  • Advances in the Discrete Element Method for drilling mechanics problems 

    Oñate Ibáñez de Navarra, Eugenio; Arrufat Garcia, Ferran; Zárate Araiza, José Francisco; Ubach Fuentes, Pere-Andreu; Gandikota, Varadaraju; Ring, Lev (2013)
    Conference report
    Restricted access - publisher's policy
    We present recent developments in the Discrete Element method (DEM) for analysis of drilling mechanics problems typical in the oil and gas industry. A new local DEM constitutive model able to predict the non-linear behavior ...
  • Análisis de la correlación entre parámetros de control en máquinas pilotadoras y las propiedades resistenetes del terreno 

    Aparicio Morales, Ángel (Universitat Politècnica de Catalunya, 2009-07)
    Minor thesis
    Open Access
    En esta tesina se estudia la correlación entre los parámetros registrados durante la perforación por rotación de pilotes y las propiedades resistentes del terreno, siendo el primer trabajo publicado que conozcamos sobre ...
  • A submersible drill rig for coring soils and rocks 

    Devincenzi, M.J.; Pérez Garcia, N.; Samoili, K.; Arroyo Alvarez de Toledo, Marcos (2012)
    Conference report
    Restricted access - publisher's policy
    The paper describes the design and initial field-testing of a remotely operated submersible drill rig able to obtain continuous cores of soil and/or rock up to 6 m long. The rig mast angle is hydraulically actuated covering ...
  • Automation and control in a submarine drill rig 

    Arriaga, Aldo; Devincenzi, M.; Pérez, N.; Deu, A.; Arroyo Alvarez de Toledo, Marcos (Society for Underwater Technology, 2017)
    Conference report
    Open Access
    Remotely operated submarine drills are gaining acceptance as offshore geotechnical investigation tools for they provide a more convenient and often cheaper solution to geotechnical drilling vessels. The MD500 is an underwater ...
  • Comparison between pre-investigations and geotechnical site characterization of City Link, Stockholm 

    Arqué Armengol, Anna (Universitat Politècnica de Catalunya / Universitat de Barcelona, 2012-06-28)
    Minor thesis
    Open Access
    [ANGLÈS] The Swedish Government commissioned to Banverket the extension of the rail capacity through central Stockholm in December 2000. A commuter rail tunnel below Stockholm, the City Link, represented the solution for ...

  • 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 ...
  • Investigation of the wear of hard-metal drilling tools when drilling cast iron 

    Escursell Mor, Anna (Universitat Politècnica de Catalunya / Technishe Universität Darmstadt, 2009)
    Master thesis (pre-Bologna period)
    Restricted access - author's decision
    Spheroidal cast iron still has a lot of applications; especially in the automotive industry. In this Master Thesis the wear of the drilling tools and its effect on the quality of the drilled holes is being studied. An ...
