Title:Mathematical models and numerical simulations of oil recovery

Since the 1990s, drilling and well completion technologies have made enormous progress. The reservoir simulation business has not kept up with these developments, and new methods for modeling more complex situations are therefore needed. Some new methods of this kind will be briefly described and discussed. This includes near well models; in particular, streamline models for near well simulation will be discussed. Such models can make use of analytical solutions of Riemann problems. Finally, such analytical solution can also be used to improve interpretation of laboratory experiments, which will be briefly discussed.

Title:Models of cell motility: From the single cell to the collective sheet

Cell motility is essential for many biological processes including wound healing, immune response, and cancer metastasis. For cells crawling on surfaces, motility involves a complex interplay between acto-myosin based force generation, adhesion to the substrate and chemical-based polarization to determine a direction. Here, we discuss our work aimed at developing integrative computational models of cell motility, ranging in complexity from simple geometrical models to complex phase-field approaches coupled to cytoskeletal mechanics. We also discuss initial efforts at using single cell models to understand the collective behavior of motile cells when they interact.
