Published: April 2017

Abstract
The current study area, Raageshwari Deep Gas field is situated in the southern part of onshore Barmer Basin in Rajasthan, India. The field contains a gas condensate reservoir with excellent gas quality within the dominantly volcanic formations (Basalt and Felsic) and overlying clastic Fatehgarh Formation. These are tight reservoirs and optimal field development necessitates reasonable characterization of faults and natural fractures thereby aiding well placement by targeting areas of enhanced permeability for better well performance.
The minor faults with throws significantly less than the duration of the seismic wavelet may not be detected in variance attribute data. However, reflection curvature is an attribute that also relates to structural deformation and shows greater spatial resolution. The detailed structural lineaments revealed through this analysis are indicative of sub-seismic faults and possible increased intensity of natural fractures. The maximum and minimum curvature data help to accentuate small scale reflection geometry changes and can be used to interpret minor faults. To discriminate stratigraphic features and identify fracture zones, careful calibration was done with production data, image logs and microseismic measurements from the wells.
The curvature attributes highlighted lineament distributions, interpreted to be small scale faults and subtle structural deformations associated with fractures. Lineaments of fault/fracture from curvature attributes were observed to correlate with interpretations from borehole image logs. Detected subtle faults were further validated with other measurements like microseismic and production data. These well calibrations provide confidence in the use of specialized seismic attributes for fracture characterization in the field. Results of this study will be used for optimal placement of infill wells for enhanced field productivity.
Mitigation of Work Control Challenges at Well Sites – Lessons from CBM Project
Authors: Pandey Baldev , Tomar Satendra 
Published: April 2017

Abstract
Control of work, a significant element of HSE management system at CBM, Shahdol, MP, is one of the major challenges in term of planning, communication, hazard identification, risk control and safe execution of work.
Challenges associated with Implementation of PTW system at 229 wells, spread in an area of 500 KM2, is quite different and unique in terms of planning, supervision, geographical spread, work efficiency and assurance methodology. Limitations of different permits (Confined space entry, hot work of high risk, and line break of high risk) for permit acceptors and receivers, parallel supervision at different well sites, transportation, and level of permit issuing authorities, warrant a scientific method to be adopted for optimization of numbers of permits, under responsibility of individuals.
In conventional E&P oil and gas fields, the numbers of wells are relatively lesser and in downstream, operation is more or less confined inside boundary walls. CBM activities are wide spread and with large number of wells/assets and pipelines, the activities are around inhabitations and closely interact with villagers, flora and fauna.
Effective control of work at such widely spread large number of assets in CBM is a herculean task and has to be supervised by a limited number of personnel.
It is appreciated that each individual has a physical, mental and psychological limitation in effectively and efficiently controlling work activities.
The detailed paper describes, the mathematical method for optimization of manpower resources for adequate control of job in terms of: What should be categories of permits based on risk involved in work?How many types and quantity of permits should be issued by one individual with variation of well sites (geographical spread)?How many types and quantity of permits should be received by an individual?How many types and quantity of permits can be supervised by area operators?What should be the level of issuing authority for different categories of permit (hot work-high risk, line break of high risk)?
The mathematical method for optimization will consider the following factors: Load factor based on risk involved in the work.Quantity of permits of different types that can be effectively supervised by an individual.Geographical distance between/among the work locations.Constraint factor of time of work (Work during natural light or during silent hours).
On the basis of above factors, a mathematical and logical formula has been developed which gives a quantitative figure called total permit load on an individual (permit issuer and acceptor). Base on capability of people, an upper mathematical limit of total permit load has been fixed. This mathematical formula provides ease in limiting the number of permit with risk involved and eventually will control the work at well sites.
Oil Spill Cleanup Using Aerographene
Authors: Wadhwani Rajat 
Published: April 2017

Abstract
Even in the 21st century, the oil industry is yet to overcome some major problems it faces related to oil spill cleanup. Oil spills can cause a multitude of problems for the environment which may even last for decades after the spill occurs. This paper discusses a novel approach that may provide a complete solution to combat oil spills. Conventional techniques are not adequate to solve the problems of massive oil spills. Graphene based aerogels or Aerographene have attracted widespread attention due to its excellent oleophilicity, hydrophobicity, reusability, high uptake rate of oil, high uptake capacity and recovery of oil. Although the application of graphene aerogel for an oil spill is still in its nascent stage, it offers great promise for the future. It is believed to have potential to replace present sorbents which are used commercially. This paper briefly outlines present oil spill cleanup techniques and problems associated with each technique. A major part of this paper will be on the evaluation of aerographene properties and how it overcomes major problems related to conventional techniques. Many properties of aerographene have been studied which makes aerographene stand a chance of replacing the present oil spill cleanup methods. This paper presents a novel idea by which cleaning up oil spills with the help of aerographene will become much simpler, easier, cheaper and will prevent the environment from degrading at a massive scale due to oil spills.
Successful Polymer Selection for CEOR: Brine Hardness and Mechanical Degradation Considerations

Published: April 2017

Abstract
The selection of the right polymer chemistry in chemical enhanced oil recovery processes is key to successfully increase oil recovery. To start the screening process, it is necessary to look at minimum 3 parameters including brine composition, reservoir temperature and permeability. In addition to simple rheological tests, it is mandatory to evaluate the long-term and shear stabilities of the polymer candidates to ensure that viscosity is maintained over time at an economical concentration. In few cases, the polymer that yields the best results (especially viscosity yield) at an instant t is not always the best compromise when considering long-term stability or shear sensitivity. This paper aims at providing some guidelines to select the optimum chemistry for a wide range of field conditions.
The resistance of different acrylamide and ATBS-based polymers to salinity and shear is evaluated through viscosity measurements over a wide range of brine compositions. A parameter called R+, that reflects brine hardness, is introduced in this study. Brines considered are either with a constant Total Dissolved Salt (TDS) and varying R+ or different total salinities with a constant R+. This parameter is also used to compare shear resistance of the different polymers.
For all the polymers, there is a threshold value of R+ beyond which viscosity remains constant. Interestingly, this threshold is reached for lower value of R+ for polymers containing ATBS, a monomer also well-known to provide calcium tolerance. Increasing the amount of ATBS yields better tolerance to divalent cations and provides shear resistance. A minimum amount of sulfonated monomer is required to improve the overall stability in complex brines.
Some important guidelines are summarized in this paper that can help screen products among a wide range of reservoir conditions in order to find the most suitable candidate for a chemical enhanced oil recovery project.
Optimization of Fracturing Technique for Successful Exploitation of Tight Gas Reservoirs of Mandapeta Field

Published: April 2017

Abstract
Hydraulic fracturing is the proven stimulation technique to exploit hydrocarbon reserves trapped in tight gas Indian reservoirs especially in Mandapeta field of Southern India. Fracturing technique was customized to obtain designed fracture geometry which in turn resulted in very good post frac gas production rates. This paper deals in detail, the necessity of fracturing in Mandapeta field, meager production gains obtained in earlier fracturing treatments, challenges for fracturing, quality assurance and quality control of fracturing fluid, design and successful execution of fracturing technique.
Mandapeta field is located in Krishna Godavari Basin situated in Southern part of India. Customization of fracturing technique produced impressive gas production rates from Mandapeta field compared to earlier treatments. Poor geophysical properties of the reservoir, leak-off characteristics, completion constraints and high near wellbore frictions were some of the challenges observed during fracturing treatments. As the reservoir is having very low permeability, hybrid fracturing treatment with a pad comprising around 75 percent linear / slick gel followed by cross-linked slurry was designed and implemented successfully.
Gas production gains up to 37000m3/d in a single well was observed. 20/40 mesh high strength proppant was used in these treatments and maximum job size pumped was 151MT. Hybrid frac treatment was carried out in an exploratory location which resulted in impressive gas gain paving a way to further development of field. Pre-frac acid treatments improved the well bore connectivity to the reservoir thereby enabling the higher proppant concentrations to pump during the treatments. Chemical compositions addressed the surface tension and mobility concerns of the fracturing in gas reservoirs which resulted in faster cleanup and gas production. Recent successes of fracturing made a way forward to aggressive fracturing campaigns in this field.
Hydraulic fracturing treatments have to be customized to specific reservoir conditions so as to obtain success. Candidate selection, modeling designs using sensitivity analysis, suitable pre-frac treatments, lab studies for optimization of fracturing fluid, customized hybrid fracture treatments played vital role in successful execution of fracturing treatments in Mandapeta field of Southern India which can be applied to other tight gas reservoirs.
Recent Trends in Wastewater Flow and Pollutant Load Resulting from Urbanization in Shanghai
Authors: Liu Chen , Huang Tao 
Published: April 2017

ABSTRACT:To better control water pollution and to manage water resources, we used input‐output analysis to examine structural changes in wastewater flows and pollutant loads following changes in socioeconomic activities in Shanghai. We found that the industrial structure has changed considerably and that total direct emission loads exhibited a decreasing trend between 1997 and 2007. Emission loads from secondary industries, especially from paper manufacturing, have decreased. However, wastewater from primary industries remained constant while wastewater from tertiary industries and domestic sources increased, acting as the largest sources of emission loads since 2002. Wastewater and pollutant loads from household consumption, including indirect sources from food manufacturing, clothing, and transportation, had an especially large influence on emission loads in 2007. These emissions were primarily generated through primary industries and food manufacturing sectors. With continued urbanization, wastewater and pollutants generated by household consumption should be factored into the control of water pollution in Shanghai.

Authors: Manns Liam , Scott-Douglas Nairne , Tonelli Marcello , Weaver Robert , Tam-Tham Helen , Chong Christy , Hemmelgarn Brenda 
Published: April 2017

Background and objectives
Awareness of CKD remains low in comparison with other chronic diseases, such as diabetes, leading to low use of preventive medications and appropriate testing. The objective of this study was to evaluate the quality of care provided to people with and at risk of CKD.

Design, setting, participants, & measurements
We conducted a population-based analysis of all Albertans with eGFR=15–59 ml/min per 1.73 m2 between April 1, 2011 and March 31, 2012 as well as patients with diabetes (as of March 31, 2012). We assessed multiple quality indicators in people with eGFR=15–59 ml/min per 1.73 m2, including appropriate risk stratification with albuminuria testing and preventive medication use and screened people with diabetes using urine albumin-to-creatinine ratio and serum creatinine measurements.

Results
Among 96,480 adults with eGFR=15–59 ml/min per 1.73 m2, we found that 17.0% of those without diabetes were appropriately risk stratified with a measure of albuminuria compared with 64.2% of those with diabetes (P<0.001). Of those with eGFR=15–59 ml/min per 1.73 m2 and moderate or severe albuminuria, 63.2% of those without diabetes received an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker compared with 82.1% in those with diabetes (P<0.001). Statin use was also significantly lower in patients with eGFR=15–59 ml/min per 1.73 m2 without diabetes (39.2%) compared with those with diabetes (64.6%; P<0.001). Among 235,649 adults with diabetes, only 41.8% received a urine albumin-to-creatinine ratio and 73.2% received a serum creatinine measurement over 1 year.

Conclusions
We identified large gaps in care, especially in those with CKD but no diabetes. The largest gap was in the prescription of guideline-concordant medication in those with CKD as well as appropriate screening for albuminuria in those with diabetes. Our work illustrates the importance of measuring health system performance as the first step in a quality improvement process to improve care and outcomes in CKD.
Third Sector Organizations in Québec and the New Public Action in Community Development
Authors: Savard Sebastien , Bourque Denis , Lachapelle René 
Published: April 2017

This article presents the context for and particular relations between the state and third-sector organizations in the province of Québec. A typology inspired by Coston and developed by Proulx, Bourque, and Savard is used to describe interactions between these actors. The article documents how an agreement that the private Fondation Lucie et André Chagnon signed with the Government of Québec had an impact on community organizations that respond to the social needs of vulnerable groups. A major repercussion has been the relegation of third-sector organizations to a model between subcontracting and coproductive. This is notable, as the sector had managed to establish itself as a central actor during the previous twenty years, particularly in health and social services, participating in the co-construction of public policies. RÉSUMÉ Cet article aborde la question des relations entre les organismes communautaires et l’État au Québec en mettant l’accent sur le contexte particulier et les dimensions qui les distinguent dans cette province. Une typologie adaptée de Coston par Proulx, Bourque et Savard est utilisée pour encadrer cette réflexion. Nous discutons de l’impact de l’arrivée de la Fondation Lucie et André Chagnon (FLAC) sur le rôle des organismes communautaires après la signature d’une entente entre la FLAC et l’État québécois. Nous observons qu’une des conséquences de cette entente a été de confiner les organismes communautaires à un rôle allant de la sous-traitance à la coproduction alors que, depuis vingt ans, ces organismes avaient réussi à s’établir comme partenaires centraux en contribuant, en co-construction avec l’État, à l’élaboration de politiques publiques.
A Comparative Analysis of Nonprofit Policy Network Governance in Canada
Authors: Elson Peter 
Published: April 2017

Across Canada, provincial governments and nonprofit network leaders are engaged in a “third wave” of consultations, policy dialogues, and policy alignment strategies. Unexplored to date is how nonprofit policy networks are governed and structured. Network structures could have important implications for policy management and any bilateral collaboration agreements with provincial governments. This is a new point of analysis for both public administrators and nonprofit network leaders. The alignment of network governance in four structural dimensions is analyzed, as are parallel nonprofit policy network structures within provincial governments and select nonprofit policy outcomes. RÉSUMÉ Au Canada, les gouvernements provinciaux et les dirigeants de réseaux à but non lucratif se sont engagés dans une « troisième vague » de consultations, dialogues politiques et stratégies d’alignement politique. Inexplorée jusqu’à ce jour est la manière dont les réseaux d’action publique à but non lucratif sont gouvernés et structurés. Pourtant, la structure des réseaux pourrait avoir des implications importantes pour la gestion politique et tout accord de collaboration bilatérale avec les gouvernements provinciaux. Il s’agit ici d’un nouveau sujet d’analyse, tant pour les administrateurs publics que pour les dirigeants de réseaux sociaux. Cet article évalue la division en quatre dimensions structurales de la gouvernance des réseaux, les structures parallèles des réseaux d’action publique à but non lucratif au sein des gouvernements provinciaux et certains résultats émanant de politiques à but non lucratif.

<b>POR UMA HUMANIDADE COMUM: EM DEFESA DO DIREITO COSMOPOLITA</b><br/>BY A COMMON HUMANITY: IN DEFENSE OF COSMOPOLITAN LAW
Authors: Esteves (UERJ) Pâmela S. M. 
Published: April 2017

O debate entre liberais e comunitaristas de 1980 pode ser reatualizado à luz da discussão sobre a universalidade/particularidade dos direitos humanos. A partir de Jonh Rawls, os defensores do liberalismo vêem reforçando a perspectiva da universalidade de direitos em detrimento dos projetos comunitaristas, onde o universalismo aparece como ameaça às culturas não ocidentais. A partir desse dilema, o presente artigo objetiva investigar as contribuições de um direito cosmopolita diante dessa tensão. Para tanto, buscou-se desenvolver a reflexão na seguinte perspectiva: (a) O debate liberal/comunitarista; (b) discussão da normatividade dos direitos humanos a partir de quatro questionamentos: 1-Os direitos humanos devem ser universais? 2- Os direitos humanos devem ser particularizados? 3- E ainda, se os direitos humanos devem ser universalizáveis que valores morais devem fundamentá-lo? 4- Ou se os direitos humanos devem ser particularizados como solucionar, os conflitos internacionalizados? (c) O direito cosmopolita como um referencial analítico para os questionamentos apresentados.

Published: April 2017

ABSTRACT
This project provides students with an opportunity to develop a master budget for a merchandiser. Students work in a team environment that also helps them discover budget process issues. The project consists of two parts. The first part requires students to grasp the mechanics of master budget creation and develop an understanding of how the individual budgets fit together and how information flows from one budget to other budgets. The second part of the project requires students to create new budget information when given a different organizational structure and incentive system. Both parts of the project expose students to budget process issues related to communication, cooperation, public/private information, information sharing, truth telling, and the influence of incentives on the budget process. The project is directed at undergraduate students in Managerial or Cost Accounting courses. We also present modifications that emphasize the budget process issues that would be useful for a graduate-level managerial accounting course (Master's in Management or M.B.A.).
