Authors: Moussa Tamer , Mahmoud Mohamed , Patil Shirish , Elkatatny Salaheldin , Abdelgawad Khaled 
Published: December 2018

Abstract
Thermal recovery methods are viable and commonly used to recover heavy oil reservoirs by reducing oil viscosity and improving oil displacement. However, there are many challenges associated with conventional steam injection methods. These challenges include the significant heat energy losses before steam reaches the reservoir, the high cost of steam generation and injection, as well as the emission of greenhouse gases. Therefore, it is essential to introduce a heavy oil recovery approach in which steam can be generated downhole to overcome these challenges associated with conventional steam injection methods. However, this novel heavy-oil recovery method has several designs and operational parameters that must be efficiently optimized, to achieve maximum recovery from heavy-oil reservoirs with less cost and minimum environmental impact.
The objective of this work is to introduce a novel heavy-oil recovery technique using in-situ steam generated by downhole thermochemical reactions and investigate the key design and operational parameters of this complex recovery process. Modified self-adaptive differential evolution (MSaDE) and particle swarm optimization (PSO) methods are used in this work as global optimizer to find the optimum design and operation parameters to achieve the maximum net present value (NPV) and highest oil recovery (RF) of a heavy-oil reservoir after ten years of development. Comparison of the two proposed optimization methods is introduced as well.
The results show that downhole thermochemical reactions can be used to generate in-situ steam, to efficiently reduce the heavy-oil viscosity and improve oil mobility. It has also shown that utilizing MSaDE and PSO methods to optimize the key components of this novel recovery process, significantly enhanced the recovery performance, in terms of higher NPV and RF.
This study provides the first known in-depth optimization and uncertainty analysis to outline the significance of each design and operation parameter of the proposed novel thermochemical recovery process. This work showed and verified the concept of using downhole thermochemical reactions as an environmental-friendly solution to recover oil from heavy-oil reservoirs and is considered as a step forward to eliminate the greenhouse gases emission related to thermal recovery methods.

Published: December 2018

Abstract
Production in a green, heavy oil field in Northern Kuwait with limited production history is in a fast track delivery to increase production in the short term. A fast but insightful evaluation was required to identify field-wide productivity enhancement opportunities needed to increase oil production. A parametric analysis methodology was applied to a "typical well" to first obtain the factors that limit the well's production thorough understanding of the overall well potential, to finaly identify inflow and outflow enhancement opportunities.
Nodal analysis based on Darcy inflow model was utilized and multiple sensitivities were run for parameters prevoisuly identified. The parameters were expanded in value considering possible technical solutions applicable but not limited to: completion and perforation design, artificial lift performance and surface equipment, in order to determine technical limits applicable for each parameter using a combination of proven and novel technologies.
The parametric analysis helped to identify inflow and outflow enhancement opportunities (from the sand face to the separator), including but not limited to: well stimulation, re-perforation, pump efficiency and back pressure reduction. The range of the theoretical oil rate improvement identified from the analysis was from 20 to 50%. Based on the model results, additional resources were alloactred for a more detailed validation and study work using simulation. The parametric modeling approach was subsequently crosschecked on individual well reviews, where detailed inflow and outflow evaluations were conducted resulting in good agreement in terms of value in production gains.
The applied methodology showed to be a valid and fast track approach, readily to identify field-wide production issues and opportunities, particularly at the start of field production. The results obtained from this study provide a comprehensive approach to understand how well design, engineering decisions and field operational practices will impact well productivity. The methodology can be easily replicated by engineers in similar fields.

Abstract
""A challenge only becomes an obstacle when you bow to it — Ray A. Davis". The development of heavy oil resources at North Kuwait Fields is an important strategic project for Kuwait Oil Company (KOC). With the target of reaching 4 million barrels per day (MBPD) production capacity by the year 2020, KOC is expected to produce 900,000 BPD of heavy oil by the year 2020. However, while cruising towards this ambitious target, KOC is also facing some unique HSE challenges - risk of exposure to high concentration of Hydrogen Sulphide (H2S) especially in the Heavy Oil Fields. The objective of this paper is to present KOC's strategies in the management of H2S in heavy oil drilling and processing activities.
Various controls including access control, mandatory H2S Awareness and Escape training courses for personnel, provision of fixed and portable H2S detectors, facility alarms, emergency planning, PPEs including respiratory protective equipment, work permits etc. are strictly implemented across the Facilities. All personnel working in heavy oil Facilities are trained for emergency to ensure that they react to protect themselves (and others) in the event of an H2S release incident.
This paper introduces some practical strategies adopted in KOC to handle H2S hazards, which have contributed in effective management of the associated risks in "sour gas handling in heavy oil drilling and process plants". It is expected that this paper will initiate further consideration and new measures/ways to enhance H2S risk management and thereby significantly reduce the occurrence of losses to personnel, environment, asset and reputation. From our experience, we feel that the effectiveness of the overall H2S risk management can be ensured by establishing a structured system consisting of proper identification of the hazards, assessment of risk, identification of control measures to contain the risks at ALARP level and dissemination of information amongst the workforce.
Experimental Investigation of Nanoparticles/Polymer Enhanced CO2- Foam in the Presence of Hydrocarbon at High-Temperature Conditions

Published: December 2018

Abstract
This study, aims to investigate the effect of nanoparticles/polymer on CO2-foam stability and foamability of Alpha Olefin Sulfonate, AOS at high temperature and salinity conditions. Moreover, the effect of extra hydrocarbon phase on foam stability at high temperature and salinity conditions is studied. Static CO2-foam experiments were conducted according to ASTM: D3601 standard method for bulk foam stability in aqueous media, to analyse the foam half-life and its real time stability with nanoparticles and polymer at high temperature and salinity conditions in the presence of hydrocarbons. The average bubbles size distribution and foam texture were analysed using an Olympus stereo microscope SZX100 equipped with 5 mp camera.
The results show that the CO2-foam stability enhanced with increasing nanoparticles/polymer concentrations up to threshold values. The optimum concentrations to achieve the maximum stability were 0.2 wt% and 0.3 wt% for silica and xanthan gum, respectively.
In order to understand the performance of the optimum foam composition in presence of extra hydrocarbon phase at reservoir condition, foam then brought into contact with a North Sea oil sample. The results shown that the foam stability was not changed when oil saturation increase up to 3.0 vol%, but was completely deteriorated when the concentration reaches 40.0 vol%.
This study suggests that optimum concentrations of nanoparticles and polymer at a high temperature and salinity conditions should be determined before the design of any foam-based enhanced oil recovery process.
Seismic Facies Classification and Rock Typing to Better Understand Heavy Oil Reservoirs: A Case Study from North Kuwait

Published: December 2018

Abstract
This paper describes seismic attributes approaches and rock typing in channelized reservoirs of North Kuwait. Seismic facies with a range of frequencies from 10 - 50 Hz, along with four other attributes: semblance, RMS frequency, instantaneous phase, relative acoustic impedance and RMS amplitude of shallow upper Cretaceous channelized system are calculated and the channel infill and overbank deposits are represented in maps. Five classes are used and found to be sufficient in the unsupervised classification method. The seismic facies classification was matched against the above-mentioned four attributes and found to correspond to them. The major channel components are illustrated with the figure 1. Additionally, the seismic facies classification workflow is summarized in figure 4. Results of seismic facies classification using Neuronal classification and log-based rock typing are illustrated in figures 11, 12, 13 & 21. The lessons learned from the use of different seismic attributes and rock typing in such heavy oil reservoirs are discussed.
Steam injections in shallow heavy oil targets come with a risk of breaching the thin cap shale sealing layer and not fully understanding the thickness and continuity of shale barriers within the reservoirs. This paper presents an investigation to mitigate those risks through different seismic attributes and rock typing for shallow Tertiary and Cretaceous reservoirs in North Kuwait which extended to a deeper heavy oil targets in neighboring fields. This work that studies all the key risk elements in such heavy oil reservoirs mitigates the drilling and steam injection risks of heavy oil field development. Those who utilize seismic data to map heterogeneities must realize that the changes we observe in our seismic events can be due to one of the following items: depositional environments, sweet spots, stratigraphic features, lithology, petrophysical properties such as porosity or fluid or clay content, geohazards, etc.
From a previous study presented this year at Geo 2018 for Tertiary targets, we concluded that Simultaneous geostatistical inversion (SGI) added much value in terms of delineating the shale barriers and enhancing resolution, in addition to estimating effective porosity for well releases.

Abstract
The biological conventional removal of nitrogen is achieved through nitrification and denitrification steps using several types of technologies, including fixed-film reactors. This type of technology allows the nitrifying bacteria to grow on a media that remains inside the reactor. This process requires tight control and is known to progressively clog during treatment as the filtered particles accumulate and biofilm grows on the media. Thus, clogging management is generally considered as a key factor in biofiltration. So, increasing the filtration time and reducing the number of backwashes are possible ways of achieving a more efficient nitrification step. The objective of the work presented here is to verify the influence of a media, named K5, added to the Biostyr® beads inside a biofilter. With a greater density than Biostyr® beads, this media stays at the bottom of the biofilter and improves operating conditions, reducing both the headloss during filtration time and the number of backwashes. The addition of such media in biofilters may reduce significantly the energy consumption of the process and the risk of hydraulic short-circuiting while limiting biofilter clogging.
Towards a sustainable city: planning the fulfilment of urban fresh water needs of Depok in both dry and rainy seasons
Authors: Herdiansyah Herdis , Putra Gede Aswin Yoga 
Published: December 2018

Abstract
Population growth over recent years in Depok has increased demand for fresh water for daily necessities. These necessities include the fresh water required by both settlements and commercial operations. The purpose of this study is to analyse the demand for fresh water created by the population growth of Depok in realising its development as a sustainable city. This study uses a quantitative approach presented through narrative analysis. In 2016, the average water requirement of Depok's population of 2,180,000 people was 3,070 litres/second in the dry season and 5,983 litres/second in the rainy season. Population projections for 2030 suggest that the population of Depok will have increased to 3,543,101 people, and that the average water requirement will then be 4,990 litres/second in the dry season and 9,724 litres/second in the rainy season. Planning alternatives proposed to meet these needs include improving the evaluation of freshwater production capacity and developing freshwater supply systems. Thus, it expected that the projected freshwater needs of Depok in 2030 can be fulfilled. This expectation can be managed and achieved through participation by society and government. However, obstacles are still faced, mainly due to more recent cultural attitudes towards using water.

Authors: Pitt R. E. , Clark S. E. , Steets B. 
Published: December 2018

Abstract
The Santa Susana Field Laboratory (SSFL) occupies about 2,850 acres and is located in Ventura County, California. The site is jointly owned by the Boeing Company and the federal government (the National Aeronautics and Space Administration administers the federal portion of the property). Much of the site was historically used as a rocket engine testing and energy research facility from 1949 to 1998. The site stormwater discharges are permitted by the Los Angeles Regional Water Quality Control Board through an individual industrial NPDES permit that includes numeric effluent limits for a wide range of constituents, including dioxins and metals. A large portion of the site uses distributed source stormwater controls with natural treatment systems utilizing chemically active media. As part of this approach, extensive research was conducted to develop a robust media for use in these controls to meet the discharge objectives. This paper describes the development of the media and its characteristics.

Published: December 2018

Abstract
Traditional, mandatory water efficiency requirements such as maximum allowable flow rates for taps and showers, as well as water efficiency labelling for water fittings and appliances (taps, mixers, dual flush low capacity water closets (LCWCs), urinals and urinal flush valves, and washing machines) have helped achieve remarkable reductions in per capita household consumption over the years. To further boost domestic sector water conservation efforts in line with the vision for a Smart Nation where people are empowered by technology to improve living, PUB will seek to gain a deeper understanding of household water use patterns and habits, as well as what motivates water-saving behaviours. This will enable programmes to be designed and implemented in a more targeted manner. This paper shares the key findings and experiences from two projects – the Smart Shower Programme and the Advanced Metering Infrastructure (AMI) WaterGoWhere Project – whereby smart devices provide the technological means of modifying user attention to achieve greater water conservation.
Improving flood monitoring in rural areas using remote sensing
Authors: Ghofrani Zahra , Sposito Victor , Faggian Robert 
Published: December 2018

Abstract
Precise information on the extent of inundated land is required for flood monitoring, relief, and protective measures. In this paper, two spectral indices, Normalized Difference Water Index (NDWI) and Modified Normalized Difference Water Index (MNDWI), were used to identify inundated areas during heavy rainfall events in the Tarwin catchment, Victoria, Australia, using Landsat-8 OLI imagery. By integrating the assessed condition of levees, this research also explains the inefficiency of the flood control measures of this region of Australia. NDWI and MNDWI indices performed well, but water features were enhanced better in the NDWI-derived image, with an accuracy of 96.04% and Kappa coefficient of 0.83.
Elementos da fenomenologia como uma das possibilidades de compreender o jogo como um movimento humano significativo

Published: December 2018

O presente ensaio tem como objetivo refletir sobre o Jogo como uma das dimensões do lúdico - a par do brincar e do competir. A reflexão vai fazer o elogio ao Jogo como um fim em si mesmo, contrariando a ideia do Jogo como um meio, um instrumento ao serviço de modelos teóricos e didáticos. O Jogo é capaz de emprestar a quem joga um movimento humano significativo, fundado a partir da concepção dialógica do movimento. Neste sentido serão apresentados alguns apontamentos que tornam o Jogo como parte essencial da Educação Física (e da educação em geral) e do movimento humano significativo; dentre eles, podemos citar a subjetividade, a criatividade, o sonho, a vontade, a possibilidade, a liberdade, … como constituintes do ser humano.
Palavras-chave: Jogo; Movimento humano significativo; Subjetividade; Lúdico.

Notas sobre imaginário social e hegemonia cultural
Authors: Moraes Dênis De 
Published: December 2018

O objetivo deste trabalho é estabelecer conexões entre o imaginário social e a hegemonia cultural, para elucidar a
busca pelo consenso que caracteriza e condiciona a produção de sentido na sociedade contemporânea. Parte do pressuposto de que a hegemonia não é uma construção monolítica, e sim o
resultado das medições de forças entre os blocos sociais atuantes em determinado contexto histórico. Nessa perspectiva,
avalia-se que as relações de poder estão atravessadas por contradições que favorecem o surgimento de lutas contra as formas de domínio material e imaterial, através de ações nos campos comunicacional e cultural.

Um outro "Quarto Poder": imprensa e compromisso político no Brasil
Authors: Albuquerque Afonso De 
Published: December 2018

"A eleição das reformas"; "Por que o Brasil desconfia dos políticos".
Os títulos de capa das revistas Época e Veja, em suas edições
imediatamente anteriores às eleições de 1998, constituem um bom ponto de partida para discutir a questão do papel político da imprensa no Brasil. O que estes títulos sugerem? À luz do debate atual sobre o tema poderíamos dizer que o título de Epoca sugere uma atitude francamente governista da revista, enquanto haja reflete velhos preconceitos contra os políticos em geral e (se observarmos o corpo da matéria) contra os parlamentares em particular. E não estaríamos errados. Entretanto, poderíamos encontrar outras lições nesses mesmos enunciados. Época e Veja não estão apenas se pronunciando a favor do governo. ou manifestando desconfiança com relação ao Congresso Nacional; elas estão também demarcando o espaço de uma competência específica: o de fornecer uma interpretação "independente" da cena política transcendente em relação às perspectivas particulares dos agentes políticos envolvidos.
