Abstract: In this talk an adaptive mixed finite element method will be introduced for the Darcy flow in a two-dimensional fractured porous media. The discrete fracture model (DFM) is applied to model the fractures by one-dimensional fractures in a two-dimensional domain. We derive a robust residual-based a posteriori error estimator for the problem with non-intersecting fractures. Then applying the adaptive algorithm, we will further introduce an efficient upscaling algorithm to compute the effective permeability of the fractured porous media, and a two-scale reduced model for simulating the flow in the porous media with conductive fractures. Several numerical results will be shown to demonstrate the efficiency of the adaptive algorithm and the proposed two-scale model.

Abstract: The exploration geophysicist is already a stereotype that needs to be left in the past, giving space to a refreshed professional with new skills and equipped with the language of reservoir engineers, drillers, and ecologists. This is key for sustainability strategies in global energy supply and for enabling the planet’s ecosystem preservation guidelines.
Over the decades, geophysicists have faced an ever- evolving rollercoaster, generally but not always tied to oil prices, that has placed them in high-salary oil-and-gas-sector jobs. The originally indispensable roles of geophysicists as key workforce components in exploration departments of operating companies has now shifted immensely. Earlier, they were tasked with nding important volumes of oil and gas reserves. There were no rivals in supporting corporate expansion strategies for joint ventures or acquisitions other than the knowledgeable geophysicists, able to present the secrets of the subsurface as colorful answers, worthy of approvals. Today however, the exponential growth of unconventional reservoirs and maturation of oil elds worldwide that require enhanced production schemes, in conjunction with more ecologically friendly government policies that impose useful constraints, have pushed a clear shift in the skills and focus needed for geophysicists not only to survive but to thrive in new energy scenarios.
The purpose of this lecture is to analyze how the main milestones and recent developments in the energy market have challenged and continue to challenge geophysicists in industry and in academia. The focus of the lecture is to explain how the new eld development strategies of the main actors in oil and gas inevitably will impact the utilization of geophysicists. Several ags will be raised about the increasing need for ensuring availability of industrial and potable water as well as prevention schemes with respect to contamination, ooding, earthquakes, and volcanoes and their impacts on urban areas.
Is academia preparing geophysicists for current and future challenges? Is the energy sector suf ciently engaged in maximizing the use of geophysicists? How aware is society as a whole of the value of geophysicists in urban disaster prevention plans? These topics and more are explored in this lecture.

Abstract: We study mathematical models and their finite element approximations for solving the coupled problem arising in the interaction between fluid in a poroelastic material and fluid in a fracture. The fluid flow in the fracture is governed by the Stokes/Brinkman equations, while the poroelastic material is modeled using the Biot system. We present several approaches to impose the continuity of normal flux, including an interior penalty method and a Lagrange multiplier method. A dimensionally reduced fracture model based on averaging the equations over the cross-sections will also be presented. Stability, accuracy, and robustness of the methods will be discussed.
