Abstract (sommario):
In this study, based on the work of Vogel, we generated the Inflow Performance Relationship (IPR) curves and its dimensionless form at any stage of depletion using black-oil simulator results. The IPR was generated for horizontal well with gas and water coning problems, producing from thin oil reservoir sandwiched between gas cap and aquifer. Two empirical IPR equations adopted from SPE paper by Whitson was also presented here. The first empirical relationship was developed based on simulated data for each reservoir pressure (stage of depletion) while the second relationship was developed base

Abstract (sommario):
This thesis was set to tackle the gas coning problem in oil-rim reservoirs with horizontal wells. The focus was short term production planning in the sub-critical phase only. Different controllers were developed and assessed based on the objective of net-present-value (NPV) of oil produced in the sub-critical phase.The reservoir model is a 1-D partial differential equation describing the dynamics of the gas-oil contact (GOC), for a homogeneous reservoir. Gas coning is considered to be the deformation of the GOC towards the well.Several controllers were developed and assessed alongside control

Abstract (sommario):
Water coning is a complex phenomenon that depends on a large number of variables which include among others: production rate, perforation interval, mobility ratio, capillary pressure, etc. Its production can greatly affect the productivity of a well and the reservoir at large. In fractured reservoirs, the phenomenon is more complex owing to the high permeability of the fractures in the porous media. With this complexity in mind, water coning behaviour in fractured reservoir was studied by simulating a reservoir supported by a strong aquifer using ECLIPSE-100 Black-Oil Simulator. The water cut

Abstract (sommario):
In many cases, it is important to predict water production performance of oil wells early in, or maybe before, their production life. In as much as oil field water is important for pressure maintenance purposes and displacement of oil towards the perforation of the producing well, excessive water production leads to increased cost. In the case when no provision is made, it represents a significant liability. The case considered here is a well producing from a monocline with an edge-water aquifer. Although such problems can be computed with reservoir simulation, the objective of this work was t

Abstract (sommario):
The study of coning in oil production is important because of huge water production associated with oil production around the world each year. Estimation of critical coning rate has been the subject of numerous studies and a number of correlations have been reported. This study presents a review of the current available methods for estimating critical coning rate for both vertical and horizontal wells. The various methods and correlations are compared and the assumptions on which they are based evaluated. Following comparison made between the correlations, the most reliable theories are identi

Abstract (sommario):
As part of continuing research into the flow about slender bodies of revolution, a coning motion apparatus for hydrodynamic model testing was built and demonstrated. This is the first known use of a rotary balance apparatus for external flow hydrodynamic applications. The vorticity shed by the hull and appendages creates a wake field that interacts with the velocity distribution over the vehicle's surface. This in turn effects the surface pressure distribution and thus, when integrated over the body's surface, the total force on the hull/appendage combination. It is this interaction that preve

Abstract (sommario):
Gas coning is the tendency of the gas to drive oil downward in an inverse cone due to the downward movement of gas into the perforations of a producing well thereby reducing oil production and the overall recovery efficiency of the oil reservoir. This work addresses gas coning issues in a naturally fractured reservoir via a numerical simulation approach on a single-well radial cross-section using the ECLIPSE 100 reservoir simulator. Matrix and fracture properties are modelled. Critical rate, breakthrough time and GOR after breakthrough is determined which is used to investigate the effect of m

The Conics of Apollonius remains a central work of Greek mathematics to this day. Despite this, much recent scholarship has neglected the Conics in favor of works of Archimedes. While these are no less important in their own right, a full understanding of the Greek mathematical corpus cannot be bereft of systematic studies of the Conics. However, recent scholarship on Archimedes has revealed that the role of secondary commentaries is also important. In this thesis, I provide a translation of Eutocius' commentary on the Conics, demonstrating the interplay between the two works and their authors

An affine transformation such as T(P)=Q is a locus of an affine conic. Any affine conic can be produced from this incidence construction. The affine type of conic (ellipse, parabola, hyperbola) is determined by the invariants of T, the determinant and trace of its linear part. The purpose of this thesis is to obtain a corresponding classification in the hyperbolic plane of conics defined by this construction.

The Euclidean Distance Degree (EDD) of a variety is the number of critical points of the squared distance function of a general point outside the variety. In this thesis we give a classification of conics based on their EDD, originally attributed to Cayley. We show that circles and parabolas have EDD 2 and 3 respectively while all other conics have EDD 4. We reduce the computation of the EDD to finding solutions of the determinant of a certain generalized matrix, called the hyperdeterminant of type 2 × 3 × 3. This determinant is computed using the celebrated Schläfli decomposition.<br>The Eucl

Abstract (sommario):
Cette thèse aborde le problème d’optimisation du déploiement des réseaux sans fil Mesh (Wireless Mesh Network) pour des applications large bande en milieu souterrain. Le déploiement des éléments du réseau a nécessité des études expérimentale et analytique du milieu. L’étude expérimentale nous a permis de mieux cerner la topologie du milieu, de modéliser statistiquement le signal reçu et, surtout, d’étudier la couverture radio des éléments du réseau en fonction de leur localisation dans le milieu. Aussi, du point de vue réseau, certains comportements des réseaux à sauts multiples et à plusieurs

Abstract (sommario):
This paper defines tropical projective space, TP^n, and the tropical general linear group TPGL(n). After discussing some simple examples of tropical polynomials and their hypersurfaces, a strategy is given for finding all conics in the tropical projective plane. The classification of conics and an analysis of the coefficient space corresponding to such conics is given.

Abstract (sommario):
Dentro de los procesos de formación de palabras, el mecanismo morfológico de la composición ha sido poco estudiado en el aimara y en otras lenguas andinas. Esta investigación muestra una descripción de las maneras de cómo se conforman las palabras compuestas en la gramática del aimara de Conima. Por tanto, en este trabajo se analizan la estructura y la combinatoria sintáctica de las palabras compuestas en esta variedad lingüística. La data ha sido recogida de los hablantes y de la información procedente de los principales diccionarios en aimara. En este estudio, se concluye que el aimara

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mathematics, 2005.<br>Includes bibliographical references (p. 101-103).<br>This thesis is concerned with the intrinsic structure of the De Concini-Procesi compactification of semi-simple adjoint algebraic groups and some relations with other topics of algebraic groups. In chapter 1, we study the closure of the totally positive part of an adjoint group in the group compactification. One result that we obtain is the positive property of the closure with respect to the canonical basis. In addition, we get an explicit description of

Abstract (sommario):
Negotiating boundaries: from state of affairs to matter of transit. The research deals with the everyday management of spatial uncertainty, starting with the wider historical question of terrains vagues (a French term for wastelands, dismantled areas and peripheral city voids, or interstitial spaces) and focusing later on a particular case study. The choice intended to privilege a small place (a mouth of a lagoon which crosses a beach), with ordinary features, instead of the esthetical “vague terrains”, often witnessed through artistic media or architectural reflections. This place offered the

Abstract (sommario):
Il presente lavoro approfondisce le tematiche della conflittualità e della separazione etnica, sociale, religiosa, generazionale e culturale. In particolare, riporta i risultati di ricerche condotte in alcuni degli attuali contesti urbani più carichi di tensioni conflittuali, cercando di individuare i motivi vicini e remoti del confligere, le attività messe in atto per contenere le tensioni e le relative necessità educative poste in primo piano. L’elaborato si compone di cinque parti. La prima parte consiste in una riflessione teorica sulle dinamiche che caratterizzano le interazioni sociali

Abstract (sommario):
L'évolution du débit d'une rivière présente généralement des épisodes de crues intenses, au cours desquels le débit augmente rapidement, suivis par une diminution lente du débit lorsque la pluie s'arrête. Dans ce manuscrit, nous montrons que l'écoulement souterrain dans un aquifère non confiné permet de comprendre cette dynamique. Dans le cadre de l'approximation de Dupuit-Boussinesq (eau peu profonde), la vitesse de montée de crue ˙Q est une fonction non-linéaire du taux de précipitations R : ˙Q ∝ R 3/2. Après la pluie, on distingue deux régimes asymptotiques de décrue. Au début de la décrue,
