Authors: Widayati Nur
Published: April 2018

ABSTRACTDental caries is one of the dental health problems. Dental caries are formed because there was leftover food that sticks to the teeth, which eventually lead to tooth calcification. Impact, teeth become brittle, hollow, even broken.Dental caries experience a loss of power to make a child chewing and digestive disruption, which resulted in growth of less than the maximum. This study aims to determine the relationship of parents’ behavior towards the maintenance of dental health of children (feeding habits sweet, sticky and drinking milk, teeth maintenance, inspection tooth and mouth) with dental caries in the TK R.A Bustanussholihin in Balun village Turi District of Lamongan. This study Analytics whose data is collected with a cross sectional sample of kindergarten children aged 4–6 years with a total sample of 49 children. The collection of primary data through interviews parents TK R.A Bustanussholihin student using questionnaires and secondary data obtained from the agency are in the region of the profile data TK R.A Bustanussholihin in Balun Village of Turi District of Lamongan. This study used a correlation coefficient of contingency. Based on the results of the contingency coefficient correlation test showed that the factors that have a strong relationship is the habit of feeding the sweet, sticky, and drink milk with a value of P = 0.504. While the factors that have a weak link is the habit of maintaining dental hygiene habits of children and child oral examination . From this study it can be concluded that there is a relationship or a strong correlation between feeding habits sweet, sticky and drinking milk with the incidence of dental caries in children aged 4–6. So as to prevent dental caries severity we need to hold counseling on feeding sweet, soft and gooey on the effect of dental caries as well as how it should be formula feeding or breast milk to the child to prevent rampant caries.Keywords: dental caries, sweetened food, children aged 4–6 years

Predisposing, Enabling and Reinforcing Factors of the Utilization of VCT by Men Who Have Sex with Men (MSM)
Authors: Fatmala Risanita Diah
Published: April 2018

MSM have a higher risk of HIV infection due to their multiple sexual partner behaviour and the anal intercourse practices. The incidence of HIV and AIDS by MSM is increasing compared to the years before. VCT is one of the effective strategies of HIV and AIDS prevention and treatment. Whereas the access to VCT services by MSM is still considered as low by the reason of the stigma and stereotypes against MSM and HIV and AIDS itself. The study is intended to explore the factors related to the MSM willingness to conduct VCT. This study used a qualitative method. We identified 9 key informants through snowball sampling method at IGAMA Malang. Data was collected by in-depth interview, analyzing descriptively, and presenting in a narrative. The results show that most of the informants has an adequate of knowledge concerning the VCT, HIV and AIDS. However, access to VCT services is still constrained by the schedule since most of the services are in the work days. The impetus for accessing VCT derived largely from community friends. With respect to the societal stigma and discrimination towards homosexuals, we did not recognize personal stigmatizing attitude and discriminatory behaviors by health workers. It makes them feel convenient because they are familiar to the health workers. The conclusion was that factors associated with the utilization of VCT service by MSM includes knowledge, perception, information, availability of the services, peer supports, and the attitudes or behavior of health workers. We suggested that VCT services would be better if could be performed also in the weekends.Keywords: HIV and AIDS, Men Who Have Sex with Men (MSM), VCT utilization

The significance, for readers in the twenty-first century, of the character of Safie in Mary Shelley's Frankenstein
Authors: Mbithi Esther K.
Published: April 2018

This paper presents a critical look at one of the characters in Mary Shelley’s Frankenstein, Safie, through the lenses of a female African scholar in the twenty-first century. A close look at the narrative structure leads to the gradual peeling off of the first two layers, to the core of the narration. The paper looks keenly at a minor character in this core, in the light of feminist literary criticism and against the concept of globalisation. The analysis of the character of Safie, carried out in full consciousness of the fact that Frankenstein was written two hundred years ago, involves a look at the words used to describe her; comparison between her and other characters, particularly other female characters; as well as a general overview of her circumstances and how she reacts in response to them.

An Improved Correlation Approach to Predict Viscosity of Crude Oil Systems on the NCS
Authors: Møller Jørgen Bergsagel , Meisingset Knut Kristian , Arief Ibnu Hafidz
Published: April 2018

An accurate estimation of viscosity values is imperative for an optimal production and transport design of hydrocarbon fluids. Based on this requirement, precise and robust empirical correlation models are highly requested. Even though there are numerous correlation models from literature, most models are inadequate to predict an accurate oil viscosity using unbiased data. This study aims to develop new and improved empirical viscosity correlations through available field measurements on the NCS. The performance of the proposed models is then studied through a comparative analysis with published correlations from literature.

New correlation models are developed for dead, gas saturated and undersaturated oils using Particle Swarm Optimization (PSO) and Radial Basis Function Network (RBFN). The first technique is a computational optimization algorithm that aims to improve a function with respect to a specified objective function, while the latter is an artificial neural network model that utilizes radial basis functions as activation functions.

The optimization algorithm is used to re-calculate the coefficients of established viscosity correlation expressions while maintaining their functional form. The results show that the modified correlation models are more in agreement with the test data for all three oil types using the defined parameters from literature, compared to the established empirical correlations and the RBFN. The new correlations provide a mean absolute percentage error of 15.08% and 17.41% and 3.35%, for dead, saturated and undersaturated oil viscosity, respectively. The highly accurate result in the latter correlation is linked to the input variables, as the undersaturated viscosity is a function of saturated viscosity, which is presumed known.

The results of this study make it reasonable to conclude that the proposed correlation methods are more in-line with the measured viscosity on the NCS compared to the discussed correlation models from literature.
An Experimental Facility for Evaluating Well Barrier Verification Technology
Authors: Gardner D. J. , Pirovolou D.
Published: April 2018

When designing a plug and abandonment (P&A) operation the barrier quality of the casing cement sheath must be assessed such that an optimal P&A solution can be chosen in terms of technical quality and operational cost. Borehole cement evaluation logs are often used for this purpose.

A full-scale facility is being built whereby commercial tools and emerging barrier evaluation technologies can be evaluated. The objective is to provide reference conditions for cement barrier verification experiments. A particular aim of the project is to support the development of technologies for logging through multiple tubulars.

Barrier reference test cells have been constructed representing a range of annular leakage scenarios such as gas channels, mud channels and de-bonded cement. The test cells can be coupled together using quick unions and extensions are available to account for the different logging technologies. The casing and annulus can be pressurized with different fluids and controlled leakage rates can be applied with water and gas.

Experiments performed to date encompass commercial logs, alternative barrier verification technology and an X-ray concept for logging through multiple tubulars. The facility design and operation and experiments executed are described.
Askeladd Field Development: The Unknown Fairytale Going on in the Barents Sea
Authors: Vinje Jo , Shoaei Farokh
Published: April 2018

The Askeladd field was the first discovery of hydrocarbons in the Barents Sea. The discovery wells were drilled in the early 1980, yet the field remains to be developed. The field is part of the Snøhvit Unit that consists of the three main fields: Snøhvit, Albatross and Askeladd (see Figure 1). Snøhvit was set in production in 2007 and Albatross in 2010. Both fields are providing feed gas to the Hammerfest LNG plant (HLNG).

The feed gas to the HLNG plant will start to decline in in not too many years’ time. In the business planning phase two measures to mitigate the decline was looked at: i) install an onshore compressor at HLNG, or, ii) start gas production from the Askeladd field. The startup of compression before all major resources is set in production violates the standard way of setting up a drainage strategy. However, for making decisions it is creating value that matters. The full life time production profile for HLNG did not show any significant difference between the two concepts. Since the onshore compression solution is slightly less costly than the development of Askeladd, that case was for a long time the strongest. It was not before the full profile was broken into single investment steps that the project showed that Askeladd was more economical. This process also brought to light why compression should not start prior to all major fields being set in production.

Further maturation of the Askeladd project focused on maximizing production by drilling horizontal wells, and minimizing pressure drop in pipelines, subsea production system and wells. The risk of water production is mitigated by multiphase meters on each well, and the ability to shut off water producing zones in the wells (identified by tracers).
Innovative Approaches for Full Subsea P&A Create New Opportunities and Cost Benefits
Authors: Øia Thomas Monge , Aarlott Mats M. , Vrålstad Torbjørn
Published: April 2018

Plug and abandonment (P&A) of subsea wells is very costly and usually requires semi-submersible drilling rigs (SSR). To reduce total costs of the subsea P&A campaigns, it is beneficial to perform P&A operations with riserless light well intervention (RLWI) vessels instead of rigs. Currently, a drilling rig is required for performing P&A operations in the reservoir section and overburden, whereas intervention vessels can be used for preparatory work and wellhead removal.

This paper discusses how it can be technologically feasible to perform full P&A of subsea wells with RLWI vessels. It is shown that, for wells of simple and medium complexity, innovate approaches with use of existing technologies can enable full P&A of the entire well with RLWI vessels. This is demonstrated by thorough analyses of operational procedures using available technologies, where RLWI operations are compared to rig operations for different well scenarios. Furthermore, to quantify the cost benefits of the innovative approaches, a cost-optimization tool has been used to estimate the resulting cost and time durations of the different approaches and scenarios.

We show experimentally that surface treated silica nanoparticles greatly enhance the thermodynamic stability of CO2-foam compared to other foam stabilizers at elevated temperatures and salinities in the presence of oil. The aqueous nanofluid mixes with CO2 in the porous media to generate CO2-foam for enhanced oil recovery by improved sweep efficiency, resulting in reduced carbon footprint from oil production. Our results show that surface modified nanoparticles are able to stabilize CO2-foam at elevated temperatures and extreme brine salinities, and demonstrate that nanoparticle injection for improved CO2-foam mobility is an upcoming CCUS technology for mature fields. New experimental results show that 1) nanofluids remain stable at extreme salinities (up to 25 wt% TDS) with the presence of both monovalent and divalent ions; 2) both pressure gradient and incremental oil recovery during tertiary CO2-foam injections were 2 - 4 times higher with nanoparticles compared to no foaming agent; 3) CO2 stored during CCUS with nanoparticle stabilized CO2-foam increased by over 300% compared to co-injections without nanoparticles.
Innovative Test Solutions of Drilling & Completion Fluids to Maximize Well Productivity
Authors: Ibragimova Zalpato , Mathisen Anne Mette , Fleming Niall
Published: April 2018

From a production or injection point of view, the two most important parameters for drilling and completion fluid are effective clean-up upon well start-up and compatibility with the selected lower completion solution to avoid impairment to well productivity or injectivity.

This paper presents results from laboratory tests using Statoil's innovative test methodology for verification of drilling and completion fluids to avoid completion incompatibility and maximize well productivity.

API/ISO standards specify a set of tests for characterization and selection of drilling and completion fluids. However, in spite of fluids showing similar results under such testing considerable disparities can be observed when the same fluids are used in the field.

The aim of the paper is to provide a thorough comparison of different reservoir drill-in and screen running fluids that have been examined using Statoil's internal non-standard methodology. It is demonstrated how fluid design, and chemistry in combination with solids, may be used to interpret results with respect to risk of productivity impairment.
Sleipner B-1 Straddle Operation and Crossflow Project
Authors: Vevatne Jonas Nesland
Published: April 2018

Sleipner Vest is a large gas-condensate field which is produced by pressure depletion. Currently (January 2018) the best production well is B-1. B-1 is placed in a segment with very strong pressure support from aquifer. In summer 2016, it was about to water out. A straddle operation was planned and executed.

The straddle operation was very successful. More than a year later, B-1 still produced more than twice as much as any other Sleipner well. However, the water is eventually expected to come back in the remaining perforations.

Production at Heidrun is normally limited by the gas handling capacity. Maximum oil production is achieved by producing wells with the lowest gas/oil ratio (GOR) and at the same time utilize the available gas capacity. GOR may change over time, so to obtain desired production it is vital with a continuous follow-up work of well testing and maintenance of multiphase meters. The Heidrun field also has many wells with challenges like; sand entrainment, drifting draw-down, limited draw-down or bottom hole pressure (BHP) and drifting GOR. These elements are crucial to control to achieve desired production. This time-consuming task is handled through a close cooperation between offshore operations and production engineers onshore. Automatic choke control is installed at Heidrun to ensure operation at the maximum gas capacity and keeping the wells at desired operating point. The automatic controllers lead more precise production from each well with a totalized higher production, reduced emissions, reduced operator loads and is a valuable tool for production optimization.

An oil field can be classified as mature when its production rate is significantly declining and/or when it is close to reaching its economic limit. A field might also be considered mature when it is close to attaining a recovery factor considered acceptable for its reservoir mechanisms. Strategies and methodologies to rejuvenate the field, enhancing production and increasing longevity of life will then commence. One of the most common methods of enhancing oil recovery (EOR) is by means of waterflooding, a device whereby injector wells are drilled in an oil field to inject water or gas into the reservoir to increase pressure and stimulate production. This, however, is a complex process posing its own uncertainty in optimally delivering increased production due to the complexity of reservoir type and well design. Having the ability to listen behind casing and deducing flow allocation of injection in which to increase the sweep and improving reservoir production performance becomes vital to enhancing oil recovery.

This paper demonstrates how spectral noise logging has aided in rejuvenating oil fields and enhancing oil recovery. Three different oil field examples are examined and discussed, illustrating the methodology and benefits of better understanding flow allocation behind casing to provide much-needed solutions to aid in field life longevity.
MWD Wellbore Surveying – Sensitivity Analysis of Survey Errors as a Function of Hole Inclination and Compass Direction

Published: April 2018

Measurement While Drilling (MWD) is a common survey tool used in wellbore positioning. The industry often uses the Industry Steering Committee on Wellbore Survey Accuracy (ISCWSA) error models for estimating the Wellbore Position Uncertainty (WPU). However, the model's sensitivity to direction and nature of trajectory has not been discussed in detail. In this paper, a software model has been developed to better understand the influence of the individual error sources on measurement and position uncertainty in various drilling directions and hole sections.

Most operators have classified accurate wellbore positioning and directional design as one of the pillars of safety. It is commonly known that measurement accuracy of frequently used MWD instruments decreases with increasing hole inclination. Survey accuracy is also influenced by North to East direction. This work provides a detailed understanding of the behavior and contribution of each survey error source and screens the error terms contributing most towards WPU. Visualizing the contribution of each error source as a function of well path direction and inclination will support the understanding of position uncertainty of individual wells.

The results in this paper are based on analysis of the ISCWSA Non-mag error model. It has been observed that some errors are most dominant in the North/South drilling direction while others are most dominant in the East/West direction. Similarly, some error sources are most effective in the vertical hole section and least effective in the build-up or horizontal sections. This process continues for all different error sources in various hole sections and drilling directions. Therefore, this paper has summarized the most important error sources for the vertical, build-up and horizontal sections of the three wells, i.e North/South (NS), North/East (NE) & East/West (EW). The visualization of error sources will provide a more focused approach towards ultimately reducing the WPU.

The work in this paper is a part of a new digital well planning and well construction software tool. The working title of this software is Life Cycle Well Integrity Model – LCWIM.
Experience Using Managed Pressure Cementing Techniques with Riserless Mud Recovery and Controlled Mud Level in the Barents Sea

Published: April 2018

The Barents Sea offers unique drilling challenges related to issues such as biogenetic gas in shallow formations, thermogenic gas seeps up to the seabed from underlying formations, shallow formations with abnormal pressure, shallow reservoirs, low-fracture-pressure formations in part of the overburden, and naturally fractured/karstified carbonate reservoirs. This paper discusses cementing challenges when drilling wells in the Barents Sea and the experience gained using managed pressure cementing (MPC) practices.

When drilling the surface hole in potentially slightly overpressured formations, the riserless mud recovery (RMR) technique was used. For the first time on the Norwegian Continental Shelf (NCS), MPC was used when cementing the surface casing. RMR compensates for drilling the overpressurized zones without a riser and blowout preventer (BOP), and MPC allows for pressurization and monitoring of the pressure on the subsea wellhead toward the formation during the cement curing stage.

Once the marine riser and BOP were installed, controlled mud level (CML) technology was used during drilling, running casing/liners, cementing operations, and other activities. CML enables manipulation of the fluid level in the riser and therefore helps optimize downhole pressure to avoid losses and maintain an overbalance. CML has proven to be particularly useful during cementing of liners in naturally fractured reservoirs and during setting of balanced cement plugs in an open hole. As a result, high circulation rates can be achieved and conventional high-density cement slurries can be used.

MPC using either RMR or CML was employed for the first time in the Barents Sea. Examples of how cementing operations were planned and executed are described and results are presented.
Via de sinalização do Fator de Necrose Tumoral alfa (TNF-α), síntese e liberação no exercício físico

Published: April 2018

Nos últimos anos inúmeros estudos tem retratado o Fator de Necrose Tumoral Alfa (TNF-α) no exercício físico, sendo considerada uma citocina usualmente presente na resposta imunológica mediada por células. A presente revisão faz uma abordagem do TNF-α, elucidando a sua via de sinalização e se a prática de exercícios físicos favorece a amenização desta citocina pró-inflamatória. Diante dos resultados, foi observado que o TNF-α é reconhecido como um mediador importante em muitos processos inflamatórios e foi possível verificar evidências de que o exercício físico pode atuar como um agente de respostas anti-inflamatórias reduzindo as concentrações de inúmeras citocinas pró-inflamatórias, dentre elas, o TNF-α, podendo auxiliar no controle da inflamação crônica observado na obesidade. Ainda não está totalmente elucidada qual a melhor relação volume, intensidade e frequência de exercícios para potencializar os resultados.Descritores: Fator de Necrose Tumoral alfa; Exercício; Inflamação.
Alternativas para minimizar a degradação da interface adesiva de restaurações dentais: revisão da literatura

Published: April 2018

A grande demanda por restaurações estéticas tem propiciado o desenvolvimento constante de materiais resinosos. Entretanto, mesmo com a evolução destes materiais e o aprimoramento do procedimento de adesão, as restaurações dentais adesivas falham em longo prazo. A interface de união dentina-restauração é passível de degradação, sendo dois os principais mecanismos relacionados à hidrólise e proteólise. O objetivo neste estudo foi, por meio de uma revisão da literatura, abordar e discutir os mecanismos relacionados à degradação da interface adesiva e técnicas alternativas para minimizar a degradação da interface de união à dentina em restaurações adesivas diretas. As estratégias se baseiam em melhorar a impregnação do adesivo na dentina desmineralizada, aumentar a resistência do polímero formado pelos sistemas adesivos e a resistência das fibrilas colágenas à degradação enzimática. Desta forma, se essas técnicas forem usadas com objetivo de minimizar a degradação da interface de união à dentina em restaurações adesivas diretas, uma maior longevidade clínica é esperada.Descritores: Adesivos Dentinários; Falha de Restauração Dentária; Inibidores de Proteases.
