The aim of this paper is to present the evaluation of feasibility of hydraulic fracturing job in Colorado Field wells. For this reason, it was considered for a hydraulic fracturing treatment in Colorado’s wells to be successful you must fulfill two criteria: the fracture has to be technically enforceable and economically feasible.With a production model there were selected the Wells that presented greater potential to reduce the damage in the wellbore. Later the technical evaluation was made by geomechanical characterization of lithological column which allowed setting: pore pressure, mechanical properties and stress. Intervals were selected to intervene using the petrophysical model. Within these intervals it was evaluated the feasibility of generating a hydraulic fracture by determining the type of initial failure of the rock, presence of high containment barriers of height, fracture gradient and contrast of mechanical properties.According to the Unified Fracture Design methodology it was designed the optimum fracture geometry which maximizes the well productivity. This potential incremental design was used to evaluate the economic feasibility of fracturing which allowed to establish whether the initial investment and operating cost of treatment were recovered during the treatment time.
