Abstract:

For the past five years, Engineering students from Barcelona School of Civil Engineer in UPC BarcelonaTech have shown that educational intervention in first-year engineering programs can positively affect students’ awareness of Science, Technology, Engineering and Mathematics (STEM) concepts by introducing students to basics concepts and motivating them to follow next ones. At Terrassa School of Industrial, Aerospace and Audiovisual Engineering, also belonging to UPC BarcelonaTech, STEM concepts are strengthen to high school students by means of the Mercat de Tecnologia, (a science fair among schools) and by some recommended but not compulsory propaedeutic courses of basic subjects, carried out the week prior to the official start of university studies. Still, many students entering university show some lacks on theoretical items, particularly those who do not follow the usual way to access to tertiary studies after obligatory secondary education but a parallel and more practical one. In fact, there is a large heterogeneity in terms of the average previous knowledge of every subject as well as in the individual curriculum of each student, since they might have enrolled different courses before entering the university. Due to those lacks, some professors at both aforementioned schools have developed a MOOC oriented to new university students. The designed MOOC is useful in order to improve the basic knowledge of new students regarding these sciences.]]>

Abstract:

The mathematical background of international students in Technical Master programs is pretty heterogeneous. They often lack of a sound basis in specific topics, which are necessary to follow the Master. Filling this gap is often stressing because it requires these students to make an additional effort reviewing basic references. The goal of this initiative is to produce a tailored learning tool for these students. Previous experiences of the proposing teams suggest that using a Moodle environment is a suitable choice to develop the tool. The idea is to cover synthetically the topics and to allow getting acquainted with the knowledge in a straight-to-the point approach. T.I.M.E. is a network assembling more than 50 Higher Education Institutions (mostly in Europe) with a focus in Scientific and Technical training. T.I.M.E. provides an ideal framework for developing and testing the tool. This is because the contents are enriched by the feedback of the experience of the members involved. Moreover, T.I.M.E. community is a perfect test bench for the tool.]]>

Abstract:

One of the most important aspects in the management, planning and analysis of the environmental impact of oilfields exploitation is the reliable prediction of its behavior. The most used methodology to reach this goal is numerical simulation. It is important to notice that a large amount of time to perform these kinds of simulations is spent to obtain a geometrical digital model of the terrain (definition of the boundary, localization of faults, cavities and horizons that define different strata, injection and extraction wells, etc) and to generate a mesh adapted to the needs of the simulation. Usually, the most used techniques to obtain geological data may introduce incoherencies as well as important precision errors. For this reason, it is necessary to develop an environment that allows the effective manipulation of such information. In addition, another important issue with this kind of problems is that near the extraction wells and around the faults in the domain, there are large gradients of pressure which may give rise to large changes in the velocity field. In order to correctly capture these abrupt variations, that may significantly affect the reliability of the obtained results, commercial software tends to generate meshes that contain a large number of small elements, because they rely on first order methods. This leads to prohibitively high computational costs to obtain predictions with the required precision. The hybridizable discontinuous Galerkin method (HDG) is specially designed to overcome these issues. First, the high order polynomials allow to approximate the physical quantities of interest with higher precision and using fewer elements. Second, the discontinuous formulation allows to use a different polynomial degree in each element, thus the solution is captured adaptively with the required precision. Third, the hybridizable formulation allows to reduce the computational cost of the simulation. This project is devoted to the development of high-order numerical techniques for the efficient and reliable simulation of the behavior of oil reservoirs. We propose to develop a simulation environment that allows to compute realistic scenarios, increasing the reliability of the results and reducing the computational resources. In this way, it will be possible to analyze more configurations and to increment their complexity. In conclusion, the incorporation of these methodologies will allow to increase the range of applicability and usability of the numerical simulations. To this end, we set the following objectives: 1. To develop an application that allows to generate a geometric digital model of the region of interest from the information obtained from the geophysical exploration methods and the production control systems. 2. To develop a 3D high-order mesher algorithm to discretize the geometric model obtained in the first objective. 3. To develop a code to simulate multi-phase (water, oil and gas) and multi-component (different types of oil) porous flux problems by means of a 3D HDG formulation. 4. To integrate the techniques developed in the previous points in a simulation environment for the planning and environmental analysis of oil reservoirs and to use the simulation environment to study realistic cases of industrial interest. This project has the explicit support of two EPO: the "Institut de Catalunya Energy Research, IREC" and "PetroSoft".]]>
