Petroleum development optimization under uncertainty : integrating multi-compartment tank models in mixed integer non-linear programs

Ogunyomi, Babafemi Anthony 17 February 2011 (has links)
A field development plan is an important document used to tell the share holders and investors that every aspect of the project has been carefully evaluated. The field development plan should include the objectives of the development, petroleum engineering data, operating and maintenance principles, description of engineering facilities, cost and manpower estimates, project planning and budget proposal. But to arrive at decisions concerning the contents of the field development plan many concept and ideas would have to be screened so that the best ideas and concepts are carried forward for detailed analysis. This screening process can be daunting as there is no limit to the number of viable concepts and ideas. To add to this, for a new field there is hardly ever enough data to fully characterize the reservoir at the time the field development plan is being formulated because there are only a handful of wells in the reservoir. This lack of information about the reservoir introduces uncertainty in the analysis done during the screening process of the concept selection and can have a significant impact on the quality of the project. In this work, we present a simple integrated asset model that can be used in conjunction with a proposed framework at the concept screening and selection phase of a project to evaluate the impact of uncertainty in the input variables on key project drivers. The model can be used to screen multiple concepts to arrive at a few promising concepts that point the direction for detailed studies. The application of the model is demonstrated with synthetic cases formulated for a deep water field which is at the concept selection phase. In the demonstration, we investigated how uncertainty in the reservoir thickness (NTG) and the degree of heterogeneity affect the optimal choices for initial facility size, the number of rigs and the number of pre drilled wells. / text

Role of community participation in the delivery of low-cost housing in South Africa : a case study of Soshanguve

Mashiloane, Lockson Samuel 04 June 2012 (has links)
M. Tech. / In the past the policy for the provision of low-cost housing was not very effective because the context of the development planning was characterized by fragmentation, segregation and isolation from the targeted communities. The reason for this is that these development programmes were not participatory and that they contributed to dependency rather than empowerment of communities. Selected case studies have shown that without the involvement of the community in planning and decision-making, low-cost housing projects cannot meet the needs and demands of the community for improvement in an effective and efficient way. One of the basic principles of the Reconstruction and Development Programme is that development projects should be people-driven. The policy framework clearly states that ‘delivery systems in housing will depend upon community participation’. This current study sought to determine whether delivery systems in low-cost housing projects have made this paradigm shift – that they are participatory and needs-driven. The study is descriptive and issue-oriented and is limited to understanding the process of low-cost housing provision to newly-urbanised Africans in Soshanguve, a peri-urban settlement in the City of Tshwane Metropolitan Municipality. Using a semi-structured questionnaire, interviews were conducted with 100 respondents, who were either male or female heads of households. The study gave respondents an opportunity to share their experiences regarding the process of community participation in housing provision.

A GIS-based decision support methodology at local planning authority scale for the implementation of sustainable drainage

Warwick, F. January 2013 (has links)
Implementation of the Flood and Water Management Act (2010) will place increased responsibility on local planning authorities (LPAs) in England for planning approval and future maintenance of sustainable drainage (SUDS) installations. LPAs have limited experience in assessing SUDS, and there is a need for additional guidance to support decision making. A method was developed to analyse environmental and institutional characteristics of existing published datasets using a Geographical Information System (GIS), and to create maps indicating feasible locations for SUDS devices at the strategic scale of a full LPA area. The method was applied to an example study site: Coventry, UK, covering 98.7 km2, of which 33% was impermeable, estimated from Ordnance Survey land cover. The method was reliant on the accuracy of the underlying datasets, although data uncertainties were identified, e.g. the incorrect classification of some land cover and lack of definition in private gardens. Construction of a framework allowed a structured approach to collection and presentation of information, and is a point of reference for other strategic scale investigations of SUDS feasibility. Feasibility maps were generated for SUDS in new developments, on both greenfield and previously developed land, and for retrofit of existing developments, across five main categories of SUDS: source control, infiltration, filtration, conveyance, and detention & retention. In new developments, source control, filtration and detention & retention SUDS were possible in 99% of Coventry, filtration SUDS in 95% and infiltration solutions 17%. The higher number of restrictions imposed on retrofit resulted in a smaller area where SUDS were feasible: source control 68%, infiltration 11%, filtration 64%, conveyance 57% and detention 79%. Soil impermeability and depth to water table were the principal spatial limitations on infiltration and detention SUDS in new developments. Water bodies imposed the small number of restrictions on source control, filtration and conveyance in new developments. Existing land cover was the main driver of feasible locations for retrofit. Smaller parcels of land were available for retrofit (median 35 m2) than for new development (median 100 m2). Private gardens occupied 23% of the city, forming a large part of suburban land cover. Large scale retrofit in these areas would necessitate convincing a significant number of individual landowners of the benefits of SUDS. Use of feasibility maps created using the method developed in this research might encourage more specific and earlier consideration of SUDS in the planning process. Retrofit feasibility maps, in conjunction with datasets identifying problem locations, would assist strategic reviews of SUDS options.

State–society relations in the ‘South African developmental state’: integrated development planning and public participation at the local level

Penderis, Sharon January 2013 (has links)
Philosophiae Doctor - PhD / In various formulations, the idea of a developmental state has appeared in official discourse in South Africa since the advent of democratic government in 1994, albeit that its adoption as state policy has been slow, uneven and inconsistent with the original East Asian model. What has been a feature of developmental state thinking in South Africa is the fact that the concept has been so poorly articulated in policy that it has come to mean different things to different state actors and to the public. This has been aggravated by the fact that the idea of a strongly interventionist developmental state has run counter to the idea of a diminished state enunciated in various neo-liberal policies. Moreover, unlike the authoritarian and top-down East Asian model, the government envisages a South African developmental state which is infused with democratic content where citizens assist in the formulation of policy from below. In its emphasis on a bottom-up approach to policy formulation the South African model differs markedly from the conventional idea of a developmental state which is heavily reliant on a strong central bureaucracy to drive economic growth. In the South African model local government has been assigned a pivotal role in addressing persistent economic exclusion and uneven development. A central tenet of this approach is the need for local authorities to institutionalise participatory processes at grassroots level and devise effective structures and processes to facilitate citizen participation in local affairs. In the light of the above, this thesis sets out to examine the manner in which a system of developmental local government is being implemented in the City of Cape Town. Taking as a case study the township of Delft, the study looks at the systems and processes (and particularly the process of integrated development planning) set in place to advance citizen participation. It examines the extent to which the model is perceived to be achieving its goals from the perspective of political office bearers, officials from different spheres of government and residents. The research found that notwithstanding an enabling legislative and policy framework, there is little comprehension of, or interest, in the idea of developmental local government and municipal officials largely pay lip service to participatory processes which are carried out in a top-down fashion and which neither empower local residents nor enhance their welfare. It also concluded that developmental government, in its present form, is contributing little to the establishment of a national developmental state.

Exploring the sub-national spatial and economic development impacts of the African Growth and Opportunity Act 2000 (AGOA) in Lesotho

Lekunya, Kelebone January 2017 (has links)
Rapid and sustainable economic growth and progressive social and spatial development through industrial development, has been a persistent challenge for the Sub-Saharan Africa (SSA). A commonly held "solution" to this challenge has been to provide access of manufactured goods from the SSA-region to the dynamic markets of the affluent North. This perceived wisdom led to the passing of the African Growth and Opportunity Act (AGOA) in 2000 by the 200th Congress of the United States of America. In this exploratory study, the experience of Lesotho with AGOA, with specific reference to the economic and spatial development outcomes of the Act in the country, is explored. The findings of the study reveal that the larger settlements where the AGOA-factories are located have shown little improvement, neither from an economic, nor from a spatial perspective. The same applied to villages to which AGOA factory workers sent their remittances. This was due to the meagreness of the remittances a function of the low wages paid in the factories and the resulting limited disposable income to support small-scale businesses in these villages. While AGOA did result in the creation of tens of thousands of job opportunities for unskilled and semi-skilled Basotho youth, it did not provide them with portable skills for use after leaving the factory floor. AGOA was also not found to have motivated the youth or local entrepreneurs to tap into the manufacturing sector. On the spatial development side, a number of landlords in the larger settlements subdivided their land and built residential rental units for the factory workers. Some landlords also sold their land illegally and informally, resulting in haphazard land development. The research findings suggest that, while "trade and development boosting tools", like AGOA, may be useful in providing term-based job opportunities for unskilled workforce, they will most likely not have as significant a positive impact on (1) the local economy, (2) the creation of an indigenous industrial class, or (3) the building of sustainable human settlements. Other supporting instruments, in addition to tools such as AGOA, will need to be developed locally, to achieve these goals. In addition to the research findings providing an insight into the experience of Lesotho with AGOA, they should also be of assistance to scholars and policy-makers working on the development of trade-driven tools in support of struggling regions. / Dissertation (MTRP)--University of Pretoria, 2017. / Town and Regional Planning / MTRP / Unrestricted

Planning for Sustainable Development in Senegal

Diagne, Yakhya Aicha 27 June 2013 (has links)
This thesis aims to contribute to Senegal's progress towards sustainable development planning. It presents how Senegalese planning system is structured as well as its potential and its limits to change. Senegal is a West African country classified as a least developed country. Senegalese decision-makers seek to provide economic and social well-being to their population, while ensuring a rational and sustainable use of ecological resources. They have demonstrated their commitment to sustainable development in official planning documents and several development programs. However, the process towards sustainability faces several constraints. The structure of the development planning system is complex and rigid; involving a plurality of state agencies, local entities, advisory bodies, citizens, and parliamentarians whose work is uncoordinated and inefficient. Furthermore, a tension exists because the political organization is based on a social vision, while development actions are derived from a liberal policy. In addition, planners and decisions-makers do not share the same understanding of sustainable development. The situation is made more complex by international influences on the concept of sustainability that call for the integration of principles such as gender equality and universal education, making it difficult to establish a clear and commonly understood approach to sustainability. While Senegal seeks human, technical, and financial resources from international donors, the conditions of financial foreign partners further complicates the development planning system. / Master of Urban and Regional Planning

Rural Development Planning and Labour Absorption: O'Higgins and Colchagua Provinces, Central Chile

Nunez, Matilde 07 1900 (has links)
<p> During the last several decades, Chile has experienced development characterized by rapid social and economic changes. In conjunction with economic growth, Chile has experienced rural stagnation, a growing dependence on imported foodstuffs and a migration of rural population to the urban centres. Unemployment and underemployment exist in both the rural and urban sectors.</p> <p> Economic planning in Chile must be directed in part to improving agricultural production, reducing the dependence on imported foodstuffs, and creating more employment opportunities in the rural sector.</p> <p> In this paper, the Chilean provinces of O'Higgins and Colchagua are examined with regard to the determinants of labour demand. A measure of rural unemployment (CH), calculated for thirty-two townships is analysed and evaluated as a planning tool. Variations in the demand for labour and the estimated levels of unemployment (CĤ) are analysed with reference to the physiographic characteristics of the townships, land use, and the system of land tenure.</p> <p> It was found that spatial distribution of the supply of labour is a function of the location of labour demand and that surplus labour tends to move toward the minifundios and the urban areas. Land use and the choice of technique appear to be strongly influenced by land tenure and access to markets in addition to being determined by land capability. The paper concludes with a discussion of the planning and policy implications of the study.</p> / Thesis / Master of Arts (MA)

The Millennium Development Goals and Development after 2015

Poku, Nana K., Whitman, Jim R. January 2011 (has links)
Five years from the end of the 15-year span of the Millennium Development Goals (MDGs) it is already plain that progress has been patchy and that the larger goals will not be met. The scale and profile of the MDGs will make them subject to eventual success or failure judgments and 'lessons learned' analyses, but the evidence of the past decade and current trajectories are sufficient to reveal our conceptual and operational shortcomings and the kinds of reorientation needed to ensure that the last five years of the MDGs will exhibit positive momentum rather than winding-down inertia. Such reorientations would include prioritising actors over systems; disaggregated targets over global benchmarks; qualitative aspects of complex forms of human relatedness over technical 'solutions'; and the painstaking work of developing country enablement over quick outcome indicators, not least for the purpose of sustainability. Thinking and planning beyond 2015 must be made integral to the last five years of the MDGs, for normative as well as practical reasons.

Students' representations and experiences of personal development and PDP at one British university

Jankowska, Maja January 2012 (has links)
Those who teach in Higher Education in the UK face with the growing internationalisation and diverse landscape of the sector as well as an obligation to provide students with opportunities for personal, professional and academic development. Whilst a great deal has been written about both internationalisation and Personal Development Planning (PDP), a structured and supported process, which is intended to enable individual students to reflect upon their learning and plan for their future (QM, 2000), relatively little is known about international students' perceptions and experiences of such development and planning. This thesis aims to explore issues that are under-represented in the literature, experiences, perceptions and meanings of personal development and PDP among international students, and cast some light· on the complexities of individuals' development and growth. It employs a broadly phenomenological perspective, attending to individual representations and understandings of a small group of culturally diverse students in one university setting, captured with the use of qualitative research methods (concept maps and interviews). Methodologically, it attends to the researcher's specific insider/outsider positioning and highlights reflexivity as the key feature of the research process. It documents the research journey in a transparent and conscious way, evidencing the methodological experimentation and the development of the researcher. This research raises key questions about uncritical application of concepts such as PDP as well as other pedagogic practices in increasingly diverse classrooms that are underpinned by Western philosophical and scholarly traditions. It challenges a narrow perspective of personal development as centred on agency, individuality, self-promotion, independence and personal achievement and gain by inviting a consideration of personal development and learning as socially constructed processes with a wider range of purposes than traditionally articulated by PDP. It also challenges the perception of international students as 'bearers of problems' and 'empty vessels' and contributes to the shift in the literature from the rhetoric of blame and deficiency to the rhetoric of resource - respectful of students' experiences and knowledge. Whilst not claiming generalisability from a small sample of participants, this project nonetheless has broader implications for researching and teaching across cultures, raising awareness of complexities of multicultural education. In this research I focus on students' ideas of personal development (PD) and personal development planning (PDP). By looking for things that support, not hinder their personal, professional, social and academic development I am able to offer some insights into students' conceptions, beliefs, experiences, hopes and aspirations and suggest ways of improving educational practice (especially in terms of PDP).

The effectiveness of the integrated development planning (IDP) as a tool to accelerated service delivery : a case study of Aganang Local Municipality in Limpopo Province / Mahlaku Anna Mojapelo

Mojapelo, Mahlaku Anna January 2007 (has links)
The research focuses on the effectiveness of the integrated development planning (IDP) as a tool to accelerated service delivery: A case study of Aganang Local Municipality. The main problem investigated in the research is that the community of Aganang Local municipality does not have adequate services. The objective of the research is to investigate the integrated development planning process's impact on service delivery, to investigate if the budget is aligned to the IDP and to make possible recommendations on how the IDP could accelerate and improve service delivery. The hypothesis of the research centres on the acceleration of service delivery by implementing the IDP. Change in integration and cooperation in municipalities can be met if the management, process, systems, culture and innovation are improved. Qualitative and quantitative data was used in this research; the primary sources include questionnaires and interviews while the secondary sources include books, journals and reports. The findings revealed that Aganang local municipality has limited capacity in terms of human and financial resources; the municipality should have a retention and succession policy to ensure that the skills in the municipality are retained. The research also revealed that most people in the municipal area are illiterate and have insufficient skills. The study also revealed that the sector departments do not ensure that municipal strategies take cognisance of provincial strategies during the strategic sessions. The study also revealed that the budgets are only done per financial year and not on a Medium Term Expenditure Framework (MTERF) basis (3-year plan) and are not properly aligned to the IDP. The research recommends that municipalities should strengthen the inter-governmental relations to ensure alignment and integration both horizontally and vertically. The research also recommends that the municipality should build capacity and develop skills in the community. The study also recommends adopt the cluster planning and implementation including forward planning to ensure that there is maximum resource allocation and shared functions. The study also recommends that the budget should be on a three-year basis to allow for proper project planning. / Thesis (M.Art. et Scien.
