This is the first academic study of well costs and drilling times for Australia???s petroleum producing basins, both onshore and offshore. I analyse a substantial database of well times and costs sourced from government databases, industry and over 400 recent well completion reports. Three well phases are studied - Pre-Spud, Drilling and Completion. Relationships between well cost factors are considered, including phase time, phase cost, daily cost, rig day rate, well depth, basin, rig type, water depth, well direction, well objective (e.g. exploration), and type of completion (P&A or producer). Times and costs are analysed using scatter plots, frequency distributions, correlation and regression analyses. Drilling times are analysed for the period 1980 to 2004. Well time and variability in well time tend to increase exponentially with well depth. Technical Limits are defined for both onshore and offshore drilling times to indicate best performance. Well costs are analysed for the period 1996 to 2004. Well costs were relatively stable for this period. Long term increases in daily costs were offset to some extent by reductions in drilling times. Onshore regions studied include the Cooper/Eromanga, Surat/Bowen, Otway and Perth Basins. Offshore regions studied include the Carnarvon Basin shallow and deepwater, the Timor Sea and Victorian Basins. Correlations between regional well cost and well depth are usually high. Well costs are estimated based on well location, well depth, daily costs and type of completion. In 2003, the cost of exploration wells in Australia ranged from A$100,000 for shallow coal seam gas wells in the Surat/Bowen Basins to over A$50 million for the deepwater well Gnarlyknots-1 in the Great Australian Bight. Future well costs are expected to be substantially higher for some regions. This study proposes methods to index historical daily costs to future rig day rates as a means for estimating future well costs. Regional well cost models are particularly useful for the economic evaluation of CO2 storage sites which will require substantial numbers of petroleum-type wells.

The term "sustainable development" describes certain proposals designed to provide the present generation with such needs as food, shelter, and energy while sustaining the environment or stock of natural resources for future generations. The purpose of this paper was to analyze the relationship between sustainable development and current U.S. petroleum policy. Information was gathered from newspapers, journals, government publications, and other relevant literature. The paper provided an overview of sustainable development, a history of u.s. petroleum policy, and an analysis of the congruence of sustainable development and current u.s. petroleum policy. The analysis showed that U.S. petroleum policy does not reflect the tenets of sustainable development. The paper examined three factors, other than the structure of America's government and decision-making process, that might explain the discrepancy between sustainable development and U.S. petroleum policy. These factors were widespread political inaction among Americans, negative interpretations of sustainable development, and a similarity between the intentions underlying both sustainable development and the problems it seeks to solve. The paper closed with some general speculations about sustainable development. / Graduation date: 1992

1. Introduction and Context Oil as a source of energy is an undisputed reality of the age in which we live. The oil and petroleum industry is an essential and valuable part of the South African economy. It follows then that transportation in this industry is of crucial importance. Simply put, without the efficient transportation of the various crude and petroleum products, the energy requirements of the country could not be met. While there are various modes of transportation within South Africa servicing this industry, this study will concentrate on the carriage of crude oil and petroleum products by sea, and its handiing in the associated ports. The main objective will be to examine the pricing structure raised by the ports of South Africa against the oil industry for th'a transportation of the crude and petroleum products moving through the various ports. 1.1 Background During this researcher's tenure as a shipping agent on behalf of the oil majors in the ports of South Africa, the pori authorities' charges were dealt with on a regular basis. The inherent problems with the charges and the resulting conflicts created between the port authorities and the oil majors became quite familiar to the researcher during her years of working with the two parties. 1.2 Objectives of the Study This study will start by looking at the economic theory and principles of port pricing structures. Chapter Two will work toward outlining the optimal port pricing structure a port authority should adopt, in order to ensure it is working according to sound economic principles as well as meeting the various objectives of the stakeholders utilising the port's infrastructure, superstructure and services. Chapter will focus on the South African oil industry and the importance of crude oil and its petroleum derivates as an energy source. The industry will placed in larger context of SADC, the various role players will be identified and the modes of transport used for the carriage of crude and petroleum products will outlined. The chapter will close with a presentation of the product costing for the petrol price South African consumers' pay at the petrol pumps. Chapter Four presents an overview of the ports South Africa, their facilities, their management arrangements and their pricing structures. A brief. history of the ports will be followed by a discussion of the need a restructuring process and an outline the proposed privatisation process will be Following this, the current management structure related pricing tariffs will be detailed. Chapter Africa and will explore the relationship ben.veen of the ports of South oil industry. history of this relationship will be set out, followed by the current dynamics affecting it. The study will then move on to examine the oil industry infrastructure found in these ports in terms of ownership management of Port tariffs and the question of who actually pays what will be addressed. The that created and continue to create tensions between oil majors and the ports of South Africa will highlighted. The chapter will conclude by presenting an ideal pricing structure, which could work towards resolving some of these issues. Chapter Six will discuss two different international models based on energy demand and supply similar to South African situation. The port pricing structure of these models will then be compared to that of South African ports in order to present a best-working practice. The purpose of this is to bring in an international perspective for the ideal pricing structure presented with the conclusion in Chapter Seven. 1 Methodology of the study The researcher initially used interviews with the various bodies as a means of gathering information. These data were then verified against textual information sources. Statistical figures were gathered and correlated into formats, which could then verify -, or disprove -- different hypotheses put forward in the study. / Thesis (MBA)-University of Natal, 2003.

The purpose of this study was (1) to gain a better understanding of convenience marketing in the petroleum industry in South Africa, (2) to determine whether convenience marketing has positively contributed towards Engen's business objectives, (3) and whether implementation of the concept by Engen has been successful. During this study an in-depth literature review was done to analyse convenience marketing in the petroleum industry in South Africa by using various theories and models, such as the Buyer Behaviour Models, monadic models and multi-variable models, which are helpful in creating a basic and general foundation for the understanding of consumers and the relationships between external and internal influences that may affect the purchase behaviour of a consumer. Pathway modelling is also utilised for a better understanding of consumer preferences. Extensive brand research was undertaken to identify areas of strength and weakness within the Engen forecourt c-store network. The Ansoff Market/Product Matrix was used to recommend an effective product strategy. / Thesis (MBA)-University of KwaZulu-Natal, 2005.
