Published: March 2018

Abstract
Cuu Long basin is a Cenozoic rift basin located in the southeastern shelf of S.R. Vietnam, containing vast potential oil and gas resources. The basin was impacted by three main tectonic periods of pre-rift, syn-rift and post-rift tectonism. Major petroleum plays in Cuu Long basin are the Pre-Cenozoic fractured basement, Oligocene and lower Miocene sandstone reservoirs. Upper Oligocene sediments were deposited during late syn-rift phase of Cuu Long basin. The reservoirs in these strata (Oligocene C and D) were previously discovered in the center, southwestern and southeastern margins of Cuu Long basin with limited total reserves, up to 5%, of Cuu Long basin's discovered reserves. Recent exploration and appraisal results of St, Tg, Rg, Ct etc. show a greater potential of upper Oligocene reservoirs with a greater variety of trap types in many areas of Cuu Long basin than that of previous assessments. Therefore, additional studies and assessments of recently discovered trap types need to be carried out for the Cuu Long basin exploration and appraisal program. This article discusses the assessments of upper Oligocene trap types and identifications of several trap mechanisms utilizing the integration of exploration methods. The research results permit better understanding of the trapping mechanisms and possible distributions of various trap types in the upper Oligocene strata of the Cuu Long basin, thus leading to better planning of exploration/appraisal strategies in the basin.

Published: March 2018

Abstract
Hydrocarbons are the major source of energy. Its increasing demand has made the hydrocarbon exploration go beyond the shore. Offshore Rig power requirements are higher compared to onshore rigs. Diesel Generators are conventionally used for the power requirements of offshore rigs. This paper aims to suggest an idea to use the renewable sources of energy (mainly tidal energy) for energy generation in offshore.
The idea is to have a Hybrid energy system, in which both the renewable and non-renewable sources of energy can co-exist together in a symbiotic relationship. The energy harnessed from tidal-waves shall be used to meet the power requirements of offshore rig alongside the diesel generator. This would result in overall more efficient and cost effective energy generation. Wave energy would be harnessed on wave energy harvester system platforms installed around the offshore rig set-up; on which the motion of floats would be transferred via hydraulics into rotation of generator which will produce electricity. The energy generated would be transferred to rig via wires and can be stored in batteries for transportation to land to meet other power requirements.
An analysis of tides/waves generation is detailed. Available data for prototype of Wave Star Energy harvester is examined followed by Monetary-Energy Capacity analysis. SWOT analysis and environmental impacts are discussed. Various parameters affecting the Tidal energy generation are scrutinized. There is a need of an alternative source of energy in offshore rigs because of high environmental impact of diesel generators and other problems associated with it.
Given the current global scenario and advancements in Electric automobile market, there is an exigency for a Hybrid energy system to meet the upcoming energy needs and boost the Global Energy Infra.
A Mathematical Model for Oil Spill Clean up Using Ferromagnetic Nanoparticles

Published: March 2018

Abstract
Permanent environmental damage cannot be compensated in terms of money. Unfortunately, oil spills contaminate water, restraining marine species of their habitat and food supply. Despite the numerous methods available today to clean up the water body affected by an oil spill by separation of oil and water, none have restored water to its previous quality or saved marine animals from its deleterious effects to the full extent. The biggest hurdle to this cause is the sunken oil; the oil which may have either sunken mixed with sand and mud or by dispersion due to weathering.
Ferro fluids are Fe3O4 based Magnetic Nano Particles (MNPs) which can be coated with a layer of polymer or surfactant to form a super-hydrophobic material which selectively adsorbs oil. This work involves coating the MNPs with Polyvinyl-pyrrolidone Styrene and Sodium Oleate. These colloidal ferromagnetic Nano-particles display considerably higher magnetic susceptibility. The MNPs are non-toxic nano sized sponges that sink deep inside the water body, adsorb 10 times their weight of oil and float back to the surface. It must be well-known that electrostatic attraction between negatively charged oil-in-water emulsions and positively charged MNPs controls the attachment of MNPs to the droplet surface; and the subsequent aggregation of the electrically neutral MNPs-attached oil droplets shows a critical role for accelerated and capable magnetic separation.
During the experimental work performed, it was seen that after separating out the recovered oil, the MNPs can be regenerated and re-used. In this work, a 1-D mathematical model was developed for describing the dynamics of the action of the MNPs for oil spill cleanup and its collection in the framework of the sedimentation theory. The model was based on Newton's law of Motion, theory of batch sedimentation, Settling velocity and Stokes-Einstein equation. In order to completely understand the process and to formulate a model that correctly and aptly mimics the experimental observations, the conservation equation for MNPs was also coupled with the flux function, which accounted for gravity force, magnetic force and Brownian interaction. Parameters like offshore constraints and weather conditions were considered while running the model, to make the model more robust, as well as to observe the impact on final obtained results.

Published: March 2018

Abstract
This paper highlights an innovative approach where Multibeam Echosounder (MBES) and sub-bottom profiler (SBP) survey results in addition to conventional seismic data were utilized to demarcate locations for shallow coring. Multibeam and Shallow geochemical studies were planned to further de-risk hydrocarbon potential in frontier exploration areas. Following detailed 2D seismic interpretation, MBES survey area and 100 shallow cores were planned. The interpreted MBES data was used to pin point the final shallow core points. Due to the unfavorable weather window, the survey could not be fully completed. Hence, the remaining area was evaluated by an improvised workflow using preliminary processed 3D seismic data (seabed horizon slice) to fulfil the gap. This allows all proposed coring points to be evaluated. Numerous features like seabed scarps, wave form seabed, seabed mounds, and seabed depressions were identified on top of the observations of a number of active gas seepages and pockmarks. A notably hard seabed was encountered during the seabed sampling operations which resulted in low core recovery. The team effort in improvising a different workflow to identify various sea bed features and also demarcating shallow core location through integrating various geophysical data was very much useful.
A Practical Riser Restrain Solution for Enhancing Drilling Operability in Harsh Environment Scenarios

Published: March 2018

Abstract
Offshore drilling for exploration and scientific purposes in deep waters and subjected to harsh environments due to high current or extreme waves, or a combination of both has been a challenge for decades and lacks a complete and robust solution to allow reliable and continuous drilling operations. A unique riser restraining system is presented in this paper for improving the operability windows of drilling rigs in harsh environments. The restraining system restricts transverse deflection of the risers due to high current drag forces and coupled dynamic motions due to extreme waves that cause potential clashes with the moonpool. The restraining system proposed in this paper uses a modified tensioning ring to act as a centralizer, which is connected to hydro-pneumatic tensioners in the lateral plane for providing retention resistance and attached to removable support structures fixed to the moonpool decks. The customized upper and lower restraining joints are used for interfacing the riser system with the centralizing tensioner ring along with treble slips joint, intermediate flex joints and PUP joints to ensure smooth load transfer and reduce stress concentrations on the connection interface.
A thorough review was carried out on some of the potential offshore drilling locations that are exposed to extreme environments. These assessments were used to generate wave and current combination and three different water depths were defined to establish the design basis for analyzing the system. Numerical analysis using time domain simulations were carried out to check the global and local strength integrity of the system. The results were utilized to benchmark the improvement in operability of the riser system with the restraining solution as compared to conventional systems with and without fairings. Simulations with the proposed restraining system show that the exceedances of key parameters like flex joint angles and riser clashes with moonpool deck are reduced to significant levels while maintaining the stress envelopes within allowable limits.
Generic modifications required for implementing on existing drillships and semisubmersibles are also highlighted. The overall global and local strength integrity of the system and significant improvement in operability window are presented to demonstrate the benefits of the proposed system.
A Comprehensive Model for After-Closure Analysis of DFIT by Considering Natural Fractures

Published: March 2018

Abstract
For unconventional wells, diagnostic fracture-injection/falloff tests (DFIT) has become the standard well testing approach. However, very limited work has considered the natural fractures. The objective of this study is to develop a comprehensive model for after-closure analysis (ACA), which may help the operatorsto perform a more successful DFIT design. The comprehensive model is based on a semi-analytical model, which can simulate the DFIT by considering natural fractures. The semi-analytical approach is verified by a numerical simulator. We use the proposed model to analyze the DFIT data of a complex fracture case, namely complex fracture networks. The impacts of fractures on pressure behaviors are also studied with sensitivity analysis. It is found that the flow regime is not a single simple bilinear/linear flow during DFIT, and the pressure behaviors exhibit a dual-porosity feature "V-shape" in which pressure derivatives decrease rapidly until they reach a minimum. It is demonstrated that the standard well test analysis based on bilinear/linear flow may need improvements for ACA. Its applicability and robustness are demonstrated by using examples from a synthetic DFIT tests in unconventional reservoirs. This work may shed light on a more successful estimation of DFIT data in unconventional reservoirs.

Abstract
Gas hydrate production commenced from two production wells drilled in 1,000 m of water in the Nankai Trough, Japan, in May 2016. Two adjacent monitoring wells were drilled to monitor the in-situ event change of the hydrate reservoir over a two-year monitoring period. To achieve this monitoring purpose, an innovative design of wellbore gauges was installed downhole to provide valuable temperature and pressure data to show the dynamic nature of the gas hydrate dissociation front.
Using two seabed located autonomous subsea monitoring systems, data were continually logged from the monitoring gauges since they were installed in May 2016. To gain access to the recorded wellbore data, early project thoughts revolved around either recovering the large subsea monitoring systems or deploying remotely operated vehicles (ROVs) to tieback umbilical cables from the two subsea monitoring systems to the drillship, once it arrived at the field site. These techniques proved to be expensive and of increased risk to both personnel and equipment.
With a view to future safe and more cost-effective data harvesting techniques, a project was instigated to investigate using autonomous, unmanned surface vehicle (USV) along with vessel-based "dunker" methods to upload data from each of the monitoring wells using integrated high telemetry acoustic modem technology. The main objectives of the study were to verify data could be harvested and delivered to the client using a USV along with safe and repeatable piloting of the USV from a remote location.
Two USV missions have since been conducted, one in June 2016 and the other in March 2017. Lessons learnt from the initial USV mission, such as higher than expected sea surface currents and thrust limitations of the USV, were incorporated into the second deployment. This resulted in roughly 200 days' worth of data being uploaded and delivered from each of the two monitoring wells.
In this paper, we will outline how the project objectives were met and how some of the challenges, both technical and environmental, were overcome.

Published: March 2018

Abstract
In this study, we examined the effectiveness of a community-based, occupational therapy intervention situated within an intensive comprehensive aphasia program (ICAP). Occupational therapy interventions addressed goals of participants with chronic stroke and aphasia for improving their satisfaction with and performance of instrumental activities of daily living, social participation, leisure, work, and volunteer activities. Over 3 yr, 19 people with chronic stroke and aphasia participated in a month-long, intensive, interprofessional, community-based program. Significant improvement in participation in valued activities was demonstrated on the Canadian Occupational Performance Measure (p &lt; .01), goal attainment scaling (p &lt; .01), and two domains of the Stroke Impact Scale (p &lt; .05). We conclude that occupational therapy using collaborative goal setting and problem solving as part of an interprofessional team may be an important component to include in ICAPs to address functional participation goals.
GLOFs in the WOS: bibliometrics, geographies and global trends of research on glacial lake outburst floods (Web of Science, 1979–2016)
Authors: Emmer Adam 
Published: March 2018

Abstract. Research on glacial lake outburst floods (GLOFs) – specific low-frequency, high-magnitude floods originating in glacial lakes, including jökulhlaups – is well justified in the context of glacier ice loss and glacial lake evolution in glacierized areas all over the world. Increasing GLOF research activities, which are documented by the increasing number of published research items, have been observed in the past few decades; however, comprehensive insight into the GLOF research community, its global bibliometrics, geographies and trends in research is missing. To fill this gap, a set of 892 GLOF research items published in the Web of Science database covering the period 1979–2016 was analysed. General bibliometric characteristics, citations and references were analysed, revealing a certain change in the publishing paradigm over time. Furthermore, the global geographies of research on GLOFs were studied, focusing on (i) where GLOFs are studied, (ii) who studies GLOFs, (iii) the export of research on GLOFs and (iv) international collaboration. The observed trends and links to the challenges ahead are discussed and placed in a broader context.
Machiavelli's Two Utopias
Authors: Holman Christopher 
Published: March 2018

ABSTRACT
This article interrogates the form of the relationship between political theory and utopia through a consideration of the thought of Niccolò Machiavelli. This article argues that Machiavelli can be read as an exemplary theorist of utopia who gives expression to the antinomies internal to the tradition. It identifies in Machiavelli's thought two distinct models of utopia that exist in uneasy tension with one another: the thought of utopia as a critical expression of the inexhaustible human desire to be otherwise and the thought of utopia as an object to be fabricated by an instrumentally rational subject. After demonstrating the nature of the tension between these two utopias—and how they generate distinct conceptions of politics that differ in their relation to democracy—this article concludes by locating in Machiavelli's thought a germinal mode for overcoming the utopian contradiction, potentially allowing for a more productive relation between political theory and the utopian tradition.
Planificación ecológica en Santiago de Chile. ¿Qué tan lejos estamos? Clasificación de iniciativas de planificación territorial basadas en una breve revisión bibliográfica
Authors: Picón María Catalina , De la Barrera Francisco , Reyes Sonia , Forray Rossana , Berrizbeitia Anita 
Published: March 2018

Para mediados del siglo XXI de espera más del 65% de la población mundial viva en áreas urbanas, situación que requerirá la conversión de áreas naturales en zonas urbanas. La inclusión de estas áreas naturales plantea nuevos
desafíos para la planificación territorial que se pueden abordar por un nuevo enfoque que incorpora características del entorno natural. Este nuevo enfoque se denomina planificación ecológica. El objetivo de este estudio es comprender
las tendencias de planificación actuales en la ciudad Santiago, capital de Chile, y cómo las iniciativas de planificación territorial se han desarrollan en relación a los conceptos inherentes a la planificación ecológica. Para lograr esto, realizamos una revisión bibliográfica general sobre planificación ecológica y un estudio de las iniciativas de planificación desarrolladas en Santiago. Nuestros resultados indican que la planificación urbana en Santiago se ha centrado en tres conjuntos de conceptos de planificación ecológica. Primero, dentro del área urbana, hay un conjunto de instrumentos e iniciativas que reducen la incorporación de la ecología a la planificación de áreas verdes. El segundo
grupo, implementado fuera del área urbana, se enfoca en la planificación de la biodiversidad y la naturaleza. El tercero, un conjunto más amplio de conceptos, asocia los grupos antes mencionados a conceptos relacionados con
la ecología del paisaje. No es común encontrar iniciativas que promuevan conceptos como corredores y entornos naturales para mejorar la calidad de vida. En cambio, hay conceptos no incorporados como resiliencia, infraestructura urbana, sustentabilidad y cambio climático. En general, creemos que la incorporación de conceptos contemporáneos es necesaria para poder implementar una planificación con enfoque ecológico en la ciudad de Santiago, ya que lograría comprenderla como una región urbana con ecosistemas urbanos y periurbanos integrados.
Genealogía del patrimonio arquitectónico: De documento histórico a recurso reutilizable.
Authors: Lorenzo Aspres Alberta 
Published: March 2018

Desde la Rehabilitación –entendida como la reutilización de un edificio para un fin diferente al que fue erigido–, vemos cómo el cambio de uso ha sido una constante en la Historia de la Arquitectura, transformando la edificación original en otra construcción híbrida, enriqueciéndola en muchos casos y desvirtuándola en otros.
La actitud frente a estas actuaciones evolucionó paralela a la valoración del Patrimonio, apareciendo diversas corrientes que buscaban garantizar la permanencia del monumento en el tiempo a pesar del cambio de uso. En relación se celebraron numerosos congresos en los que debatir sobre unas pautas fundamentales de actuación. Y entre ambos polos de pensamiento se establecieron unos nexos que conformaron un marco legislativo que incidiría en el desarrollo teórico y práctico de la intervención monumental.
Medicinas alternativas e holísticas e a política nacional de práticas integrativas e complementares em saúde- desafios da atualidade
Authors: Velloso Adriana de Freitas 
Published: March 2018

As terapias alternativas e holísticas integraram o movimento contra cultural iniciado na década de 60. Impulsionadas pelas transformações sociais da época, inaugurou-se no campo da saúde do Ocidente, um período de convivência de diversas culturas de saúde.Nos anos 80, intensificou-se a demanda por formas não convencionais de consumo de bens e serviços de saúde, entre eles a homeopatia, fitoterapia e práticas da medicina chinesa, mais especificamente a acupuntura. Havia uma nova sensibilidade cultural que buscou fundar, entre outras propostas, uma inédita postura de promoção de saúde, diferenciada do preventivismo médico até então vigente. Nascia um novo paradigma no campo da saúde, cujo objeto e objetivos eram distintos do tradicional combate às doenças. A existência desse movimento social, aliado às lacunas deixadas pela medicina científica contemporânea no atendimento às demandas de saúde da população, levou à institucionalização das práticas integrativas e complementares, uma trajetória que levou em 2006 à publicação da portaria n° 971 que define a Política Nacional de Práticas Integrativas e Complementares (PNPIC) no SUS. Nesta apresentação propomos discutir os desafios atuais para a disseminação das PICs no SUS e, em especial,nos Núcleos de Apoio à Saúde da Família (NASF), onde estão oficialmente inseridas, na perspectiva do movimento cultural original, da promoção da saúde e de suas novas bases paradigmáticas.
