  • A coupled CFD-DEM model for sand production in oil wells 

    Climent Pera, Natalia (Universitat Politècnica de Catalunya, 2016-10-17)
    Doctoral thesis
    Open Access
    During the oil recovery a hole is drilled, the sandstone is left unsupported next to the cavity and disloged sand grains can enter the oil recovery system. This process is called sand production and several problems may ...
  • Fluid effects in sand production simulations coupling DEM with CFD 

    Climent Pera, Natalia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; O'Sullivan, Catherine (CRC Press Taylor & Francis Group, 2014)
    Conference report
    Restricted access - publisher's policy
    Sand production around a wellbore is here simulated using a three dimensional numerical model based on Discrete Element Method (DEM) coupled with Computational Fluid Dynamics (CFD). The model is calibrated against a ...
  • Sensitivity to damping in sand production DEM-CFD coupled simulations 

    Climent Pera, Natalia; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio (American Institute of Physics Conference Proceeding, 2013)
    Conference report
    Restricted access - publisher's policy
    A three dimensional numerical model based on Discrete Element Method (DEM) and coupled with Computational Fluid Dynamics (CFD) was implemented to simulate sand production. Simulations with no fluid flow conditions and with ...
