The oil and gas company OMV wants to introduce new technologies for wells in Romania to increase the annual production there. These new technologies should reduce the current annual intervention frequency and therefore lead to a higher annual production. This thesis deals with the estimation of the total savings and the production increase, which are caused by the employment of new technologies in Romania. These new technologies include the installation of new tubing material, the installation of new sucker rod strings and the employment of corrosion inhibitors. For every new planned action an employment scenario, which includes a best, a worst and a most realistic case, has been calculated. In addition an employment scenario for the combination of the most realistic cases has been evaluated. Afterwards a Monte Carlo Simulation has been carried out to consider how the variability of different input parameters affects various output parameters. The results of the simulation show that the oil price, the number of interventions and the intervention costs have a significant influence on the total savings. In comparison to these, the influences of the material costs are very low. The reason for this is that the savings due to the reduced number of interventions are significantly higher than the costs for the new technologies. This fact shows that enormous savings could be realized by the employment of the new technologies.
