A Fully Coupled XFEM-EDFM Model for Multiphase Flow and Geomechanics in Fractured Tight Gas Reservoirs [PDF]
Procedia Computer Science, 2016 AbstractUnconventional reservoirs are typically comprised of a multicontinuum stimulated formation, with complex fracture networks that have a wide range of length scales and geometries. A timely topic in the simulation of unconventional petroleum resources is in coupling the geomechanics of the fractured media to multiphase fluid flow and transport.We

Introduction aux équations différentielles fonctionnelles mixtes EDFM. [PDF]
, 2017 Les équations différentielles fonctionnelles mixtes ont deux types d’arguments : argument retardé et argument avancé, qui ont un comportement différent. Comparativement à l’équation différentielle fonctionnelle à retard, l’équation différentielle fonctionnelle mixte EDFM, n’a pas fait l’objet de beaucoup de recherches mathématiques.
