“To the glory that was Greece": Hellenic patterns in Poe's poetry
Authors: Tsokanos Dimitrios
Published: April 2018

Edgar Allan Poe’s poetry has repeatedly drawn the attention of many literary critics since his poems have meticulously been delved into from different perspectives. Undeniably, a multitude of references that allude to ancient Greek mythology and classical literature are present within his verses. These have been noticed and delineated by noteworthy Poe scholars such as Scott Peeples, Kenneth Silverman, Daniel Hoffman and Kevin Hayes in several of their researches in the past. However, despite the wide range of studies that have been published, one cannot encounter any mention regarding the existence of Hellenic motifs or even a reference to an apparent Hellenism in Poe’s poetry. In an effort to outline what has already been affirmed with respect to this topic and to unearth additional links between Poe’s works and Greece, the present essay aims to determine the presence of Hellenic motifs in Poe’s “To Helen” and “Lenore”.
Lucretius in the novel Crematorio by Rafael Chirbes
Authors: Traver Vera Ángel Jacinto
Published: April 2018

This article explores the influence of Lucretius on the novel Crematorio (2007) by the Valencian novelist Rafael Chirbes (1949-2015). Considered one of the best Spanish novelists of the 21st century, Chirbes acknowledged in several interviews the Lucretian influence on his novel and, indeed, among the funds of his library, there was a De rerum natura profusely underlined by his own hand, which will guide us in the search for concrete resonances from the Roman Epicurean. Chirbes shares Lucretius’ materialistic view of universe and uses his writings to denounce the vices of society, with a purpose of moral reform. The main motifs adapted from Lucretius are the general materialist concept of life and universe, the human being as dust, the eternal recycling of the universe’s matter and of living beings, the violence in sex, the Hell in life, and the rebuttal of wealth as a factor of evils.
A Feminist Study of Otherness in A Streetcar Named Desire and its Iranian Film Adaptation, The Stranger
Authors: Nazemi Zahra , Harehdasht Hossein Aliakbari , Movahhed Abdolmohammad
Published: April 2018

Movie adaptations of dramatic works have always been very popular. Tennessee Williams’s A Streetcar Named Desire (1947) has been adapted several times and in different ways. Feminist and gender studies have examined the important role of Otherness in the construction of female identity. Using their findings, we compare the ways in which the theme of Otherness has been employed in representing female gender identity in Tennessee Williams’s A Streetcar Named Desire and in its Iranian film adaptation, The Stranger (Bigāneh) (2014). The results of the study show that while in both works the female characters' traditional female roles have been highlighted, in the Iranian movie the main female character economically enjoys a relatively higher independence and can have a voice of her own to act against the patriarchal traditions. Besides, whereas in the source text women’s identity is solely associated with their being the Other of men, women in The Stranger stand on a par with their male companions, if not higher than them. The study also reveals that a main reason for these differences originates in the sociopolitical, cultural and historical discrepancies between the contexts in which the film and the play were created.
Automation of Tubular Running Services
Authors: Thiemann Bjoern
Published: April 2018

While automation is already a big deal for the drilling part of a well construction, tubular running services like casing and tubing installation has been more or less neglected in this process. Reasons for that are that special equipment is required for tubular makeup which is usually brought to the rig only for one particular task. Integration is often difficult since no industry standard exists for this operation. Furthermore this equipment has become difficult to use requiring special training of the operators.

The tubular running process comprises the use of a tong to makeup and break out connections. Over the years many different tong types have been developed, from manual tongs to fully mechanized power tongs. All tongs comprise a torque/turn measuring system which needs to be installed on site. Adjustments need to be made in order to reflect the setup e.g. tong type, load cell range, turns counter resolution, etc. Mechanized tongs require even more equipment to be brought to the rig floor and connected to the tong. All that leads to longer rig up time, more floor space necessary on the rig floor, more personnel and potential sources of failure. The evaluation of the connection bears another risk. So far a human looked at the torque/turns graph and evaluated the connection. This required a certain resolution of the screen and a good understanding of the connection requirements.

A new system has been developed to address the challenges described above. The new generation of tongs is equipped with computers and additional sensors. The tongs do not require any additional equipment to be connected to it. The interfaces are reduced to the minimum, using industry standards like Ethernet, Wi-Fi and Bluetooth. The makeup is now controlled by the system eliminating any operator-specific influences or other human factors and at the same time, simplifying the use of the equipment. Algorithms programmed according to pipe OEM specifications now evaluate the connection which eliminates subjective graphical interpretations.

This paper highlights the challenges of tubular running services and how this process can be automated in order to increase connection quality and reduce costs.

Published: April 2018

This case study aims to share the experience and improve the understanding of downhole shock and vibration and demonstrate how it can be prevented using thorough offset analysis, an advanced bit design, downhole mechanics module, and detailed drilling roadmap. The new approach delivered a step change in the performance of the 17 ½-in. section in Valemon field, in the Norwegian sector of the North Sea. Employing a one-run strategy through this extremely demanding section could eliminate the need for a dedicated motor run to withstand high shocks through the sandy interval with interbedded limestone and cemented sand layers. Using a point-the-bit bottomhole assembly (BHA) with a detailed drilling roadmap for every group of formations secured smooth drilling, pull out, and running of the intermediate 14-in. × 13 3/8 in. casing to provide integrity to drill 12 1/4-in. section.

An advanced bit design balanced drilling with low aggressiveness through sand without compromising the performance through the interbedded limestone stringers and claystone. The conical-shaped cutter placed behind the main PDC conventional cutters successfully controlled the depth of cut through the sandy intervals and mitigated the downhole shocks.

A detailed drilling roadmap was developed to define formation-specific drilling parameters to mitigate the shock-related failures on similar lithology.

A downhole drilling mechanics module was used to provide real-time axial, lateral, and torsional shock and vibration data, which enabled adjustment of surface drilling parameters accordingly.
Enhanced Well Control Potential with Along-String Measurements

Published: April 2018

Digitalization of the drilling process has led to an increased focus on utilizing sensor measurements topside and downhole in optimization and risk mitigation associated with well control incidents. The objective of this study is to demonstrate how hydraulic models with advanced gas loading features can aid in the automatic interpretation of ASM (Along-String Measurements) data, enhancing the well control potential in automated drilling processes.

A synthetic well control case with ASM pressure data points distributed sparsely along the string is set up. An ensemble of hydraulic model simulations with different influx parameters are run and compared with the ASM data. By considering the simulation results that best explains the measured data, a more fine-grained picture of the downhole situation is obtained, allowing for a more complete understanding of the risk of unwanted consequences. The results may be presented graphically to the drilling team, or may be accessed by control systems for automatic handling.

Based on this work, a methodology for improving automatic risk analysis in drilling operations with ASM is developed. While there has been considerable attention given to the potential of using sensor data recently, it has been less clear exactly how to get the most out of these data. The results of this study show how modeling enhances the data by providing relevant, physics-based information about gas distribution and severity along the entire wellbore. This allows for a detailed picture of the gas loading in the well, demonstrating how the combination of measurements and modelling provides an early kick warning opportunity not possible with measurements alone.

The study contributes to improved automation in the context of gas influx scenarios with ASM. This is especially relevant with regards to digitalization, which involves shifting the interpretation of sensor measurements from humans to computers. The results obtained may be an important step in achieving higher degrees of safety and efficiency in drilling automation.
Developing Gullfaks Shetland/Lista Fractured Carbonate Reservoir - From Hope and Pray to Trial and Error
Authors: Dale E. I. , Eikeberg O. , Haugen Å. , Irondelle M. , Jonoud S. , Aase S. A.
Published: April 2018

The Gullfaks Shetland Group and Lista Formation (Sh/L) are fractured chalk reservoirs located above the main Gullfaks reservoirs. Fractured carbonate reservoirs are heterogeneous, due to deposition, diagenesis and fracturing, so they are challenging to characterize and model. Shetland/Lista is considered to be a type II reservoir, according to the Nelson classification (Nelson 2001), where most of the oil is stored in the relatively high porosity low permeability (0.1 mD) matrix. The oil is mainly transported through the high permeability (several darcy) fracture system.

Production by depletion started late 2012. Historical out of zone injection that occured some time between 1994 and 2010 from the Gullfaks main reservoirs increased the reservoir pressure in Sh/L. Production from Sh/L therefore initially improved the drillability to the underlying Gullfaks main reservoirs. However, presently further reduction of the pressure is not advisable to preserve the drillability. Most of the Shetland producers are consequently shut-in. Water injection to maintain the pressure is therefore considered to be a promising new drainage strategy.

In addition to pressure support, fractured, water-wet reservoirs can benefit from water injection through increased oil recovery by spontaneous imbibition. Oil can be mobilized by spontaneous water imbibition from fracture to matrix.

Special core analysis experiments indicated water-wet conditions and potential for oil recovery by spontaneous imbibition in the Shetland reservoir. Complementary field tests were conducted to confirm this:

A single well injection and following production test (push-and-pull) with tracers, confirmed high potential for spontaneous imbibition. A multi-well pilot also showed clear indications of imbibition taking place between injector and producers, when analysing production and tracer data.

The objective of the work described in this paper is to confirm feasibility of a new drainage strategy, and confirm that pressure support by water injection will be beneficial for the oil recovery in the Shetland/Lista reservoirs through imbibition.
Drilling a Challenging Kvitebjørn Field 5¾-in. Section in a Single Run Using a New Mud Motor Modeling Engineering Workflow and New Long-Life Elastomer

Published: April 2018

The challenging environment in the Kvitebjørn field offshore Norway comprises high-temperature wells, long drilling hours, low rate of penetration (ROP), managed pressure drilling (MPD), and mud additive requirements, all of which are very detrimental for operations and reliability of the positive displacement motor (PDM) power section. In fact, until now, no one has successfully drilled the 5 ¾-in. section in a single run due primarily to motor failures such as elastomer chunking and debonding.

This paper presents the steps used for optimizing the selection of a PDM section to achieve a single-run drilling operation with improved ROP. The method includes understanding the drilling environment, type of wells, rig capabilities, formations, temperatures, MPD, and drilling fluid requirements. Furthermore, the usual motor and bottomhole assembly requirements must be evaluated and the mud compatibility with the elastomer must be scrutinized. All of these variables were then input into a modeling engineering workflow to simulate and analyze the power output, the elastomer fatigue life, the hysteresis heating, and the debonding stress to select the best possible PDM candidate for the drilling job.

A new long-life elastomer and the drilling parameters recommended by the mud motor modeling resulted in drilling this section in a single run for the first time in the field. Simultaneously, it was possible to drill to the deepest total depth without any need to set the section total depth shallower, as occurred in previous wells due to motor failures. The motor drilled through a very thick cemented sandstone stringer with no stall incidents. This motor set new records for drilling the 5 ¾-in. section with a total run length 60% longer than the previous longest run and a total pumping time 67% greater than the previous record.

The combined new technologies of the modeling and the new long-life elastomer were applied for the first time in the anticipated challenging drilling conditions. The successful results demonstrated that with thorough analysis and proper planning, one can achieve a step change in performance and reliability without additional costs. The scope of the operation is even broader than the mud motor application.
The Use of Aluminum Drill Pipe for Damping Drill String Vibrations
Authors: Brown Christian F. , Podnos Evgeny G. , Saasen Arild , Dziekonski Mitchell , Furati Mostafa Al
Published: April 2018

Drill string vibrations are a significant concern during drilling operations, and are a common cause of downhole tool failures and decreases in drilling efficiency. Drill string vibrations are typically categorized in three ways: axial (the drill string is vibrating along the axis of drilling), lateral (the drill string is vibrating perpendicular to the axis of drilling), and torsional (the rotational speed of the drill string is varying along the axis of rotation).

If applied correctly, the use of low elastic modulus and low density materials in a complex system will dampen vibrations. This hypothesis is confirmed through the use of multiple software simulations including an ABAQUS Finite Element Analysis (FEA) model and an MSC Adams multi-body dynamics model.

The simulations pointed to the conclusion that including sections of aluminum drill pipe into the drill string will dampen drill string vibrations (Dziekonski, 2017). The low elastic modulus and density of aluminum reduce both the duration and severity of torsional vibrations in a stick slip type dysfunction. The reduction in severity of uncontrolled torsional oscillations will reduce the additional strain on threaded connections throughout the bottom hole assembly and drill string, as well as the impact caused by lateral vibrations, and the amplitude of axial vibrations. This overall reduction in vibrations can be used to increase the life of sensitive downhole components and increase the efficiency of drilling operations.
Analysis of Asymmetric Tool-Joint Wear while Drilling Long Horizontal Sections
Authors: Cayeux E. , Skadsem H. J. , Carlsen L. A. , Stokland L. M. , Cruikshank S.
Published: April 2018

While drilling horizontal sections, an operator experienced tool-joint wear, which in extreme cases was one-sided, necessitating the replacement of many drill-pipes to minimize the risk of drill-string failure. Since there were no observable signs of the wearing process, the strategy has been to trip midway through the section to inspect the pipes. With the goal to drill the section in one run, an investigation of the root causes of the abnormal wear has been started.

To check whether some hidden signal patterns could help detecting under which circumstances the tool-joints were worn out, a play back of some of those drilling operations has been undertaken with specific attention to whether transient hydraulic and mechanical models could help differentiate abnormal measurement signatures. In parallel, it has been investigated with computational fluid dynamic (CFD) software whether synchronous whirl of tool-joints would generate a specific pressure signature that could easily be recognized. As the asymmetrical wear of the tool-joints indicated the presence of synchronous whirl, it has also been analyzed how side forces were distributed along the drill-string.

Neither the playback nor the CFD analyses pointed to conditions leading to tool-joint wear. On the other hand, the side force analysis showed that because of extensive directional work linked to geosteering, reaction forces on the tool-joints were very unevenly distributed on the first 500m of drill-string behind the BHA. However, the distribution of the positions of the high and low side forces changed radically for different bit positions. Numerous hard-stringers were encountered while drilling which suggests that the irregular distributions of side-forces on the string have been maintained for longer periods of time. As a result, these conditions have allowed drill-string whirl to be kept sufficiently steady with the consequence of severely damaging the tool-joints.

Mathematical modelling of the drill-string behavior can help determining the critical rotational speed as a function of the weight on bit by which whirl can take place. With this information at hand, it is then possible to give concrete advice to the drilling team on which drilling parameters to use to minimize the risk of tool-joint wear.
Installation of the Longest High-Performance and Rotating 11-3/4" Solid Expandable Liner on a HPHT Infill Well with Narrow Mud Weight Window
Authors: Alahmad Mohammad , Wang Bruno , Baker Roy , Booth Graeme
Published: April 2018

This paper discusses installation of the longest high-performance (HP) and rotating 11-3/4" expandable liner on the Elgin field in the Central-North Sea sector of the UK that enabled isolating weak layers in the overburden formations on EIE well, providing sufficient mud weight window to permit drilling high pressure and gas bearing zones. The planning and execution of this record presented challenges beyond those encountered in standard well conditions due to narrow mud weight window (NMWW) and critical requirement of zonal isolation.

EIE well was the third of the 2015-2017 infill campaign on Elgin field. The well faced major challenges in the 12-1/2" section due to the NMWW which triggered the deployment of the contingent well architecture with HP 11-3/4" expandable liner. This critical requirement of zonal isolation significantly impacted the preparation and risk assessment of expandable liner operations. A new expansion assembly design was implemented to allow rotation of the 11-3/4" size system to improve the cement job quality. Moreover, all contingency procedures were significantly modified to ensure that the objective of the specific well constraints were considered.

After under-reaming while drilling 12-1/4" × 14" section down to planned depth, 860m of 11-3/4" liner was run with no open hole problems. This liner was successfully rotated at bottom prior to pumping cement and fully expanded without incident. The system was successfully pressure tested prior to drill-out of the plugs and the shoe assembly was drilled with no issues.

Running of an 860m HP 11-3/4" expandable liner and rotating shoe assembly on EIE well is a record (longest HP string run before was 360m) and considered as a remarkable achievement. However, liner objectives were not fully met and cement squeeze below the shoe had to be performed. Post-job investigation highlighted issues related to dart selection and related cement over-displacement, limited contingences in case of expansion pressure loss, and the ability to pull the liner to surface in a NMWW. These issues remain to be solved for optimisation of future deployments.

This paper provides information on the design and operational aspects that should be considered for expandable liner operations on complex wells with NMWW. Understanding advantages and limitations of the system will open up opportunities to improve the technology and help to reduce operational risk.

Authors: Santos Gleyson Moura dos
Published: April 2018

A Leishmaniose Tegumentar Americana (LTA) é uma doença causada por protozoários do gênero Leishmania e é transmitida ao homem pela picada do mosquito flebotomíneo. A LTA representa um grande problema de Saúde Pública, pois além da alta incidência e ampla distribuição geográfica, é uma das afecções dermatológicas que merece mais atenção devido à sua magnitude. Este estudo teve como objetivo descrever o perfil epidemiológico e clínico da LTA bem como sua distribuição espacial no estado do Maranhão no período compreendido entre os anos de 2012 a 2015. Trata-se de um estudo descritivo/retrospectivo de base populacional, utilizando dados secundários de casos confirmados LTA registrados no Sistema de Informações de Agravos de Notificação (SINAN) e disponibilizados no site do Departamento de Informática do Sistema Único de Saúde (DATASUS). Foram registrados 8.625 casos, com incidência média de 31,68 casos/100.000 habitantes. A baixa escolaridade foi um fator relevante. A LTA foi mais prevalente em indivíduos do sexo masculino, na faixa etária de 20 a 59 anos, de cor parda e residentes em zona rural. A forma clínica mais prevalente foi a cutânea, sendo em sua maioria diagnosticada por exames laboratoriais. A taxa de letalidade da LTA foi baixa e a maioria dos casos evoluiu para a cura. Conclui-se que é necessária a mobilização constante de recursos para que os planos e ações de controle propostas pelo Ministério da Saúde tornem-se eficazes, e também que profissionais de saúde sejam capacitados para atuarem nos serviços rotineiramente. Descritores: Perfil de Saúde; Leishmaniose Cutânea; Epidemiologia; Saúde Pública.

It is recommended the temporary immobilization of TMJ for pain relief and remission of the inflammatory process that affects the ligaments and articular capsule. This containment is traditionally made with cotton bands but difficult to find if this type of material in a dental office. We present a simple method of mandibular immobilization using disposable surgical mask. We believe it’s as effective as the traditional bandage, easily and quickly applied, cheaper and made with material that is readily available in dental offices. We are using this device for more than 15 years with excellent results and we recommend the use.Descriptors: Temporomandibular Joint; Fracture Fixation; Immobilization.

We evaluated the presence of microorganisms in spring waters (SW) and bottled mineral waters (BMW) samples. Routine microbiological indicators, additional microorganisms like Legionella spp., Nontuberculous mycobacteria (NTM) and amoebae (FLA) were assessed in 24 SW and 10 BMW samples performing cultural and molecular methods. In 33 out of 34 samples, no cultivable bacteria ≥10 CFU/L was found. Cultivable FLA were detected in 50% of water samples. qPCR showed the presence of Legionella qPCR units in 24% of samples (from 1.1 × 102 to 5.8 × 102 qPCR units/L) and NTM qPCR units in 18% of samples (from 1 × 102 to 1 × 105 qPCR units/L). Vermamoeba vermiformis and Acanthamoeba polyphaga were recovered respectively in 70% of BMW samples (counts from 1.3 × 103 to 1.2 × 105 qPCR units/L) and 42% of SW samples (from 1.1 × 103 to 1.3 × 104 qPCR units/L). Vahlkampfia spp. was detected in 42% of SW and 70% of BMW samples (from 1.2 × 103 to 1.2 × 105 qPCR units/L). Considering the presence of FLA, we underline the importance of a wider microbiological risk assessment in natural mineral waters despite the absence of cultivable bacteria.

On-site odor measurements and mathematical modeling are useful for identifying the odor impact at the source and receptors located in areas adjacent to wastewater treatment plants (WWTPs). Impact of open area sources can be significant and may influence air quality both at the WWTP area and downwind in the surrounding areas. In this work, results of the odor measurements carried out in the spring and summer season for sources within three different mechanical-biological WWTPs in Poland are presented. The odor impact assessment was completed using a Polish reference model. The odor emission scenarios considering the contribution of major odor sources within WWTPs and the seasonal variation were determined. Obtained results showed significant differences between spring and summer seasons. The highest and the lowest measured odor concentrations at the WWTP property line were 75 ouE/m3 (July) and 6.4 ouE/m3 (March), respectively.
A comparison of alum sludge with peat for aqueous glyphosate removal for maximizing their value for practical use

This study compares and contrasts the glyphosate removal efficiency of alum sludge (waterworks residue) and Irish peat in aqueous solution. Organic phosphonate of glyphosate aqueous solution was removed in pot tests separately filled with peat and alum sludge, while effluent samples were taken from each pot to analyse the concentration of phosphorus (P) and COD (chemical oxygen demand); physical and chemical analysis for both media before and after use was carried out subsequently. The results show that the P removal capacity of alum sludge was significant (>99%), while the removal capacity of peat was considerably less than 10% after 10 weeks. Both materials significantly reduced the levels of COD, but it was noted that peat had a marginally greater initial P removal capacity (68 ± 22%) and did perform better than alum sludge (57 ± 12%). Moreover, pre-treatment is a crucial step to harness the full potential of peat. Overall, this study provides a scientific clue for sorbents selection when considering alum sludge and peat to maximize their value in practice.
