There is a vast literature on the distortionary effects of the tax-royalty system, while the effects of Production Sharing Contract (PSC) is largely understudied. Moreover, economic studies typically oversimplify the physics of the field and consequently end up with models which do not necessarily fully reflect the reality. In this study, we build a dynamic optimisation model which nests the physics of the reservoir and investigates the distortionary effects of a PSC.

The resource curse is a defining feature of the African content. Despite vast resource wealth, Africa remains the poorest and most underdeveloped continent in the world. The aim of this study is to conduct a comparative analysis of the primary laws regulating of oil and gas exploration and product activities in Angola, Nigeria and South Africa in order to determine their effectiveness in protecting the continent's depleting petroleum resources. Different regulatory models apply to Angola, following the Norwegian carried-interest model, Nigeria, where a British discretionary model has been retained, an a South africa, where a unique model has been developed. The comparison is conducted by analysing and comparing these different regulatory systems in terms of legal frameworks; the legal nature of the regulatory systems; ownership of the oil and gas resources; legal nature of licenses; organisational or institutional structures; fiscal systems; local communities benefits from these proceeds of oil and gas resources; local content; state/government participation arrangements; and environmental challenges. The study evaluates the effectiveness of these regimes by examining the extent to which they recognise and enforce state ownership of he oil and gas resourcs in situ; recognise and enforce the doctrine of Permanent Sovereignty over Natural Resources (PSNR); protect the environment; how they provide for institutional capacities for the management of resources; and the protection of local communities from exploitation and abuse by recognising their rights to benefit from revenues derived from these resources. An overall assessment of the three systems reveals that there is no ideal model for oil and gas regulation in Africa. The Norwegian model might well be considered an ideal model if it was applied with care and correctly in Angola. The study hopes to gain practical importance for the proper regulationof the oil and gas industries' upstream activities in Africa and assist governments of the selected jurisdictions in their policy revisions, as some recommendations are made. / Economics / LLD.

Notre planète recèle dans sous-sol des gisements d’hydrocarbure, à l’origine depuis près d’un siècle, de la puissance de l’homme moderne. La présente étude porte sur les modalités juridiques d’extraction et d’appropriation de ces énergies fossiles. A l’état naturel, ces ressources n’ont pas d’existence juridique propre et leurs régimes suivent celui des territoires dans lesquels elles gisent. Aussi, pour que l’extraction des gisements puise avoir lieu, il convient d’abord d’identifier les titulaires des droits sur les territoires pétrolifères et prendre en compte non seulement la diversité de ces territoires mais également la diversité des acteurs et intérêts en présence. Les détenteurs primaires des droits d’accès aux ressources identifiés, pourront alors se déployer des contrats de prospection et d’exploitation des gisements, adaptées à l’ensemble des spécificités du secteur et des particularismes locaux, aux fins notamment d’une optimalisation de l’accès aux ressources fossiles / Our planet contains underground fossil deposits powering the Modern man, since nearly a century. The present study deals with the legal issue regarding the extraction and appropriation of fossil fuels. In their natural state, these resources have no legal existence and their regimes follow the one of the territories in which they lie. Therefore, in order to extract the deposits, it is first necessary to identify the rights owners of the oil regions and to take into account not only the diversity of these territories but also the diversity of the actors and interests at stake. Once the primary access rights owners identified, deposits may be discovered and developed, through specific mining contracts, adapted to all the specific features of the sector and local particularities for the optimization of the access to fossil fuels
