With the advent of the Brazilian Pre-salt oil fields, the national oil and gas industry focuses increasingly on winning the challenges in the exploitation of these new reservoirs. The well construction in this scenario involves a number of difficulties wich have been overcome consistently over time, so that it undergoes intense time reduction. The estimate is that the current time of well construction has been reduced by half since the first drilled wells and the next challenge Petrobras is willing to make is a drastic time reduction at this same rate until the year 2020. This will be possible only if new techniques are developed, as it is believed that the wells are being constructed near the limits of optimization of the current techniques. Surface casings need to be seated on the top of salt formation, which requires lengths on the order of 1000 m or more. Unfortunately, due to operating volumes related to the cement pumping volume capacity and fracture resistance of the initial soil layers, there is no return of cement to the mudline. This fact leads to free lengths of these casings with about 500 m. As the conductor casing is drilled and cemented, the well foundation resistances are sufficient to withstand the axial loads originated from the installation of additional casings and subsea equipment, since these are discharged into the conductor-soil system. The well construction time can be reduced systematically by about 2 days if using torpedo base or jetting techniques to seat the conductor. However, both soilresistance systems are insufficient to withstand axial loads installed in the well. This means that the surface casing also starts to bear axial loads of the well, which can lead to its helical buckling with a consequent increase in stress levels and undesirable displacements. The analytical formulation available for the calculation of these parameters should be put tho the test so safety can be taken into account for alternative well s foundation designs, which although more economical, should still have high reliability in the structural integrity. This work is dedicated to develop a robust numerical procedure using FEA in a commercial software, Abaqus, to evaluate the effects of high axial loads on the free length of the surface casing and the consequences of an always inevitable buckling. The ultimate goal is achieved, since the numerical analysis and a superposition of simple analytical equations demonstrate good adhesion to each other. Moreover, a clear linear dependency is found between the friction factor and the displacement of the top of the casing. This trend can be explored in future research for incorporation into analytical formulations of this parameter invariably neglected in addressing them.
