Resumen
The oil wells drilling is a way of reaching a previously discovered reservoir. For this purpose, the well construction is done by a mutidisciplinary team which to well engineer to design a project so that, after being built, the well allows the fluids are produced to the surface. However, before the drilling operation starts, there are several activities which needs to be done in the first place, such as geological analysis, planning and well design, in order to estimate, in the shortest possible time, the costs to be spent with the drilling process, since these costs directly impact the total expense of an investment project in a field and can even economically cripple the project. Several studies are developed to estimate the cost of drilling a well, among them the methodology developed by Max Simon Gabbay, who in his Doctor Degree in 2015 developed an equation through a methodology that can calculate the metric cost of wells drilled during the period of 2006 to 2011 for an onshore field in the Northeast region of Brazil. In 2017, 21 new wells were drilled in this same field. This paper aims to check the validity of the cost estimate per meter for these new oil wells using the developed equation and real drilling costs. At the end, after treatment of the obtained data with te oil company, it was observed that the values estimated by the equation were 7.24% lower than the real one, concluding that the model was attended by the equation since the result is plausible even with the removal of not representative well because deviations between 5 and 10% are acceptable due to the natural geological uncertainties for a project cost estimate and the methodology of this present work has been simpler and faster.
