The present study was developed aiming at distinguishing the condition of Non Productive Time NPT at drilling operations at Ecuadorian fields and recommending efforts to help decreasing Non Productive Time. The research target was collecting qualitative data from final wellbore reports, for which a classification master chart of problems called matrix was designed that organizes and solves the stuff being studied, the information was arranged according to the diameter corresponding to each section of wellbore identifying in that way the main difficulties into each section and then the cause of NPT was established by applying a technical analysis. The research was focused on obtaining the cost per hour related to NPT also, the study was complemented by adding Chi-square test in order to confirm hypothetical statements about of the relationship that could exist between the variables that cause NPT, in this way the study allows for understanding the impact of NPT through a mathematical resource.
