SUMMARY:

Currently, the most diverse oil deposits are discovered in increasingly challenging environments for existing technologies. Thus, the constant development of research and technologies to support the various areas of petroleum engineering is important. The well engineering, which is responsible for designing its structure and trajectory, stands out in this work. Drilling string failure is a very costly event for the oil and gas industry, as it is necessary to stop the entire operation, which results in non-productive time. Therefore, several studies are carried out in order to predict problems during drilling. Torque, tension, compression and bending can be correctly predicted for known well geometries, but unwanted changes in well geometry during the drilling process can result in errors and uncertainties in predicting the stress state. It is proposed to predict these uncertainties in the trajectory by the statistical analysis of previously executed wells and categorized according to their correlations with each other. Performing the data analysis enables the construction of the fictitious trajectory which will be used to predict the additional forces to the loads acting on the drill string induced by the trajectory deviation.
