This thesis examines the results of the future exploration drilling activities expected to be committed between 1995-2014 in the mature areas of the UK North Sea. The study employs Monte Carlo simulation techniques to quantify the risk of exploration ventures by estimating the expected value of the exploration decisions in a mature hydrocarbon province where both the exploration success and the size of the discovered fields are shown to be diminishing with advancing exploration. The study explicitly takes into account the risks which are associated with both geological and economic uncertainties. The prime objective is to model and forecast the significant quantities of oil, condensate, and gas to be discovered given the specified levels of committed exploratory effort. Due to the presence of different geological and prospectivity characteristics, the whole North Sea province is divided into three basins namely the Southern, Central and Northern basins each of which has been treated and studied separately. The commercial merits of the future discoveries for potential development purposes have been determined through the application of different parameters for future oil and gas prices, various costs of field exploration and development, etc. The impact of the fiscal regime on the commercial viability of the future discoveries has also been explicitly examined. After identifying the future discoveries with commercial significance in the North Sea, their resulting production, costs, revenues, tax bill, and the net present values are presented in detail. To create a wider picture for the new field discoveries and their eventual contribution to the overall production in the North Sea, the future exploration and production activities have been examined under three different scenarios each reflecting varying geological and economic circumstances.

Dans cette thèse, nous introduisons le concept de Réalité Augmentée Haptique (RAH) en définissant une taxonomie à deux axes. Le premier dénommé Haptique Augmentée (HA) représente l’ensemble des applications qui modifient/augmentent une donnée haptique existante. Le second axe, appelé Augmentation Haptique (AH), considère les applications qui utilisent la modalité haptique pour fournir une information supplémentaire à l’utilisateur. Par la suite, nous illustrons ces concepts sous forme d’une application de télé-diagnostic, permettant l’exploration d’un objet mixte, composé de parties réelles et virtuelles, ou la comparaison entre un objet réel et un virtuel ; d’un nouvel algorithme pour l’enseignement d’un chemin par guidage haptique, tout en évitant les problèmes de passivité et de dépendance de l’apprenti ; et de l’emploi de ces deux notions dans une application de peinture virtuelle sur un quelconque objet réel (avec croisement d’augmentations visio-haptique), le tout enrichi d’un processus visuel de Réalité Diminuée. / This thesis introduces the concept of Haptics Augmented Reality (HAR) defining a taxonomy of two concepts. The first called Enhanced Haptics (EH) consists in applications that enhance/modify/… an existing haptic data. The second concept, named Haptic Enhancing (HE), considers applications using the haptic channel to provide additional information to the user. Thereafter, these concepts are illustrated as a tele-diagnosis application, enabling the exploration of a mixed object, composed of real and virtual parts, or the comparison between a real object and a virtual one; as a new algorithm of haptic guidance dedicated to path teaching scenarios, avoiding the problems of passivity and dependence of he apprentice; and the use of these two concepts within a application of virtual painting onto any real object, enriched with a visual Diminished Reality process.
