlásának és újjászerveződésének folyamataira, a megélt (élményszintű), a belső és az elbeszélt, a személyességen túl a kulturális konvenciókat is megjelenítő narratíva kapcsolódási pontjaira, és e folyamatok nyelvi leképeződésére.
Konklúzió: Krízisben az élettörténeti forgatókönyv, az események elrendezése, a kulcsfontosságú jelentések gyökeres változáson mennek keresztül. A személy tudatában van létezése folytonosságának, önmagával való azonosságának, mégis gyakran újjászületésként, második esélyként tekint a sorsfordító krízisek nyomán megélt ugrásszerű változásra. A változás középső, liminális szakasza egyes sajátosságainak ismerete – így a paradoxonok és az ambivalencia, az elveszni látszó kontroll nyelvi jegyei, a sajátos időviszonyok leképezése, a forgatókönyveket szervező és magukba sűrítő konceptuális metaforák, mint pl. a zuhanás-kapaszkodás – a segítő beavatkozások során fontos tájékozódási pontokként szolgálnak a gyakorló szakember számára.

Published: June 2018

Some fish groups are common on coral reefs, but we still lack fundamental information about how fish assemblages vary across seascapes. The order Tetraodontiformes, which includes pufferfish, triggerfish, shingles, porcupinefish, burrfish, leatherjacketfish, filefish, and trunkfish, is one such group. We systematically surveyed 75 sites around 52 islands of the Andaman and Nicobar archipelago to evaluate the occurrence and distribution of tetraodontiform fishes. We recorded 25 species from 16 genera and 6 families. We found the distribution of fishes to vary between sites and geographical regions, with the southern Nicobar region having higher species richness than other geographical regions in the island group. Possible reasons for the observed patterns of the occurrence and distribution of tetraodontiform fishes are discussed.

Purpose. To assess the effectiveness of various techniques of surgery of pulmonary metastases based on the outcomes of surgery interventions, frequency of postoperative complications and overall survival of patients.Patients and methods. Ninety-seven patients with suspected lung metastases of known primary malignancies (47 men and 50 women, mean age of 46,5 years) were retrospectively included in two study groups between 1 January 2004 and 1 January 2016 and underwent pulmonary surgery with the Nd: YAG laser of the 1318 nm wavelength (Group A, n = 44) or with the electrocautery (Group B, n = 53).Results. A total of 151 operations were performed: 75 in Group A, 76 in Group B. The mean number of resected pul­monary lesions was 8,2 (95% CI: 5,2–11,1) in group A and 4,9 (95% CI: 3,7–6,0, p = 0,047) in group B. Additionally 87 lesions were evaporated due to small sizes (1–2 mm) in Group A. The mean time of surgery was 146 minutes in Group A and 113 minutes in Group B (p < 0,01).Post-surgery complications were diagnosed after 9 and 19 of interventions in Groups A and B, respectively. The most common complications were pneumonia, pneumothorax and subcutaneous emphysema. The number of Grade III com­plications according to Clavien-Dindo classification was 2 and3 inGroups A and B, respectively. The survival rates were computed for all patients: the one-year, three-year and five-year survival rates were 83,7%, 49,7% and 36,7%, respec­tively.Conclusion. The Nd:YAG laser with wavelength of 1318 nm allow extensive parenchymal resections without an increase in post-surgery complications and may have advantages in pulmonary metastasectomy, especially in patients with mul­tiple pulmonary lesions.

Abstract
In the Gulf of Mexico, an important number of wells in carbonate reservoirs produce heavy oil through electric submersible pumps (ESP). The efficiency and useful life of pumps decrease due to the formation of mineral scales inside the pumps. Study of the main scale components and their origin led to look for a scale remover that is optimal for removal and that has no detrimental effect on the ESP components. Additionally, changes in the operational procedure were implemented to decrease scale formation occurrence.
Inorganic scale samples were recovered from an ESP and characterized by X-ray analysis. The scale modeling software in conjunction with water analysis provided key information to predict the scale tendency and mineral composition under reservoir and operational conditions. These analyses identified the formation of two main scale minerals: calcium carbonate (CaCO3) and calcium sulfate (CaSO4). The origin of these minerals is driven by the incompatibility of formation water with water-based drilling fluids, auto-scaling due to temperature changes occurring into the ESP equipment, and the produced water flowing through the pump.
Laboratory experiments were focused on finding the appropriate scale remover that could dissolve the inorganic samples that were recovered from the ESP equipment. The screening of several products allowed identifying the chelating agent with the highest activity dissolving calcium carbonate and calcium and barium sulfate scales in a single treatment.
Corrosion and sensitivity tests were carried out for the metallic and nonmetallic ESP components. These results showed that the product does not have significative effect on the different parts of the ESP equipment; compatibility tests with the heavy oil and the chelant product were also satisfactory. Because of these encouraging results, a field validation test was implemented with outstanding results—the oil well production increased significantly and the temperature in the ESP equipment was improved.
The implementation of this chelating agent in wells presenting scale formation significantly improved the oil production and increased the ESP run life cycle under profitable economic indicators. The operator has implemented an operational procedure for wells operating with ESP that consists in continuous monitoring to optimize the treatments.

Abstract
Deposition of inorganic scale on downhole completion equipment contributes to significant downtime and loss of production within the oil and gas industry. High temperature/high pressure (HT/HP) fields have reported build-up of lead sulfide (PbS) scale as a consequence of reservoir souring. This paper reports on the design of an experimental rig allowing diffusion of H2S into a scaling brine under dynamic environments. Multiphase conditions induced by introduction of a light distillate within the system were used to create an emulsion in order to reflect more accurately the scaling process occurring within sour systems. The results showed that the presence of an oil phase within the system caused the lead sulfide nano crystals to reside at the oil- water (o/w) interface; increasing surface build-up propensity through an adhesion process. Performance of a range of coatings for potential application in oilfield environments was determined through gravimetric measurements and microscopy techniques and the wettability of surfaces was shown to have a significant influence on the degree of lead sulfide deposition in a multiphase system.
The Procedures that Time Forgot: Sample Preservation, Back to Basics
Authors: Johnston C. J. , Jordan M. M. 
Published: June 2018

Abstract
A key part of the oilfield scale management toolbox is the ability to determine the concentration of residual scale inhibitors and scaling ions in produced waters. This data is essential to providing correct recommendations for how to manage and inhibit scale in a particular system, as well as monitoring the efficacy of scale management processes already in place.
The progression of analytical techniques over the last two decades has provided enhanced methods for accurate detection of ions and scale inhibitors to low limits of detection, however, correct detection of analytes present in a sample in the laboratory does not necessarily equal characterisation of the analytes in-system as they were present at the point of sampling.
The collation of a range of preservation techniques, each appropriate to a different group of analytes, forms the basis of this paper. The results of several field applications of incorrect sample preservation are outlined and the alternative preservation technique used to correct the analysis will be detailed.
The implication of using the correct preservation technique will be clearly shown to have an impact on scale management where it would lead to reduction of over treatment, leading to increased revenue, whilst also eliminating incorrectly scheduled early well interventions.
Correcting for Mud Filtrate Contamination of Formation Water Samples for Scale Management Planning: A Case Study from the Nova Field, Norwegian North Sea
Authors: McCartney R. A. , Hatscher S. T. , Droppert V. S. 
Published: June 2018

Abstract
To develop scale management strategies and plans during field development planning, it is important to know the composition of formation water in the reservoir. Typically, formation water samples will be collected from appraisal wells and analysed for this purpose. However, when the wells are drilled with water-based mud, the samples are often contaminated with mud filtrate that has invaded the formation during drilling. By adding a tracer to the drilling mud and using a simple mass balance correction technique, it is possible to correct for the effects of contamination and obtain an estimate of the formation water composition. But, where reactions occur during invasion or within the sample after collection, this method of correction will generate an erroneous estimate of the composition. The errors will increase with the extent of reaction and degree of contamination.
In this paper, we describe a new ‘correction’ approach which additionally makes use of (a) 1-D reactive transport modelling of mud filtrate invasion and (b) modelling of reactions occurring in formation water samples after collection. This approach accounts for the potential effects of these reactions and provides an estimate of the formation water composition within uncertainty limits. It reduces the risk of obtaining erroneous estimates of formation water composition and is particularly beneficial where reactions occur and where the mud contamination fractions are elevated (e.g. ~10-40%). At higher fractions, the uncertainties can be so high that the estimated compositions are not useful, emphasising the risks of trying to estimate formation water compositions from heavily contaminated samples.
This approach has been applied to formation water samples obtained from the Nova Field (formerly Skarfjell, Norwegian North Sea). It has meant that the resulting composition and associated uncertainties have been used with more confidence in scale management planning; to select seawater as the injection water, and to identify the scale risks across the relevant nodes in the production process over the life of field of the asset. Based on these risks, appropriate scale mitigation and monitoring measures have been selected.
Mechanisms and Mitigation Strategies of Iron Sulfide Deposition in Sour Gas Wells
Authors: Chen Tao , Wang Qiwei , Chang Frank 
Published: June 2018

Abstract
Iron sulfide deposition on downhole tubular is a ubiquitous phenomenon in sour gas wells, especially for these producing from high temperature and high pressure (HTHP) reservoirs. Many studies have been focused on iron sulfide formation and mitigation previously, the root-cause of iron sulfide deposition is still not well defined and the cost-effective scale management strategy is remained to be identified.
This paper presents some new progresses made for understanding the mechanisms of iron sulfide deposition in the sour gas wells, using a combined approach of laboratorial tests and model prediction.
Study results indicate that iron sulfide can deposit during both acidizing treatment and production stage. Large amount of iron sulfide could precipitate during acidizing treatment and potentially causes severe formation damage. During production stage iron sulfide is accumulated on tubular surface due to corrosion of the underlying metal.
This paper presents a fundamental study to understand the mechanisms of iron sulfide deposition in sour gas wells. Corrosion and scaling inhibition are recommended to mitigate iron sulfide deposition in sour gas wells, especially during acidizing treatment.

Published: June 2018

Abstract
The pipelines and vast infrastructure required for the production and transport of oil and gas are largely constructed of carbon steel. This material is highly susceptible to damage and failure as a result of direct or indirect Microbially Influenced Corrosion (MIC). One approach to reduce and/or remediate MIC is the application of microbicides to affected assets such as storage tanks, pipelines, heat exchangers and pumps. The objective of this paper is to generate efficacy data for biocidal formulations against corrosion-associated biofilms grown under anoxic and flowing conditions, which is difficult to obtain due to the distinct nature of biofilms and growth conditions. This data can be more representative when mimicking petroleum and water transporting pipelines. Thus, to facilitate the testing and comparison of products that successfully attenuate MIC under field-relevant conditions, a method that allows consistent corrosion measurements to be made, for corroding biofilms grown on steel surfaces under flowing and anoxic conditions, has been developed. This method utilizes microorganisms that were enriched on carbon steel from a North Sea sediment sample that, when grown in recirculating flow circuits, can generate corrosion rates of up to 65 mpy after four weeks of growth. The samples taken for the enrichment of corroding cultures came from a low tide anoxic sediment sample (black sand). In this presentation and paper, this method and its application to the benchmarking of field-relevant biocidal chemistries in MIC control experiments are described. Attention will be given to the reproducibility of the method as well. Distinct differences can be observed in biocidal performance against biofilms developed on metal surfaces.
